The control method of increasing the low-temperature heating heat of inverter air conditioner

The invention provides a control method for increasing low-temperature heating heat of a varied-frequency air conditioner. After an outdoor electronic control chip of the air conditioner receives an instruction to start an indoor low-temperature heating mode, the method comprises the following steps: step 1: the outdoor electronic control chip responses outdoor ambient temperature and environmentrelative humidity so that the air conditioner can enters into a corresponding low-temperature heating running state; and step 2: after the air conditioner enters into a low-temperature heating running state, a compressor runs for a corresponding heating time according to a designated heating frequency, then the air conditioner enters into a defrosting operation and an outdoor heat exchanger of the air conditioner can be defrosted through reversing a four-way valve in the air conditioner, wherein before the defrosting operation in the step 2 and in the entire process of defrosting operation, the operation frequency and time of the compressor can be changed on condition that the compressor of the air conditioner keeps running all the time. The method provided by the invention can response the changes of ambient temperature and relative humidity and can effectively improve low-temperature heating heat of the varied-frequency air conditioner.
