COVER STORY conducted internationally in these industries, issues like international market expansion, global supply chain, and regulatory developments must be in focus. LEVERAGING LOCAL EXPERTISE Today it is common for equipment manufactures to produce in and sell to markets with wide geographic spread. As more mergers and ventures are set up to meet global demands, this trend is rapidly changing the marketplace. Managing the supply chain for global enterprises includes establishing production and inventory facilities close to customers. Large OEMs need to procure component suppliers that offer competitively priced products nearby. This is one reason Danfoss has more than fty factories in 23 countries in North America, South America, Europe, Asia Pacic and Africa, and has made it a core part of its strategy to set up man ufacturing operations close to its markets. But local production is only part of the picture. A global sales and support network is integral to meeting demands within each of the worldwide markets. Although transportation and communi cation advances are closing distances A century ago colonial empires, most notably the British Empire, drove the structure of global commerce. Today, almost any thing can be produced in almost any part of the world, a reality that has changed the face of commerce. There are about 150 free trade agree ments in effect worldwide, including NAFTA, ASEAN, and the European Union. These agreements have helped to create a business environment where business ows around the world in every direction. According to World Trade Organization statistics, the value of world merchandise exports was 6. 2 trillion in 2000, while world exports of commercial services was 1. 4 trillion. In the industries Danfoss serves, the global economy shapes how daily busi ness is conducted. The world demand for commercial refrigeration equipment, for example, is expected to increase to 6. 2 percent per year through 2004, when total shipments are expected to reach 25. 1 billion, according to the Air Conditioning Refrigeration Institute. The worldwide market for electronic motor drives is expected to grow from 12. 5 billion to 19. 1 bil lion by 2005, according to a study by Drives Research Corporation. With such an enormous amount of business In todays global economy, Beijing is an arms length from Baltimore and Copenhagen is just a jump from Chicago.

In order to have impact on world markets, a company must be attuned to different cultures and business practices. Not only must they meet local product development needs, but they also must conduct business in accordance with local requirements in labor relations, government regulation, negotiations, and sales approaches, among other things. In order to meet the demands of a global marketplace, Danfosss strategy is not only to manufacture close to markets but also to leverage local talent and expertise whenever possible, says Danfoss corporate spokesman Ole Daugbjerg. As part of its commitment to responsi ble global development Danfoss recently joined the Global Compact, an international initiative to foster corpo rate citizenship and global responsibil ity spearheaded by the United Nations. The Compact, launched by the U. N. Secretary Ko Annan in 1999, brings companies together with U. N. agencies, labor, and nongovernmental organiza tions to foster cooperation and devel opment in human rights, labor and the environment. read more about the Global Compact on page5. GLOBAL BUSINESS IN DAILY LIFE The expansion of business internation ally affects not only industries, but also the people they serve. People in devel oped countries have increasing access to imported products, whether it is blue jeans, appliances, or basic necessities like food and water. Global demand for different food prod ucts has increased due to changes in income levels, expanding populations and improved transportation methods. When a family in a developed nation puts a meal on the table, its likely that the food has come from many different countries. According to the World Health Organization, food imports to the United States still account for a relatively small share of the U. S. diet just over 9 percent but that is rising. In contrast, imports supply about 60 percent of the calories in the Japanese diet. Like other products, food can travel long distances thanks to global com merce and refrigerated transportation, but it is essential that the product is kept in safe storage at the right temper ature throughout the entire process. A January 2002 World Health Organization Report, states that governments throughout the world are intensifying efforts to improve food safety, including reducing foodborne illnesses. This includes biotechnology and food production advances. Refrigeration is also an important part of making sure the cold chain is safe and that imports meet health standards of the countries where they are consumed. Refrigerated transporta tion, therefore, has a major impact on global food trade and on global health. Water supply is another area where global trade affects peoples daily lives. Technologies and new products in water treatment have made it possible for people in remote corners of the world to have access to safe, potable water. There is still an enormous need for clean water supply in undeveloped and developing nations. But as technol ogy progresses and global commerce spreads, the situation is gradually improving. Many factors, from politics to commu nications technology, will affect how the global economy will take shape in coming centuries. In the meantime, doing business on a global scale continues to shape the way we live and work every day. 2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=6http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=6AIR CONDITIONING REFRIGERATION Successful suppliers to both established and emerging global businesses must provide products and services that meet the needs of global operations. This is the most important reason that Danfoss engages in global product development. Global development is the course Danfoss chose to bring to market the new second generation of ADAPKOOL AK2 electronic controls for supermarket applications. The research and development team is truly global, with work coordinated between groups in the United States, the United Kingdom, and Denmark. There are clear benets for Danfoss and its customers. More than 50 engineers work as a single RD group, dividing the tasks among multinational groups. There is no duplication of effort, as a single product platform has been designed that will be delivered worldwide with regional modications to software. OEM customers who manufacture racks and cases in one country can more easily deliver products made with Danfoss electronic controls to any part of the globe. The Danfoss controls meet all applicable regional codes, and users will be able to program in a variety of languages. Because of the unity of effort and the size of the development group, there is a shorter time to market. Products are realized faster and with more features. And because Danfoss is able to coordinate supplier selection with development and manufacturing tasks, and to purchase in greater volume with the single global product platform, prod ucts are delivered with greater cost efciency. Successful businesses increasingly provide products and services in multiple markets around the world. World markets are coalescing to form a single global market for many companies. 