Abstract
A modular air conditioning system comprises a self-contained refrigeration power cell, a heat exchanger remotely located from the refrigeration power cell, and a low pressure refrigerant communication circuit operably coupling the refrigeration power cell to the heat exchanger. 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. A drive mechanism, such as an electric or hydraulic motor, or conventional belt, is coupled to the compressor. The low pressure refrigerant communication circuit thermally interfaces with the condenser to remove heat from the high pressure closed refrigeration circuit. 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 an over-the-road or off-road vehicle. Preferably, a second heat exchanger and a second low pressure refrigerant communication circuit is included. This second circuit thermally interfaces with the condenser to remove heat from the refrigeration circuit.
