As the main equipment of modern cold chain logistics, the working performance of truck refrigeration unit is directly related to the quality and safety of food, medicine and other temperature-sensitive goods.

I. THE BASIC COMPOSITION OF REFRIGERATED TRUCK REFRIGERATION UNIT
Refrigerated truck refrigeration system is mainly composed of the following key components:

1.1,Compressor: the heart of the system, responsible for compression and circulation of refrigerant
1.2. Condenser: high temperature and high pressure gaseous refrigerant cooled to liquid state
1.3. Expansion Valve: controls the flow of refrigerant and reduces the pressure
1.4. **Evaporator**: Absorbs heat from the compartment and cools it down.
1.5. Control system: monitoring and regulating temperature, humidity and other parameters
1.6. Fan system: promote air circulation, ensure uniform temperature

Common Issues and Quick Troubleshooting Guide For Truck Refrigeration Unit and Parking Air Conditioner

COLDCHAIN refers to special supply chain systems. Perishable food products are processed, stored, transported, distributed and retailed from the point of acquisition or harvesting at the point of origin until they reach the consumer, where they are kept at the low temperatures necessary for the product to be of good quality.

This guide is about how to install a truck refrigeration unit when you receive the package. We talk about the installation mainly from these parts: preparation before installation，condenser Installation，evaporator Installation，compressor Installation，connecting pipeline，vacuuming and pressurizing，connecting and sealing，filling refrigerant and the trial and test.

In an era where consumer demand for fresh, high-quality food is at an all-time high, the journey of goods from farm to table has never been more critical. The success of this journey depends on an efficient and reliable supply chain, and one of the key contributors to this process is the transport refrigeration units. These specialized systems play a pivotal role in ensuring that perishable goods maintain their quality and freshness from the moment they leave the farm to when they arrive at your local grocery store—or even your own kitchen. Sinoclima is committed to ensuring the freshness of goods.

When selecting refrigeration units for trucks, factors such as the volume of the compartment, the temperature requirements of the goods to be transported and the transportation mileage should be taken into account. Next let me make a specific introduction.
