Thermal Comfort in University Computer Laboratories
Thermal Comfort in University Computer Laboratories is a scholarly work, published in 2018 in ''Structure and Environment''. The main subjects of the publication include architectural engineering, aeronautics, engineering physics, environmental science, information science, thermal comfort, and engineering. Thermal comfort defines the state of satisfaction of a person or a group of people with thermal conditions of the environment in which the person, or the group of people is staying.The state of satisfaction depends on the balance between the amount of heat produced by the organism in the process of metabolism and heat loss from the organism to the surrounding environment.It has an effect on the quality and efficiency at work, and indirectly also on the presence of symptoms of Sick Building Syndromes (SBS).Due to differences in body structure, metabolism, clothing etc., it is not possible to create a satisfactory thermal environment for all the people staying in it.However, there are parameter values, which maintained at an appropriate level, allow to meet thermal expectations of even 95% of people staying in this environment.The article presents the results of tests conducted in the university computer rooms.The studies included measurements and analysis of typical internal microclimate parameters: temperature, relative humidity and CO 2 concentration.The results raised considerable reservations and therefore in order to assess fully the conditions of use, it has been decided to conduct evaluation of thermal comfort in rooms analysed.In addition, the surrounding surface radiation temperature and clothing insulation of users have been specified.On the basis of the obtained data, PPD and PMV index values were determined in accordance with the standard EN ISO 7730:2005 Ergonomics of the thermal environment -Analytical determination and interpretation of thermal comfort using calculation of the PMV and PPD indices and local thermal comfort criteria 3.
