Abstract

The method for controlling the amount of refrigerant provided by the invention relates to the technical field of air conditioning. The refrigerant quantity control method is applied to the automatic adjustment system of air conditioner refrigeration. The automatic adjustment system of air conditioner refrigeration includes the air conditioner and the refrigerant adjustment device. One end of the internal unit is connected to the four-way valve through a low pressure pipeline, and the other end is connected to the heat exchanger through a high pressure pipeline. Pipe connection. The discharge tank of the refrigerant adjusting device is connected to the first solenoid valve, the first solenoid valve is connected to the high-pressure pipeline, the liquid filling tank is connected to the second solenoid valve, and the second solenoid valve is connected to the low-pressure pipeline. The method for controlling the amount of refrigerant includes: judging the state of the amount of refrigerant in the air conditioner; when the amount of refrigerant is too much, controlling the opening of the first electromagnetic valve so that too much refrigerant in the high-pressure pipeline is introduced into the drain tank; When the amount is insufficient, the second electromagnetic valve is controlled to open, so that the refrigerant in the liquid filling tank is introduced into the low-pressure pipeline. By adopting the method for controlling the amount of refrigerant, the amount of refrigerant can be adjusted efficiently and safely.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a method for controlling the amount of refrigerant. Background technique [0002] Generally, an air conditioner includes an outdoor unit and an indoor unit respectively connected to the outdoor unit. During the commissioning stage of the air conditioner factory, the control of the amount of refrigerant has always been a labor-intensive and time-consuming project. How to efficiently and safely adjust the amount of refrigerant is a technical problem that needs to be solved urgently. Contents of the invention [0003] The problem solved by the invention is how to efficiently and safely adjust the amount of refrigerant. [0004] In order to solve the above problems, the present invention provides a method for controlling the amount of refrigerant, which is applied to an automatic adjustment system for refrigeration of an air conditioner. The automatic adjustment s...