4Vol. 1 Issue 5Danfoss Dependable. Meeting Demands of Worldwide Markets2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=7http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=7Vol. 1 Issue 55Danfoss Dependable. Global Compact is an international initiative spear headed by the United Nations to foster corporate citizenship and global responsibility. Danfoss has joined this effort, which calls on business leaders around the world to work together for sustainable global development. The Global Compact is an excellent platform for nourishing our long associa tion with social responsibility and sustainable development, says Ole Daugbjerg, Danfoss corporate spokesperson. U. N. Secretary General Ko Annan launched the Global Compact in 1999 in an address to The World Economic Forum. The goal is to bring together com panies, U. N. agencies, labor, and nongovernmental organizations to foster action and partnerships. Danfoss President and CEO Jrgen Clausen has signed a letter to Annan that commits the company to support and work for the nine principles embraced in the Global Compact Support and respect the protection of international human rights within our sphere of inuence Ensure our corporations are not complicit in human rights abuses Support freedom of association and the effective recognition of the right to collective bargaining Eliminate all forms of forced and compulsory labor Effective abolition of child labor Eliminate discrimination in respect to employment and occupation Support a precautionary approach to environmental challenges Undertake initiatives to promote greater environmental responsibility Encourage the development and diffusion of environmentallyfriendly technologies To manage the process, it helps that the Danfoss supermarket development groups have been sharing expertise for years. Danfoss has operated interna tionally for more than fty years, says Henrik Christensen who directs product development, qual ity, and manufacturing at Baltimore. The whole AK2 effort is enabled because each of the three groups, in England, the US, and Denmark, under stands the culture of the other, and the common Danfoss culture. We have the same work ethic. With the same goal, and a unied product approach, it is not surprising that we have a success with AK2. Paul Friedlander has a lot of experience in develop ment, but only two years at Danfoss. He joined the company in 2000 when Danfoss acquired Energy Controls International, and is now project manager at Baltimore. Its quite simple really, he says. The opportunity is the challenge. I rmly believe that broader input leads to better solutions and the diversity of global product development guarantees broad input. The question is How do you harness energies from different cultures and perspectives and successfully drive a task without losing focus The question has been answered many of the new AK2 products were on display at Octobers IKK show in Nuremberg, Germany, with subsequent availability in North America. global compact The second generation of ADAPKOOL has been a global effort. 2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=8http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=86Vol. 1 Issue 5Danfoss Dependable. HEATING WATER A round the world people warm and cool their homes with different technologies. Before the advent of mechanical heating and airconditioning systems, people rst relied on simple shelter, then on open res, blankets, and ice to improve their comfort. Today, homeowners can adjust room temperature and humidity to individual pref erences. Here is a look at some of the various heating and cooling systems used around the world and a little history of their development. In North America many of todays homes are heated and cooled with forcedair systems that run on electricity, natural gas or oil. A central furnace, usually located in the basement, heats the air and has a fan powerful enough to distribute the conditioned air through a duct system that serves every room in the house. This same distribution system can be used to transport cool air supplied from an air conditioning unit usually placed outside the home. Some homes are heated by a boiler that supplies hot water or steam to radiators throughout the house. Radiators heat by convection air circulation and by radiation. Another form of heating that conducts by radiation and convection is the modern wood or coal stove made popular in recent years by the desire to avoid increasing energy costs An increasingly popular way to heat homes is with hydronic systems that distribute heated water through radiators or tubes located underneath the oor. The latter is commonly referred to radiant oor heating. An increasing number of homes today use radiant oor heating for part or all of their requirements. In these systems, hot water from a boiler passes through tubing laid beneath oors. Using a system of zoning valves or pumps and thermostats, each rooms temperature is controlled by regulating the ow of hot water. According to a DOE brief, these modern radiant oor systems distribute heat more precisely than hot air systems, radiators, or wood stoves. As technology and wider use lower the cost of equipment and installation, hydronic oor heating is nding a place in more new homes in North America. The concept of oor heating dates from the Roman Empire, when heat was channeled beneath the oors of a variety of dwellings from villas to apartments. Todays systems apply modern technology to that same concept. Although Danfoss, which supplies controls for all kinds of residential and commercial heating systems, has seen a marked increased demand for oor radiant systems in North America, the trend has developed here much later than in Europe, where radiant heat has been popular for decades. In Western Europe more than 50 percent of all new construction incorporates hydronicbased radiant heat. Although North Americans have been slow to recognize the comfort and ef ciency of radiant heating systems, the sale of radiant tubing has doubled in the last 4 years. Danfoss, which supplies controls for all kinds of residential and commercial heating systems, has seen increased demand for oor radiant systems in North America and has developed a In North America many of todays homes are heated and cooled with forcedair systems that run on electricity, natural gas or oil.

