Abstract: It is well known that the prediction of comfort in buildings is performed either by direct measurement of each microclimate parametre, or by some comfort indices which synthesize the combined influence of more environmental factors implied. This paper approaches the numerical prediction of thermal comfort in closed spaces on the basis of PMV – PPD model, and its testing to asymmetric or nonuniform thermal radiation, as well as the indoor air quality control. It is developed a computation and testing model of thermal comfort in buildings, as well as a methodology to determine the outside airflow rate and to verify the indoor air quality in rooms, according to the European Standard CEN 1752. Also, it is presented the thermal comfort criteria for design of heating systems. On the bases of these mathematical models there were elaborated the COMFORT 1.0 and COMFORT 2.0 computer programs, implemented on compatible microsystems IBM-PC. The COMFORT 1.0 computer program all!
ows both for the direct computation of the PMV (predicted mean vote) and PPD (predicted percent dissatisfied) indices in different points of a room, and their comparative analysis, and the determination of the mean radiant temperature in isolated points or in a series of points situated on a straight line. The COMFORT 2.0 program computes the outside airflow rate for a room ventilation, the number of air exchanges per hour, and the variation in time of contaminants concentration of room air according to European and national norms and analyses influence of different parametres on these sizes. The performance of the developed computational models and the advantages of the proposed computer programs is illustrated by using some numerical comparative applications for two constructive types building.
