Improving the Efficiency of the Supply-and-Exhaust Ventilation System

Abstract

The article considers a schematic diagram of the supply-and-exhaust ventilation system. To increase its efficiency, a regenerative heat exchanger is proposed, which is a heat utilizer in a cold season and, in a warm season, it is a device for evaporative air cooling. The paper presents the results of theoretical studies of hydrodynamics, heat and mass transfer of the device. In addition, an experiment was performed to analyze these processes and experimental data were obtained. Analytical and empirical formulas are determined for the engineering methodology for calculating the heat exchanger on the basis of the two types of research
