Abstract

The invention discloses a control method and a control device for a chassis heater of an air conditioner outdoor unit and an air conditioner. The control method comprises the following steps of: calculating a difference value obtained by subtracting a preset third time length from an accumulated operation time length of a compressor of the air conditioner in a previous defrosting period; and afterthe chassis heater is closed in the previous defrosting period and the accumulated operation time length of the compressor of the air conditioner exceeds the difference value, judging whether a second outdoor environment temperature T is continuously lower than a second threshold temperature for a fourth time length or not, and if yes, starting the chassis heater, and closing the chassis heater after a fifth time length. According to the control method and the control device for the chassis heater of the air conditioner outdoor unit and the air conditioner, the chassis heater is not controlled to be closed when the outdoor environment temperature is higher than a certain temperature value, but is controlled to be closed when the outdoor environment temperature is lower than the certain temperature value; and different chassis heater starting duration times are designed in cooperation with different air conditioner operation modes, so that electric energy is saved on the premise of ensuring the deicing effect.

Description

technical field [0001] The invention relates to the field of air conditioner control methods, in particular to a control method, a control device, and an air conditioner for a chassis heater of an outdoor unit of an air conditioner. Background technique [0002] In northern my country and some countries with cold weather, the temperature is low in winter, and the chassis and outer coil of the outdoor unit of the air conditioner are easy to freeze, resulting in low heat exchange efficiency of the outdoor unit during the heating operation of the air conditioner, and the temperature of the air blown out by the indoor unit Not high enough. One way of deicing is to turn on the defrosting process. When the air conditioner is heating, the outdoor unit of the air conditioner is an evaporator; Defrost effect. [0003] When the air conditioner is in the defrosting process, the internal unit of the air conditioner becomes a heat-absorbing condenser. The defrosting process generally do...
