摘要：
Aiming at the problem that the evaluation method and index of heat storage performance of enclosure structure cannot effectively evaluate heat storage，a new evaluation method and related index of heat storage performance of enclosure structures are proposed based on the concept of diurnal heat storage capacity and finite difference method. The method can obtain the hourly dynamic heat storage of the enclosure structures，the heat storage of different structural levels and the accumulated heat of the material layer and the enclosure structure in a certain period of time and a certain area. Through a simplified building model，this paper obtains the heat storage of different material layers of building envelope in different directions and different parts. The method in this paper can provide a systematic and comprehensive quantitative evaluation method for the actual heat storage effect of building envelope structure，and also provide a method and basis for the design and layout of solar energy buildings in different directions and parts. © 2024 Science Press.
