Embodiment 1

[0023] figure 1 It is a flowchart of an air conditioner control method according to an embodiment of the present invention. Wherein, the air conditioner operates in cooling mode. Such as figure 1 As shown, the air conditioner control method in the embodiment of the present invention includes the following steps:

[0024] S101: Identify that the compressor in the air conditioner operates at a minimum operating frequency.

[0025] According to an embodiment of the present invention, identifying the operation of the compressor in the air conditioner according to the minimum operating frequency includes: obtaining the operating frequency of the compressor at the current moment, comparing the operating frequency at the current moment with the minimum operating frequency, and if the operating frequency at the current moment is equal to the minimum operating frequency If the minimum operating frequency is the same, it is determined that the compressor operates at the minimum opera...

Embodiment 2

[0070] image 3 It is a schematic block diagram of an air conditioner control device according to an embodiment of the present invention. Such as image 3 As shown, the air conditioner control device 100 according to the embodiment of the present invention includes: an identification module 10 , a first acquisition module 20 , a second acquisition module 30 , a third acquisition module 40 and a control module 50 .

[0071] Among them, the identification module 10 is used to identify the operation of the compressor in the air conditioner according to the minimum operating frequency; the first acquisition module 20 is used to acquire the target operating frequency of the air conditioner at the current moment; the second acquisition module 30 is used for when the target operating frequency is lower than the minimum operating frequency , to obtain the outdoor temperature and the indoor temperature; the third obtaining module 40 is used to obtain the target inlet temperature of th...

Abstract

The invention discloses an air conditioner control method and device. The air conditioner operates in a cooling mode. The method includes the following steps: identifying that the compressor in the air conditioner operates at the lowest operating frequency; obtaining the target operating frequency of the air conditioner at the current moment; if If the target operating frequency is less than the minimum operating frequency, obtain the outdoor temperature and indoor temperature; obtain the target inlet temperature of the evaporator according to the outdoor temperature and the indoor temperature; adjust the electronic The opening of the expansion valve effectively solves the technical problem in the prior art that the output cooling capacity of the air conditioner is greater than the actual indoor cooling capacity when the air conditioner operates at the lowest frequency.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device. Background technique [0002] In the related art, the operation mode of the inverter air conditioner is as follows: at the beginning, the compressor is controlled to run at high frequency, and the indoor temperature drops rapidly. (The preset value is 1°C~5°C, depending on the setting of each manufacturer), the air conditioner will reach the temperature and stop, that is, the compressor will stop running. As time goes by, when the indoor temperature rises to the condition for automatic start, the air conditioner will restart open. As the difference between the indoor temperature and the preset temperature decreases, the operating frequency of the compressor will also decrease. Finally, in the stage before the shutdown, the compressor will run at the minimum frequency that can be operated, so that the air conditioner can cool...
