Refrigerating agent pipeline horizontal type gas-liquid separator in front of compressor

Abstract

A refrigerating agent pipeline horizontal type gas-liquid separator in front of a compressor comprises a horizontal barrel, a front cover, a rear cover, a gas outflow pipe and liquid watching devices;the horizontal barrel is a horizontally placed round iron barrel, and an inlet pipe is a straight pipe with an inclined notch; the front cover is formed by welding an arc-shaped sphere panel and a cylinder shell; the rear cover is a round plate; the gas outflow pipe is a pipe with the two ends being straight pipes and the middle bent in a smooth transition manner; the number of the liquid watching devices is three; and each liquid watching device comprises an internal thread sleeve and an observing window, and each observing window comprises a lens frame and a lens. In the refrigerating agentpipeline horizontal type gas-liquid separator in front of the compressor, the inlet pipe is arranged to make a refrigerating agent entering the horizontal barrel away from the gas outflow pipe as much as possible, the gas-liquid separation distance is increased, the inlet pipe with the inclined notch in the tail end makes liquid and gas in the refrigerating pipe distributed faster, and the gas-liquid separation speed is increased.

Description

technical field [0001] The invention relates to the technical field of central air conditioning, in particular to a horizontal gas-liquid separator for a refrigerant pipeline before a compressor. Background technique [0002] The machines that provide cooling capacity for central air conditioners are generally large chillers, and a huge amount of refrigerant is required in the refrigerant pipeline. The position of the gas-liquid separator is after the evaporator in the refrigerant pipeline and before the compressor. On the one hand, it is used to prevent the liquid refrigerant in the compressor from entering the compressor, causing damage to the compressor. On the other hand, the gas-liquid separator simultaneously It plays the role of liquid storage, because large chillers use a large amount of refrigerant, and different amounts of refrigerant can be used under different working conditions. [0003] The air-cooled unit adopts an air-cooled condenser (copper tube expanded a...

Problems solved by technology

However, it is difficult for the horizontal gas-liquid separator to use gravity as a booster for gas-liquid separation, so it is necessary to work hard on the structure to ensure the same separation effect as the vertical gas-liquid separator, and to achieve a balance between space and effect
