MATHEMATICAL SIMULATION OF ROOM CLIMATE PARAMETERS
Abstract
The efficient air distribution is directly connected with the possibility of predicting the reliable air parameters. The reliable description of speed and temperature fields in the housing capacity is provided by the mathematical simulation methods based on Navier-Stokes differential equations. To estimate the room climate provided by ventilation and air conditioning systems, the parameter reflecting heat sensitivity should be used. This parameter is detected using three-dimensional fields of thermophysical values obtained by mathematical simulation. The paper presents results of room climate mathematical simulation for three different schemes of air distribution in a room. The Predicted Mean Vote obtained by mathematical simulation using C language software code allows analyzing three schemes of the air distribution for the room climate.
