Abstract

The invention discloses an air conditioner anti-freezing control method and device. The air conditioner anti-freezing control method comprises the steps of detecting a working mode of an air conditioning unit; selecting an anti-freezing mode corresponding to the working mode according to the working mode, wherein the anti-freezing mode is a control mode for conducting anti-freezing protection on the air conditioning unit in the working mode; controlling the anti-freezing protection conducted on the air conditioning unit according to the selected anti-freezing mode. By means of the air conditioner anti-freezing control method and device, the problem that the air conditioning unit is in the working modes except a heating mode and accordingly the air conditioning unit is easily frozen off is solved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner antifreeze control method and device. Background technique [0002] In winter, the air conditioning unit is usually in heating mode to heat the room. Due to the low temperature in winter, in order to prevent the air conditioning unit from freezing, it is usually necessary to turn on the antifreeze protection for the air conditioning unit. [0003] However, the inventors have found that the existing air conditioning units only consider setting antifreeze protection in the heating mode operation state, and only implement antifreeze protection through the return air temperature. The non-operation state of the heating mode and the cooling and ventilation modes all lack antifreeze protection, which is easy A condition that causes the air conditioning unit to freeze. For example, if the user mistakenly selects the cooling mode when the outdoor temperature is low in ...
