Air Conditioning and Heating System

Abstract

An air conditioning/heating system that distributes, through a closed loop water circulating system, cold or hot water to one or more separate air handlers that are connected to a central water chiller/heat pump by supply and return lines for each handler. The system includes a cabinet, an insulated tank within the cabinet, a main coil within the tank, the main coil having a recirculation line with a water inlet and a water outlet, and a refrigerant line attached to the recirculation line; a heat pump/condensing unit connected to the refrigerant line, a circulating pump having a pump inlet and a pump outlet, the pump outlet connected to the water inlet of the main coil, a second tank connected to the pump inlet; at least one air handler having a box, a blower within the box, and a secondary coil within the box, the secondary coil having a supply inlet connected to the outlet of the first coil and a return outlet connected to the second tank.

1 . An air conditioning and heating system comprising:
 an insulated tank;   a main coil within the insulated tank, the main coil having a recirculation line with a water inlet and a water outlet, and a refrigerant line attached to the recirculation line;   a heat pump/condensing unit connected to the refrigerant line;   a circulating pump having a pump inlet and a pump outlet, the pump outlet connected to the water inlet of the main coil;   a second tank connected to the pump inlet; and   at least one air handler connected to the main coil and the second tank, the at least one air handler having a box, a blower within the box, and a secondary coil within the box, the secondary coil having a supply inlet connected to the water outlet of the main coil and a return outlet connected to the second tank.   
     
     
         2 . The system of  claim 1  wherein the insulated tank is sealed. 
     
     
         3 . The system of  claim 1  further comprising a volume of water within the insulated tank. 
     
     
         4 . The system of  claim 1  further comprising flexible lines interconnecting the return coil outlet and the second tank and interconnecting the supply inlet and the water outlet of the main coil. 
     
     
         5 . An air conditioning and heating system comprising:
 a main coil and a tank of water;   the main coil having a refrigeration line and a recirculation line, wherein said refrigeration line is directly attached to the recirculation line;   the main coil is immersed in the tank of water.   
     
     
         6 . An air conditioning and heating system comprising:
 at least one air handler, at least one flexible water line, and at least one air conditioning and heating unit;   wherein the a air handler is connected to a air conditioning and heating unit by a flexible water line.   
     
     
         7 . A method of conditioning and heating air comprising the steps of:
 introducing water to a main coil immersed in tank of water wherein said main coil comprises at least one recirculating line directly attached to at least one refrigeration line;   the water travels through the main coil, out of the main coil, and into a flexible supply line;   the water travels though said flexible supply line into an air handler.
