PURPOSE:To enable the cold insulation transportation of a small sized vehicle by making the evaporator of the cooling unit equipped with the compressor driven by the main engine for traveling the heat exchanger for cooling the air inside a container chamber in the cold insulation vehicle transporting a fresh fish, etc. CONSTITUTION:The refrigerant gas discharged from the compressor 5 which is driven by a vehicle engine 3 is returned to the compressor 5 via a condenser 7, an expansion valve 8 and a pressure adjusting valve 10 and a primary cooling unit 6 is made. On the other hand, the secondary cooling unit 11 taking a brine as a secondary refrigerant is provided at the front part of a container 2, the brine is circulated to the evaporator 9 side of the primary cooling unit 6 and the cooling is executed by the heat exchanger with the primary cooling unit. The air cooled by the unit 11 is fed to a cold insulation box 18 via a dust 15, discharging port 17 and hose 20 and circulated by coming out of an outlet port 121. A cold insulation transportation is thus enabled by a small sized vehicle. |
