Ecological hygienical expertise of the efficiency of room air environment optimisation with the recirculative unit “Potok-150M”

Abstract

This work is dedicated to the study of the application possibility of the recirculative unit “Potok 150M” (it works according to the principal of the combined electrostatic and mechanical filter) for optimisation of air environment (AE) in the interior premises. With the unit operating under experimental and natural conditions the quality of AE was estimated according to indexes of concentration of aerosol particles (AP), microbe flora (M F), viruses and fungous flora (FF) in air and biologically active gaseous substances (BAYS). The unit ensured the effective drop of AP, MF, FF, styrolene, butylacetate, heptane, O-xylene, benzole, I-m ethy-3-ethylbenzole, 2-methylheptane and other BAYS in AE. The moderate enrichment of AE with light air ions and ozone was also registered. Time of unit operation unit was determined by concrete conditions of micro climate and architecture of premises. Thus, the recirculative unit “Potok 150M” allows to attach qualities to AE according to claimed demands of modern healthy dwelling and hospital premises.
