Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing air conditioner frequently turns on and off the compressor during cooling/heating, which leads to large fluctuations in the indoor ambient temperature and reduces user comfort and the service life of the compressor. Problem, the present invention provides a control method for an air conditioner, the air conditioner includes an indoor unit, an outdoor unit, a compressor and an electronic expansion valve, and the

Embodiment 1

[0035] Such as figure 2 As shown, the air conditioner executes cooling mode; obtains the indoor ambient temperature; judges whether the indoor ambient temperature reaches the first preset temperature T1; if so, switches the air conditioner from cooling mode to breeze mode, and then reduces the frequency of the compressor to decrease Open the electronic expansion valve, reduce the fan speed of the indoor unit and adjust the air deflector of the indoor unit to the highest position; if not, do not adjust the operation mode of the air conditioner and continue to obtain the indoor ambient temperature. After the air conditioner switches from the cooling mode to the breeze mode, continue to obtain the indoor ambient temperature, and judge whether the indoor ambient temperature reaches the second preset temperature T2; if so, switch the air conditioner from the breeze mode to the cooling mode, and then increase the compressor Frequency, increase the opening of the electronic expansio...

Embodiment 2

[0037] Such as image 3As shown, the air conditioner executes the heating mode; obtains the indoor ambient temperature; judges whether the indoor ambient temperature reaches the third preset temperature T3; if so, the air conditioner switches from the heating mode to the breeze mode, and then reduces the frequency of the compressor, Reduce the opening of the electronic expansion valve, reduce the fan speed of the indoor unit and adjust the air deflector of the indoor unit to the lowest position; if not, do not adjust the operation mode of the air conditioner and continue to obtain the indoor ambient temperature. After the air conditioner switches from the heating mode to the breeze mode, continue to obtain the indoor ambient temperature, and judge whether the indoor ambient temperature reaches the fourth preset temperature T4; if so, switch the air conditioner from the breeze mode to the heating mode, and then increase the compression Increase the opening of the electronic exp...

Abstract

The invention belongs to the technical field of air conditioners, and provides a control method used for an air conditioner, and the air conditioner in order to solve the problems that when existing air conditioners conduct refrigeration/heating, compressors are started and stopped frequently, consequently indoor ambient temperature fluctuation is large, user comfort is reduced, and the service life of the compressors is shortened. The control method includes the steps that an indoor ambient temperature and a current operation mode of the air conditioner are obtained; and according to the indoor ambient temperature and the current operation mode of the air conditioner, the operation mode of the air conditioner is selectively switched, and the frequency of a compressor, the opening degree of an electronic expansion valve and the fan rotating speed of an indoor unit are regulated. According to the control method used for the air conditioner, and the air conditioner, large fluctuation ofthe indoor ambient temperature can be avoided, thus the user comfort is improved, the compressor only conducts frequency decreasing and frequency increasing operation in the mode switching process, and is not stopped, frequent starting and stopping of the compressor are avoided, and thus the service life of the compressor is prolonged.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides an air conditioner control method and the air conditioner. Background technique [0002] The air conditioner is a device that can cool / heat the room. The control logic of the existing air conditioner is roughly as follows: in the cooling condition, the indoor fan rotates, the compressor rotates and the electronic expansion valve is opened. After the indoor temperature reaches the target temperature, the air conditioner When the air conditioner stops cooling, the indoor fan continues to rotate, the compressor stops and the electronic expansion valve is closed, and then the indoor temperature will rise. After the indoor temperature rises to a certain extent, the air conditioner will restart cooling, and the compressor will start again The air conditioner turns and the electronic expansion valve opens; under the heating condition, the indoor fan rotates, the compre...
