Optimal Design And Economic Analysis Of The Solar Assisted Heat Pump Water Heater

Energy and environment have become a focus matters of the world. The solarenergy is most important basic energy in the renewable energy and a never-failingclean energy sources; how to more effectively and large-scale utilize it hasincreasingly become a hots-pot scientists tap with efforts, A heat pump has the featurethat it can transfer heat from low temperature to high temperature and improve theavailability of low temperature heat sources. It will have a great future thatintegrating solar thermal utilization into heat pump techniques. This thesis analysesthe technical characteristic of heat pump.Using Excel compution function design andcheck the system. This system can supply enough energy to the user all year in theory.Next, using experiment validate that capillary tube can lower the press of evaporatorbefore compressor. Finally, Economic analysis of the solar assisted heat pump havemore advantage than common energy water heater.
