Heat pump is configured to circulate refrigerant flow for cooling/heating function.
This process minimizes battery consumption by the heater resulting in enhanced driving distance of EV.
[Heating]
1.
Outer Condenser - Evaporates liquid refrigerant and forms low temp-low pressure gas substance.
2.
3-Way Solenoid Valve #2 - Redirects the refrigerant direction towards the chiller when heat pump is active.
3.
Chiller - Uses waste heat from the motor and performs secondary heat exchange on low temp-low pressure gas.
4.
Accumulator - Separates gas/liquid so that only the refrigerant in gas state can flow into the compressor.
5.
Electric Compressor - Compressor is operated by electric
motor. Converts low temp-low pressure gas refrigerant into high
temp-high pressure gas and sends it to inner condenser.
6.
Inner Condenser - Condenses high temp-high pressure gas
refrigerant and transforms it into high temp-high pressure liquid
refrigerant.
Evaporator - Operates blower fan to cool the air passing
through the evaporator pin while the refrigerant in foggy state is
transformed into gas (surrounding area gets cold).
5.
Accumulator - Separates gas/liquid so that only gas state refrigerant can flow into the compressor.
6.
Electric Compressor - Compressor is operated by electric
motor. Converts low temp-low pressure gas refrigerant into high
temp-high pressure gas and sends it to inner condenser.
7.
Inner Condenser - Condenses high temp-high pressure gas
refrigerant and transforms it into high temp-high pressure liquid
refrigerant.
8.
2-Way Solenoid Valve #1 - Does not expand but circulates refrigerant when A/C is operating.
9.
2-Way Solenoid Valve #2 - Prevents refrigerant from flowing into evaporator.
10.
3-Way Solenoid Valve #1 - Circulates refrigerant to outer condenser.
Description
Charge port consists of normal charge port (1) and the rapid
charge port (2) in the front of vehicle. The charge starts when the ICCB
or the quick charge coonnector is connected to charge port.
