Embodiment Construction
[0023] The defrosting control method of the frequency conversion air conditioner of the present invention is used for the control of entering and exiting the defrosting mode during the operation of the frequency conversion air conditioner.
[0024] see figure 1 , the specific flow of the defrosting control method of the inverter air conditioner in the embodiment of the present invention is as follows:
[0025] When the air conditioner is turned on, it detects the discharge temperature of the compressor and the intermediate temperature of the indoor heat exchanger. The intermediate temperature of the indoor heat exchanger refers to the temperature detected by the temperature sensor located in the middle of the evaporator or condenser of the air conditioner indoor unit. In this embodiment, with 5s as a detection period, within 60s, record the compressor discharge temperature as Tp1 at the 0th s, Tp2 at the 5th s, ..., Tp13 at the 60th s, and record the intermediate temperature o...

The invention provides a defrosting control method of a variable frequency air conditioner, the air conditioner and a computer readable storage medium. The defrosting control method comprises the steps that the exhaust temperature of a compressor of the variable frequency air conditioner and the intermediate temperature of an indoor heat exchanger are detected according to a preset detection period, the variable quantity of the exhaust temperature of the compressor, the change rate of the variable quantity of the exhaust temperature of the compressor, the variable quantity of the intermediate temperature of an indoor heat exchanger and the change rate of the variable quantity of the intermediate temperature of the indoor heat exchanger is detected and determined according to a preset detection period, and if the above-mentioned parameters satisfy a pre-set condition within a pre-set time period, if yes, the air conditioner is controlled to enter or exit a defrosting mode. On the basis that the cost of an outdoor environment temperature sensor and an outdoor heat exchanger temperature sensor is saved, the defrosting control method has the advantages of being good in defrosting comfort and more accurate in defrosting control.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method for an inverter air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] When the inverter air conditioner works in the heating state, the heating end and the cooling end are switched through the four-way valve, and the outdoor heat exchanger is converted from the evaporator to the condenser. Due to the low temperature of the condenser, it is easy to cause the water vapor in the air to condense or condense. Hua, these water droplets and frost adhere to the condensation will affect the heat exchange of the condenser, affect the heating effect and bring additional power consumption, at this time, the air conditioner needs to stop heating to defrost. Usually, the defrost is defrosted to the outdoor heat exchanger by switching the heating end and the cooling end through the four-way valve. ...
