Abstract

This paper focuses on near-zero energy residential buildings is in hot summer and cold winter regions. The operation model of the solar-air source heat pump for underfloor radiant heating system is established on the TRNSYS simulation platform, and the related evaluation method for energy flexibility potential of the system is constructed. The characteristics of flexible energy use of the system under different adjustment strategies are analyzed through two evaluation indices of “energy consumption reduction during peak hours” and “increase in solar heat collection”. The results show that the system has significant potential of flexible energy use, which can effectively reduce the energy consumption during peak hours and increase the solar energy utilization. Among them, when the adjustment strategy of “the heat pump does not run during the peak period from 08:00 to 22:00” is implemented, the flexible energy use potential of the system is the highest, and the energy consumption reduction of the system during the peak period of the heating season is 125 kW·h, with a reduction ratio of 63%. At the same time, the solar heat collection improves by 98 kW·h, with an increase ratio of 20%.
