Wet-Bulb Analysis on a Maisotsenko Parallel Flow Cooling System with Variations in Water Mass Flow Rate**

Abstract

Air cooling systems in buildings generally use mechanical vapor compression, which is energy-intensive and has a negative
impat on the environment. As an alternative, Maisotsenko cooling system (Maisotsenko Cycle) is capable of cooling air to near
dew point without increasing humidity. This study aims to investigate the effect of variations in water mass flow rate on wet
bulb effectiveness in a parallel-flow Maisotsenko system. The method used is an experiment involving adjusting the number of
nozzles to achieve variations in water mass flow rate under constant airflow conditions. The results show wet buld effectiveness
increses as the difference between the dry buld and wet buld temperatures off cool the outlet air to below the inlet wet buld
temperature.
