Anti-freezing method for air conditioner, air conditioner, and computer-readable storage medium

Abstract

The invention provides an air conditioner anti-freezing method, an air conditioner and a computer readable storage medium. The method comprises the following steps that 1, the current working state ofthe air conditioner is acquired; 2, if the current working state is that when the running duration of the air conditioner entering the refrigerating mode exceeds the first preset time duration, a current preset interval is determined according to the absolute value of the difference value between the real-time preset temperature value and the real-time indoor environment temperature; 3, the inletpressure value of an evaporator is detected; and 4, the entering time and the exiting time of the anti-freezing mode is determined according to the inlet pressure value and the pressure threshold value corresponding to the current preset interval. The air conditioner comprises a controller, and the controller is used for executing the anti-freezing method of the air conditioner when the computerprogram stored in a memory is executed. The computer readable storage medium is stored with the computer program, and when the computer program is executed by the controller, the anti-freezing methodfor the air conditioner is realized. According to the method, the accuracy of controlling the air conditioner to enter the anti-freezing state can be improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner antifreeze method, an air conditioner applying the air conditioner antifreeze method, and a computer-readable storage medium applying the air conditioner antifreeze method. Background technique [0002] In the use of air conditioners, frosting of evaporators in cooling mode is a common problem. Most designers now install a temperature-sensing package on the evaporator, use the temperature-sensing package to collect the evaporator tube temperature, and use the evaporator tube temperature to control the unit to enter and exit the anti-freezing mode. Although this method can also achieve the anti-freezing effect, the cost is relatively high when using the anti-freezing temperature sensing package for anti-freezing. In addition, since the anti-freezing temperature sensing package works in an alternating cold and hot environment, the temperature se...

Although this method can also achieve the anti-freezing effect, the cost is relatively high when using the anti-freezing temperature sensor package to prevent freezing

In addition, since the anti-freezing temperature sensing package works in an alternating cold and hot environment, the temperature sensing package is prone to problems such as failure, detection deviation, and service life, resulting in the failure of the anti-freezing logic of the unit, thus affecting the air-conditioning system due to the reliability of the temperature sensing package.
