Abstract
An apparatus includes a first expander, a first load, a first work recovery compressor, a valve, and a first compressor. The first expander expands a refrigerant. The first load uses the refrigerant 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. The first compressor compresses the refrigerant from the valve.
