Problems solved by technology

In the process of defrosting, the temperature of the room will drop, making people feel uncomfortable due to the temperature drop. At present, methods such as heat storage defrosting and bypass defrosting can reduce the indoor temperature drop to a certain extent, but they all have their defects and cannot widely used

Embodiment 1

[0018] Embodiment 1: An air-conditioning heating defrosting control method.

[0019] Such as figure 1 As shown, an air-conditioning heating and defrosting control method, the specific steps are as follows:

[0020] When the defrosting condition is met during the operation of the air conditioner in heating mode, the ambient temperature inside the unit is detected. When the internal ambient temperature T 内环 meet T 内环 > T1 judging condition, then control the unit to enter the accelerated defrosting mode; if the internal environment temperature T 内环 meet T 内环 ≤T1 judging condition, the control unit enters the normal defrosting mode; T1=15°C, the air conditioner enters defrosting at 25 minutes of heating operation, and the internal ambient temperature is 12°C at this time. 内环 内环 >15°C, enter accelerated defrosting control.

[0021] After entering the accelerated defrosting control, when the four-way valve starts to change direction, the control air deflector is adjusted to the...

Embodiment 2

[0025] Embodiment 2: a computer-readable storage medium.

[0026] A computer-readable storage medium is used for storing a computer program, and when the computer program is invoked by a processor, the air-conditioning, heating, and defrosting control method described in Embodiment 1 is implemented.

Embodiment 3

[0027] Embodiment 3: A wall-mounted air conditioner.

[0028] A wall-mounted air conditioner includes a processor and a memory, the memory is used to store a computer program, and when the computer program is invoked by the processor, the method for controlling heating and defrosting of the air conditioner described in Embodiment 1 is realized.

Abstract

The invention provides an air conditioner heating and defrosting control method, a computer-readable storage medium and an air conditioner. When the defrosting condition is met during the operation of the air conditioning heating mode, the ambient temperature inside the unit is detected, and if the internal ambient temperature meets the judgment condition, enter Accelerated defrosting mode, adjust the angle of the air deflector to the maximum upward angle, and at the same time detect the temperature of the inner pipe of the unit in real time, calculate the difference between the inner pipe temperature and the inner ambient temperature, and adjust the fan speed to accelerate defrosting according to the difference. According to the analysis and judgment of the detected parameters of the air conditioning unit, and then by adjusting the fan speed to increase the heat exchange between the room air and the indoor side heat exchanger, the defrosting efficiency can be effectively improved, and the temperature drop during defrosting can be reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner heating and defrosting control method, a computer-readable storage medium and an air conditioner. Background technique [0002] During the heating operation of the household split air conditioner, the outdoor unit is prone to frost at low temperatures. In order to ensure the heating capacity of the air conditioner, the reliability of the fan blades and the compressor, the system must be switched to the mode of passing high-temperature and high-pressure refrigerant to heat and defrost the condenser after a period of operation. In the process of defrosting, the temperature of the room will drop, making people feel uncomfortable due to the temperature drop. At present, methods such as heat storage defrosting and bypass defrosting can reduce the indoor temperature drop to a certain extent, but they all have their defects and cannot widely used.
