Problems solved by technology

[0005] In order to solve the problem that the pressure unloading valve in the air conditioning system generates noise during operation, the purpose of the present invention is to provide a pipeline structure that reduces the opening noise of the pressure unloading valve in the air conditioning system, by changing the pipeline of the pressure unloading valve in the air conditioning system The connection method increases the cross-sectional area of ​​the gaseous refrigerant circulation channel at the back end of the pressure unloading valve, so that the flow velocity of the gas refrigerant in the pipeline after it comes out of the pressure unloading valve is buffered, greatly reducing the noise of the pressure unloading valve when it is working

Embodiment Construction

[0018] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0019] figure 1 It is a schematic diagram of the pipeline structure for reducing the opening noise of the pressure unloading valve of the air conditioning system provided by the present invention. Such as figure 1 As shown, the connection mode of the pipeline structure is: the liquid side shut-off valve 112 for on-line is connected with the electronic expansion valve 111 through the pipeline, and the rear end of the electronic expansion valve 111 is connected with the outdoor heat exchanger 109 through the pipeline, and the outdoor heat exchanger 109 links to each other with four-way reversing valve 110 through pipeline, and four-way reversing valve 10 has four pipes, and the flow direction of four pipes is different during cooling and heating, and can play the effect of refrigerant reversing. The...

Abstract

The invention discloses a pipeline structure for reducing noise of an opening the pressure unloading valve of an air conditioning system. The front end of the pressure unloading valve is connected to the outlet manifold of an oil separator through a high pressure pipeline, and the rear end of the pressure unloading valve is connected to the inlet manifold of the oil separator through a connecting pipeline while the cross sectional area is larger than that of the high pressure pipeline. When gas pressure refrigerant flows to the inlet manifold of a gas-liquid separator, even though the pressure difference between the front and rear end of the pressure unloading valve is very large, the flow rate of gas refrigerant in pipelines is buffered as the cross sectional area of the passage of circulating passage for gas refrigerant is increased, so that noise can be decreased obviously.

Description

technical field [0001] The invention relates to a pipeline structure in an air conditioner, and more specifically, relates to a pipeline structure for reducing the opening noise of a pressure unloading valve of an air conditioner system. Background technique [0002] At present, the air conditioning system generally has a pressure unloading valve. When the air conditioner is started or running, it is opened through a certain control program to adjust the pressure range and prevent the pressure from being too high or too low. However, currently there are air-conditioning systems with pressure unloading valves. When designing the pressure unloading valves, they are only set up to meet the needs of the system, without considering the noise generated by the valves when they are working. When it is turned on, it makes a "chichi" sound, which is very noisy and interferes with people's work and life. [0003] In addition, people nowadays have higher and higher requirements for hom...
