摘　　要：目前我国采用内置保温系统建造的被动式超低能耗建筑案例较少,且没有系统性分析其应用特点,通过实验方式验证了传热仿真具有较高的精度,并在此仿真模型基础上对河北省发布实施的4种内置保温系统进行传热仿真,分析其传热特性并确定了4种内置保温系统的系统修正系数,同时对图集2保温系统构造应用于被动式超低能耗建筑中各热桥节点部分进行仿真计算,确定典型住宅建筑附加传热量及附加传热系数。在上述计算和分析基础上,采用DeST软件分析图集2构造应用于河北省三大气候区建筑能耗情况,并确定了内置保温系统应用于被动式超低能耗建筑的外墙传热系数和挑板末端隔热措施,为后续内置保温系统应用于被动式超低能耗建筑的工程设计提供参考。At present,there are a few passive ultra-low energy consumption buildings built with builtin thermal insulation systems in my country,and there is no systematic analysis of their application characteristics.This paper verifies that heat transfer simulation has high accuracy through experiments,and based on this simulation model the four built-in thermal insulation systems released and implemented by the province conduct heat transfer simulation,analyze their heat transfer characteristics and determine the system correction coefficients of the four built-in thermal insulation systems.The bridge node part is simulated and calculated to determine the additional heat transfer and additional heat transfer coefficient of typical residential buildings.On the basis of the above calculation and analysis,DeST software was used to analyze the structure of Atlas 2 applied to the energy consumption of buildings in the three major climatic regions of Hebei Province,and the heat transfer coefficient and pick plate of the external wall applied to the passive ultra-low energy consumption building by the built-in thermal insulation system were determined.The end thermal insulation measures provide a reference for the subsequent engineering design of the built-in thermal insulation system applied to passive ultra-low energy consumption buildings.
