Abstract: Taking the 40.5 m2 farm house in the northern area as research object, the simulation model of air source heat pump
radiant heating system was built by TRNSYS software, and the floor, wall and other regenerators were used to store heat during the
valley period by making use of the characteristics of Xinzhou peak and valley electricity price. Under the premise of ensuring the
room temperature, through TRNSYS simulation heating system, the change characteristics of the system under different operation
schemes in valley period were compared and analyzed. With the goal of the lowest annual operating cost, the optimal heat storage
temperature and time during the valley electricity price period were found, and the optimal heat storage operation strategy was
obtained. Compared with the non-heat storage operation strategy, under this strategy, the annual operation cost can be saved by
14.2%, the heat supply 716 kW·h in the heating season can be increased, and the room comfort require-ments can be met.
