Nem Alma Malzeme Kaplamalı Isı Değiştiriciler ve Sistem Performansı Değerlendirmeleri

Nem alma, evsel ve ticari binalarda iklimlendirme kontrolü için büyük önem taşı maktadır. Farklı nem alma yöntemleri bulunmaktadır. Soğurucu kullanarak nem alma bu yöntemler arasındadır. Son dönemlerde katı adsorban (soğurucu) kulla nılan sistemlerde döner çark sisteminin yerine katı adsorban kaplamalı ısı değişti ricilerin kullanılması önerilmektedir. Bu sistemler, bir atık ısı kaynağı veya güneş enerjisi kullanılarak gerçekleştirilebilecek adsorpsiyon işlemi ile enerji verimli bir şekilde nem alma sağlayan geleneksel iklimlendirme işlemlerine kıyasla daha iyi bir araçtır. Nem alma malzeme kaplamalı ısı değiştirici, bu tip sistemler için anah tar bir bileşendir. Bu çalışmada, nem alma malzeme kaplamalı ısı değiştiriciler ve sistem performansına olan etkileri günümüze kadar yapılan deneysel ve simulasyon çalışmaları ve bu çalışmalarda elde edilen bulgulara yer verilerek araştırılmıştır.

Desiccant Coated Heat Exchangers and Evaluations of System Performance

Dehumidification is of great importance for climate control in residential and com mercial buildings. Different methods of dehumidification are available. Moisture re moval using the absorbents or adsorbents is among these methods. In recent years, solid adsorbent coated heat exchangers have been proposed to be used instead of rotary sorbent systems in solid adsorbent systems. These systems are a better tools compared to traditional air conditioning processes, which enable energy-efficient dehumidification by adsorption that can be accomplished using a waste heat source or solar energy. The adsorbent-coated heat exchanger is a key component for such systems. In this study, adsorbent material coated heat exchangers and its effects to the system performance were investigated, including experimental and simulated studies completed to daytime and the findings obtained in these studies.