District Heating Many North American homes have central heating and cooling systems. In other parts of the world, however, it is common to be linked to a districtwide heating system. A district heating system provides many buildings with heat from a central boiler plant operated by a public utility company. The heat is distributed through insulated pipes to a subdistribution center and then to individual buildings and homes. District heating was rst used in the United States and is still found in some urban centers. Consolidated Edison of New York Con Ed operates the largest district heating system ever built, apart from those built in centrallyplanned communist states. The system has operated since 1882 and serves New York Citys Manhattan Island from the Battery to 96th Street. In addition to providing space and water heating, steam from Con Eds plant is used in restaurants for food preparation and is supplied to power absorption and steam turbine chillers for air conditioning. But, overall, district heating is on the decline in the United States. For district heating to be a viable solution, demand must be concentrated to keep down dis tribution costs it is an economic chal lenge to use district heating in suburban areas. Conversely, in Western European countries like Denmark, Sweden, Finland, Germany, and the Netherlands, where populations are more concentrated, use of district heating is increasing. And though Eastern Europe and the former Soviet Union have long used district heating, most of those systems use old technologies. District heating is attractive in Europe for several reasons, including a tradition of very longrange planning by strong central governments and the fact that many European countries do not have cheap sources of oil or natural gas. Some countries are dominated by district heating. In Iceland, more than 85 percent of houses are connected to one of the 32 district heating systems in the country. Geothermal energy is the source for most of the district heat there, while electric boilers are a principal source of the remainder. Asian countries like Korea, Japan, and China, also have developed district energy cultures. In China the district heating supply has expanded from about 6 percent in 1994 to 62 percent in 2001. Cool Homes North Americans make up the largest market for air conditioning. Air condi tioning is more than a luxury it can save lives, especially in high heat, high humidity areas such as Houston, Texas, and Miami, Florida. The economic development of these areas did not begin until airconditioning was widely avail able. According to the Environmental Protection Agency, in the United States, an average 1000 people die from the cold each year, while twice that many die from the heat. Although central cooling in ofce buildings existed as early as 1928, it was too expensive for the typical home owner later, people went to theatres or shopping centers to cool off. By the mid1950s, large numbers of Americans began to live in airconditioned homes. By 1960, 12 percent of the nations homes were airconditioned. Today 80 percent of Americans live in air conditioned homes. Most central air conditioning units split systems with the condensing unit compressor, condenser, and a condenser fan outside, and an evaporator coil mounted at the furnace. The furnace blows air through the evaporator coil and throughout the homes duct system. While setup works well with the tradi tional forcedair system, a home without forced air heat with radiant oor heating, for example would need to install separate airconditioning. In dry climates, by using chilled water, radiant oor systems can be used for cooling as well as heating, but the application has limitations. Airconditioning is gaining popularity outside of North America, especially in commercial buildings. Cooling is not common2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=10http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=108Vol. 1 Issue 5Danfoss Dependable. AIRCONDITIONING REFRIGERATION In Control, from Lunar Stations to Remote Thirdworld Villages T aking ideas from earth to space and back, David Bergeron is an innova tive entrepreneur with a solid record of achievement in technological solutions. A 1980s graduate of Texas AM in aerospace engineering, Bergeron began working with NASA in his junior year and after graduation worked in aerospace on thermal and power systems. He is founder and president of Sun Danze Refrigeration still building highefciency refrigeration systems for space, but bringing them down to earth as well. While work with NASAs Advanced Refrigerator Technology group, Bergeron developed refrigerators and cooling systems for space stations