Cooling, heating and ventilation system

Claim 1

An air cooling heating and ventilation system for a room or like substantially enclosed space within a building or like structure having a ceiling and a floor, said room having: an upper room portion, a lower room portion and an intermediate room portion between the upper and lower room portions, said upper room portion extending from the ceiling downwardly to the intermediate portion and defined by the presence of air therein which is normally hotter than air in the lower room portion due at least in part to convection, said lower room portion extending from the room floor upwardly to the intermediate portion and defined by the presence of air therein which is normally cooler than air in said upper room portion due at least in part to convection, and said intermediate portion between said upper and said lower room portions being defined by the presence of air therein which is normally cooler than most of the air in the upper room portion. a. ceiling fan means mounted in the room in the upper room portion thereof for forcing air flow between the upper and lower portions of the room, b. air cooling means including condenser means mounted in the lower room portion of the room and disposed and structured for cooling and delivering air into the room, said air cooling means including a first air intake in the lower room portion for air to be cooled and a first air outlet means for cooled air exhaust in the lower room portion; c. outlet venting means formed in said building in the upper room portion for venting of air from the room; d. an inlet venting means formed in said building in spaced relation to and below and in fluid communication through said building with said outlet venting means for flow of air into and out of said room; e. said outlet venting means and said inlet venting means, each including closure means secured thereto and structured for selectively closing and opening of said venting means whereby air flow therethrough is regulated; f. said air cooling means comprising a second air intake means and a second air outlet means, both disposed in fluid communication within the room and disposed in spaced relation to one another and at different heights within the room, said second air intake means being below said upper room portion and above said first air outlet means to draw air down from the upper room portion; said second outlet means being above said second air intake means and above said lower room portion, and said air cooling means including conduit means in fluid flow relation with said air cooling means, said conduit means providing a fluid flow path between said second air intake means and second air outlet means and including means for drawing air from said upper room portion through said conduit means and out said second outlet means in said upper room portion to serve as a heat sink for said condenser means, whereby hot exhaust air from said second air coolihg means is delivered to said upper room portion; and g. said system being operational in at least a cooling mode, and said cooling mode at least partially defined by cool air delivered from said air cooling means through said first air outlet means into said lower room portion.
