Mobil Yaşam Alanlarında Karbon Ayak İzinin Azaltılması: Enerji Verimliliği ve Çift Tanklı Su Isıtıcı Modelleri

Öz

Bu çalışma, karavan ve mobil konutlar için tek tanklı (STE) ve çift tanklı (DUT) elektrikli su ısıtıcılarını karşılaştırmaktadır. Beş yıllık veri ve LSTM tabanlı yaz tüketim tahminiyle, sıcak su kullanımının mevsimler arası farkının azaldığı ve yıllık %0.56 düşüş gösterdiği belirlenmiştir. Simülasyonlar, 200 L/1 kW DUT sisteminin STE’ye göre litre başına enerji tüketimini %12.2 azalttığını, Türkiye şebeke emisyon faktörüyle hesaplanan GHG emisyonunu ise ortalama %47.1 düşürdüğünü ortaya koymuştur. Yüksek başlangıç maliyetine rağmen DUT sistemlerinin geri ödeme süresi ortalama 3.5 yıl (yüksek elektrik fiyatlarında 2.65 yıl) olarak hesaplanmıştır. Sonuçlar, DUT mimarisinin mobil yaşam alanlarında sürdürülebilir, düşük karbonlu ve ekonomik bir çözüm olduğunu kanıtlamaktadır.

Reducing Carbon Footprint In Mobile Living Spaces: Energy Efficiency and Double Tank Water Heater Models

Öz

This study compares single-tank (STE) and dual-tank (DUT) electric water heaters for caravans and mobile homes. Based on five years of data and an LSTM-based summer consumption forecast, it was determined that seasonal differences in hot water usage are decreasing, with an annual decline of approximately 0.56%. Simulations revealed that the 200 L/1 kW DUT system reduces energy consumption per litre by up to 12.2% compared to STE, and achieves an average 47.1% reduction in GHG emissions (calculated using Turkey’s grid emission factor). Despite the higher initial cost, the payback period for DUT systems is calculated at an average of 3.5 years (as low as 2.65 years in regions with high electricity prices). The results demonstrate that the DUT architecture provides a sustainable, low-carbon, and economically viable hot water solution for mobile living spaces.
