Abstract

A regenerative fresh-air air conditioning system moves ingoing and outgoing air through a building structure and includes an ingoing air portion wherein the ingoing air is filtered and then pre-cooled by a pre-cooling heat pipe. The ingoing air is then moved by a blower to an evaporator where the air is further cooled and a resulting condensate forms. The cooled air is then supplied to the building by a supply register. Outgoing air passes across a wet heat pipe which is wetted by the condensate from the evaporator and may also be wetted by condensate from the pre-cooling heat pipe. The outgoing air is then sub-cooled and mixed with fresh air by a fan which moves the mixed fresh and outgoing air across a condenser and exhausts the mixed air from the building structure.
