Experimental assessment of various control algorithms for direct evaporative cooling systems
The use of air conditioning systems for comfort and space cooling is a major driving factor for the rising energy demand, accounting for nearly 10% of all the global electricity consumption today. The direct evaporative cooling systems is an energy efficient alternative for conventional vapor compression based cooling systems, particularly in hot and dry climate. The study aims to explore the potential for enhancing the comfort hours offered by the direct evaporative cooling system, through development of advanced control algorithms. The algorithms will modulate various performance variables to increase the comfort hours, The control algorithms thus developed for the cooling system will be tested in a controlled experimental setup, as well as through energy simulations. The experimental data will be used to assess the energy savings achieved by a controlled system as compared to a normally operated evaporative cooling system.
