Description
Technical field
The utility model relates to air-conditioning production technical field, particularly relate to a kind of can the refrigerant filling system of timely emptying combustible refrigerant.
Background technology
At present, for the consideration to environmental protection pressure, all accelerating to eliminate cold-producing medium R22 ozone layer being had to destruction in worldwide, and substituting the cold-producing mediums such as R134a, R410A, R407C of R22, due to the chamber effect potential value GWP that it is high, also will face by the destiny of control (eliminating); Thereupon, the superior cold-producing medium of some environmental-protecting performances such as R32/R290 etc. starts to apply on domestic air conditioner, and the safety problem that the shortcoming of cold-producing medium R32/R290 is mainly caused by its combustibility, therefore in the domestic air conditioner production process using combustible refrigerant, drain at the combustible refrigerant filled and technique scene, sealing post must may be leaked in time, guarantee that in air, the content of combustible refrigerant is in a safe condition particularly important.Existing domestic air conditioner cold-producing medium R22, R410A etc. are non-combustible refrigerant, and to occur that electrostatic spark even adopts naked light to weld etc. be also foolproof filling with sealing technique scene, post.The air-conditioner adopting combustible refrigerant in process of production, must increase leakage of refrigerant emptier, and by filling, the combustible refrigerant leaked in on-the-spot air with sealing process is emptying in time, guarantees security.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of can the refrigerant filling system of timely emptying combustible refrigerant.
In order to realize above object, the technical solution adopted in the utility model is:
A kind of can the refrigerant filling system of timely emptying combustible refrigerant, comprise supercharging device, fill machine and master control box, also comprise cold-producing medium emptier, described cold-producing medium emptier comprises workbench for charging refrigerant and emptying blower fan, described workbench is the body structure of hollow, its table top and two sides are provided with the sieve aperture being with removable cover, for the cold-producing medium that suction is leaked; The inlet side of emptying blower fan is connected with the hollow layer of work top inside, for making the generation of workbench inside for the negative pressure of suction agent.
Further, also include the blast detector whether normally run for detecting emptying blower fan, and for detecting the gas concentration detector surveying the refrigerant concentration leaked; When blast detector detector detects that emptying blower fan does not normally run, master control box is closed supercharging device, is filled machine and emptying blower fan; When the refrigerant concentration that gas concentration detector detects in air is too high, master control box closes pressure device and filled machine.
Preferably, described emptying blower fan is the anti-riot pipeline fan of axial flow.
Further, the table top both sides of described workbench are provided with angle steel, and connecting with workbench side of described angle steel, its another side exceeds the table top of workbench, to form the chute that can slide for removable cover.
The beneficial effects of the utility model are: of the present utility model can the refrigerant filling system of timely emptying combustible refrigerant, comprise supercharging device, the machine of filling, master control box and cold-producing medium emptier, cold-producing medium emptier comprises workbench for placing air-conditioner to be filled and emptying blower fan, wherein table surface and its two sides offer the sieve aperture being with removable cover, when carrying out charging refrigerant, air-conditioning is placed on the enterprising line operate of sieve aperture of work top, emptying blower fan is utilized to produce negative pressure by emptying for the refrigeration machine leaked in filled process, guarantee production safety.
