Embodiment 1

[0023] figure 1 It is a flow chart of a control method of an air conditioner according to an embodiment of the present invention. Among them, the air conditioner operates in the cooling mode. like figure 1 As shown, the control method of the air conditioner according to the embodiment of the present invention includes the following steps:

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

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

Embodiment 2

[0070] image 3 It is a schematic block diagram of a control device of an air conditioner according to an embodiment of the present invention. like image 3 As shown, the control device 100 of the air conditioner 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] Wherein, the identification module 10 is used to identify that the compressor in the air conditioner operates at the lowest 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 to obtain the target operating frequency when the target operating frequency is less than the lowest operating frequency , obtain the outdoor temperature and indoor temperature; the third obtaining module 40 is used to obtain the target inl...

Abstract

The invention discloses an air conditioner control method and device. An air conditioner runs in a refrigeration mode. The method comprises the following steps that it is recognized that a compressorin the air conditioner runs according to the lowest running frequency; the target running frequency of the air conditioner at the current moment is obtained; if the target running frequency is lower than the lowest running frequency, the outdoor temperature and the indoor temperature are obtained; the target inlet temperature of an evaporator is obtained according to the outdoor temperature and the indoor temperature; and according to the target inlet temperature of the evaporator, the opening degree of an electronic expansion valve is adjusted. The technical problem that in the prior art, when an air conditioner runs with the lowest frequency, the output refrigerating capacity is larger than the indoor actual required cooling capacity is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, and in particular, to a control method and device of an air conditioner. 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 operate at a high frequency, and the indoor temperature drops rapidly. When the preset is 1℃~5℃, it will be different according to the setting of each manufacturer), the air conditioner will stop when it reaches the temperature, that is, the compressor will stop running. As time goes on, when the indoor temperature rises to the condition of automatic startup, the air conditioner will restart again. on. In the process of reducing the difference between the indoor temperature and the preset temperature, the operating frequency of the compressor will also decrease. Finally, before the shutdown, the compressor will operate at the minimum frequency ...
