ABSTRACT:
A heat pump apparatus comprising: a heat pump circuit composed of an external combustion engine, a radiator through which a first medium heated by a first heat exchanger of said external combustion engine flows and a cooler through which a second medium cooled by a second heat exchanger of said external combustion engine flows; a motor for supplementing a motive power to said external combustion engine; a brake for braking said external combustion engine; a detector for detecting a heating load; and a controller for calculating a motive power necessary for said external combustion engine based on the difference between a value detected by said detector and a preset value previously set, and for controlling said motor to move when the calculated motive power is larger than a self-output of said external combustion engine.
