At the same time, demands for envi ronmental responsibility and for compliance with ISO standards are boosting incentives for efciency improvements. Despite lowered factory outputs due to the economys downturn, the Bureau of Labor Statistics reports that manufacturing productivity in the United States grew 4. 5 percent last year. American companies, which have long been leaders in efciency, are adjusting to the times and nding ways to optimize their operations. Paradigms, technology tools and processes are only part of the equa tion to increasing efciency. Making more and better products with fewer resources involves building a culture that works toward continual process improvements. LEAN THINKING The greatest revolutions in manufac turing efciency have come from the automobile industry, starting with Henry Fords mass production methods. The automobile industry also led to a paradigm shift called Lean Thinking. Lean production took hold in American companies in the 1990s and now pervades much of the manu facturing world. This model became popular thanks to a study at the Massachusetts Institute of Technology that looked at the move from mass production to techniques involving Japanese auto making concepts of using fewer resources, from manpower to material and oor space, to capital, while achieving output goals. As described in the book The Machine That Changed the World, the lean model stresses an evolving process of change and adaptation rather than a technologydriven operation. Some key lean principles are rst time perfect quality, minimizing waste by diminishing activities that do not add value, continuous improvement, exibility, and building longterm supplier relationships. Rather than creating a bigger, more complex enterprise, operations focus on inno vation and efciency. This goes hand inhand with a commitment to quality, making things right the rst time. Danfoss has been implementing lean production principles in its facto ries as part of its focus on industry leadership. In Canada, for example, Danfoss in Calgary, Alberta, has introduced lean manufacturing to their production of ZCP Zone Control Panels. Due to unprecedented demand from the users Industry today is in the midst of dramatic change. Rapid exchange of products and information has ushered in an age in which market demands are global and production costs must decrease while quality remains high. 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=5http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=5Vol. 2 Issue23Danfoss Dependable. and OEMs, it was necessary to nd ways to produce more panels without adding signicant resources. A lean production engineer analyzed the processes and workow and imple mented appropriate changes. Although the lean process is in its infancy, it has already enabled the Calgary facility to double its production. Bill Willemsen, Vice President of Marketing for the Heating Division, explains, We sell the ZCP as a product that reduces eld labor, eliminates parasitic losses, minimizes handling, and eliminates quality problems on the job site. These are all major components of a lean approach and now our produc tion as well as our customers are beneting from lean thinking At Danfosss facility in Baltimore, the lean approach is part of an overall focus on quality and competitiveness for production of refrigeration and airconditioning components. By using the lean principles and cus tomizing them for our own business, we can achieve growth and satisfy customers at the same time, says Claus Peitersen, Vice President of Operations. Lean thinking is not only an internal process, it also involves working with external suppliers and partners to apply principles in efciency. COOL EFFICIENCY In refrigeration, efciency changes have been a quiet revolution that has changed the industry. Manufacturers have developed their products to meet increasing efciency demands of household, industrial, and commercial refrigeration. Advances in commercial and trans portation refrigeration rst had impact on industries such as brewing, meatpacking, and food processing. Other industries also have changed due to new cooling technologies, from iron production and oil reneries to metalworking, textile, and munitions factories. Cooling and humidity con trol are used in various parts of the industrial process, including control ling temperature of machinery or materials. Efciency improvements brought on by new refrigerants, electromechanical innovations, compressor developments and computerized control systems also have had an enormous impact on food retailers. To keep up with demands for food centers within superstores, refrigeration manufactur ers have designed new lines of cabi nets, display cases and racks. At the same time, equipment must make the most efcient use of energy, the food retailers biggest expense. CULTURE OF IMPROVEMENT From industrial processes to the food chain, to water treatment and indoor comfort control, efciency is essential in all aspects of business activity. Finding ways to boost efciency is critical to manufacturing processes, the quality of products, and the envi ronment. It requires not only valid methods for efcient production but also an overall business culture that values constant and consistent improvement. 