Specific work process of the present embodiment under each middle operating condition is described in detail below.
The first situation: in summer high temperature, battery pack and crew module only have refrigeration demand, and air-conditioning system is to make
Cold mode operation, refrigerant circuit are divided into two branch operations, and respectively crew module and battery provides refrigeration.Motor cooling circuit
It is independently run with battery cooling circuit, crew module's coolant circuit stops working.Specific works pipeline such as dotted line institute in Fig. 2
Show, at this point, the first solenoid valve 17 is opened, second solenoid valve 18 is closed, and the first triple valve 8 is connected to a, the end b, the first electric expansion valve
19 and second electric expansion valve 20 respectively as the second evaporator 16 of crew module and the throttle valve of battery cooler 14 according to each
Normally decide whether to enable from demand.The third water pump 21 of crew module's coolant circuit does not work, and entire coolant circuit is closed.
Third triple valve 11 is connected to the end h, i, battery coolant circuit isolated operation.Second triple valve 10 is connected to the end d, e, motor coolant liquid
Circuit isolated operation.
The course of work at this time are as follows: the high temperature and high pressure gas come out from air compressor 15 successively passes through the first condenser 5
It is divided into two-way with after the second condenser 9, passes through the second evaporator 16 all the way, to freeze to crew module, another way is by electricity
Pond cooler 14 is back to air pressure after then carrying out gas-liquid separation after gas-liquid separator 4 to cool down to battery pack 3
Contracting machine 15 is recycled.
Second situation: season in spring and autumn, temperature do not need to cool down between 10~20 DEG C (TBD), crew module, do not need to add yet
Heat, motor needs to cool down at this time, and battery also has cooling requirement, since ambient temperature is not high, so the cooling requirement of the two is equal
Cooling can be carried out by the cooling water tank 12 in motor cooling circuit.Service pipe at this time is as shown in phantom in Figure 3.It is empty
Air compressor 15 does not work, and entire refrigerant circuit does not work.Second triple valve 10 is connected to the end d, e, and third triple valve 11 is connected to

Pipeline, the second triple valve 10, the first evaporator 1 first passage after be back to the second water pump 6.In which, in electric motor loop
Heat by the first evaporator 7 exchange heat into refrigerant circuit.The coolant liquid independent operating of cell circuit at this time.
When battery temperature is higher, the coolant liquid in cell circuit can also be switched to the first passage of the first evaporator 1
Middle carry out heat exchange, specific works pipeline is as shown in dotted portion in Fig. 8.At this point, the work of electric motor loop and refrigerant circuit
Mode is identical with state shown in Fig. 7, the working method of cell circuit are as follows: third T-way water valve 11 is connected to the end g, h, the first water
2 work of pump, the first electric heater 13 do not work.In cell circuit coolant liquid successively pass through the first water pump 2, battery cooler 14,
Cooling pipe, third triple valve 11, the second triple valve 10 at battery pack 3 are back to after the first passage of first evaporator 1
In one water pump 2.
When in winter, the present embodiment exchanges the heat that motor and/or battery generate into refrigeration system, takes full advantage of
The heat that motor and/or battery generate, improves the utilization efficiency of the electricity of vehicle.When using motor and/or cell circuit
When heat is as heat source, the efficiency of heat pump can be significantly hotter than the heat pump system using air as heat source.In addition, in proper temperature
When, it is radiated simultaneously to battery and motor using cooling water tank, is not required to additionally start compressor, cost saved electricity
