Problems solved by technology

But at present, in Europe, North America and many small computer rooms, household air conditioners are used to dissipate heat. The air conditioner needs to run in cooling mode for a long time. better, which in turn will affect the pressure difference between the high and low pressure of the air conditioner system, resulting in poor circulation of refrigerant and poor cooling effect, resulting in low energy efficiency of the air conditioner

Abstract

The invention provides a control method of an air conditioner and a control device. The air conditioner comprises an outdoor unit, wherein the outdoor unit is provided with a compressor, an outdoor heat exchanger and a fan which is used for facilitating the radiation of the outdoor heat exchanger; the control method of the air conditioner comprises the steps: when the air condition works under a refrigeration mode, a pressure value of a high pressure end of the compressor and a pressure value of a lower pressure end of the compressor are detected; a pressure difference value between the high pressure end of the compressor and the lower pressure end of the compressor is calculated; the rotating velocity of the fan is controlled according to the pressure difference value and the pressure difference value is controlled in a preset range. According to the technical scheme, the pressure difference value between the high pressure end and the lower pressure end of the compressor is controlled within the preset range, the smooth circulation of a refrigerant in the air conditioner is ensured, and the energy efficiency of the air conditioner can be favorably improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and an air conditioner control device. Background technique [0002] The functional requirements of ordinary users for air conditioners are generally high-temperature cooling and low-temperature heating, and most designers only consider the needs of ordinary users in terms of design. But at present, in Europe, North America and many small computer rooms, household air conditioners are used to dissipate heat. The air conditioner needs to run in cooling mode for a long time. It is better, which in turn will affect the pressure difference between the high and low pressure of the air conditioner system, resulting in poor circulation of the refrigerant and poor cooling effect, resulting in low energy efficiency of the air conditioner. [0003] Therefore, how to effectively maintain the pressure difference between the high-pressure en...
