Air source heat pump



Compared with gas, electric and solar water heaters, air source heat pump can provide all-weather hot water with low energy cost. Together with Shanghai Jiao Tong University and other research institutions, Linuo Paradigma has developed a series of heat pump products for both residential and commercial applications and manufactured by the new established production line in Qingpu industrial park, Shanghai, China. All those products adopt world-leading Copeland compressor and high-efficiency heat exchanger, and are manufactured by ISO9001 facilities with strict performance test before ex-factory. The 4.0 COP (Coefficient of performance) of our heat pump system means the operation cost is only 1/4, 1/3 and 2/3 of the electric, gas and solar water heaters’. Besides economical efficiency, heat pump system also has advantages on safety issues since avoiding of electric leakage, heat without water, gas explosion and carbon monoxide poisoning. The air source could be used in 24 hours/day and all weather conditions, which creates air source heat pump the new generation of green energy water heaters.


Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature and pressure are increased, and transfers its higher temperature heat to the condenser and inlet cold water become outlet hot water through heat exchange. Then the fluid temperature and pressure are decreased by passing through throttling device. Then after going through the evaporator, the low temperature and pressure fluid turns from liquid to gas and enters into the compressor again. This cyclic phase change process can continuously heat the water in storage tank. The COP (Coefficient of performance) of this heating process is over 4.0.
