Abstract

A changeover heating/cooling heat pump has four solenoid valves (1-4) to change between modes. One (3) of them, controlling the delivery of refrigerant from a water/refrigerant heat exchanger (6) provides a pressure limiting function to avoid overpressures at the suction side of the compressor (5). One (17) or two (8,13) refrigerant expansion devices are used in the case of a single, electronically controlled device (17), the temperature control signal is derived from the outlet of whichever of the heat-exchangers (6, 9) is currently rejecting heat.
