1 MAKING MODERN LIVING POSSIBLE REFRIGERATION & AIR CONDITIONING DIVISION ADAP-KOOL Drive A New Drive for Energy Efficiency AKD 102

2 2 The AKD 102 comes with a common user interface and covers power ratings of HP.

3 A New Drive for Energy Efficiency Easy to set up, easy to use Designed specially for ease of use by Danfoss Food Retail customers, the AKD 102 drive is highly energy efficient, both a financially and environmentally responsible choice. It s a proven fact that variable speed drives save significant energy by providing better capacity control. As utility rates escalate, the return on investment in drives has never been better. There has long been a need for a drive specifically dedicated to refrigeration and HVAC applications and designed for food retail facilities. Working with food retail professionals, Danfoss has designed the AKD 102 drive series to speak their language. This drive sets a new standard in simplicity for setup, commissioning, and troubleshooting. Two standout features of the AKD 102 are: A Setup Wizard that makes the installer s work a structured, comfortable process using familiar refrigeration terms; A Built-in Manual that is context sensitive, easily accessed with a single keypad stroke. The setup wizard covers the three most common applications in supermarket refrigeration: Compressors Condensers Pumps All drives in the AKD 102 series, from 1.5 to 125 HP, have the same setup wizard, display, logical menu structure, and built-in manual, so that technicians use the identical methods for setup, commissioning, adjustment, and troubleshooting throughout the horsepower range. Built for your bottom line Using variable speed drives with your energy management system provides new possibilities for energy savings in any facility. 3

4 Reducing energy costs Fan & Pump Control Pumps With their substantial reduction in refrigerant charge, secondary refrigeration systems are seeing increasing application. These systems require pumps to circulate the secondary fluid. A variable speed pump maintains constant fluid pressure as system load changes, assuring maximum system efficiency. If the speed of a fan or pump is reduced by 50%, power consumption is reduced by 87.5%. An AKD 102 controlling the pump in a secondary refrigeration system with or without connection to an EMS has multiple safety and energy saving functions, including: No-flow detection An energy-saving sleep mode End-of-curve protection Energy savings with a AKD 102 variable speed strategy are indeed substantial. Power Power is consumed by a fan or pump according to the Affinity Law. This principle of physics relates power consumed to shaft speed. Power consumed is proportional to shaft speed cubed Capacity VFD Speed VFD Power

The result is that or heating is needed, only a fraction of matched to the load, resulting in a much of the time the condenser is full speed is required. higher COP. running with excess capacity, wasting energy. In contrast, a variable speed strategy yields continuously variable capacity, and fans deliver exactly the capacity needed all the time, with no wasted capacity and no wasted energy. HVAC An AKD 102 drive varies the speed to meet setpoints most efficiently. When no heating or cooling is called for, the drive provides the minimum speed sufficient for comfortable airflow in the building. Compressors With the AKD 102, there is no wasted capacity and no wasted energy. Controlling noise Fixed speed condenser fans starting at full speed and stopping abruptly can be a concern to zoning authorities. With an AKD 102 drive programmed to gradually bring fans from minimum speed to the required capacity, there is significantly less noise, often making costly architectural modifications unnecessary.
