1. A heat pump apparatus comprising:
an evaporator that evaporates a refrigerant;
an electrochemical compressor that compresses the refrigerant evaporated in the evaporator by use of an electrochemically active, non-condensable gas;
a condenser that condenses the refrigerant compressed by the electrochemical compressor;
a refrigerant delivery path for delivering the refrigerant from the condenser to the evaporator; and
a non-condensable gas return path provided separately from the refrigerant delivery path, the non-condensable gas return path being configured to communicate a discharge-side high-pressure space of the electrochemical compressor with a suction-side low-pressure space of the electrochemical compressor so as to return the non-condensable gas from the high-pressure space to the low-pressure space.
