Abstract

Isıtma, havalandırma ve iklimlendirme sistemlerinin sanayide ve konutlarda bir çok uygulaması bulunmakta ve dünya etrafındaki ülkelerin enerji tüketiminde büyük bir rol oynamaktadır. Bu sistemlerin dinamik davranışları analiz edilerek daha verimli çalışılmaları sağlanılabilir. Bu çalışmada bir buhar sıkıştırma çevriminin dinamik davranışı analiz edilmiştir. Evaporatör ve kondenser sonlu farklar yöntemiyle, genleşme vanası ve kompresör ise statik denklemlerle modellenmiştir. Evaporasyon ve kondensasyon korelasyonları olarak sırasıyla Gungor-Winterton ve Travis vd. korelasyonları kullanılmıştır. Genleşme vanası açıklığı ve kompresör motor hızı sisteme girdi değişkenleri olarak seçilmiştir. Önerilen sistemin doğrulanması için aynı dizayn özelliklerine sahip başka bir model SimulationX ortamında oluşturulmuştur. İki model de seçilen girdi değişkenlerinin belirli sürelerle değişen farklı değerine simülasyon zamanı boyunca maruz bırakılmış ve sistemlerin dinamik davranışları gözlenmiştir. Elde edilen sonuçlar iki modelin çıktılarının benzer olduğunu göstermiştir. En büyük tahmin farkı ısı değiştirgeci giriş sıcaklıklarında 1.4 K, kütlesel debilerde ise 2x10-4 kg/sn olarak gözlenmiştir.

Development and Validation of a Dynamic Vapor Compression Cycle Model

Abstract

Heating, ventilation and air conditioning systems have widespread household and industrial applications and play a leading role in the energy consumption of countries around the world. By analyzing the dynamic behavior of these systems, it is possible to make them operate more efficiently. In this study, the dynamic behavior of a vapor compression cycle is analyzed. The evaporator and condenser are modeled with the finite-difference method and the expansion valve and compressor are modeled with static relationships. Gungor-Winterton and Travis et al. correlations are, respectively used as the evaporation and condensation correlations. The expansion valve openness and compressor motor speed are selected as the input variables to the system. Another model with the same design specifications is developed in the SimulationX environment to verify the proposed model. Both models are perturbed with the two input variables with varying values over constant intervals and the transient behavior of the system is investigated. The results showed that the outcomes of the two models agree well with each other. The largest prediction difference is observed as 2x10-4 kg/sec. for the mass flow rates and 1.4 K for the heat exchangers inlet temperatures.
