Energy Consumption Simulation and Heating Energy Saving Optimization Study of Flat-roof Single-story Residential Buildings
Abstract：Taking a flat-roof single-story residential building in Lanzhou as the analysis object, this study sets relevant parameters of the building envelope and outdoor temperature, simulates its winter heating heat load using DeST-h software, and designs an optimized scheme for solar-assisted air-source heat pump floor radiant heating system. The results show that the hourly heating load of the building in winter ranges from 846.7 to 4,980.4 W, with a unit area heating load ranging from 11.20 to 65.88 W/m²; the solar collector area should be 25 m², and the domestic hot water load is 222 W. This optimization scheme can significantly reduce building energy consumption and has good energy-saving effects and promotion value.
