Performance evaluation of different air-side economizer control methods for energy efficient building

Öz:
Tam havalı iklimlendirme sistemlerinde serbest soğutma uygulaması ile önemli ölçüde enerji tasarrufu sağlanabilir. Ekonomizer çevrim olarak da bilinen bu uygulamada, uygun koşullardaki dış hava soğutucu olarak kullanılır. Serbest soğutma için en önemli parametre yerel iklim özelliğidir. Ancak, meteorolojik verilerin detaylı analizi ile bir bölgenin serbest soğutma potansiyeli belirlenir. Bu çalışmada, tam havalı bir iklimlendirme sistemi ile iklimlendirilen Antalya'daki bir ticari bina için, dış hava sıcaklık ve entalpi kontrollü serbest soğutma uygulamalarının enerji analizi yapılmıştır. Örnek uygulamada, en yüksek enerji tasarrufu oranı, entalpi kontrol stratejisi ile elde edilmiştir.

Energy saving in all-air air-conditioning systems can be significantly improved by using free cooling application. This application, commonly known economizer cycle, is used when outside conditions are suitable, being cool enough to be used as a cooling medium. The most important and characteristic parameter for free cooling is local climatic features. However, detailed analysis of weather data determines the free cooling potential of a region. In this study, energy analysis of the free cooling applications with the outdoor air temperature and enthalpy controls are carried out for a commercial building conditioned by all-air air conditioning system in Antalya. The results obtained from the sample building analysis show that for all working modes the highest energy saving ratio is obtained by enthalpy control strategy.
