Abstract (en)

[origin: EP3598014A1] Provided is a technique that allows a so-called hybrid heat pump system including, as a compressor for a refrigerant circuit, an engine-driven compressor and an electric-motor-driven compressor to achieve a rational structure with redundancy. According to this technique, the hybrid heat pump system includes: an operation control unit A including an engine control unit 25 controlling operation of an engine 21 and an electric-motor control unit 35 controlling operation of an electric motor 31, which are individually provided; and a power source unit B converting commercial electric power into operating electric power and supplying the operating electric power to the operation control unit A, the power source unit B including an engine-side power source unit 23 supplying the operating electric power to the engine control unit 25 and an electric-motor-side power source unit 33 supplying the operating electric power to the electric-motor control unit 35, which are individually provided.
