Abstract:
A nove l so lar heat pum p w ater heater integrated w ith co llecto r, storage and evaporation is presented, and th is novel sy stem can reduce hea t ex chang ing losses and m anufac tur ing cost. By add ing phase changem a terials into the co l lector / sto rage / evapo ra to r, the so lar energy is stor ied as latent heat o f so lidliqu id phasem ater ia ls. By m ak ing use of the so lar ene rgy as lowtem pe rature source to produce hot w ater, the the rm al effic iency o f hea t pum p system can be signifi cantly increased; mo reover, the operating unstab ility o f the heat pump system caused by interva l so la r energy can be drastically so lved. Though the in itia l investm ent is increased, the system is be tter than the ex isting wa ter heaters in the m arket in term s o fw he ther sav ing energy or sav ing costs. Com pa red w ith the ex isting so lar energy storage heat pump w a ter heate r, the advan tages of low er cost, s imp lified system and h igher reliability wou ld br ing this nove l heat pum p w ater heater to be w ide ly app lied.
