Abstract
Taking a campus dormitory building as the research object, TRNSYS was used to simulate the three heating systems of the building with air source heat pump (ASHP), electric boiler (EB) and ASHP coupled with EB, respectively. The parameters of indoor temperature, system energy consumption and energy efficiency ratio COP are used as evaluation indexes to compare and analyze the performance of the three modes. The results show that: the total energy consumption of the ASHP coupled with EB heating system during the heating period is 433,978 kWh. Among which, the electrical energy consumed by the ASHP is 329,567 kWh, and the average COP of the heat pump is 2.64, which is 0.17 higher than the average COP when the ASHP system alone is used for heating. Moreover, the best economy is achieved when the ASHP accounts for 80% of the coupled heating system.
