Problems solved by technology

[0005] When the system pressure is too high, it is difficult to effectively reduce the system pressure only by reducing the compressor frequency and fan speed, resulting in compressor shutdown, and quickly reducing the compressor frequency and fan speed will cause a sharp drop in air supply comfort and poor user experience

Abstract

The invention relates to the technical field of air conditioner pressure relief, and discloses a control method for air conditioner pressure relief. An air conditioner comprises a compressor, and a pressure relief valve communicates between an exhaust pipe and an air return pipe of the compressor; the method comprises the steps of obtaining a system pressure value of the air conditioner; determining the size relation between the system pressure value and the closing pressure value of the pressure release valve; and the opening degree of the pressure release valve is controlled according to the size relation between the system pressure value and the closing pressure value of the pressure release valve. In the application, the opening degree of the pressure release valve can be controlled according to the size relationship between the obtained system pressure value and the closing pressure value, so that the pressure in the exhaust pipe on the high-pressure side in the refrigerating system is released to the air return pipe on the low-pressure side, and therefore, the system pressure in the refrigerating system is better controlled, the system pressure is efficiently adjusted, and the refrigerating efficiency is improved. And the compressor can operate more stably, the air supply comfort is improved, and then the user experience is improved. The invention further discloses a control device for pressure relief of the air conditioner and the air conditioner.

Description

technical field [0001] The present application relates to the technical field of pressure relief of air conditioners, for example, to a control method and device for pressure relief of air conditioners, and an air conditioner. Background technique [0002] The air conditioner is one of the necessary household appliances. Because of its fast cooling and heating, it is widely used. When the air conditioner is running for cooling or heating, the air outlet position of the indoor unit is manually adjusted due to improper operation by the user or the external environment is too high. If the system pressure is too high, the system pressure will be too high. When the system pressure exceeds the maximum load allowed by the system, the air conditioner will be shut down or the compressor will be damaged, which will affect the service life of the air conditioner. Therefore, the system pressure of the air conditioner needs to be adjusted. [0003] In the related art, there is a control ...