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=6http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=6Vol. 2 Issue24Danfoss Dependable. Diesel engines are used in a wide variety of applica tions worldwide, including heavy and mediumduty trucks, stationary power units, industrial and marine equipment, and construction, mining, and agricultural machines. There are principally two types of diesel engine con trol mechanical and electrical. Mechanically controlled engines are the foundation of diesel engine technology. But with mechanical engines, injection timing and injection pressure are set and cannot adjust for chang ing conditions. Customer demands for better efciency and greater functionality combined with environmental regulations for emissions control, drive development of electrical engine technology. Electronically governed engines can increase performance by using sensing devices to moni tor the performance of the engines fuel system. Using temperature and pressure sensors, an operator can also diagnose system performance to help prevent failures. Sensors are often installed to monitor intake or exhaust air pressure, oil pressures for safety or preven tative maintenance, and even fuel delivery pressures. This information is critical in determining whether or not the engine is burning fuel efciently, and in manag ing the schedule for preventive maintenance it is active feedback for the electronic control decision tree. Knowing the internal block pressures and temperatures in an electrically controlled engine can provide valu able insight to understanding and managing potentially dangerous failure modes. A Leader in Diesel Technology Cummins Inc. , based in Columbus, Indiana, is a global leader in diesel technology. Cummins designs and man ufactures diesel engines from 55 to 3, 500 horsepower. Danfoss works closely with the Cummins sensor design group and with various Cummins factories around the world to provide pressure and temperature sensors that meet exacting performance criteria of these high horse power engines for robust design and high performance. Components used on Cummins diesel engines undergo a rigorous testing process. Danfoss provides Cummins with its MBS series pressure transmitters with modied enclosure. Transmitter design also includes a tailored pressure port and customized electronics to meet appli cation requirements. During the highly accelerated life tests, the Danfoss sensors are put into a test chamber that cycles through high and low temperature, pressure pulsations and high vibration to ensure they will withstand the rugged Providing Power Around the World DDiieesseell EEnnggiinneess From the Bradley Fighting Vehicle made famous during Desert Storm to the generator set providing backup power to our hospitals, diesel engines are designed to meet demands for efcient and reliable heavyduty power with high performance. 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=7http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=75Danfoss Dependable.

The company supplies engines throughout the world, with parts available at ports of call worldwide. 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=8http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=86Danfoss Dependable. Vol. 2 Issue2 W hen global beverage manu facturer Coca Cola announced an initiative to optimize their vending machines in order to achieve a 40 percent reduc tion in energy, it raised the bar for vending equipment suppliers. In general, vending machine compres sors have considerable excess capacity during most of their run time. A high capacity compressor is required only during pulldown which is 12 percent of the cycle. This is the time it takes to fully chill the products after they are loaded into the machine in order to bring the beverages to sales temperature as quickly as possible. Looking at the overall operating cycle, there are tremendous opportu nities for saving energy during the 88 percent of the cycle when the system need not work so hard when it is only called upon to maintain the target temperature. Because of its expertise in appliance compressors and its application knowledge, Danfoss was the natural supplier to take on this challenge. Danfoss has a long history of involve ment in energy saving projects with the worlds leading manufacturers of commercial and household cooling cabinets. At the Danfoss laboratory facilities in Monterrey, Mexico, tests were performed using a cola vending machine to compare the incumbent compressor with a Danfoss compres sor. Using advanced technology, the Danfoss NF series hermetic compres sor used in the test is robust, quieter in operation, and more energy efcient. in search of ENERGY2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=9http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=9Vol. 2 Issue27Danfoss Dependable. Testing was performed in accordance with ANSIASHRAE 32. 11997 Method of testing for rating bottled and canned beverage vending machines at 902F, 655 RH. The machine was loaded with 768 Coca Cola cans. Measurements of power consumption, pulldown time, and average can tem perature were taken. Test results were astounding. Using the new energyoptimized Danfoss NF compressor, energy consumption was reduced by 25 percent. Traditionally, no expansion valve is used in vending machine systems. Rather, refrigerant is metered through a simple capillary tube. But in the second phase of testing, further ef ciencies were achieved by applying a thermostatic expansion valve TEV. Thermostatic expansion valves maxi mize evaporator efciency, helping to reduce the pulldown time. The second test compared a system with a TEV to one with a capillary tube under varying conditions of ambi ent temperature and relative humidity to analyze performance and energy consumption during initial pulldown time and during stabilized operation. Test data revealed the expansion valve system was, on average, 20 more efcient than one with a capillary tube. Systems Approach The nal phase of testing combined a TEV with a smaller, high efciency compressor. The combination yielded a 36 percent improvement in efciency, while still meeting the objectives