The filtering device for the air conditioning refrigerants has the advantages of simple structure, reasonable arrangement, low manufacturing cost and the like.

Description

A kind of filter of air-conditioning refrigerant

Technical field

The utility model relates to refrigeration industry technical field, particularly a kind of filter of air-conditioning refrigerant.

Background technology

Cold-producing medium claims again refrigeration working medium, is commonly called as snow kind in some areas, south.It is in refrigeration system, constantly circulate and pass through the state variation of itself with the operation material of realization refrigeration.Cold-producing medium absorbs the heat of the medium that is cooled (water or air etc.) and vaporizes in evaporimeter, transfers heat to surrounding air or water and condensation in condenser.

Cold-producing medium all can contain impurity conventionally, therefore need filter to filter the impurity of cold-producing medium the inside, prevent that refrigeration system pipeline is blocked, make carrying out smoothly of whole refrigeration system, the piping filter that air conditioner uses at present generally adopts screen pack, this screen pack is arranged on the joining place of two copper pipes, although can remove to a certain extent impurity, but area of filter net is little, use a period of time rear impurity easily to stop up screen pack mesh, filtration resistance is increased, make filter efficiency low, waste energy, and this filter is generally fixed, conventionally can not pull down clean and maintenance, if need to change filter, maintenance cost is just very high.

Therefore be necessary the structure of existing filter to carry out technological innovation further.

Utility model content

The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, the filter of air-conditioning refrigerant reasonable in design, easy to use.

For achieving the above object, the technical solution adopted in the utility model is:

The filter of a kind of air-conditioning refrigerant described in the utility model, comprise two copper pipes and filter body, one end of two copper pipes is closely nested in respectively in the connection chamber that filters body two ends, one end of two copper pipes is fixedly installed respectively and the retainer plate that filters pipe end and match mutually, and retainer plate one end face is compressing the termination of filtering body; Copper pipe is also nested with the pressure pipe matching mutually with retainer plate, after the nested retainer plate of inner chamber of described pressure pipe, is threaded mutually with the one end of filtering body; Filter in body and be disposed with screen pack and activated carbon layer along the flow direction of cold-producing medium, the tapered shape of cross section of screen pack.

Further, between described retainer plate and filtration pipe end, be provided with sealing ring.

Further, described activated carbon layer directly over be provided with anion layer.

Adopt after said structure, the utility model beneficial effect is: the filter of a kind of air-conditioning refrigerant described in the utility model, comprise two copper pipes and filter body, one end of two copper pipes is closely nested in respectively in the connection chamber that filters body two ends, one end of two copper pipes is fixedly installed respectively and the retainer plate that filters pipe end and match mutually, and retainer plate one end face is compressing the termination of filtering body; Copper pipe is also nested with the pressure pipe matching mutually with retainer plate, after the nested retainer plate of inner chamber of described pressure pipe, is threaded mutually with the one end of filtering body; Filter in body and be disposed with screen pack and activated carbon layer along the flow direction of cold-producing medium, the tapered shape of cross section of screen pack.In the time using the utility model, can increase the filter area of screen pack, solve the defect of the sad filter of screen pack in the past, avoid impurity to stop up screen pack mesh; Be convenient to user simultaneously and regularly replace filtration body, thereby ensure efficiency and the quality of filtering, save the energy.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1-2, the filter of a kind of air-conditioning refrigerant described in the utility model, comprise two copper pipes 1 and filter body 2, one end of two copper pipes 1 is closely nested in respectively in the connection chamber 2-3 that filters body 2 two ends, one end of two copper pipes 1 is fixedly installed respectively and the retainer plate 4 that filters body 2 terminations and match mutually, and retainer plate 4 one end faces are compressing the termination of filtering body 2; Copper pipe 1 is also nested with the pressure pipe 3 matching mutually with retainer plate 4, after the nested retainer plate 4 of inner chamber of described pressure pipe 3, is threaded mutually with the one end of filtering body 2; In the time that filtration body 2 is installed, filtration body 2 is arranged on indoor, is convenient to like this user and regularly replaces filtration body 2, thereby ensure efficiency and the quality of filtering; Meanwhile, use this connected mode, can change fast and filter body 2.

As shown in the arrow in figure, filter the interior flow direction along cold-producing medium of body 2 and be disposed with screen pack 6 and activated carbon layer 7, cold-producing medium is after screen pack 6 filters, obtain comparatively pure cold-producing medium, this cold-producing medium is again through activated carbon layer 7 purified treatment, adsorb the assorted taste of cold-producing medium, thereby obtained clean cold-producing medium.

The tapered shape of cross section of screen pack 6; The filter area that can increase like this screen pack, solves the defect of the sad filter of screen pack in the past, avoids impurity to stop up screen pack mesh, can ensure the pressure in copper pipe 1, makes filter efficiency high, saves the energy.

As a kind of optimal way of the present utility model, between described retainer plate 4 and filtration body 2 terminations, be provided with sealing ring 5, can strengthen like this and filter body 2 and the sealing that copper pipe 1 is connected, avoid refrigerant external leakage.

As a kind of optimal way of the present utility model, directly over described activated carbon layer 7, be provided with anion layer 8; Clean cold-producing medium is processed through anion layer 8, can obtain healthy cold-producing medium, because the anion in anion layer 8 can be facilitated the synthetic and vitamin storage of human body, the physiological activity of strengthening and human activin, after thunderstorm, the anion of air increases, and it is happy that people feel.

In the time using the utility model, can increase the filter area of screen pack, solve the defect of the sad filter of screen pack in the past, avoid impurity to stop up screen pack mesh; Be convenient to user simultaneously and regularly replace filtration body, thereby ensure efficiency and the quality of filtering, save the energy.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
