SÜRDÜRÜLEBİLİR MOBİL YAŞAM ALANLARI İÇİN ELEKTRİKLİ SU ISITICILARININ KONTROL SİSTEMİ ÜZERİNE KARBONSUZLAŞTIRMA VE ENERJİ MODELLEMESİ

Öz

Enerji verimliliğini artırmak ve güç tüketimini azaltmak amacıyla, bu çalışmada karavanlar ve mobil evler için bir DTE (Çift Tanklı Elektrikli Su Isıtıcısı) modeli tasarlanmıştır. MATLAB/Simulink ortamında, mevcut tek tank modeli ile bu çalışmada geliştirilen DUT (Çift Tanklı Model) çalıştırılmış ve enerji tüketimleri analiz edilmiştir. EWH (Elektrikli Su Isıtıcısı) tank modellerini simüle etmek için tipik bir günlük hanehalkı su kullanım profili oluşturulmuş; bu profil, farklı coğrafi bölgelerden (kıyı, iç kesim, kırsal ve kentsel alanlar) seçilen 25 hanenin Ekim-Mart dönemi boyunca kaydedilen saatlik sıcak su kullanım verilerine dayanmaktadır. Evin sıcak su kullanımını taklit etmek için iki tank kullanılır ve tankların enerji kullanımı karşılaştırılır. Her iki tankın enerji tüketim miktarlarına bağlı olarak sera gazı (GHG) emisyonları da hesaplanır. DUT'un enerji tüketimi tek tanktan daha düşük olduğundan, GHG emisyon miktarı da daha düşüktür. DUT modeli, tek tanklı modele kıyasla ortalama %47,1 daha düşük enerji tüketimi sağlamaktadır. DUT modeli 1000 W güçte çalışırken toplam enerji tüketimi 1200 kWh'den 635 kWh'ye düşmüştür. Sera gazı emisyonlarında da benzer bir azalma gözlemlenmiştir; DUT modeli, tüm güç oranlarında (500 W, 1000 W, 1500 W) tek tank modeline göre %47,1 daha az GHG emisyonu gerçekleştirmiştir. Düşük güç değerlerinde (500 W) DUT modeli, 300 kg CO2 emisyonunu 159 kg CO2 emisyonuna düşürerek %47'lik bir azalma sağlamaktadır.

DECARBONIZATION AND ENERGY MODELING ON THE CONTROL SYSTEM OF ELECTRIC WATER HEATERS FOR SUSTAINABLE MOBILE LIVING SPACES

Öz

In order to ensure energy efficiency by reducing power consumption, a DTE model designed for use in caravans and mobile homes was developed. In Matlab/Simulink, the only tank model that is currently in use and the DUT developed in this study were operated and the energy uses were examined. In order to simulate the EWH Tank models, a typical daily household water use profile is created and water consumption data is based on the hourly hot water usage profile recorded from different geographical regions (such as coastal, inner, rural and urban areas). Two tanks are used to mimic the use of hot water of the house and the energy use of the tanks is compared. Greenhouse gas (GHG) emissions are also calculated depending on the energy consumption amounts of both tanks. Since the energy consumption of DUT is lower than a single tank, the GHG emission amount is lower. The DUT model provides an average of 47,1 % lower energy consumption compared to a single tank model. While the DUT model works with 1000 W, total energy consumption has dropped from 1200 kWh to 635 kWh. A similar decrease in greenhouse gas emissions was observed; The DUT model performed 47,1 % GHG emissions at all power ratios (500 W, 1000 W, 1500 W) than a single tank model. The DUT model at low power values (500 W) reduces the 300 kg CO2 emissions to 159 kg CO2 emissions and provides a decrease of 47 %.
