Abstract
İklimlendirme sistemlerinde; konfor, enerji verimliliği, kurulum ve işletme kolaylığı açısından değişken debilisoğutucu akışkan (VRF) sistemleri son zamanlarda yaygın olarak kullanılmaya başlamıştır. Bu sistemlerde,cihazın içinde bulunan soğutucu akışkan sayesinde ısıtma ve soğutma işlemi yapılabilmektedir. İklimlendirmesistemlerinde kullanılan diğer bir uygulama ise Fan Coil (FCU) sistemidir. Fan coil sistemi enerjinin su iletaşındığı ısıtma ve soğutma uygulamasıdır. Konfor şartları ve tasarım taleplerine göre iki (2) borulu ve dört (4)borulu olarak kullanılmaktadır. Bu çalışmada bir cadde mağazasının ısı kayıp kazanç yükleri, TransferFonksiyon Metodu (TFM) yöntemine göre değerlendirme ve analiz yapan Hourly Analysis Program’ı (HAP)kullanılarak hesaplanmıştır. 1076 m2 alan için hesaplanan toplam soğutma yükü 152,93 kW ve ısıtma yükü ise74,9 kWh olmuştur. Hesaplanan mahal ısı yüklerine göre VRF ve FCU sistem ekipmanları seçilmiştir.Seçilen ekipmanlara göre yapılan analizler sonucunda; VRF sistemlerinin yatırım maliyetlerinde %24,6 , işletmegiderlerinde %32,5 ve enerji tüketiminde %33,7 daha fazla avantaj sağladığı tespit edilmiştir. Bu kapasitede kiyapılarda yatırım maliyetleri, işletme giderleri ve enerji tüketimi açısından VRF sistemlerinin kullanılmasınındaha uygun olacağı ortaya konmuştur.
In air conditioning systems; In terms of comfort, energy efficiency, ease of installation and operation, variable_x000D_ flow refrigerant (VRF) systems have recently become widely used. In these systems, heating and cooling process_x000D_ can be performed by means of the refrigerant in the device. Another application used in air conditioning systems_x000D_ is the Fan Coil (FCU) system. Fan coil system is the heating and cooling application where energy is carried by_x000D_ water. It is used as two (2) pipe and four (4) pipe according to comfort conditions and design demands. In this_x000D_ study, the heat loss gain loads of a street store were calculated using the Hourly Analysis Program (HAP), which_x000D_ evaluates and analyzes according to the Transfer Function Method (TFM) method. The total cooling load_x000D_ calculated for an area of 1076 m2 was 152,93 kW and the heating load was 74,9 kWh. VRF and FCU system_x000D_ equipments were selected according to the calculated heat loads._x000D_ As a result of the analysis made according to the selected equipment; It has been found that VRF systems_x000D_ provide %24,6 advantage in investment costs, %32,5 in operating expenses and %33,7 in energy consumption. It_x000D_ has been shown that it is more appropriate to use VRF systems in terms of investment costs, operating costs and_x000D_ energy consumption in buildings of this capacity.
