METHOD OF OPERATING A HEAT PUMP

摘要

A method of operating a heat pump having an inside heat exchanger, an outside heat exchanger, a compressor, and valves that control the circulation of a refrigerant such that in one operating mode the inside heat exchanger operates as an evaporator while in the other operating mode it operates as a condenser. When switching from one operating mode to the other operating mode first the compressor is stopped, then the inside heat exchanger and the outside heat exchanger are directly connected via the valves until pressure is equal in both of the heat exchangers. Subsequently the valves are moved back into the positions appropriate for the desired operating mode, and the compressor is restarted.

1. A method of operating a heat pump having:
an inside heat exchanger; an outside heat exchanger; a compressor; and valves that control the circulation of a refrigerant such that in one operating mode the inside heat exchanger operates as an evaporator while in the other operating mode it operates as a condenser, the method comprising the steps when switching from one operating mode to the other operating mode of sequentially: stopping the compressor; directly connecting the inside heat exchanger and the outside heat exchanger via the valves until pressure is equal in both of the heat exchangers; moving the valves into the positions appropriate for the desired operating mode; and restarting the compressor.
