Energy saving using a VLT® drive is achieved even with a modest reduction in speed Where temperature is critical Industry facilities for the production of medicine or micro electronics require special precautions. The VLT® drives can meticulously control and maintain the correct temperature in the process under a variety of operating conditions, including continued operation during mains voltage fluctuations. 32012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=4http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=4VLT® solutions optimise cooling systems District cooling District cooling is becoming increasingly interesting due to the high demands for energy optimisation. District cooling is made by absorption and adsorption cooling from electricity production, heatpump systems or natural cooling from the sea or underground. VLT® drives can optimise the control of the system and help to increase the total energy saved. The larger the system, the greater power required – and VLT® drives go all the way. Stable cooling circuit • Efficiency increase of electronic expansion valves • Avoiding “flash gaz” due to lack of subcooling when fans are switching • Stable liquid level Lower noise level: • Lower speed at fan extremities • No switching and changing noise levels Less dirt in coils: • Lower Δt and higher compressor efficiency • Less maintenance costs 4 Pump Adding VLT® drives on pump applications in the refrigeration system will reduce the energy comsumption while increasing system performance. The Sleep Mode will prevent pumps running at low or no flow. The Dry Pump Protection and End of Curve Detection will protect the system in case of defective pumps or leaks.2012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=5http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=5Evaporator fan Reduced ice build-up and optimised evaporator temperature leads to lower energy consumption and higher system efficiency. The energy consumption is reduced by always matching capacity to the actual load. Condenser fan Optimal control leads to stabilised pressure in the condenser. This ensures better control of the pressure difference between evaporator and condenser and a better COP for the compressor. The control of airflow is matched to the actual need resulting in decreased audible noise and energy consumption. Compressor Variable speed control of a compressor offers the ability to match the cooling capacity to the actual need based on measurements in the refrigeration system. Costs are reduced both through energy savings when running at lower speed, but also through lower installation costs caused by optimisation of the refrigeration system and the compressor itself. Variable speed controlled also reduce the need for compressor packs because the individual compressor is adjusted to the actual need. The lifetime of the compressor is increased due to few starts and stops which cause mechanical wear and tear. 52012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=6http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=6The modular VLT® technology platform VLT® AutomationDrive, VLT® HVAC Drive and VLT® AQUA Drive are all built on the same modular platform allowing for highly customised drives mass produced, tested, and delivered from the factory.

I/O options General purpose I/O. Relay. Display options Danfoss Drives’ renowned removable Local Control Panel has an improved user interface. Choose between six built-in languages (including Chinese) or have it customised with your own. Two of the languages can be changed by the user. The info button makes the printed manual virtually redundant. Users have been involved throughout development to ensure optimum overall functionality of the drive. The user group has significantly influenced design and function of the Local Control Panel. The Automatic Motor Adaptation, the Quick Set-Up menu and the large graphic display make commissioning and operation a breeze. Choose numerical display, graphic display or no control panel. Hot plugable LCP The local control panel (LCP) can be plugged in or out during operation. Settings are easily transferred via the control panel from one drive to another or from a PC with MCT10 set-up software. The VLT® series local control panel was given the international iF design award in 2004. The panel was chosen from a total of 1,003 entries from 34 countries in the category “interface in communication”. Safety The new VLT® series can be ordered with safe stop functionality suitable for category 3 installations according to EN 954-1. This feature prevents the drive from starting unintentionally. Optional with Profisafe. 24 V supply 24 V supply keeps the VLT® drives’ control card "alive" in situations when the AC power supply is removed. 72012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=8http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=8Improved fan and pump operation User-friendly control, distributed intelligence and reduced power consumption are beneficial for fan applications. The capacity is always matched to the actual load. Lower installation cost VLT® drives are fitted with a built-in smart logic controller and auto tune PID controllers. They can control refrigeration system functions with fans, pumps and compressors. Valuable data points are saved. Extends system’s capacity When integrated into the cooling network, all the drives I/O points are available as remote I/O’s to extend the systems capacity. For example, temperature sensors (Pt1000/Ni1000) can be directly connected. Operational savings • Less dirt build-up on condenser • Load dependent capacity control • No need for separate starting equipment • No need for separate motor protection Applied cost benefits • Eliminate the need for starters, overloads, physical I/O • Reduce physical I/O by using the VLT® drive’s I/O to control fan • Reduced amount of refrigerant • Operate single fans as well as multiple parallel operating fans Resonance Monitoring By pressing a few buttons on the Local Control Panel the drive can be set to avoid frequency bands at which connected fans create resonances in the system. Intelligent functions The VLT® drives handle logical rules and input from sensors, real-time functionality, and time-related actions. This enables the drives to control a wide range of functions, including: • Weekend and working-day operations • Cascaded P-PI for temperature control • Multi-zone pressure control • Flow balancing Fan features • Smart Logic Controller • Auto tune PID controller • I/O points are available as remote I/O’s • Resonance Monitoring • Cascaded P-PI for temperature control • Different enclosures available • Flow balancing • AEO using Cos phi algorithm • Flying start • Improved Floating Head pressure • SW algorithm to detect abnormal overall input power • VLT® Pre-heat function Benefits – Lower installation cost – Valuable data points are saved – Easier set-up/commissioning – Extend the system’s capacity – Noise reduction – Resonance damping – Lower installation costs – Multi-zone control – IP20. IP 21, IP 55 and IP 66 – No external cooling or oversizing necessary – Upto extra 10% savings – Can control “free-wheeling” fan in both directions – Reduced power consumption – Protects the motor(s) from facing the negative effects of over/under voltage and phase unbalance – Eliminate anti-condensation heater 82012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=9http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=9Evaporator Pump Condenser Reduced ice build-up and optimised evaporator temperature leads to lower energy consumption and higher system efficiency. The energy consumption is reduced by always matching capacity to the actual load. VLT® drives offer a vast number of pump-specific features developed in cooperation with OEMs, contractors and manufacturers around the world. Sleep Mode In Sleep Mode the drive detects situations with low or no flow. Instead of continuous operation it boosts the system pressure and then stops to save energy. The drive starts automatically when the pressure falls below the lower set point. Monitors broken belt, dry pump and “end-of-curve” From the relation between current and speed, the VLT® drive reliably recognises “effortless” high speed – where the desired pressure is not reached despite of the speed, and indicates a broken belt, a dry pump or a major leak. The drive sets off an alarm, shuts off the pump, or performs another programmed action. First cost and down-time is reduced and equipment is protected. Optimal control leads to stabilised pressure in the condenser. This ensures better control of the pressure difference between evaporator and condenser and a better COP for the compressor. The control of airflow is matched to the actual need resulting in decreased audible noise and energy consumption. Pump features • Pump Cascade Controller • Sleep Mode • Dry Pump Protection • End of Curve • Flow compensation Benefits – Keep wear and tear on individual pumps at a minimum – Save energy – Protect the pump – Save energy – Protect the pump – Reduce energy consumption – Save energy Pump Cascade Controller The Pump Cascade Controller is the most sophisticated controller on the market. It distributes running hours evenly across all pumps, keeps wear and tear on individual pumps to a minimum and ensures that all pumps are in great shape. Auto tune PID controllers can control refrigeration system functions with fans, pumps and compressors. Valuable data points are saved. 92012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=10http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=10Improved compressor operation VLT® drives are designed to offer flexible, intelligent control of scroll, screw, piston and centrifugal compressors, making it even easier to optimise cooling capacity with constant temperature and pressure levels for typical compressor applications in refrigeration. Optimised pressure leading VLT® control leads to better COP (lowest condensing and highest evaporating temperature). Improved superheat control VLT® control ensures that all cooling media have evaporated. Reduced ice build-up Optimum evaporator temperature is achieved causing lower energy consumption to de-icing. Stabilised pressure Stabilised pressure in the condenser reduces the number of starts and increases lifetime. Replace a cascade with a single compressor VLT® drives provide same level of flexibility with one large compressor instead of a cascade of 2 or 3 smaller compressors. The VLT® drive operates all compressors at a far more refined range of speeds than normal. This includes even above nominal speed, meaning that one large compressor is enough. Set point in temperature VLT® drives calculate the actual room temperature from the pressure in the cooling media and refines compressor operation accordingly – without the need for additional software, sensors or controllers. The calculation is also applicable to the set point as well, so the desired temperature is set via the Local Control Panel – and not a pressure value. Fewer starts and stops A maximum number of start/stop cycles within a given period of time can be set via the Local Control Panel. Since start-up is the most critical part of compressor operation (all parts of the unit are under mechanical stress before the system is sufficiently lubricated) this extends compressor lifetime. Quick start-up To extend life even further, VLT® drives can open a bypass valve and let compressors start quickly without load. VLT® HVAC drive provides up to 130% break away torque and can give 110% torque for 60 seconds in normal operation. For 160% torque demand, the VLT® AutomationDrive can be applied. Features • High starting torque • Reduced current limit • Will run for as long as possible (running at current limit) • Maximum number of starts • Min. time between starts • Min. running time • Set-point in temperature • Quick start-up Benefits – No need for larger drive – Ensure functionality of cooling system – Protect the application – Extend the system’s capacity – Protect compressor – Reduce energy consumption – Easy operation – Protect compressor – Reduce energy consumption Operational savings • Power savings • Less wear and tear Applied cost benefits • Flexibility with few compressors • Less need for software, sensors and controllers 102012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=11http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=11Scroll The scroll and screw compressors are gaining market share in the refrigeration applications. The VLT® drives have dedicated refrigeration system functions to control these compressors. Screw Typically divided in oil-free screw compressors and oil lubricated screw compressors. Energy savings from adding a variable speed drive on the oil lubricated compressor will be twice the savings on the oil-free compressor. This is caused by the loss at no-load condition, which is much higher on the oil lubricated type. Further savings are achieved by optimised regulation of the pressure. Centrifugal These compressors are used in industrial applications with a large cooling demand. The VLT® drives can control the compressor as well as being integrated in the control system for the plant. Piston The piston compressor has the highest market share in refrigeration applications. The VLT® drives can improve performance on piston compressors. 112012-08-06T16:01:12+02:00http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=12http://danfoss.ipapercms.dk/Drives/DD/Global/SalesPromotion/Brochures/SBABrochures/02VLTRefrigeration/?Page=12VLT® drives in the biggest indoor ski resort in the world The biggest indoor ski resort in the world, “Ski Dubai” opened its doors in September last year.
