以废热水为热源的浴室热泵热水器
Heat-pump water heater applied in bathroom
摘要：
给出了带有浴室废热水余热回收装置的浴室热泵热水器的组成和流程图，借助lg p-h图和T-s图对其进行了理论分析，并计算了不同工况下的理论与实际制热系数。理论分析表明，带浴室废热水余热回收装置的浴室热泵热水器理论制热系数的最大值是普通电热水器的13.4倍，可节约电能92.8％。

Abstract：
Proposes the basic concept of bathroom heat-pump water heater with heat recovery devices, and presents its constitution and flow diagram. Analyses its characteristics from lg p-h and T-s diagrams, and calculates its theoretical and practical COP values. The analysis shows that, compared with conventional electrical water heater, its maximum theoretical COP is 13.4 times over and it is able to reduce about 92.8％ of electricity consumption.
