The design and performance of the refrigeration unit of a refrigerated truck is important to ensure that goods are transported or stored at the appropriate temperature. It usually includes the following components:
- Compressor: The compressor is the core component of the refrigeration system and is responsible for compressing and pumping the refrigerant.
- Condenser: The condenser is used to release the heat of the refrigerant into the outside air, causing it to cool and become a liquid.
- Evaporator: The evaporator is located inside the cargo hold and is responsible for absorbing heat in the cargo area and evaporating the refrigerant into a gaseous state.
- Expansion Valve: The expansion valve controls the refrigerant from the high-pressure area to the low-pressure area to achieve the cooling effect.
- Control System: The control system monitors and regulates the operation of the refrigeration unit to ensure that the goods remain stable within the required temperature range.
Refrigeration units are divided into independent units and non-independent units
Self-contained Refrigeration Unit
The refrigeration unit is completely independent of other systems of the vehicle or container and does not rely on the vehicle’s engine or power source. It contains all necessary components such as compressor, condenser, evaporator and control system.
Non-Self-contained Refrigeration Unit
This refrigeration unit relies on an external power source or vehicle engine for power. It usually does not have its own engine and generator. This design may limit the flexibility of the refrigerated truck because it requires external power support and may be affected by the state of the vehicle’s engine.
