Abstract

The invention relates to an air conditioner control method, and provides the air conditioner control method by using a booster heater to shorten defrosting time and cold air prevention time. The air conditioner control method in an indoor heating state comprises the following steps: driving the booster heater during the cold air prevention of an air conditioner, and judging whether temperature of an indoor heat exchanger is higher than a first set temperature, if yes, driving an indoor fan; if not, keeping halted state of the indoor fan until the temperature of the indoor heat exchanger is higher than the first set temperature; and setting an indoor unit into a refrigeration cycle during the defrosting of the air conditioner, turning off the indoor fan, and driving the booster heater. The booster heater is arranged below the indoor heat exchanger. The method aims at the air conditioner containing the electric booster heater, and the electric booster heater is started during the air conditioner heating operation, the cold air prevention and the defrosting so as to shorten the cold air prevention time and the defrosting time, and extends the usage of the booster heater.

Description

technical field

[0001] The invention relates to an air conditioner control method, in particular to a control method for preventing cold wind and defrosting in the heating cycle of the air conditioner. Background technique

[0002] Air conditioners are generally divided into integral type and split type. In terms of functions, the integrated type and the split type are roughly the same, except that the integral type installs the evaporator, compressor, condenser, and fan in a chassis; the split type is equipped with an indoor heat exchanger (evaporator) in the indoor unit located indoors. or condenser) and an indoor fan, etc., an outdoor heat exchanger (condenser or evaporator), a compressor, and an outdoor fan are arranged in the outdoor unit. At least one of the indoor unit and the outdoor unit is provided with an expansion device, and the separated indoor unit and outdoor unit are connected through refrigerant piping.

[0003] On the one hand, when the air conditioner i...
