Description of drawings
Fig. 1 is the electrical structure schematic diagram of electric motor car cold and heat air adjusting device of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, electric motor car cold and heat air adjusting device of the present utility model, it comprises: air-conditioner controller (or claiming the A/C switch) 1, compressor controller 2, electric air-conditioning compressor 3, cross valve 4, condenser 5, drier (or claiming drying chamber) 6 and evaporimeter 8.This air-conditioner controller comprises: processor, air-conditioning gauge tap and heat switch.
Concrete annexation is: air-conditioner controller 1 is electrically connected with the signal input part X of compressor controller 2 and cross valve 4 respectively, and the control output end of compressor controller 2 is electrically connected with the control input end of electric air-conditioning compressor 3.Cross valve of the present utility model is existing cross valve, and this cross valve has electric signal input end X(control coil), air inlet D, middle gas outlet S and be positioned in the middle of left end gas port C and the right-hand member gas port E of gas outlet both sides.The gas outlet of electric air-conditioning compressor 3 is connected with the air inlet D of cross valve 4, the middle gas outlet S of cross valve 4 is connected with the return-air mouth of electric air-conditioning compressor 3, the left end gas port C of cross valve 4 is connected with first gas port of condenser, second gas port of condenser is connected with first gas port of drier 6, the right-hand member gas port E of cross valve 4 is connected with first gas port of evaporimeter 8, and second gas port of evaporimeter 8 is connected with second gas port of drier 6.
During concrete work, when needs freeze: press the air-conditioning gauge tap in the air-conditioner controller, adjust corresponding cryogenic temperature, air-conditioner controller is by 3 runnings of compressor controller 2 control electric air-conditioning compressors.Refrigerant trend (by accompanying drawing heavy line and filled arrows shown in) has formed kind of refrigeration cycle successively by electric air-conditioning compressor 3, cross valve air inlet D, cross valve left end gas port C, condenser 5, drier 6, evaporimeter 8, cross valve right-hand member gas port E, cross valve centre gas outlet S, flow into the electric air-conditioning compressor at last.
