Heat Pump, HVAC System and Compressor Device

A heat pump for use in an HVAC system, which comprises, as part of a working circuit of the heat pump, at least one compressor device (1) for compressing a working medium of the working circuit,

• wherein the compressor device (1) in turn comprises:
• an electric motor (32) for providing a mechanical movement for compressing the working medium;
• an inverter (31) which supplies the electric motor (32) with alternating current;
• a rectifier (11) which supplies the inverter (31) with direct current, wherein the rectifier (11) can be connected to an alternating current source for supplying energy to the compressor device (1);
• and
• a monitoring device (12) for monitoring an operating state of the electric motor (32), which monitoring device comprises at least one measuring means (122, 123) for detecting an operating variable of the compressor device (1) and an evaluation means (121) for evaluating the detected operating variable;
• wherein the electric motor (32) and the inverter (31), which supplies said electric motor with alternating current, are integrated jointly in a DC compressor unit (30) of the compressor device (1), which DC compressor unit is coupled via a direct current interface (20) to an electronics unit (10) of the compressor device (1) which is separated from said DC compressor unit and in which in turn the rectifier (11) and the monitoring device (12) are integrated jointly.
