Research of Sewage Source Heat Pump Applied in Urban Dwelling Community

Abstract

Sewage discharged form urban dwelling community is warm in winter and cool in summer, which is a sustainable resource and has not utilized fully. Sewage-source heat pump (SSHP) system has advantage of energy efficient, economic, environment friendly and broad foreground, which has significance for the development of building energy efficiency (BEE). The past research of SSHP usually set the heat source and heat sink in sewage farm or main-pipe of urban sewage system, and few take the cesspool of dwelling community as heat source and heat sink directly. The author wanted to develop SSHP system by using sewage on the spot of cesspool in urban dwelling community. He chose a representative urban dwelling community from Chongqing and has tested the temperature and flow volume of sewage for more than one year. Based on testing data, the paper developed SSHP applying schemes for air-conditioning, heating and hot-water supplying, which can be handy-applied in the urban dwelling community. The research of this paper aims to broaden the use of SSHP and promote the development of BEE technology.
