Measurement of Indoor Environment Parameters in a Classroom Equipped with Heat Recovery Unit

摘要

The article deals with measurement of indoor environment parameters in a classroom equipped with heat recovery unit. The first part of the article is devoted to the own measuring system which is based on NI hardware (LabVIEW) in combinations with measuring sensors. Next part shows results of real time operation with emphasis on the observed CO_2 concentration. Finally, two situations were compared: installation with heat recovery unit (classroom EL319) and installation without heat recovery unit (classroom EL419).
