Simulation of coupled heat and moisture transfer in air-conditioned buildings

Tools for Performance Simulation of Heat, Air and Moisture Conditions of Whole Buildings

Abstract Humidity of indoor air is an important factor influencing the air quality and energy consumption of buildings as well as durability of building components. Indoor humidity depends on several factors, such as moisture sources, air change, sorption in materials and possible condensation. Since all these phenomena are strongly dependent on each other, numerical predictions of indoor humid...

A Model for Ground-Coupled Heat and Moisture Transfer from Buildings

Analysis of coupled heat and moisture transfer in masonry structures

Evaluation of effective or macroscopic coefficients of thermal conductivity under coupled heat and moisture transfer is presented. The paper first gives a detailed summary on the solution of a simple steady state heat conduction problem with an emphasis on various types of boundary conditions applied to the representative volume element – a periodic unit cell. Since the results essentially sugg...

Modeling of Coupled Moisture and Heat Transfer During Wood Drying

Development of an accurate mathematical model of sufficient generality to evaluate drying processes in materials having diverse moisture transport properties is proposed. The process of wood drying is interpreted as simultaneous heat and moisture transfer with local thermodynamic equilibrium at each point within the timber. The model is a mathematical one treating wood as a continuous and homog...

Modelling Of Heat Transfer In Buildings

The main idea of this article is taking advantage of heat energy accumulation in building walls in order to design more effective heating system. Essential article goal is to simulate thermal construction responses in dependence on changing boundary conditions. Model geometry has been developed in virtual design studio CATIA and implemented in numerical simulation software COMSOL Multiphysics, ...
