Title:
HEAT PUMP AIR CONDITIONING SYSTEM, CONTROL METHOD AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/005271
Kind Code:
A1
Abstract:
The present invention relates to a heat pump air conditioning system, a control method and a control device. The heat pump air conditioning system comprises: a compressor; an outdoor heat exchanger; and a bypass loop, wherein a first end of the bypass loop is connected to an exhaust pipe that is connected to the compressor, a second end of the bypass loop is connected to a suction pipe that is connected to the compressor, part of the bypass loop is coupled to the outdoor heat exchanger, and a bypass valve and an auxiliary throttling device are sequentially arranged on the bypass loop in a flow direction of a refrigerant. The control method comprises: acquiring the real-time temperature of an outdoor heat exchanger; acquiring the real-time ambient temperature of an external environment to determine an outdoor dew point temperature or an outdoor wet bulb temperature; and calculating the difference between the real-time temperature and the outdoor dew point temperature or the outdoor wet bulb temperature to determine whether defrosting is required. The control device comprises a temperature acquisition module, a calculation module and a processing module. The heat pump air conditioning system has a continuous heating function, with a pipeline having a simple structure and occupying little space, and the control method involves simple calculation.
