Title:
METHOD AND APPARATUS FOR ADJUSTING EXHAUST SUPERHEAT DEGREE OF HEAT PUMP DEVICE, AND HEAT PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/000828
Kind Code:
A1
Abstract:
The present application relates to the technical field of heat pump devices. Disclosed is a method for adjusting an exhaust superheat degree of a heat pump device. The method for adjusting the exhaust superheat degree of the heat pump device comprises: obtaining an exhaust superheat degree of a compressor of the heat pump device, and an operation mode of the heat pump device, the operation mode comprising a heating mode and a refrigeration mode; determining a refrigerant storage speed or a refrigerant release speed of a liquid storage apparatus according to the operation mode and the exhaust superheat degree, the refrigerant storage speed corresponding to the heating mode, and the refrigerant release speed corresponding to the refrigeration mode; and adjusting, to an opening degree corresponding to the refrigerant storage speed or the refrigerant release speed, a flow control valve for controlling the liquid storage apparatus. By using the method for adjusting the exhaust superheat degree of the heat pump device, both the refrigerant amount and the exhaust superheat degree in a circulation system can be considered, and the working efficiency of the heat pump device is improved. The present application further discloses an apparatus for adjusting an exhaust superheat of a heat pump device, and a heat pump device.
