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.
Claims12
A system, comprising;
- an ingoing air path for receiving ambient ingoing air and channeling said ingoing air into a structure;
- first means mounted in said ingoing air path for moving air through said ingoing air path to provide said ingoing air to said structure;
- second means including a first heat exchange coil containing a heat exchange fluid for cooling the ingoing air to a temperature at which a condensate is formed;
- an outgoing air path for channeling outgoing air from said structure to atmosphere;
- third means mounted in said outgoing air path for moving air through said outgoing air path to exhaust said outgoing air from said structure;
- fourth means including a second heat exchange coil containing a heat exchange fluid for transferring heat to said outgoing air wherein the fourth means is a heat pipe, one end of which is positioned in the ingoing air path and the other end of which is positioned in the outgoing air path;
- and
- fifth means for channeling said condensate to said second coil to evaporatively cool said second coil.
An air conditioning process, for a building structure, comprising the steps of:
- (a) moving ambient air into a building structure through an ingoing air path;
- (b) precooling the ambient air by means of a precooling heat pipe;
- (c) moving the precooled air to an evaporator, where the air is further cooled and forms a condensate;
- (d) circulating the cooled air within the building;
- (e) blowing the cool and outgoing air from the building across a wet heat pipe wetted by condensate from the evaporator;
- and
- (f) mixing the outgoing air with fresh air as the outgoing air moves across a condenser.
