An air conditioning system is provided with mainly an evaporator, a compressor, a condenser and an energy recovery device. The compressor is fluidly connected to the evaporator to compress low-pressure refrigerant exiting the evaporator to high-pressure refrigerant. The condenser is fluidly connected to the compressor to receive the high pressure refrigerant and dissipate heat therefrom. The energy recovery device is configured to extract work from refrigerant flowing therethrough. The energy recovery device includes a movable expander and a valve. The movable expander has an inlet fluidly connected to the condenser to receive high pressure refrigerant exiting the condenser, an outlet fluidly connected to the evaporator to deliver low pressure refrigerant thereto and a chamber fluidly connected between the inlet and the outlet. The valve is configured to control a flow rate of high pressure refrigerant flowing from the inlet to the chamber. |
