Feasibility analysis of sewage-source heat pumps applied to hospitals

Taking the use of sewage heat in hospitals as goal, continuously tests the sewage flow rate, water quality and temperature within a year in Shanghai. Analyses the variation law of sewage temperature and the correlation between sewage temperature and water temperature or air dry-bulb temperature. Compares the performance among sewage-source heat pump, traditional water chiller and air-source heat pump unit, and discusses the energy saving potential and feasibility of sewage-source heat pump applied to hospitals.
