Problems solved by technology

When the air conditioner is in the heating operation mode, there may be problems such as high sound in the room, noise from the outdoor unit entering the room, and additional noise due to the increase in load of the compressor at low speed, so when the indoor fan is running at a low wind speed , the compressor will reduce the noise generated by the above problems by reducing its maximum operating frequency, but this limits the heating capacity of the air conditioner and cannot achieve rapid heating, which

Abstract

The invention discloses a control method of an air conditioner. The control method comprises the steps that whether the air conditioner is in a heating operation mode or a refrigerating operation mode is detected; in the heating operation mode, whether the current rotating speed of an indoor fan is in a preset heating low-air interval or not is judged, if not, a compressor is controlled to operate at the maximum heating frequency, and if yes, the actual operation frequency of the compressor is controlled according to the indoor environment temperature and the current rotating speed of the indoor fan; the actual operation frequency of the compressor is reduced along with the increase of the indoor environment temperature; and in the refrigerating operation mode, whether the current rotating speed of the indoor fan is in a preset refrigeration low-air interval or not is judged, if not, the compressor is controlled to operate at the maximum refrigeration frequency, if yes, the actual operation frequency of the compressor is controlled according to the indoor environment temperature and the current rotating speed of the indoor fan, and the actual operation frequency of the compressor is increased along with the increase of the indoor environment temperature. According to the control method of the air conditioner, refrigerating and heating can be rapidly achieved, and the air conditioner has the advantages of being low in energy consumption, low in noise, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method. Background technique [0002] An air conditioner in the related art usually includes a compressor, an indoor fan and an evaporator. When the air conditioner is in the heating operation mode, there may be problems such as high sound in the room, noise from the outdoor unit entering the room, and additional noise due to the increase in load of the compressor at low speed, so when the indoor fan is running at a low wind speed , The compressor will reduce the noise generated by the above problems by reducing its maximum operating frequency, but this limits the heating capacity of the air conditioner, cannot achieve rapid heating, and affects the user experience. [0003] When the air conditioner is in the cooling operation mode, the compressor may have liquid shock phenomenon due to insufficient evaporation of the evaporator. When the indo...
