Energy efficient solutions for HVAC system 27
Cooling Tower is a device for evaporative cooling of water by direct contact with air Ambient wet bulb temperature is the limiting temperature to which water can be cooled 28
Approach Difference between Cold water temperature and Wet Bulb temperature Range Difference between Hot water temperature and Cold water temperature 29
AC System - highest power consumer of a building Chillers highest power consumer of AC System Chillers must be energy efficient if building has to be energy efficient 30
