DEVELOPMENT OF A COMFORT LEVEL MANAGEMENT SYSTEM FOR UNDERGROUND OPEN SPACE PREMISES

Abstract

Underground Open Space facilities, converted from existing underground structures of a different design and functional purpose, have a number of features that significantly distinguish them from similar offices and coworking centers located above ground in buildings. In particular, such facilities have increased relative humidity of indoor air, which is due to planning features and insufficient ventilation, low and uncomfortable temperature indicators of the indoor environment, high and dangerous levels of radon and indicators of microbial contamination of surfaces by bacteria, fungi and viruses. Research of microclimate and comfort indicators in underground structures with high humidity and low indoor air temperature, in which conditions for the constant stay of a large number of people were not provided, analysis of comfort indicators, physiological and psychological consequences of staying in underground spaces, such as psychological depression, boredom and fear, allow developing a system for managing normalized air environment indicators and comfort levels for safe and productive work of people in underground Open Spacetype premises. It is proposed to maintain microclimate indicators based on combined supply and exhaust ventilation systems with recuperative air dehumidifiers, the possibility of temperature zoning of the space with orientation to the largest concentration of people and the possibility of correcting temperature stratification, regulating radon levels, as well as maintaining the aeroionic and microbiological composition of the air in the underground space to increase work productivity and safety of long-term stay in such premises.
