Etc. equipment required power consumption still less than the lowest power consumption of compressor, heat management system enters first circulation mode.It please join
Fig. 5 is read, in the first circulation mode of heat management system, compressor is closed, and the 4th valve member is closed, and the first valve member is closed, and pump is opened,
Third valve member and the second valve member are opened, and the company of the second port of First Heat Exchanger, the second port of pump, the second heat exchanger is opened
Road all, in first circulation mode, under the driving of pump, the coolant liquid of First Heat Exchanger and the second heat exchanger is realized to be handed over coolant liquid
It changes, the coolant liquid of First Heat Exchanger flows into the second heat exchanger in other words, and the coolant liquid of the second heat exchanger flows into first and changes in other words
Hot device, the coolant liquid all flowed out from First Heat Exchanger flow into the second port of the second heat exchanger through connecting pipeline.When battery etc. is set
Standby temperature is higher, needs to reduce the temperature of the equipment such as battery, and passenger compartment has heat demand at this time, if First Heat Exchanger is arranged
It is discharged into coolant liquid in the second heat exchanger of UTILIZATION OF VESIDUAL HEAT IN of the passenger compartment of air-conditioning box, the equipment such as battery, coolant liquid passes through communicating pipe
Road flows into First Heat Exchanger, discharges heat to passenger compartment, to improve the temperature of passenger compartment, is improved using the heat of the equipment such as battery
The temperature of passenger compartment is conducive to the energy for rationally utilizing heat management system.
When the temperature of the equipment such as battery is relatively high, needs to reduce the temperature of the equipment such as battery, and passenger compartment also needs
When freezing, heat management system enters second circulation mode, please refers to Fig. 6.In second circulation mode, compressor 4 is opened, and first
Throttling set 303 is opened, and pump 205 is opened, and refrigerant and coolant liquid are in the generation heat exchange of third heat exchanger；First valve member is closed,
Second valve member, third valve member and the 4th valve member are opened, in this way, heat management system controls that the 4th valve member opens third heat exchanger
The communication paths of the second port of the second port and pump of two runners, heat management system control third valve member and open First Heat Exchanger
Second port and pump second port communication paths, heat management system controls the first port and that the second valve member opens pump
The communication paths of the second port of two heat exchangers, the coolant liquid of relative low temperature enter the heat that the second heat exchanger absorbs the equipment such as battery
Amount, then respectively enters the second flow channel of First Heat Exchanger and third heat exchanger.Specifically, refrigerant by compressor compresses it
Become the gas of high temperature and pressure afterwards, the refrigerant of compressor discharge enters the 4th heat exchanger, and refrigerant is in the 4th heat exchanger and week
Air heat exchange is enclosed, surrounding air absorbs the heat of the refrigerant of the 4th heat exchanger and heats up, become the refrigerant of cryogenic high pressure,
Open first throttling device refrigerant after first throttling device throttles enter third heat exchanger first runner, refrigerant and
Coolant liquid is exchanged in third exchanger heat, the heat of refrigerant suction coolant liquid, and the coolant liquid after cooling flows under pump driving.
Coolant liquid after cooling enters the second heat exchanger, with the equipment heat exchange such as battery, reduces the temperature of the equipment such as battery, then part
Coolant liquid enters the second flow channel of third heat exchanger, and another part coolant liquid enters First Heat Exchanger and then reduces the temperature of passenger compartment
Degree in this way, can adjust the second flow channel flow for entering third heat exchanger by third valve member and the 4th valve member, and then adjusts electricity
The temperature of the equipment such as pond.In other embodiments, the second heat exchanger of heat management system be set to can with the air duct of air-conditioning box,
One heat exchanger is the coolant liquid device of the heat-producing devices such as battery；Or the second end of the first port of connecting pipeline and the second heat exchanger
Mouth connection, in this way, the coolant liquid of third heat exchanger outflow enters First Heat Exchanger, to adjust the temperature of passenger compartment.Or second

Form security risk, it is therefore desirable to dehumidify to passenger cabin air, i.e. the dehumidification mode of heat management system.Specifically, with Fig. 4
The dehumidification mode of heat management system is introduced, refrigerant becomes the gas of high temperature and pressure, compressor row by compressor compresses later
Refrigerant out enters the 4th heat exchanger, and the refrigerant of high temperature and pressure, which is controlled in the 6th heat exchanger around, discharges heat, and the 6th
The refrigerant of heat exchanger opens the first connector and the first flow control of first flow control device through first flow control device
The communicating passage of the third connector of device processed, first flow control device close the first connector of first flow control device
With the communicating passage of the second connector of first flow control device, the refrigerant after first flow control device reducing pressure by regulating flow becomes
For the medium of low-temp low-pressure, air of the refrigerant of low-temp low-pressure in the 5th heat exchanger and air-conditioning box carries out heat exchange, absorbs
The heat of surrounding air, since the temperature of the 5th heat exchanger surface is lower, the vapor in air understands condensation, air
By cool-down dehumidification, and the refrigerant for passing through the 5th heat exchanger enters the import of compressor by gas-liquid separator；To improve passenger
Comfort level opens pump, opens the communication paths of the second port of First Heat Exchanger and the second port of the second heat exchanger, closing the
Four valve members and the first valve member, absorb the coolant liquid of the equipment heat such as battery in the second heat exchanger and the air-flow heat exchange that is cooled down,
To improve the temperature of air-conditioning box interior air-flow, while also reducing the temperature of the equipment such as battery.
When passenger compartment temperature is higher, needs to reduce passenger compartment temperature to improve comfort level, heat management system enters refrigeration
The refrigeration mode of mode, heat management system includes the first refrigeration mode and the second refrigeration mode, in the first refrigeration mode, refrigerant
By becoming the refrigerant of high temperature and pressure after compressor compresses, the refrigerant of compressor discharge enters the 6th heat exchanger, refrigeration
Agent is exchanged with around with atmospheric heat in the 6th heat exchanger, is discharged heat to surrounding air, is become the refrigeration of relative low temperature high pressure
Agent, after the throttling of first flow control device, refrigerant enters the 5th heat exchanger, the refrigerant suction air-conditioning of the 5th heat exchanger
The heat of case interior air-flow, refrigerant is cooling in air of the 5th heat exchanger to surrounding in other words.In addition, when passenger compartment and battery etc.
Equipment be both needed to refrigeration when, heat management system enter the second refrigeration mode, open first flow control device the first connector with
The communicating passage of the third connector of first flow control device opens the first connector and first of first flow control device
The communicating passage of second connector of volume control device, some refrigerant after throttling enter the first-class of third heat exchanger
Road reduces the temperature of coolant liquid in the coolant liquid heat exchange of third heat exchanger and coolant system, the coolant liquid of cooling respectively into
Enter First Heat Exchanger and the second heat exchanger, to reduce the temperature of the equipment such as passenger compartment and battery respectively；Part refrigeration after throttling
