Havalı Güneş Kollektörlü Bir Isıtma Sisteminin Deneysel Olarak İncelenmesi

Abstract

Bu çalışmada, Diyarbakır ilinde bulunan bir güvenlikçi kabininin güneş enerjisinden yararlanılarak ısıtılması amaçlanmıştır. Kabin içi sıcaklık, referans sıcaklığı olan 21°C’nin altına düştüğünde ısıtma işlemi yapılmıştır. İmal edilen güneş enerjisi depolamalı bir ısıtma sisteminde iki adet düzlemsel havalı güneş kolektörü, ısı deposu kullanılmıştır. Güneş enerjisi, içerisinde 260 adet 1.5 lt’lik su şişesi bulunan ahşap duvarlı ve polietilen köpüğüyle yalıtılmış bir ısı deposunda depolanmaktadır. Isıtma ihtiyacı olduğunda, ısı deposundan çekilerek kabinin ısıtılması sağlanmaktadır. Bu çalışmada, bu sistemin enerji ve ekserji analizi yapılmıştır. Isı deposunda depolanan günlük ortalama ısı ve ekserji miktarları sırasıyla 2.15 kW ve 386 W elde edilmiştir. Ortalama günlük net enerji ve ekserji verimlerinin sırasıyla %83 ve %55.3 olarak bulunmuştur. Ayrıca, ısı deposundan geri kazanılan ortalama günlük ısı ve ekserji miktarları sırasıyla 2.25 kW ve 725 W olmuştur.

Experimental Investigation of a Heating System with Air Solar Collector

Abstract

In this study, it is aimed to heat a security cabinet in Diyarbakir by using solar energy. Heating was performed when the cabin temperature fell below the reference temperature of 21°C. In a solar energy storage heating system, two flat plate solar collectors and a heat store were used. Solar energy is stored in a heat storage with wooden walls and insulated with polyethylene foam. 260 plastic water bottles, each 1.5 l were lined horizontally into the storage tank. When there is a need for heating, the cabin is heated by withdrawing heat from the heat storage. In this study, the energy and exergy analysis of this system was made. The average daily rate of the heat kept inside the heat store was 2.15 kW and thermal exergy rate was 386 W. The average mean energy efficiency and exergy efficiency were obtained as 83% and 55.3%, respectively. The average daily heat rescued from the heat store was defined as 2.25 kW and thermal exergy was 725 W.
