【Abstract】 To explore the feasibility of applying CNTs/paraffin composites to heat pump water heater system, the heat transfer characteristics of energy storage heat pump water heater were analyzed. It was shown that the heating and cooling rates of nanocomposite phase change materials were significantly improved upon the addition of CNTs nanoparticles. The running experimental results of the heat pump water heater suggests the reliability of designment of the thermal energy storage and the feasibility of CNTs/paraffin using in the heat pump water heater.更多还原
