  • the change in the temperature of air exhausted from the first exhaust means could be affected by changing the flow of air across the respective sides of the heat transfer means, rather than changing the heat transfer means itself.
  • the selection means could be any other suitable selection means capable of changing the direction of the electric current through the thermo electric cooler 18, or changing the direction at which refrigerant flows through the heat pump 118.
