Z OPERATION OF THE TETCO HEAT EXTRACTOR The TETCU Heat Extractor absorbs low-grade energy r form of heat fn,ni o,,ii —ii. mo :nanye> tr • tc yv-•�ia,i. energy into usable high temperature heat for domestic heating purposes Step 1— Water, supplied by a well or other suitable source. flows through tubes located inside a water to refrigerant neet exchanger. Surrounding the water tubes is a second container. filled with extremely cold refrigerant This cold refrigerant absorbs heat from the er, lowering the water temperature to within several degrees of the freezing point Step 2—The refrigerant, which has now acquired a considerable amount of heat from the water. enters the compresso, where is it pressurized to approximately 245 pounds per square inch. increasing its temperature to approximately 1W degrees Fahrenheit. Step 3—TF.e hot refrigerant circulates through a refrigerant to air heat exchanger Air, circulated by a blower unit. it. heated as it flows past the refrigerant to air heat exchanger and is then distributed throughout the home As the hot refrigerant flows through the refrigerant to air heat exchanger. it coois and condenses to a liquid state Step 4—The expansion device (capillary tube) acts as a refrigerant flow restrictor As the li auid refrigerant leaves the capillary tube, its temperature and pressure are reduced to approximately 32 degrees Fah; enheit and 57 pounds per square inch The cold refrigerant now enters the water to refrigerant heat exchanger and the process repeats itself in a continuous cycle s R.
