  • Page 21: Product Design

    PRODUCT DESIGN This section gives a basic description of cooling unit opera- tion, its various components and their basic operation. Ensure your system is properly sized for heat gain and loss according to methods of the Air Conditioning Contractors Association (ACCA) or equivalent. CONDENSING UNIT These units are designed for free air discharge.
  • Page 22 PRODUCT DESIGN The coils are designed for upflow, counterflow or horizontal application, using two-speed direct drive motors on the CACF/CAPF/CHPX models and BPM (Brushless Permanent Magnet) or ECM motors on the MBE models. The ARUF is a multi-position air handler (upflow/horizontal or downflow) and is equipped with a flowrator for cooling and heat pump applications.

  • Page 23: System Operation

    SYSTEM OPERATION COOLING The refrigerant used in the system is R-22. It is a clear, colorless, non-toxic, non-irritating, and non-explosive liquid. The chemical formula is CHCLF atmospheric pressure is -41.4°F. A few of the important principles that make the refrigeration cycle possible are: heat always flows from a warmer to a cooler body, under lower pressure a refrigerant will absorb heat and vaporize at a low temperature, the vapors may be...

  • Page 25 SYSTEM OPERATION EXPANSION VALVE/CHECK VALVE ASSEMBLY EXPANSION VALVE/CHECK VALVE ASSEMBLY IN COOLING OPERATION IN HEATING OPERATION ® Most expansion valves used in current Amana Brand Heat Pump products use an internally checked expansion valve. This type of expansion valve does not require an external check valve as shown above. However, the principle of operation is the same.
  • Page 26 SYSTEM OPERATION COOLING CYCLE - CONDENSING UNIT Indoor Outdoor Coil Coil Thermostatic Expansion Valve In the cooling mode, the orifice is pushed into its seat, forcing refrigerant to flow through the metered hole in the center of the orifice.
  • Page 27 SYSTEM OPERATION AFE18-60A CONTROL BOARD DESCRIPTION The AFE18 control is designed for use in heat pump applica- tions where the indoor coil is located above/downstream of a gas or fossil fuel furnace. It will operate with single and two stage heat pumps and single and two stage furnaces. The AFE18 control will turn the heat pump unit off when the furnace is turned on.
