在已有建筑热模拟详细模型的基础上，建立了一个完整的建筑湿热模型。热模型是一种经过充分验证的瞬态工具，可以逐小时模拟多区域建筑的热状况。考虑到建筑构件和家具的水分缓冲能力以及室内活动的湿度供应，该模型已扩展为室内湿度条件的瞬态模拟新功能。模型中还集成了所有外部建筑围护结构构件各层湿度条件的瞬态计算。新模型的优点是在同一计算中同时考虑了围护结构的边界条件和建筑材料缓冲室内湿度的能力。该模型考虑了与水分吸收或蒸发相关的潜热效应，并考虑了建筑材料中水分影响其导热性的方式。 本文介绍了该模型的原理、一些应用和计算结果。该模型通过一个全尺寸测试单元的实验数据进行了验证。在试验室中，可以控制室内湿度的释放或释放，并测量室内空气湿度和建筑材料含水量的响应。使用不同的室内材料进行了一系列实验，以提供吸湿和吸湿效果的原始数据。文中给出了模拟数据与实测数据的比较实例。单位:SICitation:Symposium，ASHRAE交易，第109卷，pt。1.

A whole building hygrothermal model has been developed on the basis of an existing detailed model for thermal simulation of buildings. The thermal model is a well-proven transient tool for hour-by-hour simulation of the thermal conditions in multizone buildings. The model has been expanded with new capabilities for transient simulation of indoor humidity conditions, taking into account the moisture buffer capacity of building components and furnishings and the supply of humidity from indoor activities. Also integrated in the model are transient calculations of the moisture conditions in the layers of all the external building envelope components.The advantage of the new model is that both the boundary conditions for the envelope and the capacity of building materials to buffer the indoor humidity are considered in the same calculation. The model considers the latent heat effect associated with the absorption or evaporation of moisture, and it takes into account the way in which moisture in the building materials affects their thermal conductivity.The paper presents the principles for the model and some applications and calculation results.The model is validated against experimental data from a full-scale test cell. In the test cell, it is possible to control the release or withdrawal of humidity from the indoor space and measure the response in humidity of the air and the moisture content of building materials in the room. A sequence of experiments has been conducted using different interior materials to provide source data for the effect of moisture absorption and release. Examples of comparisons between simulated and measured data are presented.Units: SI
