Abstract
An apparatus includes a first expander, a flash tank, a first load, a first work recovery compressor, a valve, and a first compressor. The first expander expands a refrigerant. The flash tank stores a refrigerant from the expander. The first load uses the refrigerant from the flash tank to cool a space proximate the first load. The work recovery compressor compresses the refrigerant from the first load and is driven by the first expander. The valve reduces the pressure of the refrigerant from the work recovery compressor below a threshold. The first compressor compresses the refrigerant from the valve.
