The refrigeration system is operable to maintain the air temperature within a desired temperature range selected for the particular type of perishable object being stored in the cargo box within the enclosed space. The refrigeration system includes a refrigeration unit including a refrigerant compressor and condenser disposed outside of the cargo box and an evaporator disposed in the enclosed space of the cargo box. A compressor, a condenser and an evaporator are connected in a refrigerant circuit in a serial refrigerant flow relationship in a refrigeration cycle. When the refrigeration system is in operation, air is drawn from the enclosed space, through an evaporator disposed in the enclosed space in heat exchange relationship with the refrigerant circulating through the refrigerant circuit to be cooled, and then back to the enclosed space.
