Abstract

The invention relates to the technical field of intelligent household electrical appliance, and discloses a method and device for freezing-prevention protection of an air conditioner and the air conditioner. The method comprises the following steps of obtaining a current coil pipe temperature of the air conditioner; under the condition that the absolute value of the difference value between the current coil pipe temperature and a preset freezing-prevention protection temperature is smaller than the first set value, increasing the wind speed of a fan to a second wind speed from a first wind speed, determining the obtained difference value between the current air returning temperature and the current coil pipe temperature as a first superheat degree and saving the difference value; and underthe condition that the fan runs at the second wind speed, determining the obtained difference value between the current air returning temperature and the current coil pipe temperature as a second superheat degree, under the condition that the absolute value of the superheat difference value between the first superheat degree and the second superheat degree is larger than the second set value, adjusting the preset freezing-prevention protection temperature, and carrying out freezing-prevention protection running according to the adjusted preset freezing-prevention protection temperature. Therefore, accuracy of freezing-prevention protection of the air conditioner can be improved.

Description

technical field [0001] The present application relates to the technical field of smart home appliances, for example, a method and device for anti-freezing protection of an air conditioner, and an air conditioner. Background technique [0002] With the development of artificial intelligence technology, air conditioners are becoming more and more intelligent. When the air conditioner is in use, in order to prevent the evaporator from freezing due to the low temperature of the evaporator when the air conditioner is running in cooling or dehumidification mode, or liquid refrigerant entering the compressor and causing liquid shock damage to the compressor, antifreeze protection is usually implemented. [0003] At present, the anti-freezing protection may include: setting multiple anti-freezing protection temperatures, when the coil sensor detects that different anti-freezing protection temperatures are reached, enter different processing stages of anti-freezing protection, and re...
