Detailed description of the invention
With detailed description of the invention, this utility model is further elaborated below in conjunction with the accompanying drawings.
As it is shown in figure 1, refrigeration air-conditioner multi-functional maintenance trolley refrigerant recovery system includes refrigerant-recovery bottle 1.It is connected with refrigerant-recovery bottle 1 pipeline and has condenser 2, described refrigerant-recovery bottle 1 is provided with liquid level mirror 5, the pipeline between described refrigerant-recovery bottle 1 and described condenser 2 is provided with recovered liquid mirror 11 and recovery valve 10.External recovery valve 9 it is provided with on pipeline between described recovered liquid mirror 10 and described condenser 2.Refrigerant-recovery bottle 1 is provided with the first fill valve 6, between the first fill valve 6 and refrigerant-recovery bottle 1, is provided with the second fill valve 16, between described first fill valve 6 and the second fill valve 16, be provided with filling filter 17.Described refrigerant-recovery bottle 1 is provided with emptying needle-valve 21 and blowdown needle-valve 22.
Condenser 2 pipeline is connected to the outlet of compressor 3 by oil eliminator 14.
Inlet valve 13 it is provided with on the entrance of compressor 3.It is provided with filter by suction 15 on pipeline between described compressor 3 and described inlet valve 13.The entrance of described compressor 3 is provided with vacuum meter 20.Described oil eliminator 14 is provided with needle-valve 18 of draining the oil.
As shown in Figure 2; also include circuit control system; described circuit control system includes switch 41 and the pressure controller 7 being sequentially connected with external power supply; switch 41 is connected with pressure controller 7; one end of pressure controller 7 is connected with compressor 3 through overheat protector 42, and compressor 3 is activated device 43 and is connected with the other end of pressure controller 7.Output at pressure controller 7 is connected to fan 44 repeatedly, and fan 44 is facing to condenser 2.
As shown in Figure 3 to Figure 4, corresponding Awaiting Overhaul equipment and the multi-functional maintenance trolley of refrigeration air-conditioner can be connected by a threeway maintenance valve 24 and realize the recovery of cold-producing medium, particularly as follows:
