The air conditioning system of Chongqing refrigerated trucks mainly uses fluorine as the medium to achieve refrigeration by changing the system pressure. It consists of an evaporator, an expansion valve, a compressor, a blower, a condenser, a drying oven, and pipelines. When the air conditioning system is working normally, the evaporator operates in a cold environment, and the opposite hot air produces water.

These odors will mix with the air conditioner during its operation. The interior of the vehicle often makes the driver feel uncomfortable. Severe cases can cause discomfort such as dizziness and chest tightness.

It is commonly referred to as air conditioning disease. In order to solve this problem in the maintenance industry, it is often necessary to disassemble the evaporator and clean the surface of the evaporator to achieve the goal of fundamentally removing odors.

However, each disassembly requires a series of processes, such as fluorine installation and addition, which are cumbersome, technically difficult, and inefficient. Because the evaporator box usually works in a humid environment and is prone to mold growth, the air conditioner that has just removed the mold may produce an odor over time.

In addition, common problems in the air conditioning system of refrigerated trucks are poor heat dissipation and small leaks of fluorine, which pose great difficulties for maintenance. In the air conditioning system, the power of fluorine circulating in the air conditioning pipeline comes from the compressor, and the lubrication of the compressor is completed by fluorine oil.

In the pipeline, fluorine oil and fluorine circulate throughout the system, and their circulation flow directly affects the refrigeration performance of the air conditioner. For a long time, fluorine and fluorine oil in environments with high temperature and high pressure, low temperature and low pressure have been constantly changing, so compressors have become increasingly popular.

Metal fragments such as long-term wear and tear can produce deposits such as colloids. Some of these sediments are filtered out, and some of them are deposited in various pipelines. A small amount of sediment will not affect the cooling performance of the air conditioner, but it will produce sediment.

More and more substances will affect the circulation flow of fluorine, and the air conditioning of refrigerated trucks will still be poorly cooled due to factors such as fluorine and fluorine. Refrigerated truck manufacturers may consider whether they can solve the cleaning problem in the air conditioning system.
