Abstract

The invention discloses a heat pump unit, comprising: a compressor, the compressor has an exhaust port and an air return port; a reversing assembly, the reversing assembly has a first valve port to a fourth valve port; a first heat exchanger and a second heat exchanger Heater, the first end of the first heat exchanger is connected with the second valve port, the first end of the second heat exchanger is connected with the third valve port, and the first heat exchanger is connected with the second heat exchanger; heat recovery The heat recovery device includes a refrigerant flow path and a water flow path for mutual heat exchange, the first end of the refrigerant flow path is connected to the first valve port; the regulating valve, the first port of the regulating valve is connected to the exhaust port, and the second The port is connected to the first valve port, the third port is connected to the second end of the refrigerant flow path, and the opening of the second port and the third port of the regulating valve can be adjusted; the controller is electrically connected to the regulating valve to control the adjustment The opening of the second port and the third port of the valve. The heat pump unit of the present invention is beneficial to realize the adjustment of the flow rate of the refrigerant flowing to the heat recovery device between 0% and 100%.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a heat pump unit. Background technique [0002] The heat pump system in the related art generally installs a heat recovery device between the four-way valve and the exhaust port of the compressor to recover heat, but the heat recovery amount cannot be adjusted from 0 to 100%, and can only be adjusted between recovery or no recovery , which can easily lead to system instability. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a heat pump unit, which can continuously adjust the amount of heat recovery within 0-100%. [0004] The heat pump unit according to the embodiment of the present invention includes: a compressor having an exhaust port and an air return port; a reversing assembly having a first valve port to a fourth va...
