ÖZET: Bu çalışmada, güneş enerjisi destekli tek etkili Su-Lityum Bromür (H2O-LiBr) karışımı kullanan absorpsiyonlu soğutma makinası kullanılarak Kahramanmaraş kentinde inşa edilmiş bir apartman dairesinin soğutulması sağlanmıştır. Çalışmada, TS 825 standartları ve Kahramanmaraş kentinin yaz hava koşulları göz önüne alınmıştır. Odalarda istenilen sabit iç ortam sıcaklığını korumak için hesaplanan soğutma enerjisi ihtiyacı, absorpsiyonlu soğutma sisteminin kolektörleri vasıtasıyla güneş enerjisinden karşılanmıştır. Hesaplamalarda Engineering Equation Solver (EES) ve Matrix Laboratory (MATLAB) programları kullanılmıştır. Apartman dairesinin soğutma enerjisi talebine göre farklı tip kolektörler (düz plakalı ve vakum tüplü kollektör) göz önüne alınarak gerekli olan kolektör yüzey alanı hesaplanmıştır.Anahtar kelimeler: Absorpsiyonlu Soğutma, Güneş Enerjisi, Güneş kolektörü, Etkinlik katsayısı. Cooling of an Apartment by Using Absorption Refrigeration System in the City of Kahramanmaraş ABSTRACT :In this study, cooling of an apartment constructed in the city of Kahramanmaraş by using solar-assisted single effect absorption refrigeration machine, which uses water-lithium bromide (H2O-LiBr) mixture, has been provided. In the study, TS 825 standard and summer weather conditions of the city of Kahramanmaraş have been considered. In order to maintain the desired rooms's constant indoor temperature, the calculated cooling energy requirement has been met from the solar energy by means of collectors of the solar assisted absorption cooling system. In calculations Engineering Equation Solver (EES) and The Matrix Laboratory (MATLAB) programs were used. According to the apartment's cooling energy demand, required collector surface area has been calculated by considering different types of collectors (flat plate and evacuated tube collectors).

ÖZET: Bu çalışmada, aynı boyutta kesilen kabak ve patlıcan dilimlerinin kuruma davranışları deneysel olarak incelenmiştir. Deneyler üç farklı hız (0.5, 1.0 ve 1.5 m/s) ve üç farklı sıcaklıkta (40, 50, ve Experimental Investigation of Drying Kinetics of Pumpkin and Eggplant SlicesABSTRACT: In this study, behaviour of zucchini and eggplant slices has been investigated as experimantally. Experiments have been made in a convective dryer at three different drying air velocity (U=0.5 m/s, 1.0 m/s and 1.5 m/s) and at three different drying air temperatures (40, 50, and 60 °C).The experimental moisture data were fitted to Lewis, Henderson-Pabis and two-term exponential models which are widely used in the literature. The two-term exponential and Henderson -Pabis models were found to describe the drying characteristics of zucchini and eggplant slices better. The variations of diffusion Deff and mass transfer coefficients hm with the drying air temperature and drying air velocity have been investifated. The mass transfer parameters were increased and drying time was decreased with increasing velocity and temperature.
