When the compressor is operating, the compressor draws in the low-temperature, low-pressure gaseous refrigerant from the evaporator, and after compression, the temperature and pressure of the refrigerant rises and is sent to the condenser. In the condenser, the high-temperature and high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser to be liquefied and turned into a liquid. As the liquid refrigerant flows through the throttling device, the temperature and pressure are reduced and enter the evaporator. In the evaporator, the low-temperature low-pressure liquid refrigerant absorbs heat from the air inside the evaporator and evaporates to become a gas. The gas is again drawn into the compressor for the next cycle. In this way, through the circulation of the refrigerant in the system, the heat of the air inside the vehicle is continuously absorbed and discharged into the air outside the vehicle, so that the temperature of the air inside the vehicle gradually decreases.

The No Idling Truck air conditioner, powered by a DC12 / 24V car battery, ensures that it will work when the engine is off. The sleeper air conditioning condenser assembly is mounted on the roof or exterior rear wall of the nacelle with an air outlet plate (or evaporator) installed to facilitate installation according to vehicle conditions and personal preferences. This installation design for battery-powered air conditioners for trucks provides maximum flexibility. It has digital display automatic control system, automatic temperature control, automatic fault diagnosis, reliable control, easy maintenance and maintenance. In addition, it has a streamlined ultra-thin design, with good corrosion resistance, weather resistance, UV resistance and anti-aging characteristics, while saving fuel and noise, providing a comfortable and cool experience.
