【摘要】 相变式储能热泵热水器是一种新型节能热水供应设备。它利用空气作为低温热源,由蒸发器内制冷剂的蒸发来吸收空气中的热量,通过传热盘管将热量传递给相变储能材料,获取盘管承压,使贮罐形状不受压力容器限制贮能。相变材料储能,减少系统体积。通过对相变传热过程分析和燃气热水器、电加热热水器的技术性能和经济性能的比较,指出相变式储能热泵热水器是一种使用前景良好的小型家庭化的高效热泵。更多还原

【Abstract】 Phase change Heat pump water heater is a new style equipment for hot water supply.System uses atmosphere as low temperature heat source.It imbibes heat from atmosphere by evaporation of the refrigerating medium in vaporizer and transfers the heat to phase change materials by heat transfer unit then transfers the heat to cool water from cool water pipe.In this way the form of holder is independent with the pressure container.We make comparison on the technological and the economical quality between the gas-fired heater and electricity heater with heat pump water heater.At last it points that phase change Heat pump water heater is a highly active home heat pump water heater.更多还原