and was awarded three patents. Because batteries arent desirable in a space missions weight budget, these appliances are powered only by solar energy. The refrigerators need to be hyperinsulated, and an efcient thermal storage medium is required to keep contents cold when there is no sunlight for power. Compactness and light weight have high priority in design. For an engineer, these are fascinating opportunities to provide solutions. To the businessman, it immediately seems that there are very few customers. Although it is almost certain that NASA and others will go back to the moon, right now space travel is, to say the least, somewhat limited. Downto Earth Solar Refrigeration While maintaining its operations for space, Sun Danze has made a viable business out of downtoearth solar refrigeration. Around the world today there are 1. 7 billion people without electricity. Even though emerging countries have added thousands of homes to their electric grids, there are large areas that are not yet electried, including thousands of remote villages from 20 to 100 people. The per capita cost of power lines to these areas is prohibitive for the governments. Instead, grants are offered to each home so that limited alternative power and solar appliances can be installed. Once they have electric light and radio, many people next want a refrigerator. A Sun Danzer refrigerator or freezer has truly global provenance. Design work is done at the Sun Danze headquarters in Sparks, Nevada the cabinet is manufactured by Electrolux of Sweden a BD variable speed DC compressor comes from Danfoss in Flensburg, Germany. Danfoss provides application engineering support from its While work with NASAs Advanced Refrigerator Technology group, Bergeron developed refrigerators and cooling systems for space stations and was awarded three patents. 2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=11http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=11ofces in Baltimore, Maryland. The market, as we have seen, is worldwide. While building his earthbound business, David Bergeron has continued to work on projects for the space program, espe cially in airconditioning for a lunar base. About the size of four tour buses, the current lunar station concept embodies a closedloop life support system. For the airconditioning appli cation, Bergeron has chosen a high voltage direct current refrigeration system that is powered by a photovoltaic array and uses a Danfoss AKV electronic expansion valve with a computerized controller of his own design. Some unusual factors inuence refrigeration design for the moon. Heat removed from living spaces by the air conditioning cant be transferred to ambient atmosphere as it is here on In addition to refrigeration and airconditioning equipment, Sun Danze is a principal supplier of photovoltaic arrays for NASA projects in space. earth, because on the moon there is, practically speaking, no atmosphere. Some of the removed heat is used for heating water, and the rest is radiated from the condenser into deep space. The demands on mechanical systems are extreme. Because there is no atmos phere, the surface temperature at lunar noon is over 250F. The lunar day is as long as 14 earth days. With the night also two weeks long, efciency is critical. Returning to the moon is not simply a matter of scientic curiosity, although that will play a part probably for centuries to come. Discoveries in recent years have shown that it is likely to be nancially feasible to mine the moon for Helium 3 a safe, efcient, and nonpolluting source of energy for the earth.

MOTION CONTROLS Ingersoll Rand and Danfoss Join Forces for Fourth Utility Control T he result of a joint development project between Ingersoll Rand Air Solutions and Danfoss Motion North America Controls is an advanced compressed air system that provides constant pressure control for plant ef ciency and energy savings. Due to the success of the project, it has become a model for agreements in South America, India, and Asia. Industries of all types rely on compressed air systems to power operations such as processing, material transfer, instrumentation, tools, damper actuation and thermo static control. Because of the prevalence of compressed air in plants, manufacturers commonly refer to it as the fourth utility, after electricity, natural gas, and water. Yet compressed air is often the most poorly controlled utility in a facility. The solution developed by Ingersoll Rand and Danfoss combines a highly efcient rotary screw compressor linked to variable frequency drive VFD technology. In the United States compressed air systems account for about 1. 