Problems solved by technology

[0003] However, in the existing conventional defrosting control mode, the absorption of heat into the room during defrosting will cause the indoor temperature to drop by about 3°C ​​to 8°C, resulting in the indoor temperature being significantly lower than the temperature set by the user, eventually causing the human body to poor comfort

Embodiment

[0043] see figure 1 , figure 1 It is a flow chart of an air conditioner control method provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0044] Step S101, calculating the difference between the outdoor pipe temperature of the air conditioner and the outdoor ambient temperature;

[0045] Specifically, the outdoor pipe temperature of the air conditioner is obtained through the temperature sensing package of the outdoor pipe of the air conditioner, and the outdoor ambient temperature is obtained through the outdoor ambient temperature sensing package, and then the difference between the outdoor pipe temperature of the air conditioner and the outdoor ambient temperature is calculated.

[0046] Step S102, according to the difference between the outdoor pipe temperature of the air conditioner and the outdoor ambient temperature, determine the time from the air conditioner to defrost;

[0047] Step S103, if the time since the ai...

Abstract

The invention discloses an air conditioner control method and device and an air conditioner system. The method includes the steps that the difference value of the outdoor pipe temperature of an air conditioner and the outdoor environment temperature is computed; the moment when the air conditioner enters the defrosting state is determined according to the difference value of the outdoor pipe temperature and the outdoor environment temperature; if the moment when the air conditioner enters the defrosting state is smaller than or equal to the preset time, the air conditioner is controlled to conduct the operation, corresponding to the model of the air conditioner, of increasing the indoor temperature; the model comprises a frequency-fixed machine and a frequency-variable machine. By the adoption of the air conditioner control method and device and the air conditioner system, the human body comfort of users during the air conditioner defrosting period can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning control method, device and air conditioning system. Background technique [0002] When the air conditioner is running in the heating season, the outdoor heat exchanger becomes an evaporator, causing the water in the outdoor humid air to condense into frost on the surface of the outdoor heat exchanger (the temperature of the outer pipe is lower than 0°C), and the frost will cause the outdoor heat exchange The efficiency is reduced, which affects the heating effect, so a defrosting operation is required. At present, most air conditioners adopt the conventional defrosting mode, that is, the four-way valve reversing, switching from the heating operation mode to the cooling operation mode, and using the work done by the compressor and the heat absorbed into the room to defrost. [0003] However, in the existing conventional defrosting control mode, absorb...
