A transport refrigeration unit
is a device used to keep the temperature
of goods in transit stable and is usually installed on a transport vehicle. It is composed of a compressor
, control system
, etc., and realizes cooling or heating of goods by circulating refrigerant
to maintain the temperature range of goods required during transportation.
The transport refrigeration unit is mainly used for cooling or refrigeration. Its working principle is to use the compressor to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, and then transfer the heat to the environment through the heat exchanger to cool the refrigerant or form low temperature.
Its function is to remove heat from the goods through the refrigeration cycle system, keep the goods at the required low-temperature state, and prevent the goods from deteriorating or being damaged. This type of equipment is often used for long-distance transportation of food, pharmaceuticals, chemicals, and other temperature-sensitive goods. Provide the compartment with a set temperature in order to achieve the temperature required to hold the cargo.
Transport refrigeration units can be divided into truck refrigeration units
and van refrigeration units
according to the type of vehicle, and can be divided into pure electric drive
, engine direct-drive
, and diesel engine drive
according to the driving mode.
