Cargo Van Refrigeration Unit Installation

Refrigeration Unit Installation mainly consists of three parts: Compressor, Condenser, Evaporator.

Compressor Installation

It is mounted to the vehicle engine with a compressor mounting bracket and is driven by the vehicle belt drive system. Refrigerant enters the compressor as a low-temperature, low-pressure gas. The compressor compresses the refrigerant and changes it to a high temperature, high-pressure gas.

Condenser Installation

Rooftop or Nose Mounted it receives the high temperature, high-pressure refrigerant from the compressor and through the process of heat exchange, assisted by the condenser fan motor, changes the state of the refrigerant to a high-temperature liquid. This change of state takes place when the air circulating around the tubing and fins of the condenser coil, cools the refrigerant.

Evaporator Installation

It is located in the cargo area of the vehicle. The liquid refrigerant entering the evaporator via the expansion valve is thermostatically controlled to change state from a liquid to a low pressure, low-temperature gas. The refrigerant now absorbs the heat from the cargo area by passing air over the evaporator coil assisted by the evaporator fan motor. At this point, the refrigerant is referred to as a “saturated mixture” in the evaporator coil. When this process is complete, the gas returns to the compressor as a low temperature, low-pressure gas, and this entire process is repeated until the desired temperature is reached.
