The working air from the heat exchanger expanded by the first expansion turbine and the cooled pressurized working air from the heat exchanger are combined prior to feeding the combined flows to a second expansion turbine. The system including a mixing apparatus in which the recirculating enclosure air from the loop and the cooled combined working air flows from the second expansion turbine are mixed prior to being provided to the enclosure.
