Let alone about the synergistic effect of them all. So, the purpose of this study is to analyze how environmental conditions (higrothermal as well as those related to the presence of detected and undetected pollutants) affects the degree of users acceptance in a room, quantified by the predicted percentage of dissatisfied (PPD). To this effect, it is studied how to minimize the relation between the air flow rate and the PPD, in order to establish the minimum PPD of a room depending on the type and rate of production of pollutants. As a consequence, the age of air that minimizes the PPD under such conditions is obtained. The most fruitful result that can be highlighted is that each room has a typical PPD, which is directly proportional to the ventilation flow rate in the case of velocity and temperature being the causes for discomfort, but inversely proportional when pollutants are considered. The global effect of both causes of discomfort leads to the minimum PPD that can be achieved in the room under certain hygrometric and contaminants conditions. Discussions about the proposed method are finally completed with an application to a clean room, in which research is conducted through the determination of pollutants concentrations, air velocities and air temperatures in the room using the program ANSYS. 收起
