Heat pump operating method, involves alternatively switching compressor from compressed condition to idle condition, and synchronizing refrigerant overheating control with switching of compressor from compressed condition to idle condition

摘要

The method involves arranging an evaporator, a compressor and a condenser in a successive manner. The compressor is alternatively switched between a compressed condition, in which a refrigerant is compressed, and an idle condition, in which the refrigerant is not compressed. A refrigerant overheating control is synchronized with the switching of the compressor from the compressed condition to the idle condition. An independent claim is also included for a heat pump including an over heating control unit.
