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

摘要

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