Problems solved by technology

[0005] However, as mentioned above, when the compressor stops driving and expands the electronic valve, there is a pressure difference between the front end and the rear end of the electronic valve, so that the amount of refrigerant passing through the electronic valve suddenly increases, resulting in the failure of the electronic valve. Generates flow noise of refrigerant and makes users feel dissatisfied when using it

Abstract

This invention relates to electronic valve controlling method of air conditioner. It includes: steps for all the indoor machines stop working; steps for compressor stops working and after certain times, the opening degree of all electronic valves that connect to indoor machines reach full-opening degree. This invention can decrease refrigerants flowing noise of electronic valve after compressor stopping working.

Description

technical field [0001] The present invention relates to an electronic valve control method of an air conditioner, more specifically, it is an electronic valve control method for an air conditioner that reduces the flow noise caused by the refrigerant flowing in the electronic valve, thereby improving user satisfaction when using the air conditioner, and more specifically That is to say, in a multi air conditioner (multi air conditioner), when the compressor stops operating, the opening degree of the electronic valve is appropriately adjusted, thereby reducing the flow noise caused by the refrigerant flowing in the electronic valve. valve control method. Background technique [0002] A compound air conditioner in the general sense refers to a single outdoor unit connected to multiple indoor units, which can distribute and supply the refrigerant compressed by a compressor to the above-mentioned multiple indoor units, and perform air conditioning on each indoor space. . The t...
