Mathematical Modelling of Living Room with Different Types of Heating and Pressure Conditions WSEAS transactions on heat and mass transfer

Abstract: The paper deals with temperature and average turbulent airflows distributions in living rooms in a 3D approximation using Ansys/CFX software. The heat balance of a room and its dependence on various geometrical and physical factors are also considered. As physical parameters of thermal comfort conditions, the airflow velocities and indoor temperatures with its gradients are analysed. The distributions are calculated depending on the placement of the heater, the type of heating (convector or floor heating), and the pressure difference between opposite walls. The influence of these factors on the air circulation and temperature field, as well as the related heat flows through building structures is analysed. It is shown that it is possible to reduce the heating power and maintain the conditions of thermal comfort in the room at the same time. In addition, the optimal heater location and the best type of room-heating are discussed from different points of view in case of various ventilation conditions
