Description
Technical field
The utility model relates to refrigerant filtration art in the air conditioner test process, more particularly, relates to a kind of test macro of air conditioner and the filter of refrigerant thereof.
Background technology
In order to guarantee the air-conditioning quality, producer need test air-conditioning at the air-conditioning before sales.General indoor set links to each other through tube connector with off-premises station.Because residual in some passages of the air-conditioning that just dispatched from the factory have impurity such as dust; When refrigerant when being attached with the passage of impurity; Impurity can mix with refrigerant, heats or kind of refrigeration cycle through tube connector together, can cause air-conditioning system to be stopped up; Make that compressor of air conditioner is prone to be damaged, reduced the service life of compressor of air conditioner.Stop up air-conditioning system for fear of impurity, thereby improve the service life of compressor of air conditioner, the filter of refrigerant is set between indoor set and off-premises station during general test.
Existing filter mainly comprises: housing, be positioned at the filter core of enclosure interior, the top cover that is positioned at the housing top and links to each other with housing seal; The space that the inwall of housing and the outer wall of filter core surround is an adapter cavity; Housing is provided with relative import and outlet; Filter core is a hollow structure, and the inner chamber of filter core and adapter cavity are separate, and the inner chamber of top cover is connected with filter core and is isolated with adapter cavity; The inner chamber of top cover is connected with outlet on the housing, and filter core filters the refrigerant that contains impurity, with the impurity detention in the refrigerant in adapter cavity.The course of work of filter is following:
