Binalarda bulunan HVAC sistemlerinin işletmeözellikleri, hem binanın ısıl konforunu hem de enerji tüketimlerini doğrudanetkilemektedir. Bu çalışmada, HVAC sistemlerinin işletme şartlarının, ısılkonfor koşulları ile enerji tüketimlerine olan etkisinin belirlenmesiamaçlanmaktadır. Bu amaçla İzmir ilindeki 100 m2’lik bir konut içinöngörülen HVAC sisteminin kesikli ve sürekli rejimde, tek ve çift sıcaklık setdeğerleri ile tam mekanik kontrollü veya doğal havalandırmalı olarakçalıştırılması durumları incelenmiştir.Isılkonfordan olan memnuniyet PMV değeri ile ifade edilmektedir. Bu kapsamdaöncelikle, Design Builder yazılımı kullanılarak en iyi duruma karşılık gelenPMV=0’a göre HVAC sisteminin set sıcaklıları belirlenmiştir. Bu sıcaklık setdeğerlerinin kullanılması ile ele alınan 5 farklı durumda konut için yıllıkbirim ısıtma/soğutma enerji tüketimleri, birim birincil enerji tüketimi, yılboyunca ailenin evde bulunduğu saatlerde sağlanan PMV değerleri ve PMVdeğerlerinin istatistiksel değerlendirilmesi gerçekleştirilmiştir. Elde edilensonuçlara göre, incelenen 5 durum arasında normal beklenti seviyesinde % 99,6kümülatif frekans yüzdesi ile ısıl konforu en çok sağlayan tam mekanikkontrollü, sürekli rejim, aylık çift ısıtma/soğutma operatif sıcaklık setdeğerli durumdur. Tam mekanik kontrollü, kesikli rejim, aylık tekısıtma/soğutma hava sıcaklığı set değerli durum ise 2,04 kWh/m2/%KFbirim memnuniyet enerji tüketimi değeri ile en az enerji tüketen durumolmaktadır. KW - ısıl konfor KW - enerji tüketimi KW - PMV KW - Fanger KW - Adaptif metod N2 - 34% of the energy consumption in Turkey belongs to buildingsand around 85 % of this consumption is utilized for heating purposes. Theoperating characteristics of the HVAC systems in buildings directly affect boththe building's thermal comfort and energy consumption. This study aims todetermine the effect of operating conditions of the HVAC system on thermalcomfort and energy consumption of residential buildings. For this purpose, theHVAC system for a 100 sqm residence in İzmir city has been investigatedaccording to the single and double temperature set values at continues andintermittent operating modes for fully mechanically control or naturalventilation conditions.Thermal comfort satisfaction is expressed by PMV value. Inthis context, primarily the set temperatures of the HVAC system are determinedfor PMV = 0 which represents the best case of thermal comfort by using Design Builder software. Annualspecific heating/cooling energy consumption, annual primer specific energyconsumption, hourly PMV values during occupancy hours and statistical evaluationof these PMV values of a residential house are realized for considered 5different operating conditions of HVAC system by using determined temperatureset values. According to the obtained results, among 5 cases, the case withfully mechanical controlled, continuous regime,monthly dual heating/cooling operative set values, provides the maximumthermal comfort for normal expectation level of the thermal comfort with acumulative frequency of 99,6%. The case, with fully mechanical controlled,intermittent regime, monthly singleheating/cooling operative set values, consumes the minimum energy with specificsatisfaction energy consumption of 2,04 kWh/m2/%KF.
