Description
The Friedrich Air Conditioning 25018305 4-Way Reversing Valve Dunan is a heat pump refrigerant flow controller that reverses the flow of refrigerant between heating and cooling operation in HVAC systems. It is mounted in the refrigeration system and reverses the flow of refrigerant to allow the system to change between operating modes with temperature changes. This is used in residential and commercial air conditioning, where heat pump operation is desired for all season comfort. In the refrigeration system, the reversing valve reverses the operation mode, properly directs refrigerant, and helps operate the compressor and coils for both heating and cooling operation.
