  • Modular low-pressure delivery vehicle air conditioning system having an in-cab cool box
    Patent number: 6457324
    Abstract: A modular air conditioning system comprises a self-contained refrigeration power cell and a remotely located heat exchanger coupled by a low-pressure refrigerant circuit. The refrigeration power cell comprises a compressor, a condenser, an expansion device, and an evaporator, which are serially coupled to form a high-pressure closed refrigeration circuit. The low-pressure circuit thermally interfaces with the condenser to remove heat from the high-pressure circuit. This heat exchanger is adapted to mount in proximity to or be integrated with the radiator. Alternatively, this circuit thermally interfaces with the evaporator to remove heat from the low-pressure refrigerant. This heat exchanger is adapted to mount in the cabin of the vehicle. When the low-pressure circuit thermally interfaces with the evaporator, the low-pressure circuit may further include a cool box for storing items to be refrigerated. Preferably, the cool box and heat exchanger may each be operated either alone, or in combination.
