Cooling System

Abstract

A cooling system including a ventilator that exchanges atmosphere between parts of a building that are at differing heights. The ventilator includes an outer conduit that extends from an upper end thereof downward to a lower end thereof. An inner conduit extends substantially the entire length of the outer conduit. Both the outer and inner conduits are open at their respective upper ends and lower ends. Temperatures of atmosphere both surrounding and within the outer conduit and the inner conduit induce an exchange of atmosphere between the ventilator and surrounding atmosphere.

 ii. a floor; and 
 iii. a wall, and 
 the outer conduit having a length that extends from an upper end thereof downward to a lower end thereof; 
   b. an inner conduit extending substantially along the entire length of the outer conduit; and   c. one or more cooling tubes extending along the inner conduit,   wherein the one or more cooling tubes are connected to a pan and have a fluid therein.   
     
     
         2 . The cooling system of  claim 1 , wherein the inner conduit extends beyond the outer conduit and is offset from the portion of the building such that it terminates in a room.

         5 . The cooling system of  claim 1 , wherein at least part of the ventilator is configured to support additional equipment. 
     
     
         6 . The cooling system of  claim 5 , wherein the additional equipment is selected from the group consisting of lighting, fans, displays and combinations thereof. 
     
     
         7 . The cooling system of  claim 1 , wherein the inner conduit has at least one hole formed therethrough for allowing an exchange of air. 
     
     
         8 . The cooling system of  claim 1 , wherein the upper end of the outer conduit is locatable above the roof of the building, and the ventilator further comprises a cover disposed above the upper end of the outer conduit that occludes upper ends both of the outer conduit and of the inner conduit, thereby preventing precipitation from entering thereinto while simultaneously permitting atmosphere to enter thereinto. 
     
     
         9 . The cooling system of  claim 8 , wherein the cover includes mesh that spans between peripheries of the pan and a lid for:
 i. barring entry of insects into the cover, while   ii. permitting atmosphere to circulate therethrough,   whereby volatile liquid in the pan evaporatively cools atmosphere entering the coaxial ventilator.   
     
     
         10 . The cooling system  claim 1 , wherein the outer conduit is configured to use a cavity to assist in moving air flow. 
     
     
         11 . The cooling system of  claim 10 , wherein the cavity is in the form of a roof cavity in the building. 
     
     
         12 . The cooling system of  claim 1 , wherein at least one of the one or more cooling tubes is semi-permeable, thereby providing a surface area thereon for evaporation cooling. 
     
     
         13 . The cooling system of  claim 1 , wherein the pan is semi-permeable, thereby providing a surface area thereon for evaporation cooling. 
     
     
         14 . The cooling system of  claim 1 , wherein (i) at least one of the one or more cooling tubes is semi-permeable, and (ii) the pan is semi-permeable, thereby providing a surface area thereon for evaporation cooling. 
     
     
         15 . A cooling system for inclusion in a building, the cooling system comprising:
 one or more cooling tubes that are configured to be supported by a roof and extend therethrough into a building space;   a pan supported by the one or more cooling tubes, the pan being configured to receive a fluid therein that assists in providing fluid to the one or more cooling tubes,   wherein thermosiphon cooling of the fluid in the one or more cooling tubes assists in cooling the building space.   
     
     
         16 . The cooling system of  claim 15 , wherein the one or more cooling conduits are configured in a manner that they are sufficiently cooled to assist in moving air down the inner conduit. 
     
     
         17 . The cooling system of  claim 15 , wherein at least one of the one or more cooling tubes is semi-permeable for providing a surface area thereon for evaporation cooling. 
     
     
         18 . The cooling system of  claim 15 , wherein the pan is semi-permeable for providing a surface area thereon for evaporation cooling. 
     
     
         19 . The cooling system of  claim 15 , wherein (i) at least one of the one or more cooling tubes is semi-permeable, and (ii) the pan is semi-permeable, thereby providing a surface area thereon for evaporation cooling. 
     
     
         20 . The cooling system of  claim 15 , wherein:
 a. the one or more cooling tubes and a lower portion of the pan is filled with a liquid that is:
 i immiscible in water; and 
 ii. heavier than water; and 
   b. water fills a portion of the pan above the liquid.   
     
     
         21 . The cooling system of  claim 15 , further comprising at least one of a vertical axis exhaust wind turbine and an exhaust fan, wherein the vertical axis exhaust wind turbine or exhaust fan is used to accelerate the air flow over the pan to increase its cooling efficiency. 
     
     
         22 . The cooling system of  claim 15 , further comprising an evaporative cooling mat suspended above and partially submerged in the pan.
