Abstract

The invention provides a two-way dry filter. The two-way dry filter includes: a housing, a first one-way valve assembly, a second one-way valve assembly and a dry filter assembly, and the dry filter assembly is abutted between the first one-way valve assembly and the second one-way valve assembly; The first one-way valve assembly has a first inlet valve port and a first outlet valve port; the second one-way valve assembly has a second inlet valve port and a second outlet valve port; the dry filter assembly includes: a dry outer core and a filter inner core , the drying outer core is set in the housing cavity, and has a mounting hole connecting the first inlet valve port and the second inlet valve port, and the filter inner core is set in the mounting hole; the first inlet valve port, the drying filter assembly and the second outlet The valve port forms a first one-way flow path; the second inlet valve port, the dry filter assembly and the first outlet valve port form a second one-way flow path. The technical solution of the invention can solve the problem of low utilization efficiency of the filter material of the filter in the prior art.

Description

technical field [0001] The invention relates to the field of air conditioner equipment, in particular to a bidirectional dry filter. Background technique [0002] Two-way dry filter is generally used in heat pump air-conditioning system. It is equipped with dry and filtering material. This material can effectively prevent impurities and soluble substances from entering the air-conditioning system. At the same time, this material absorbs acidic substances in excess water. ; so as to avoid the occurrence of system dirty blockage, ice blockage, etc., ensure that the system works in the best state, and reduce the maintenance workload of the staff. [0003] In the prior art, because the filter element of the two-way filter drier is a porous material, it is the channel through which the refrigerant must flow, so how to ensure that "no matter how many impurities have been filtered in the filter cavity, the porous channel of the filter element Always open" is important. [0004] S...
