It relates to a cooling system for a refrigerated vehicle using

The vehicle cooling system by the operation of the compressor mounted on the engine increases the load on the engine when the air conditioner is running, so fuel consumption generally increases by 20-30%. In the case of cooling, additional fuel consumption occurs because the air conditioner must be operated after the engine is started.

Recently, there is a technology that operates a refrigeration cycle by driving a DC electric compressor with battery power when the engine is off. there is a problem.

In the case of a refrigeration tower vehicle, a technology for cooling the loading box by supplying cold air from the cooling tank installed on the ground to the cooling tank installed in the vehicle through a brine has been proposed. However, in the case of heating and cooling in the driver's seat of a vehicle, additional costs and fuel consumption are incurred for the installation of the heating and cooling system.
