Radyant sistemler geleneksel ısıtma
ve soğutma sistemlerine göre daha iyi ısıl konfor şartları sağlamalarının yanında
düşük enerji tüketimleriyle de ön plana çıkmaktadırlar. Radyant panel
sistemlerinin enerji ve ekserji açısından gösterdikleri performanslar dünya
çapında akademisyenlerin ilgisini çekmiştir. Bu çalışmada, duvardan radyant
soğutma sisteminin ısıl konfora etkisi sayısal olarak incelenmiştir. Bu amaçla
yapılan çalışmalarda radyant panellerin içerisinde bulunan soğutucu akışkan
sıcaklığı sırasıyla 18°C, 20°C ve 22°C tanımlanarak sonuçlar PMV-PPD
parametrelerine göre karşılaştırılmıştır. Tüm durumların ASHRAE 55 standardında
belirtilen ısıl konfor şartlarını sağladığı, en iyi ısıl konfor değerine yakın
durumun 20°C soğutucu akışkan sıcaklığında gerçekleştiği görülmüştür.

Investigation of Coolant Temperature Effect on Thermal Comfort in Wall Mounted Radiant Cooling Systems

Öz

Radiant systems provide better thermal comfort
conditions than traditional heating and cooling systems, as well as low energy
consumption. The performance of radiant panel systems in terms of energy and
exergy have attracted the attention of the academicians around the world. In
this study, the effect of the wall mounted radiant cooling system on thermal
comfort was investigated numerically. For this purpose, the coolant temperature
inside the radiant panels was defined as 18°C, 20°C and 22°C respectively and
the results were compared according to the PMV-PPD parameters. It has been
found that all cases fulfilled the thermal comfort conditions specified in
ASHRAE 55 standard and the best conditions were obtained at 20°C water
temperature.
