Embodiment Construction

[0014] Normally, the refrigerant coming out of the solenoid valve first enters a U-shaped pipe 1', and then enters the evaporator 3 through the liquid separator 2. The arrows in the figure indicate the direction of refrigerant flow. The pipe diameter of existing U-shaped pipe 1' is as thick as the refrigerant pipe diameter behind the electromagnetic valve. When the solenoid valve is opened, a large amount of refrigerant liquid suddenly gushes out, and the liquid quickly impacts the pipe wall and elbow of the U-shaped pipe 1', generating a large impact noise. Due to the impact of the refrigerant, it will also cause the indoor unit pipeline and other Vibration of components produces vibration noise.

[0015] In the present invention, the pipe diameter of the above-mentioned U-shaped pipe 1' is thickened, which is one to two times larger than that of the existing U-shaped pipe 1'. In this way, when the solenoid valve is opened, due to the thickened pipe diameter, the space insid...

Abstract

In the invention, a U-shape pipe diameter of the refrigerant pipeline for the room unit is thickened, so that the impact noise and the structure vibration noise caused by the refrigerant that is passing through the refrigerant pipeline are reduced. The gas-phase and liquid phase refrigerant can be fully mixed in the thickened U-shape pipe and then enter into an evaporator, so as to improve the radiating effect of the evaporator.

Description

technical field [0001] The invention relates to a device and method for reducing the noise of an air conditioner indoor unit, in particular to an air conditioner indoor unit noise reduction device and method capable of reducing the noise generated by high-speed flow of refrigerant in a pipeline. Background technique [0002] With the improvement of living standards, people's requirements for the environment are getting higher and higher, and there are more requirements for air conditioners, such as air that meets hygienic requirements, suitable temperature, humidity, and sound are all necessary conditions to satisfy people. Annoying noises or sounds that do not meet the acoustic requirements can affect the effectiveness of the air conditioning system. How to control the noise of the air conditioning system and provide people with a quiet and comfortable environment is worth studying. It is of great practical significance to take appropriate technical measures in the design ...
