Güneş enerjisiyle çalışan gömülü boru zarf sisteminin farklı zarflarda uygulanabilirliğine ilişkin karşılaştırmalı bir çalışma

Öz

Bu çalışma, TRNSYS ile geliştirilen yeni bir simülasyon modeli kullanarak çeşitli bina zarflarındaki Güneş Enerjisiyle Çalışan Gömülü Boru Zarfı Sisteminin (SEPES) ısıtma verimliliğini karşılaştırmaktadır. Değerlendirme, iç hava sıcaklığını, duvarlardaki giriş ve çıkış suyu sıcaklıklarını, zarfların iç yüzey sıcaklıklarını ve altı farklı SEPES kurulumunda ısıtma enerjisi tüketimini içermektedir. Temel bulgular şunlardır: 1) SEPES, Harbin'deki soğuk kışlarda iç mekan sıcaklıklarını önemli ölçüde iyileştirir, tavan kurulumları sıcaklıkları 8,4℃'ye kadar artırır ve stratejik yerleşimler sıcaklığı ve enerji verimliliğini optimize eder; 2) SEPES borularındaki su sıcaklığı ısıtma kapasitesini gösterir, en yüksek sıcaklıklar doğu ve batı duvar kurulumlarındadır; 3) Tavana gömülü borular ısı kaybını engellemede en iyi performansı gösterir, yüzey sıcaklıkları 7,42℃ ile 11,59℃ arasındadır; 4) SEPES kurulumları günlük ısı yüklerini önemli ölçüde azaltır, tavan kurulumları %49,7'lik en yüksek enerji tasarrufu oranına ulaşır. Genel olarak tavan montajları en etkili olanlardır, bunu kuzey duvarı, zemin, güney duvarı, doğu duvarı ve batı duvarı takip eder.

A comparative study on the applicability of the solar energy-powered embedded pipe envelope system in different envelopes

Öz

This study compares the heating efficiency of the Solar Energy-powered Embedded Pipe Envelope System (SEPES) in various building envelopes using a novel simulation model developed with TRNSYS. The evaluation includes indoor air temperature, inlet and outlet water temperatures in walls, internal surface temperatures of envelopes, and heating energy consumption across six different SEPES installations. Key findings include: 1) SEPES significantly improves indoor temperatures during cold winters in Harbin, with ceiling installations increasing temperatures by up to 8.4℃, and strategic placements optimizing warmth and energy efficiency; 2) Water temperature in SEPES pipes indicates heating capacity, with the highest temperatures in east and west wall installations; 3) Ceiling-embedded pipes perform best in blocking heat loss, with surface temperatures ranging from 7.42℃ to 11.59℃; 4) SEPES installations significantly reduce daily heat loads, with ceiling installations achieving the highest energy-saving rate of 49.7%. Overall, ceiling installations are most effective, followed by the north wall, floor, south wall, east wall, and west wall.