established by Coca Cola. Signicant improvements like these are attainable by combining the right system strategies and evaluating com plete systems rather than individual components of a system. Looking at the system as a whole is crucial in optimizing performance and energy. Danfoss is a manufacturer of both controls and compressors, which enables us to have a system perspec tive that results in unique solutions to help our customers achieve their objectives, says John Galyen, Vice President of OEM Sales Marketing for Danfoss Air Conditioning and Refrigeration. Aiming for Even Higher Standards Along with the objective of reducing energy consumption, Coca Cola also announced an initiative to reduce the environmental impact of their cooling equipment over time, based on the Kyoto Protocol. The soft drink giant stated in a press release that they will no longer purchase new colddrink equipment using HFCs wherever cost efcient alternatives are commercially available. This is another challenge Danfoss has embraced. With our extensive research into alternative refrigerants, we are making the solu tion to this challenge a reality. An energyoptimized NF series compressor helps achieve efciency in vending applications. in vending machines Y EFFICIENCY 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=10http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=108Danfoss Dependable. Vol. 2 Issue2 L ow margin. Thats one of the rst concerns a busi ness manager has about supermarket operation. Supermarket prot margins are among the lowest in retail any reduction in xed expenses has an immediate effect on the bottom line. One of the largest costs in oper ating todays food stores is energypower for lighting, heating, cooling, and refrigeration. Twentyve years ago, Danfoss started supplying electronic controls to the supermarket industry, beginning a stream of innovative solutions that improve mechanical and energy efciency and improve food storage and shopping environ ments. Electronic controls have made possible substantial savings in lighting cost by automatically reducing lights during hours when few customers are shopping. Store tem perature and humidity are controlled so that shoppers are always comfortable without excess heating or cooling which can adversely affect the greatest energy load, the stores refrigeration. Refrigeration in a supermarket is an interesting and oner ous problem for the energy engineer because the solution requires both theoretical and practical knowledge of ther modynamics. To begin with, in order to keep food stored at healthful temperatures, heat must constantly be removed. But remove just a bit too much heat, and there are costly results Food freezes slowly and must be discarded, which one learns the rst time he freezes lettuce or any other kind of produce by mistake. Frozen meat slowly thaws to a condition where it spoils very rapidly. Frozen foods can be kept colder than necessary, but the cost of doing so is needlessly high. At the other end of the thermometric scale, fresh foods not kept cold enough often dont stay fresh long enough to sell. And frozen foods that thaw in the store are a total loss. Software algorithms in the controller exactly match the superheat to the load in the case in order to most efciently regulate the ow of refrig erant through the valve. That means that no overcooling takes place as with a purely mechanical system. Impact Bottom Line for Supermarket Chains2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=11http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=11Vol. 2 Issue29Danfoss Dependable. 9Danfoss Dependable. STRESSED REFRIGERATION Complicating the refrigeration prob lem is the environment in which cool ing takes place. A supermarket is not a carefully controlled laboratory, but a working environment where cases are constantly stocked to keep them full and customers are constantly opening case doors, admitting warm air to the refrigerated interior. Most of the stores cases, though, do not have doors, and every time a hand enters the cold zone, heat enters with it. All of these activities put heat stress on the refrigeration system. Before electronic controls came along, simple thermostats were used to open and close valves that delivered liquid refrigerant to the xtures in a store. At the xture another valve a ther mostatic expansion valve, or TEV, again activated by temperature, meters the refrigerant into a heat absorbing evaporator. Heat from the case is carried away with the refrigerant changed now into a gas back to the compressors in the machine room, and from there it is pumped to a condenser where it changes state to liquid so that the whole process can occur again. This system is called liquid side control because the ow of liquid through the expansion valve in turn controls the refrigeration process. Thermostatic expansion valves TEVs have to be set for a superheat that is based on the load capacity of the indi vidual xture. But cases and cooler boxes are not always stocked to the same level, and in fact as we have seen, staff and customer activity continuously change the load on the refrigeration system. So the setting is done to meet average conditions, and changing it is a tedious and inconvenient procedure. DANFOSS SMART CASE CONTROLLER Smart Case Control uses solidstate sensors and an electronic controller in each case. An electronic expansion valve EEV supplies just enough liquid refrigerant to meet the load on a case. Software algorithms in the controller exactly match the superheat to the load in the case in order to most efciently regulate the ow of refrigerant through the valve. That means that no overcooling takes place as with a purely mechanical system. The secret is an