The Energy-Saving Study of Packaged Air-Conditioner
Energy Efficiency Ratio
Coefficient of performance
|Abstract:||臺灣在2014年空調機銷售量已達1,353,616台，如何運用節能設計以提昇空調設備之EER (Energy efficiency ratio)值，為節能之重要課題。
利用熱力學第一定律分析比較改良壓縮機前後，結果顯示，壓縮機降溫器可減少25%之壓縮機產生熵，並提昇10%之COP (Coefficient of performance)值，於壓縮機消耗功率上降低80 W。|
The number of air-conditioning equipments sold during 2014 in Taiwan is 1,353,616. How to increase EER(Energy Efficiency Ratio) for air-conditioning equipments have become an important issue for saving energy nowadays. This study aims to improve the performance of a R22 boxed air-conditioner, by leading condensed water produced during operation of the air-conditioner into the cooler of the compressor, it brings away compressor heat , decreases entropy production, which leads to compression work decrement, system efficiency increment, and makes better use of water resources. Comparing the compressor before and after improvement by the first law of Thermodynamics, result shows that using compressor cooler reduces 25% of compressor entropy production, raises the COP by 10%, and decreases 80 watts of compressor power consumption.
