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.

What kind of information is needed to make the right choice? Choosing a transport refrigeration unit depends on many factors. All this information should be provided before ordering the unit.

Internal and external lengths of the truck bodies.
Internal and external width of the truck bodies.
Internal and external height of the truck bodies.
Ambient temperature.
Temperature required inside compartments.
Products to be transported.
Number of door openings
K factor of the body
Road operation and/or standby operation,
Type of use (long-distance transport, local distribution, etc.).
Other useful information.
