Heat Pump Valve Unit

The heat pump valve unit is comprised of various heat pump components that distributes refrigerant to the heat pump system. The heat pump valve unit consists of the following components.

• vapor injection heat pump heating liquid gas separator (HGLS) valve
• vapor injection heat pump cooling liquid gas separator (CLGS) valve
• vapor injection heat pump cooling electronic expansion valve (CEXV)
• vapor injection heat pump heating electronic expansion valve (HEXV)
• vapor injection heat pump battery chiller electronic expansion valve (BCEXV)
• vapor injection heat pump low side refrigerant shut off valve
• pressure and temperature sensor A
• water cooled condenser (WCC)

These components are serviced as an assembly with the heat pump valve unit.
