Problems solved by technology

However, in the above-mentioned defrosting operation, because too much refrigerant flows into the heat exchanger of the indoor unit, it will cause relatively large flow noise of the refrigerant in the refrigerant pipe.
In particular, since the indoor fan does not work, the flow noise of the refrigerant generated above will make the user feel uncomfortable.

Abstract

This invention relates to electronic valve controlling method of air conditioner. It includes: steps for air conditioner entering into defrosting operation mode; the electronic valve, which is used to provide refrigerants to indoor machine, closes and operates according to the fixed quantify under the said defrosting operation mode. This invention can reduce noise generated during defrosting operation.

Description

technical field [0001] The present invention relates to a control method of an electronic valve, and more specifically relates to a defrosting operation during the operation of an air conditioner. By properly adjusting the opening degree of the electronic valve, the noise generated in the indoor unit can be reduced and the defrosting operation can be effectively performed. Electronic valve control method of air conditioner for defrosting operation. Background technique [0002] A general air conditioner is a machine that can forcefully transfer heat between the inside of the machine and the outside of the machine through processes such as compression, condensation, expansion, and evaporation of the refrigerant. Recently, the above-mentioned air conditioners are widely used in order to provide users with a comfortable indoor environment, and achieve cooling or heating operations by switching the circulation of the refrigerant to the forward or reverse direction of the air con...
