34% of the energy consumption in Turkey belongs to buildings
and around 85 % of this consumption is utilized for heating purposes. The
operating characteristics of the HVAC systems in buildings directly affect both
the building's thermal comfort and energy consumption. This study aims to
determine the effect of operating conditions of the HVAC system on thermal
comfort and energy consumption of residential buildings. For this purpose, the
HVAC system for a 100 sqm residence in İzmir city has been investigated
according to the single and double temperature set values at continues and
intermittent operating modes for fully mechanically control or natural
ventilation conditions.

Thermal comfort satisfaction is expressed by PMV value. In
this context, primarily the set temperatures of the HVAC system are determined
for PMV = 0 which represents the best case of thermal comfort by  using Design Builder software. Annual
specific heating/cooling energy consumption, annual primer specific energy
consumption, hourly PMV values during occupancy hours and statistical evaluation
of these PMV values of a residential house are realized for considered 5
different operating conditions of HVAC system by using determined temperature
set values. According to the obtained results, among 5 cases, the case with
fully mechanical controlled, continuous regime, 
monthly dual heating/cooling operative set values, provides the maximum
thermal comfort for normal expectation level of the thermal comfort with a
cumulative frequency of 99,6%. The case, with fully mechanical controlled,
intermittent regime,  monthly single
heating/cooling operative set values, consumes the minimum energy with specific
satisfaction energy consumption of 2,04 kWh/m²/%KF.

Isıl Konfor Sıcaklıklarına Bağlı Olarak Bir Konutun Enerji Performansının Değerlendirmesi: İzmir Örneği

Öz

 Türkiye’de
enerji tüketiminin yaklaşık %34’ü binalarda ve bunun %85 kadarı da ısıtma ve
soğutma amaçlı kullanılmaktadır. Binalarda bulunan HVAC sistemlerinin işletme
özellikleri, hem binanın ısıl konforunu hem de enerji tüketimlerini doğrudan
etkilemektedir. Bu çalışmada, HVAC sistemlerinin işletme şartlarının, ısıl
konfor koşulları ile enerji tüketimlerine olan etkisinin belirlenmesi
amaçlanmaktadır. Bu amaçla İzmir ilindeki 100 m²’lik bir konut için
öngörülen HVAC sisteminin kesikli ve sürekli rejimde, tek ve çift sıcaklık set
değerleri ile tam mekanik kontrollü veya doğal havalandırmalı olarak
çalıştırılması durumları incelenmiştir.

 

Isıl
konfordan olan memnuniyet PMV değeri ile ifade edilmektedir. Bu kapsamda
öncelikle, Design Builder yazılımı kullanılarak en iyi duruma karşılık gelen
PMV=0’a göre HVAC sisteminin set sıcaklıları belirlenmiştir. Bu sıcaklık set
değerlerinin kullanılması ile ele alınan 5 farklı durumda konut için yıllık
birim ısıtma/soğutma enerji tüketimleri, birim birincil enerji tüketimi, yıl
boyunca ailenin evde bulunduğu saatlerde sağlanan PMV değerleri ve PMV
değerlerinin istatistiksel değerlendirilmesi gerçekleştirilmiştir. Elde edilen
sonuçlara göre, incelenen 5 durum arasında normal beklenti seviyesinde % 99,6
kümülatif frekans yüzdesi ile ısıl konforu en çok sağlayan tam mekanik
kontrollü, sürekli rejim, aylık çift ısıtma/soğutma operatif sıcaklık set
değerli durumdur. Tam mekanik kontrollü, kesikli rejim, aylık tek
ısıtma/soğutma hava sıcaklığı set değerli durum ise 2,04 kWh/m²/%KF
birim memnuniyet enerji tüketimi değeri ile en az enerji tüketen durum
olmaktadır.
