Abstract:
An air-conditioning system for a motor vehicle having an exhaust pipe dispensing engine exhaust gas, the air-conditioning system comprising:a container for containing a liquid coolant,a heat exchanger connected to the container and associated with the exhaust pipe so the exhaust gas vaporizes the coolant,a pump for driving the coolant from the container through the heat exchanger,a jet device having a side opening and incorporating a nozzle adjacent to the side opening of the let device for producing a jet of a first part of the coolant supplied from the container and passing through the nozzle, thereby creating a negative pressure, due to the venturi effect, at the side opening of the jet device, andan evaporator having an inlet supplied with a second part of the coolant from the container, a side opening connected to the side opening of the jet device for application of the negative pressure to the evaporator, and an outlet, the second part of the coolant evaporating in the evaporator to produce a cooling effect for cooling air supplied into a cabin of the motor vehicle having the exhaust.
