ABSTRACT:
An air conditioning apparatus (10/30) that has an enthalpy or sensible heat exchanger (22/34) through which fresh air and room air passes for the transfer of heat between a first (18/35) and second path (20/36) of the heat exchanger (34). The first path (18/35) delivers air to a first coil (25/38) to be heated or cooled thereby, while the second path (20/36) is delivered to a further coil (33/39) to be heated or cooled thereby. Air passing through the first coil (25/38) is delivered to the exterior while air passing through the second coil (23/39) is delivered to the interior of the room.
