Problems solved by technology

However, usually the indoor evaporator has more than two heat exchange channels. When the indoor evaporator is biased due to manufacturing and other reasons, the temperature of some heat exchange channels of the indoor evaporator may already be very low, and the indoor Frosting and icing have occurred on the evaporator, but the

Abstract

The invention discloses an air conditioner as well as a freeze control method and device thereof. The freeze control method comprises the following steps of acquiring the coil temperature of an evaporator in an indoor unit and the back temperature of a compressor in an outdoor unit, and calculating the temperature difference value of the coil temperature and the back temperature; judging the coil temperature and the temperature difference value; and if the coil temperature is judged to be higher than a first temperature threshold and lower than or equal to a second temperature threshold and the temperature difference value is higher than or equal to a third temperature threshold, controlling the air conditioner to enter a freeze protection mode. By using the method, the air conditioner can be effectively prevented from entering the freeze protection mode, so that the air conditioner is prevented from having a fault, the service life the air conditioner is prolonged, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an antifreeze control method for an air conditioner, an antifreeze control device for an air conditioner, and an air conditioner. Background technique [0002] At present, when the air conditioner is used in some special occasions, such as when the ambient temperature of the outdoor unit is still running in cooling mode, the indoor heat exchanger in the air conditioner is prone to frost and ice, which affects the normal operation of the air conditioner . Usually, when there is frost and ice on the indoor heat exchanger, the air conditioner will perform the anti-freeze protection function. [0003] In related technologies, it is judged whether the air conditioner has entered the anti-freezing protection function by detecting the temperature in the middle of the coil on a certain heat exchange flow path in the indoor evaporator (the indoor heat exchanger is an evaporator ...
