Defrosting control method for air conditioner, air conditioner and computer readable storage medium

Abstract

The invention discloses a defrosting control method for an air conditioner. The method comprises the following steps that when the air conditioner runs in a heating mode, the dry bulb temperature andthe wet bulb temperature of an outdoor environment and the coil temperature of an outdoor heat exchanger are acquired in real time; the corresponding dew point temperature is obtained according to theacquired dry bulb temperature and the acquired wet bulb temperature, and the difference value between the dew point temperature and the coil temperature is calculated; the running time of a compressor of the air conditioner under the condition that the difference value is greater than 0 DEG C is accumulated, and the accumulated running time is obtained; and when the accumulated running time reaches the preset time, whether the preset defrosting condition is met or not is judged, if yes, the air conditioner is controlled to enter a defrosting state. The invention further discloses the air conditioner and a computer readable storage medium. The defrosting control method, the air conditioner and the computer readable storage medium can solve the technical problem of too frequent defrosting or untimely defrosting of the air conditioner due to a large judgment error of an existing air conditioner on the frosting degree of the outdoor heat exchanger.

Description

Technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a defrosting control method of an air conditioner, an air conditioner and a computer-readable storage medium. Background technique [0002] The air conditioner may produce frost during cooling and heating. If the air conditioner is not defrosted in time after the air conditioner is frosted, it will affect the use of the air conditioner. [0003] When the heat pump air conditioner is running in the heating mode, the temperature of the outdoor unit evaporator body will drop below 0℃, and the surrounding moisture will quickly condense into frost, which is a normal phenomenon. Existing heat pump air conditioners operate in heating mode, and generally use a fixed compressor continuous or cumulative operating time. When the compressor operating time reaches the set operating time, the outdoor ambient air dry bulb temperature and the outdoor unit evaporator are detected. Surf...