adaptive superheat algorithm that resides in the AKC 164 Smart Case Controller. It continuously changes the superheat in response to load changes. Put warm food into the case, and within six seconds the superheat is changed to match the new load. Liquid side adaptive superheat control has shown savings of more than 9 percent in tests audited by public util ity companies. Supermarket chain owners have received utility rebates based on these savings, in addition to the direct reduction of their utility bills. Store operators using adaptive liquid side control reap additional signi cant savings benets because they achieve a much lower head pressure, the pressure the system has to run to keep refrigerant moving in the system. Savings here are directly proportional to saved energy expense. Other benets of case control include a much cheaper installation, since much less cable and electrical labor are required in a case control store fewer components on the refrigeration machinery, reducing initial cost of equipment fewer product losses because of the builtin alarms and easier troubleshooting on site and off. A host of variables affect performance of a food retailers refrigeration equip ment. Sophisticated Danfoss control algorithms meet the challenge of maintaining peak efciency under any conditions. 2007-07-09T17:31:23+02:00http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=12http://danfoss.ipapercms.dk/refrigerationandairconditioning/ra/solutions/us/solutionsvol222003/?Page=1210Danfoss Dependable. Vol. 2 Issue2 I n the quest to create more efcient engines, transportation industries have been looking to fuel cell technology, which is two to three times more efcient than combustion engines and requires no moving parts. Fuel cells generate power by combining hydrogen fuel with atmospheric oxygen to elec trochemically produce electricity, water, and heat. Unlike battery power sources, fuel cells continue to produce power as long as fuel is provided, and can be used in virtually any application requiring electrical power, with no harmful emis sions. Taking part in the development of this new energy source, Danfoss has, in coop eration with Shell Hydrogen, UK catalyst manufacturer Johnson Matthey, and Mitsubishi, established a new venture company focused on fuel cell technology. An investment of 5 million to form Conduit Ventures, based in London, creates the rst venture company in the world to focus solely on fuel cell tech nology, though there are many companies working worldwide with it. Danfoss continually looks for alternative technologies in order to provide its customers with complete control solutions. We strongly believe that fuel cells and related hydrogen technologies will become the power systems of choice across multiple applications in the future, says Danfoss CEO Jorgen M. Clausen. FFuueell CCeellllis the Wave of the Future The U. S. National Committee of the International Institute of Refriger ation will host its 21st International Congress of Refrigeration ICR2003 in Washington, DC, from August 17 22, 2003.

To create a clean and efcient system for washing tomatoes, Californiabased West Coast Tomato turned to Bellato Engineering, which specializes in tomato plant operations. Bellato was looking for an efcient way to get the tomatoes cleaned and ready for pro cessing. It was a perfect t for the innovative water hydraulic system developed by Danfoss called Nessie. Nessie provides an alternative to traditional oil hydraulics by using water as a uid medium for power packs, pumps, valves, motors, cylinders, and accessories. Although Danfoss did not invent water hydraulics, it has made developments in the technology that have brought it back into use after nearly a century in which oil hydraulic systems have been the norm. Every year West Coast harvests many tons of green tomatoes. Cleaning the veg etables is an important and timesensitive part of the process, and Nessie water hydraulics technology is suited for this application because its resistant to corrosion, doesnt cause product contamination, and there are no pollution risks as there are with traditional oil hydraulics. Energy and uid costs are reduced as well. Water Hydraulics systems are safer than electric motors, which are made of mild steel or aluminum, making them prone to corrosion. In such a wet envi ronment, the service life of electronic components decreases. In the case of West Coast Tomatoes, water hydraulics is a solution to contamination issues acci dents in the cleaning process are costly and can damage a lot of produce. Once the tomatoes are harvested from the farms, theyre stored in massive one to threethousandgallon tanks. In order to get the tomatoes out of the tanks without damaging them, the tanks are lled with more water until the tomatoes rise to the top and oat out. Nessie hydraulics are used in the machinery that lls and oods the tanks, including the motor for the industrial tap, which is swung over the lorry, and the swing actuator that moves the tap 180 degrees over the tanks. After the tomatoes are ooded from the giant tubs into a big stainless tub, they go through a cleaning and disinfecting process. The cleaning system is like a river sixty feet wide and four feet deep in which the tomatoes are pushed along as the debris oats to the bottom. Nessie hydraulics run all functions of this system, including a conveyor. Also, a water hydraulic cylinder operates the gate valve, controlling the ow of tomatoes. Water hydraulics technology is specically designed to operate on uids with low viscosity, high vapor pressure and poor lubrication properties. In addition to the food industry, Nessie is also being applied in re ghting, automobile manufacturing, and mobile applications.
