Let's talk about the transportation of perishable foods in refrigerated trucks, which can easily cause odors in the cabin. In addition, when the refrigeration unit of a refrigerated truck is in normal working condition, it is easy to produce water when exposed to hot air from the outside. The evaporator and ventilation ducts are relatively humid and accumulate dust on the surface. These odors will be emitted as the refrigeration unit of the refrigerated truck is turned on, polluting the entire cabin and affecting the goods.

The repair industry generally solves the problem of odor in refrigerated trucks by disassembling and cleaning the evaporator. This method requires high technical requirements, and every time it is disassembled and cleaned, a series of steps such as adding fluorine, installing, and adding fluorine are needed, which is troublesome and does not have a fundamental effect.

Even if it's okay, it's temporary. After running for a period of time, microorganisms can still grow as usual because the moisture and dust in the evaporator ventilation duct itself are a breeding ground for microorganisms. That's the real reason why the newly cleaned refrigeration unit of the refrigerated truck has a smell again.

In the refrigeration unit system of refrigerated trucks, fluorine circulates in the refrigeration unit pipeline, and the power mainly comes from the compressor. The lubrication of the compressor is completed by fluorine oil.

In the pipeline, fluorine oil and fluorine circulate together in the entire system, and its circulation flow directly affects the refrigeration performance of the air conditioner. Fluorine and fluorine oil are constantly changing in high temperature, high pressure, and low temperature and low pressure environments for a long time. In addition, metal debris caused by the long-term wear and tear of the compressor will produce deposits such as gum. Some of these deposits are filtered out and some settle in various pipelines. A small amount of sediment does not affect the refrigeration performance of the air conditioner, but the continuous increase of sediment will affect the circulation flow of fluorine. Therefore, due to factors such as fluorine, the refrigeration performance of the refrigerated car air conditioner is still poor. We may consider whether the air conditioning system is clean, and the problem may be easily solved.
