Thermo-hygrometric comfort in the lecture hall of a library: methodology and experimental evidence.

Risultato della ricerca: Articlepeer review


The present study verifies the thermo hygrometric comfort conditions in subjects of a university library users, evaluating the differences and peculiarities in the data collected at the measurement campaign.Particularities of the investigation is the period studied concerning the time frame of the Middle season, which is not expected to power the air conditioning systems. Based on assumptions on the thermal resistance of clothing in the spring and the metabolic type of subjects, the environmental parameters were monitored in some work position in the reading hall in thelibrary of the Faculty of Medicine and Surgery of the University of Palermo. The article presents analyses of the measured data correlating the passive structure behavior and the variation of the internal temperature increases caused by the occupants and by the external temperature gradient. These results are compared with the limits and the guidelines provided by legislation for the main variables measured and derived, and which constitute the essential support to test the tolerability of the occupiers against the thermal environment with which they interact. Keywords: PMV PPD Indexes, Thermo-hygrometric comfort, acceptability classes.
