Document Type and Number:
WIPO Patent Application WO/2019/007150
Kind Code:
A1
Abstract:
A method for controlling a heat pump system (1; 10). The heat pump (1; 10) system comprises a compressor (2; 20) for compressing a working fluid (3; 30) of the heat pump system (1; 10) and an electric motor (4; 40) for providing an output torque for driving the compressor (2; 20). The method comprises the steps of recovering heat emitted from the electric motor (4; 40) by heating the working fluid (3; 30),providing a first control mode and a second control mode for the electric motor (4; 40), and controlling the electrical motor (4; 40) in a way creating higher heat losses of the electric motor (4; 40) for a given output torque of the electric motor (4; 40) in the second control mode than in the first control mode.
