Abstract

The whole system was simulated by TRNSYS software, and the most suitable volume of the hot water collection tank was first simulated, and then the energy consumption of the system and the COP of the sewage source heat pump unit were analyzed according to the simulation data. The results show that the proportion of energy provided by solar energy in one year is 16.6%, and the proportion of sewage source heat pump units is 58.4%. The energy consumption of gas boilers accounted for 69.3%, the energy consumption of sewage source heat pumps accounted for 29.7%, and the energy consumption of solar sewage source heat pump systems was 174,804.7kWh, with an average energy saving rate of 74.8%. Compared with the original gas boiler system, it saves 375,000 yuan in operating costs, 1263 tons of standard coal and 3473 tons of carbon emissions per year. Outstanding performance, far better than the original gas boiler system.
