Evaporative Air Coolers Optimization For Energy Consumption Reduction And Energy Efficiency Ratio Increment

Abstract

Significant quota of Municipal Electrical Energy<br> consumption is related to Decentralized Air Conditioning which is<br> mostly provided by evaporative coolers. So the aim is to optimize<br> design of air conditioners to increase their efficiencies. To achieve<br> this goal, results of practical standardized tests for 40 evaporative<br> coolers in different types collected and simultaneously results for<br> same coolers based on one of EER (Energy Efficiency Ratio)<br> modeling styles are figured out. By comparing experimental results<br> of different coolers standardized tests with modeling results,<br> preciseness of used model is assessed and after comparing gained<br> preciseness with international standards based on EER for cooling<br> capacity, aeration, and also electrical energy consumption, energy<br> label from A (most effective) to G (less effective) is classified; finally<br> needed methods to optimize energy consumption and coolers’<br> classification are provided.{"references": ["Power Researches Center, Household Electric Statistical Analysis\nReport.
