ABSTRACT

Nowadays, promoting the development of new energy sources is an important way to achieve the goal of "double carbon", both in the building sector and in industry, the large amount of sewage and waste water discharged is rich in thermal energy, and the rational use of this thermal energy will bring changes to our living standards. With more and more types of heat pumps and improvements in heat pump technology, the utilisation of the thermal energy from municipal wastewater is gradually increasing. This paper investigates the performance of coupling municipal wastewater with a second lithium bromide absorption heat pump for heating, analyses the indirect use of municipal wastewater sources for heat extraction, and develops a dynamic simulation model for the second lithium bromide absorption heat pump, resulting in a 34% energy saving compared to other heating methods by coupling municipal wastewater sources with this heat pump system.
