Key components:
1. Compressor: Drive R134a coolant flow
2. R134a to water Plate heat exchanger ：
3. Electronic expansion valve 1：Control R134a refrigerant circulation flow
4. R410a to R134a Plate heat exchanger ：Heat transfer between R410a and R134a refrigerants
5. Electronic expansion valve 2：Control the R410a coolant flow of the hydraulic module
