Secondary heating and cooling system

Abstract

A heating and cooling system operates in a supplemental heating mode or a supplemental cooling mode. In supplemental heating mode, the system carries water from a hot water supply of the water heater to a heat exchanger within an air passage in the furnace to heat the building. In the supplemental cooling mode, the system carries cool water from a cool water storage tank to the heat exchanger within the furnace to assist in cooling the building.

1 . An auxiliary cooling system comprising:
 an air conditioning coil;   a secondary cooling coil;   a holding tank;   a outline pipe sending water from the holding tank to the secondary cooling coil;   a return pipe returning water from the secondary cooling coil to the holding tank; and   a pump circulating the water through the tank, the secondary cooling coil, the outline pipe and the return pipe.   
   
   
       2 . The auxiliary cooling system of  claim 1 , wherein the holding tank holds a plurality of rools of soapstone in its interior. 
   
   
       3 . The auxiliary cooling system of  claim 2 , wherein at least one of the outline pipe and the return pipe are connected to a temperature gage. 
   
   
       4 . The auxiliary cooling system of  claim 3 , wherein the outline pipe and the return pipe have a shut off valve. 
   
   
       5 . The auxiliary cooling system of  claim 4 , wherein the return pipe is attached to an air separator. 
   
   
       6 . The auxiliary cooling system of  claim 2 , wherein the pump is controlled by a thermostat of the air conditioner. 
   
   
       7 . The auxiliary cooling system of  claim 2 , wherein the holding tank includes a fresh water inlet and a drain plug. 
   
   
       8 . The auxiliary cooling system of  claim 1  further including a thermostat controlling operation of the pump based upon temperature. 
   
   
       9 . The auxiliary cooling system of  claim 1  wherein the pump is switched on based upon the air conditioning coil being switched on. 
   
   
       10 . The auxiliary cooling system of  claim 1  wherein the water is cooler than ambient air. 
   
   
       11 . A method for cooling an area including the steps of:
 a) circulating cool water through a heat exchanger and a storage tank; and   b) circulating air over the heat exchanger and an air conditioner coil into the area.   
   
   
       12 . The method of  claim 11  wherein said step a) is performed only when an air conditioner including the air conditioner coil is operating. 
   
   
       13 . An auxiliary heating and cooling system comprising:
 an air conditioning coil;   a secondary coil;   a furnace;   a cool water tank;   a hot water tank;   a water supply passage connected to the secondary coil;   a water return passage connected to the secondary coil;   a first valve connecting the cool water tank and the hot water tank to the water supply passage, the first valve selectively switching between the cool water tank and the hot water tank; and   a second valve connecting the cool water tank and the hot water tank to the water return passage, the second valve selectively switching between the cool water tank and the hot water tank.   
   
   
       14 . The system of  claim 13  further including at least one pump for circulating the water through the secondary coil.