4 billion dollars per year in energy cost expenditures, according to the U. S. Department of Energy DOE. In a common application, compressed air can account for 10 to 20 percent of a manufacturing facilitys energy bill. In North America and other parts of the world there has been a big push for industrial facilities to cut down on energy costs, says Keith Waldo, product engineering team leader for Ingersoll Rands Medium Industrial Systems. Because of the demand from our customers we decided to integrate VFD technology into Ingersoll Rands already extremely efcient system. For mediumsized compressor applications, Ingersoll Rand offers the IR 5000 VFD, manufactured by Danfoss, as an addon for new installation or retrot. In an average medium compressor system with imprecise pressure control, header pressure can uc Ingersoll Rand and Danfoss engineering teams have worked together to design a system that precisely matches the compressors output to the capacity that a plants air system needs. 2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=13http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=13Vol. 1 Issue 511Danfoss Dependable. tuate by about 20 PSI. For each PSI point increase there can be an addi tional 0. 5 to 1. 5 percent cost in energy expenditure. The VFDcontrolled com pressor can maintain pressure in a typi cal system 1 PSI . In traditional systems, the air compressor often runs at higher pressure than is required during its operation cycle. The VFD controlled compressor eliminates the need to operate the compressor at a higher pressure. And instead of relying on inefcient values to regulate the compressor, the VFO matches the com pressors speed to precisely match the demand for air. These features can reduce energy consumption by up to 35 percent. For example, a 100 HP machine operating at 70 load that costs a plant approximately 35, 000 on 6000 hours operation could decrease to 24, 000. Many industrial facilities that invest in the IR 5000 VFD compressor system report investment payback within a year, according to Waldo. The savings amount depends on the application, reg ulations, and incentives, but overall cost reduction is signicant in most cases. Ingersoll Rand and Danfoss engineering teams have worked together to design a system that precisely matches the compressors output to the capacity that a plants air system needs. Together we optimized a control approach which drew upon the best functions of both the IR and Danfoss controllers, says Danfoss application engineer Bruce Widell. The controller was able to pickup the xed speed and PID closed loop regulation tasks, which minimized any modications to the proven IR Intellisys controller. The VFD option package involves an Ingersoll Rand mediumsized rotary screw compressor, from 50 to 500 HP, linked to the IR 5000 branded variable frequency drive using Danfoss drive technology. The system not only reduces wasted energy dramatically, but also stabilizes pressure in the plant so that processes run more smoothly and reliably. Rotary screw process Ingersoll Rands rotary screw compres sor uses a simple, efcient process that can operate with much lower tempera tures than a reciprocating compressor. The lower temperature enables the rotary screw air compressor to operate in a fully loaded continuous cycle for 24 hours per day, year round. The compressor uses a positive displacement process in which air enters a sealed chamber and is trapped between two contrarotating rotors. Rotation traps air between the lobes on the rotors. Rotation continues as the lobes on one rotor roll into grooves on the other and the space occupied by the air is reduced to increase pressure. Compression con tinues until the air is discharged on contactcooled machines mixture of compressed air and injected water or oil leaves the air end and passes into a separator where the liquid is removed from the compressed air. The air is then separated from excess moisture and cooled. The VFD varies the speed of the main drive motor so that the motors speed matches compressor demand. The system has a PID controller for constant pressure control. A digital panel inter face displays information on frequency, power, RPM, current, hours run, and torque for easy monitoring. The VFD equipped system also allows for soft start of the motor, which reduces stress on the system components and increases system reliability. A DOE survey found that 35 percent of plant representatives report unsched uled shutdowns of their compressed air systems within a 12month period. Sixty percent of these establishments had unscheduled shutdowns of two days or more. VFD technology reduces compressor cycling, making the compressed air system more reli able and increasing plant productiv ity.

