Embodiment Construction
[0044] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0045] The embodiment of the present invention provides a solution. When the frosting condition is satisfied, the target exhaust temperature is obtained according to the outdoor environmental conditions, and the opening of the electronic expansion valve is determined according to the difference between the actual exhaust temperature and the target exhaust temperature. This makes the target exhaust temperature also change when the outdoor temperature is low, avoiding the rapid reduction of the opening of the electronic expansion valve, and delaying the worsening of frosting.
[0046] Such as figure 1 as shown, figure 1 It is a schematic diagram of the terminal structure of the hardware operating environment involved in the solution of the embodiment of the present invention.
[0047] The terminal in this embodiment o...

The invention discloses a control method of an air conditioner. The control method of the air conditioner comprises the following steps of judging whether the air conditioner meets a preset frosting condition or not according to an outdoor environment condition and the running duration of a compressor of the air conditioner when the air conditioner is in a heating mode; if yes, obtaining the target exhaust temperature according to the outdoor environment condition; and determining the opening degree of an electronic expansion valve in the air conditioner according to the difference value between the actual exhaust temperature and the target exhaust temperature. The invention also discloses the air conditioner and a computer readable storage medium. When the frosting condition is met, the target exhaust temperature is obtained according to the outdoor environment condition, and the opening degree of the electronic expansion valve is determined according to the difference value between the actual exhaust temperature and the target exhaust temperature, so that the target exhaust temperature changes when the outdoor temperature is low, rapid reduction of the opening degree of the electronic expansion valve is avoided, and deterioration of frosting is delayed.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method of the air conditioner, the air conditioner and a computer-readable storage medium. Background technique [0002] When the inverter air conditioner is heating, the refrigerant inside the outdoor heat exchanger evaporates and absorbs heat. If the outdoor temperature is too low, frost may appear on the surface of the heat exchanger, which will make the heat transfer of the low-pressure side of the system worse, and the pressure will drop, which will further affect To the high pressure, the high pressure is also reduced, and the actual exhaust temperature is also reduced. [0003] Inverter air conditioners usually control the opening of the electronic expansion valve according to a fixed target exhaust temperature. However, when the opening of the electronic expansion valve is controlled according to a fixed target exhaust temperature, in order to ...
