An embodiment of the invention discloses a defrosting control method and device for automatically detecting frost quantity of a heat pump system, relates to the technical field of heat pumps, and can solve the problem that a heat pump system of an air conditioner in the prior art cannot accurately control defrosting time of an outdoor heat exchanger so that the heat pump system of the air conditioner is poor in thermal comfort. According to a specific scheme, the method comprises the following steps: judging whether running time of the heat pump system is greater than or equal to first preset time or not; when the running time of the heat pump system is greater than or equal to the first preset time, acquiring initial power of an outdoor fan, maximum power of the outdoor fan and the temperature of a liquid tube of an outdoor heat exchanger, wherein the maximum power of the outdoor fan is a maximum value of the running power of the outdoor fan in the running time of the heat pump system; and determining the defrosting starting mode of the heat pump system according to the initial power of the outdoor fan, the maximum power of the outdoor fan and the temperature of the liquid tube of the outdoor heat exchanger. The defrosting control method and device are used for defrosting the heat pump system.
Description
technical field [0001] The invention relates to the technical field of heat pumps, in particular to a defrosting control method and device for automatic detection of frosting amount in a heat pump system. Background technique [0002] Air conditioning heat pump system 10 such as figure 1 As shown, it includes a compressor 101, a four-way reversing valve 102, an indoor heat exchanger 103, a throttling device 104, an outdoor heat exchanger 105 and an outdoor fan 106, wherein the outdoor fan 106 provides heat exchange to the outdoor heat exchanger 105 airflow. When the air-conditioning heat pump system 10 is in the heating state, the refrigerant is compressed by the compressor 101 and becomes a high-temperature and high-pressure gas. The high-temperature and high-pressure gas enters the indoor heat exchanger 103 through the four-way reversing valve 102, and the high-temperature and high-pressure gas passes through The indoor heat exchanger 103 releases heat and becomes a high...
