A method and apparatus for conditioning air in an enclosure wherein the air is passed through a heat exchanger where the air is heated or cooled by a primary gas in the heat exchanger; the primary gas flows through a conditioning power circuit wherein the primary gas is compressed thereby heating the same; the compressed primary gas is then either passed through the heat exchanger to heat the air or is further compressed, cooled and allowed to expand to cool the primary gas which then passes through the heat exchanger to cool the air. |
