Level glass structure of air conditioning refrigerant filter

Abstract

The invention discloses a level glass structure of an air conditioning refrigerant filter, which comprises a shell; a filtering structure formed from a filtering net and a spring supporting the filtering net is arranged in the shell; and the shell is provided with a level window for observing the working state of the interior filtering structure and the flow direction of a refrigerant. The level window comprises an opening formed on the shell and a door-shaped window frame inlaid on the periphery of the opening, and an insertion slot is formed on the door-shaped window frame; the level window is also provided with a level glass, and the level glass is installed on the door-shaped window along the insertion slot and is fixed through a fixing element. A sealing element is also inlaid in the insertion slot. The level glass structure of the air conditioning refrigerant filter is simple in structure and convenient to manufacture and install. The flow situation of the refrigerant in the filter shell can be clearly observed and the filtering net can be observed through the level glass provided by the invention, the damage of the filtering net can be found in time, the filtering net or the filter can be replaced in time, and the normal operation of an air conditioner can be effectively ensured.

Description

technical field [0001] The invention relates to a refrigerant filter, in particular to a liquid sight mirror structure of an air conditioner refrigerant filter which can observe the state of the filter net in the filter through the liquid sight mirror and observe the flow direction of the refrigerant. Background technique [0002] Generally, an air conditioner is composed of a heater, a refrigerator, a purifier, etc., which can cool or heat or purify indoor air, and can also adjust indoor humidity to create a suitable indoor environment for users. [0003] Generally speaking, the working process of an air conditioner is as follows: the compressor compresses the gaseous refrigerant into a high-temperature / high-pressure refrigerant; the gaseous refrigerant compressed into a high-temperature / high-pressure state is cooled in the condenser; The refrigerant in the evaporator is converted into a low-temperature / low-pressure refrigerant; in the evaporator, through heat exchange, it ...

AI Technical Summary

Problems solved by technology

[0013] However, currently air conditioners use filters such as image 3 As shown, it is completely closed, and the internal filter cannot be found if it is damaged during use, which will seriously affect the normal operation of the air conditioner
