A REVIEW OF THERMAL COMFORT AND METHOD OF USING FANGER'S PMV EQUATION

摘要

Thermal comfort can be described as satisfaction of the mind in an environment. In this satisfied environment, physical and mental productivity of human become higher. For many years, humankind endeavor to develop more comfortable environments. On that way; thermal comfort equation was established by P. O. Fanger in 1970s. "Fanger's comfort equation" is the combined quantitative combination of the environmental and individual variables. Predicted Mean Vote (PMV), as the result of "Fanger's comfort equation", indicates how the occupants judge the climate. Using PMV, the Percentage of People Dissatisfied (PPD) can be predicted. The general purpose of HVAC systems is to provide more comfortable indoor areas and acceptable indoor air qualities. PMV results show that the environment is comfortable or not. This PMV model has become the internationally accepted model for describing the predicted mean thermal comfort of occupants in indoor environments. In this study, the literature about thermal comfort is focused and the method of the PMV application is given step by step. Thermal comfort limits in the recent standards, factors of the thermal comfort, Fanger's PMV and PPD equation were presented in the study. The expression of the study is tried to be extended by tables and figures.
