Let's learn about it together with the refrigeration machine editor.

（1） What to pay attention to when cleaning refrigerated carriages

1. Seize the time

It is recommended to clean the goods after unloading the refrigerated compartment, so that the air refrigerated compartment is easy to clean and saves time and effort. Clean immediately after use and do not delay at any time. Residual stains will be more difficult to remove in the future.

2. Selection of cleaning tools

It is very important to know what tools we need to use to clean refrigerator cars. We know that refrigerator cars are generally clean and shiny, and the tools used will not cause scratches or other damage to the refrigerator car. Therefore, soft materials and non corrosive cleaning agents are used.

3. Treatment after cleaning

When organizing work, also pay attention to cleaning. Do not leave water or footprints inside the refrigerator car, especially in the sandwich refrigerator car, to avoid deformation or rust. After the cleaning work is completed, open the car body, close the car door, and let it dry.

（2） Classification and composition of refrigerated carriages

1. The refrigerated compartment is mainly composed of components such as the car chassis, insulation, refrigeration unit, and in car temperature recorder. For vehicles with other requirements, such as meat hook car, meat hook, waist, aluminum alloy guide rail, ventilation duct and other optional components.

2. Refrigerated compartment body: generally composed of polyurethane materials, fiberglass, color steel plates, stainless steel, etc. The production process includes: split assembly sandwich panel bonding type, split assembly injection foaming type, integral skeleton injection foaming type, vacuum adsorption paste, etc.

3. Refrigerated compartment refrigeration unit: The refrigeration unit is divided into non independent refrigeration unit and independent refrigeration unit. Domestic units, imported units, etc. General car models use external refrigerators, while a few micro refrigerated compartments use internal refrigerators. For refrigerated compartments with lower temperature requirements, refrigerated panels inside the vehicle can be used.
