Abstract
An induction type air conditioning unit having a first heat exchanger connected to a source of a relatively cold heat exchange medium and a second heat exchanger connected to a source of a relatively warm heat exchange medium. Dampers are provided to selectively direct the air induced from a space served by the unit through either the first heat exchanger, the second heat exchanger, or through a path bypassing both first and second heat exchangers. The dampers are operatively connected to an inflatable bellows. The inflatable bellows is connected to the source of primary air for the induction unit. The primary air pressure in the inflatable bellows is varied in response to changes in room temperature to vary the path of flow of the air induced into the induction unit to thereby obtain a desired temperature for air discharged into said space.
