Air conditioner gas bypass noise reduction method and structure

Abstract

The invention discloses an air conditioner gas bypass noise reduction method and a structure, and relates to the field of air conditioner noise reduction, in particular to a noise reduction method and a noise reduction structure of an air conditioner gas bypass pipe. The air conditioner gas bypass noise reduction method comprises the following steps: A. arranging a gas bypass noise reduction structure between a high-pressure exhaust pipe and a low-pressure gas suction pipe of the air conditioner, wherein the gas bypass noise reduction structure is a shunt noise reduction component at one end of the low-pressure gas suction pipe; and B. calculating the amount of shunt flow by adopting high-pressure and low-pressure bypass coolants, and identifying the number of shunt pipes of the shunt noise reduction components, the size of the diameter of each pipe, and the gas flow velocity in each pipe. With the adoption of the air conditioner gas bypass noise reduction method and the structure, the flow impact speed of the coolants entering a gas suction side is slowed down through the condition that a bypass fluid is shunted in proportion, so that the gas bypass noise is reduced, the low-frequency vibration amplitude of a copper pipe is reduced, and the service life of the gas bypass pipe is prolonged.

Description

technical field [0001] The invention relates to a noise reduction technology of an air conditioner, in particular to a noise reduction method and structure of an air conditioner air bypass pipe. Background technique [0002] In order to prevent the low pressure from being too low in the low-temperature operation of the existing air conditioner, the structure and scheme of bypassing the gaseous refrigerant on the high-pressure side to the low-pressure side is a single-pipeline method, that is, an exhaust bypass connection pipe, a bypass solenoid valve and a Root suction bypass way. There is only a single bypass port for spraying to the low-pressure suction pipe, which leads to the problems of high air flow noise, severe vibration of the bypass pipe and suction pipe, and obvious low-frequency noise when the group is running at low temperature. Contents of the invention [0003] One of the objectives of the present invention is to provide an air-bypass noise reduction method...
