ADYABATİK SOĞUTMA SİSTEMLERİNDE NOZUL YAPISININ SOĞUTMA PERFORMANSINA ETKİLERİNİN TEORİK VE DENEYSEL İNCELENMESİ

Year 2016, Volume: 4 Issue: 3, 83 - 90, 30.09.2016

Abstract

Küresel ısınma, yaşam standartlarındaki artış vb. etkenler soğutma ve iklimlendirme sistemlerine olan talebi her geçen gün artırmaktadır. Bu sistemlerin performanslarının artırılmasına yönelik farklı yöntemler kullanılmaktadır. Bu yöntemlerden biri de soğutma sistemlerinde evaporatif kondenser kullanımıdır. Bu çalışmada, soğutma sistemlerinde evaporatif kondenser kullanımının sistem performansına olan etkileri deneysel olarak analiz edilmiştir. Deneysel sistemin kondenser ünitesi adyabatik nemlendirme yöntemi ile soğutulmuştur. Adyabatik nemlendirme işlemi 0.2, 0.3 ve 0.4 mm çaplarında nozullar kullanılarak gerçekleştirilmiştir. Sistem, hava soğutmalı kondenser kullanımı ve farklı nozul çapları için termodinamik olarak analiz edilmiş, sistemin soğutma performansları karşılaştırılmıştır. Elde edilen veriler evaporatif kondenser kullanımıyla, kompresör işinde %8.48 azalma, soğutma sistemi COP değerinde %32.92 ve tüm sistemin COP değerinde ise, %18.43 artış olduğunu göstermiştir.
