家用淋浴污水源热泵热水器系统实验
Experimental study of domestic shower drain source heat pump water heaters
摘要：
为利用家庭淋浴过程中所排放废水的能量，提出了用于家庭的淋浴污水源热泵热水系统，设计了淋浴废水取热装置,并搭建了系统实验台。实验研究了淋浴过程中不同取热模式下的系统性能，分析了预热水环路对于系统特性的影响。实验结果表明，经过预热水环路后，出口水温提高了8.3 ℃，系统的平均COP由无预热水环路时的2.19提高到3.21。
Abstract：
To utilize the energy of domestic shower drains, puts forward a water heater system using shower waste water source heat pump for family. Designs a shower waste water heat extraction device and sets up a system test platform. By means of experiment, discusses the system performance under different heat extraction modes during shower. Analyses the effect of pre-heated water loop on the system characteristics. The results show that the outlet water temperature is increased by 8.3 ℃ through the pre-heated water loop, and the corresponding average COP of the system is increased to 3.21 from 2.19 without the pre-heated water loop.
