Optimal Domestic Solar Space and Water Heating System in Cesme

Abstract

Solar hot water and space heating systems have been an important energy conservation technique in buildings, along with improving insulation efficiency of building envelopes and HVAC systems. According to statistical data from EU, installations of solar hot water heating systems have been increased gradually. The purpose of this study is to illustrate quantitatively the feasibility of optimal space and water heating system using solar energy. The house is assumed to be located in Cesme, Turkey, where 1304 kWh/m(2)-year of solar radiation for the period of 2734 h/year is measured. Considering the space heating and hot water demand in this geographic location, solar collector and storage capacity are optimized using f-Chart method. The results showed that a 92% of the total energy demand can be covered by solar energy.
