ABSTRACT:
An air-conditioning system embodiment for temperature control in a vehicle comprises heater cores, controllably connected to a coolant contour, outletting the conditioned air towards a person sitting in a chair, or into a food compartment. Some cores are mounted inside of chairs' backs situated in front of rear passengers, other cores are mounted in the chair back and inside the chair seat. A refrigerant-coolant heat exchanger provides heat exchange between a refrigerant contour and the coolant contour, cooling the coolant supplied to the cores. A refrigerant compressor is driven by a hydraulic motor, operated by pressurized oil delivered through a hydraulic contour from a first hydraulic pump driven by the vehicle's engine connected to the first pump through an electromagnetic clutch, or alternatively from a second hydraulic pump driven by a substitute engine, connected to the second pump through another electromagnetic clutch, both clutches are controlled by a thermostat.
