Heat exchange system

Abstract

A system and a method for heating two buildings using geothermal energy comprises pumping a heat transfer liquid through conduits located in a water filled well and then passing the heat transfer liquid through floor conduits located in a first building, subsequently pumping the heat transfer liquid through a reservoir and then back to the well, pumping a second heat transfer liquid through a compressor and using the warm side of the compressor to heat a second building, the second heat transfer liquid being passed through a serpentine arrangement in the reservoir. The first building is normally an outbuilding and the second building is a residence.

1 . A system for heating a first building having a floor and a second building, the system comprising:
 a well having water therein;   a down conduit and an up conduit located in said well;   a portion of at least one of said conduits having a heat exchange section;   a liquid containing reservoir located in said first building;   a plurality of floor conduits in said floor, said floor conduits being connected to said down and up conduit to form a closed loop;   a heat transfer liquid filling said conduits;   a pump for pumping said heat transfer liquid through said conduits;   a compressor, said compressor having a closed loop system containing a second heat transfer fluid, said closed loop system extending into said reservoir; and   a fan arranged to blow warm air from said compressor into said second building.   
   
   
       2 . The system of  claim 1  wherein said heat exchange section comprises a plurality of metallic plates extending outwardly from at least one of said up and down conduits. 
   
   
       3 . The system of  claim 2  wherein said heat transfer liquid comprises a mixture of water and glycol. 
   
   
       4 . The system of  claim 2  wherein said heat transfer liquid comprises a mixture of methanol and water. 
   
   
       5 . The system of  claim 2  wherein said well is located under said first building. 
   
   
       6 . The system of  claim 2  wherein said closed loop system of said compressor includes a serpentine section within said reservoir. 
   
   
       7 . The system of  claim 2  wherein said second building comprises a residence. 
   
   
       8 . The system of  claim 2  wherein said well has a depth in excess of 60 metres. 
   
   
       9 . A method for heating a first building and a second building comprising these steps of;
 pumping a heat transfer liquid through conduits located in a water filled well;   passing said heat transfer liquid from said well through floor conduits located in said first building;   subsequently passing said heat transfer liquid from said floor conduits to a reservoir and subsequently to said conduits located in said water-filled well;   pumping a second heat transfer fluid through a compressor;   passing said second heat transfer liquid from said compressor through conduits located in said reservoir; and   blowing air from a warm side of said compressor to said second building.   
   
   
       10 . The method of  claim 9  further including the step of passing said second heat transfer liquid through a serpentine arrangement of conduits within said reservoir.
