YOU AND YOUR HEATING & COOLING NEEDS GENERATED FROM WATER TETCO absorbs heat from water and changes his literally free energy source into usable high temperature heat for domestic heating purposes. Step t—'hater, supplied by a well or other suit_.ble source, flows through tubes located inside a water-to- r^'•igerant heat exchanger. Surrounding water tubes is a second container filled with ettreinety cold refrigerant. This cold ref riger an,t absorbs heat from the water, lowering the water temperature to the needed level. Step 2—The refrigerant, which has now acquired a co•isiderable amount of heat Water -to -Refrigerant Heat Exchanger from the water. enters the compressor where it is pressurized, increasing its temperature to approximately 180'F Step 3—The hot re` igerant circulates through a refrigerant-io-air heat exchanger. Air, circulated by a blower unit is heated as it flows past the refrigerant -to -air heat exchanger and :s then distributed throughout the hcme. As the hot refrigerant flows through the refrigerant -to -air heat exchanger, it cools and condenses to a liquid state. Step 4—The expansion device acts as a refrigerant flow restrictor. As the liquid refrigerant leaves, its temperature and pressure are reduced to approximately 3 'F The cold refrigerant now enters the water -to -refrigerant heat exchanger, and the process repeats itself in a continuous cycle. Return to HeatEschanger Water Pressure Tank OPERATION OF THE TETCW WATER -SOURCE AIR CONDITIONING COIL TETCO' directly air conditions by circulating cold water through a large tinned coil. W4rri. air passing across the fins is ccofed as transfers its heat to the colder water No compressor is used in the TETCO' process (as in ordinary heat pumps). The only efectricity consumed is for the operation cf a blower unit and a pump. The large savings are obvious.
