【 摘 要 】

This paper aims to develop the footplate for shower drain water heat recovery to capture the waste heat from the used hot shower water. In process, the used hot shower water is collected in a water tank and the cold water is guided into the pipe of the heat exchange device of piping tablet immersed in the water tank for heat exchanging. The heated cold water is further mixed with hot water as hot shower water, so that the required hot shower water rate is reduced and the energy consumption also reduced. The results show that employing one heat exchange device of piping tablet immersed into the ca. 40.6℃ water tank of 60 cm × 60 cm × 15 cm and the cold water with flow rate of 2 l/min got the heat exchange efficiency of ca. 44.34 %. Moreover, using three heat exchange device of piping tablet received the average heat exchange efficiency of ca. 94.21 % and the average heat transfer effectiveness(ε) was ca. 0.94.