MOTION CONTROLS In 1847, after arriving in London, Ontario, from Ireland, John Kinder Labatt estab lished The Labatt Brewery, now one of the oldest and most famous Canadian compa nies. In the 1850s, The Great Western Railway allowed the company to ourish outside London and explore new markets in Ontario and Quebec. Today Labatt beverages, produced in eight breweries coast to coast, are well known around the world. Labatt prides itself on using leading edge technology in brewing and packaging. Recently, Labatt turned to engi neering rm Paton Controls in Sarnia to help make its water process more efcient in one of its breweries. The brewary uses water supplied from a well, which is pumped through a owme ter at a maximum rate of 40 literssecond. At this high rate the well could not replenish itself sufciently, therefore affecting the regional water table. Labatt sought another method. When John Bone, engineer for Paton Controls, approached Danfoss inquiring about a drive, his rst question was, How often can a Danfoss drive be switched off and on Patons original design was based on manual monitoring of the depth indicator and the drive located in the pump room would be switched off as the well water level decreased. Labatt Brewery Steps Up Control Danfoss VLT adjustable frequency drives2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=15http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=15Vol. 1 Issue 513Danfoss Dependable. Paul Lamarre of Danfoss in Canada rose to the challenge with Danfoss VLT adjustable frequency drive technology equipped with multiple analog inputs and the Sleep Mode Feature. This eliminated the need for manual monitoring. In this application, the owmeter sends a 420m A signal to a drive that controls the pump motor speed through a builtin PID processor to maintain a ow setpoint of 24 literssecond. It requires the system to consistently adjust to water levels. The VLT receives 010 volt DC analog input signal from the pressure transmit ter to monitor the water depth and 4 20m A signals from the owmeter. The Danfoss Drive controls the entire pumping system, eliminating the need for manual monitoring of water levels. It permits up to three analog inputs to interact with each other, thereby allowing the owmeter and pressure transmitters to be connected to two separate inputs simultaneously and interact with each other. Under normal water level conditions the 24 literssecond is preprogrammed as the set point. The drive is pro grammed to reduce the set point as the as the 0 10 VDC depth indicator signal indicates a water surface level of less than 5 meters above the pump. The Sleep Mode feature is utilized to adjust to low water levels. For instance, to maintain 24 literssecond the drive would run the pump at 49Hz. When the water level in the well is above 5 meters, the pressure transmitter will send a 10VDC signal to the drive, but as the water level falls below 5 meters the signal will decrease. As the depth signal decreases, it reduces the motor speed until the sleep frequency of 42 Hz is reached. When installed, the PID control was able to maintain a well water level of not less than 5 meters by adjusting the frequency and by pump ing at a reduced rate of 21 literssecond, which stabilizes the level of the aquifer. While in Sleep Mode, the Drive turns the motor off at a preset Sleep fre quency, and turns it on at a preset Wake Up frequency 45Hz. The drive monitors the analog inputs and calculates the appropriate frequency of the motor. When the calculated frequency matches the Wake Up frequency, the drive automatically starts the motor and runs the pump to maintain the set point. Today, Labatt reports that the pumping system runs awlessly. The standard Danfoss Drive with its builtin process control inputs and programming fea tures has eliminated human error. It allows easy monitoring of the water level and makes for efcient use of the well water so the brewing runs smoothly. Cheers Paton Controls, Engineering Firm in Sarnia.

AIRCONDITIONING REFRIGERATION International Solar Refrigeration Project Will Save Lives Solar Chill will allow Humanitarian organizations to transport lifesaving vaccines to previously unaccessable locations. N early 30 million children around the world have no access to immu nization, according to the World Health Organization WHO. As a result, nearly two million children worldwide die each year of vac cinepreventable illnesses. This medical crisis is due in part to the difculties of transporting vaccines to remote areas. In developing countries in the country side and villages theres no electricity at all, says a spokesperson for the United Nations Children Fund UNICEF. Electricity is essential to maintain the cold chain. Otherwise, by the time the vaccine reaches the child it is like water. Solar energy is helping to combat this problem. In 1999 an extraordinary international collaboration between industry and humanitarian and environ mental organizations was formed that has given rise to Solar Chill, a solarpowered refrigeration cabinet. The project provided a unique opportunity for organizations with different interests and resources to work together on a common desire to help save lives. The following organizations contributed to the Solar Chill project, which debuted at the 2002 World Summit on Sustainable Development in Johannesburg, South Africa Danfoss, GTz Proklima, Vestfrost, Danish Technical Institute, United Nations Environment Programme, United Nations Children Fund UNICEF, the World Health Organization and Greenpeace International. The refrigerator runs on a directcurrent Danfoss BD compres sor. It harnesses the suns energy to freeze an ice compartment that maintains the desired temperature, even at night. The unit does not require a battery and costs about twothirds of other solar technology. The compressor from Danfoss is quite advanced and can run at variable speeds to control the cool ing capacity, says Per Henrik Pedersen, project manager for Solar Chill at the Danish Technical Institute DTI. We can adapt the cooling capacity to match the suns power. Danfoss worked with DTI to install electronics that resolve the challenge of controlling the compressor speeds during uctuations in power. Solar Chill technology has undergone successful tests in a standard freezer and upright refrigerator and is ready for the eld test stage. The Solar Chill technology will undoubtedly save lives. Humanitarian organiza tions like UNICEF will be able to use the cabinet to haul vaccines across desserts, over mountains, and through other perilous terrain to save children from deadly diseases like polio and measlesdiseases easily prevented with the healthcare access that we take for granted in developed countries. 2007-07-09T17:02:13+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=18http://danfoss.ipapercms.dk/refrigerationandairconditioning/RA/Solutions/US/SolutionsVol152002/?Page=1816Vol. 5 Issue 1Danfoss Dependable.
