Compression stage
The electric-driven compressor compresses the gaseous refrigerant into high-temperature and high-pressure gas
Compared with traditional idling air conditioners, electric compression reduces engine wear and carbon deposit risks
Condensation and heat dissipation
The high-temperature refrigerant enters the condenser and is forced to cool by the cooling fan and converted into a medium-temperature and high-pressure liquid
Heavy-duty trucks mostly use a top-mounted condenser design to enhance heat dissipation efficiency by using the driving wind
Throttling and pressure reduction
The liquid refrigerant is reduced in pressure by the expansion valve and becomes a low-temperature and low-pressure mist mixture8
Evaporation and heat absorption
The refrigerant absorbs the heat in the cab in the evaporator to achieve air cooling (as low as 18°C)
