    • A heat pump water heater system includes a water storage tank and a sealed heat pump cycle with a compressor, a condenser or gas cooler, an evaporator, and a refrigerant. The condenser/gas cooler is disposed in a heat exchange relationship with at least a portion of the water storage tank for heating water within the tank. The tank includes an outlet through which hot water is discharged, and a cold water inlet that is disposed so as to introduce cold water into the tank at a location of a bottommost portion of the condenser/gas cooler. The cold water introduced into the tank is not pre-heated by hot water in the tank so as to establish a thermodynamically efficient temperature differential between the cold water and hot water in the tank.
    • 热泵热水器系统包括储水箱和具有压缩机,冷凝器或气体冷却器,蒸发器和制冷剂的密封热泵循环。 冷凝器/气体冷却器与储水箱的至少一部分以热交换关系设置,用于对罐内的水进行加热。 容器包括排出热水的出口,以及设置成在冷凝器/气体冷却器的最底部位置将冷水引入罐中的冷水入口。 导入罐中的冷水不会通过罐中的热水预热,以便在冷水和罐中的热水之间建立热力学有效的温差。
