<p>An air conditioning system for a vehicle. The system includes a boiler that converts a motive refrigerant from a liquid state to a vapor having a motive pressure and motive temperature. An evaporator positioned to transfer heat from the cabin to a working refrigerant. An ejector is configured to mix the motive refrigerant and the working refrigerant so that the motive refrigerant becomes part of the working refrigerant. A condenser transfers heat from the working refrigerant exiting the ejector to an area outside the cabin. A variable speed electrically powered compressor is provided to raise the pressure of the working refrigerant in order to improve the efficiency of the ejector.</p> |
