Conclusion is the title. Be aware to turn off the transport refrigeration unit while loading and unloading is crucial. Before explaining the reason, Corun wants to talk about precooling first, which all drivers of refrigerated vehicles should know.

Refrigerated vehicles usually stop at roadside and wait for goods, so the temperature of the container is close to the ambient temperature. If the vehicle is not precooled, the goods transported are likely to be damaged because of inappropriate temperature. How to precool? Set the temperature controller at desired temperature and let the unit cool to discharge heat inside the container, so that when goods are loaded, the temperature inside is suitable and even across the container. Precooling time depends on the desired temperature and the cooling capacity of the unit. Desired temperature is certain and we cannot change that, so what we can do is finding a unit with good performance. Choose the right unit can save precooling time and save money. Advertisement time: Corunclima has ideal transport refrigeration units, chiller or freezer up to you, for various vehicles, from 2.5-3.5m3 mini-size van, 6-12m3 mid-size van, 16m3 big-size van, 5-6m3 pickup, to 12-55m3 trucks.

Come back to today's topic. In fact, many drivers tend to let the transport refrigeration unit run when loading and unloading goods, thinking that in this way the temperature can be kept without being influenced by outside hot air. This is wrong.

If the transport refrigeration unit continues to run while loading and unloading, when the door is opened, the evaporator will continue to blow out the cold air and inhale hot air from the outside, causing rapid increase of the temperature in container. If the transport refrigeration unit is stopped while loading and unloading, the evaporator is stopped and will not speed up the air circulation. The speed for outside hot air going into the container is lowered a lot.

Together with Corunclima, let's enjoy the comfort brought by worry-free transport refrigeration unit and air-conditioning system for trucks, vans, and various types of vehicles!
