How Heat Siphon works diagram

YOU PAY FOR 1 UNIT OF ELECTRICITYElectric BTU AND YOU GET 5 to 7* UNITS OF HEATFree BTU

At 1 a unit of electrical energy Electric BTU (you pay for) runs the compressor which sucks evaporating freon gas from the liquid filled evaporator tube. This causes a strong cooling effect (just like sweat evaporates from you skin & cools you off). The gas picks up four units of heat Free BTU (FREE) from the air flowing over the outside of the evaporator tubes.

At 2 the compressor squeezes this gas, causing its temperature to climb above 200° F (93° C) Result: Five units of heat added to the gas.

At 3 the hot,high pressure gas flows through the inside of the condenser coil. The colder 80° F (26° C) pool water picks up the five units of heat from the freon which cools it down back to a warm liquid.

At 4 the warm liquid is forced through a valve. As it drops in pressure, it rapidly expands and becomes extremely cold liquid .This liquid flows back into the evaporator At 1 where it repeats the cycle.

*Piston Heat Siphon models get 4 units of heat from the air at rated conditions. In the case of SX Series Heat Siphon models with our HIGH EFFICIENCY Scroll Compressor, due to their higher efficiency, five to six units of heat are picked up at the evaporator for every unit of electricity used. THIS REULTS IN SIX TO SEVEN UNITS OF HEAT DELIVERED FOR EVERY UNIT OF ELECTRICITY USED!
