Standardization of Ultraviolet Irradiation of Rooms and Territories by Energy Criterions
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 23, Issue
Abstract
Compaction of building attended by appearance of negative factors in quality of habitat environment especially of light-insolation condition. In modern Ukrainian standards, criterion of ultraviolet radiation estimation is insolation duration. However, this normalization is imperfect because the solar radiation vary by intensity, spectral distribution, and volume of premises. In addition, insolation does not take into account diffuse and reflected irradiation from surrounding surfaces. Particularly it is important for ultraviolet spectrum region – its density is 70...80% of direct irradiation. For complete accounting of solar irradiation for life sustenance, replacement of time criterions by energy estimation of ultraviolet irradiation is required. That is why aim of this paper is development of methodological principles of this estimation. The paper represents dependences for definition of direct, diffuse and reflected ultraviolet solar irradiation doses. Special attention spare to estimation of diffuse and reflected components because these types of emission irradiate largest part of internal space of premises. It is proposed to determine those types of radiation by new mathematical apparatus of point calculation. An estimation method of the irradiation is offered. Algorithms of standardization of ultraviolet irradiation by energy parameters is proposed
