Experimental Study on a Shower Waste Water Heat Recovery Device in Buildings
Large amounts of heat were waste during showering process, especially in public buildings. In this paper, a waste water heat recovery system containing a clever concept device was designed and set up to investigate the potential for shower water heat recovery. The device can be installed directly on the floor of the shower room and can be used to preheat the cold water going to the water heater. The principle of the device was introduced, and the energy saving effects of the device was studied experimentally with different conditions. The results indicated that more than 50% of the shower waste water heat can be recycled by the high-performance heat recovery device, which indicated that this device has good economic property and could lead to obvious social and economic benefits.
