Feasibility of Reducing Electricity Consumption of Air Conditioning Equipment by Condenser Direct Evaporative Cooling Technology. Example of Case Study in Dubai

The use of air conditioning technology is accompanied by an increase in electricity consumption, which linked to intensification fossil fuel extraction. This turn calls for developing cooling solutions higher energy efficiency. aim this study examine consumption reduction direct evaporative generating cool hot-dry climate regions. At the initial stage, already-installed equipment with a system was studied creation two regression models representing “on” and “off” sequences. Water operation taken into consideration. In following inlet water temperature dependence pre-cooling purposes studied. A mathematical model developed subsequent calculations suggested that there no need pre-cool before it enters therefore consume additional energy. Practical application evaluated based on case Dubai. results present significant saving potential operations approximately 122 MWh per year. return investment office building Dubai featuring hot desert around 4.2 years. purpose advantage compared without technology. provide expediency conducting further research area, particular regards analyzing various materials adiabatic precooling pads, as well possibility using newly metal pad.
