PRODUCTIVITY OF SYSTEMS OF VENTILATION OF CIVIL BUILDINGS: PROBLEMS OF PROVIDING AND SOLUTION

Abstract

In article the main problems of ensuring standard air exchanges in rooms of public buildings are investigated. Modern standard requirements to air exchanges of office rooms are considered. Dynamics of concentration of CO₂ in air of a working zone of office room at natural and mechanical ventilation with the air exchanges corresponding to an admissible and optimum level is investigated. It is offered the corrected values of a specific consumption of external air on one person for typical office rooms that allows to minimize a consumption of external air on condition of not excess of maximum concentration limit of concentration of CO₂ in internal air. Use of the offered approach will allow to reduce power consumption by heating of air and to increase power efficiency of systems, including one of indicators, it characterizing - the specific ventilating power of SFP.
