What are the common classifications of van refrigeration unit (truck refrigeration unit)?

Truck chiller units are mainly divided into electric refrigeration unit, direct drive refrigeration unit and independent diesel powered refrigeration unit according to the driving mode.
1. Electric Refrigeration Unit: It is a refrigeration equipment powered by the vehicle battery. It has the characteristics of high efficiency, energy saving and environmental protection. Cooling operation can still be maintained when the vehicle is parked.
Recommended scenarios: vans and trucks with smaller compartments, or pure electric vans and pure electric trucks. Have awareness or requirements for environmental protection and energy conservation.
2. Direct Drive Refrigeration Unit: Its power source is the vehicle engine. It operates via a belt-driven compressor connected to the vehicle’s engine. It is characterized by low price, strong cooling capacity and long cooling time. No entanto, the engine must be running all the time and cannot be cooled when stopped.
Recommended scenarios: Vehicle transportation situation with short parking time or non-stopping. Budget is limited.

3. Diesel Powered Refrigeration Unit: It is equipped with an independent diesel engine and does not need to rely on the vehicle’s engine. So it can still be used when parking. It is characterized by higher independence, stronger cooling capacity, and wider applicable scenarios. But the price is relatively more expensive.
Recommended scenarios: Concerned about the refrigeration effect or the vehicle transportation situation is complex and changeable. Sufficient budget.

Tip: The selection of product models will be judged based on the vehicle type, ambient temperature, and transported goods. It is recommended that you contact our truck refrigeration unit manufacturers sales team and we will recommend the most suitable truck freezer unit for you.

How do van refrigeration units work？

The working of the van refrigeration unit (truck refrigeration unit) are as follows:
1. Processo de compressão: The compressor of the refrigeration unit will inhale low-temperature and low-pressure refrigerant gas from the evaporator. It is then compressed into a high temperature and high pressure gas and discharged.

2. Heat dissipation process: Then the high-temperature and high-pressure refrigerant gas enters the condenser. Due to the reduction in pressure and temperature, the refrigerant gas condenses into a liquid and removes heat.

3. Processo de limitação: The refrigerant liquid with higher temperature and pressure becomes larger in volume after passing through the expansion valve, the pressure and temperature drop sharply, and is discharged in the form of mist.

4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is lower than the temperature in the evaporator, the refrigerant liquid evaporates into gas. During the evaporation process, the surrounding heat is absorbed, and then the low-temperature and low-pressure refrigerant vapor enters the compressor. Repeatedly, the purpose of lowering the temperature inside the car is achieved.

How to maintain van refrigeration unit (truck refrigeration unit)?

1. Check the refrigerant charge regularly and keep it within the normal range.
2. Clean the condenser and evaporator to remove dirt and dust.
3. Check the electrical system to ensure it is normal and fault-free.
4. Check the compressor and pay attention to leakage, wear, looseness and other problems.
5. Keep the environment clean and dry to avoid moisture and dirt affecting performance.
