Öğe Optimum insulation thickness assessment of different insulation materials for mid-latitude steppe and desert climate (BSH) region of India(Journals & Books, 2021-01) Kallioğlu, Mehmet Ali; Sharma, Ashutosh; Chinnasamy, Veerakumar; Chauhan, Ranchan; Singh, TejOne of the most effective techniques that is used for energy wastage in buildings is heat insulation. It is possible due to this application to minimize the fuel quantity and accordingly tolerate toxic emissions by finding the optimum point that gives the maximum efficiency. This study was conducted for Jaipur province in Indian climate geography. Climatic characteristics of the region are Mid-Latitude Steppe and Desert Climate (Bsh). Energy need and heat losses in exterior wall were determined by accepting cooling degree day value as T > 24 °C. Optimum insulation thickness, payback period, annual return and annual return rate for XPS and EPS of two different insulating materials respectively are 0.0383–0.0731, 2.35–1.79, 10.95–12.92, 46.84–37.25.Öğe Determination of optimal insulatıon thickness in cooling for Diyarbakır city(Dicle University, 2016) Kallioğlu, Mehmet Ali; Avcı, Ali Serkan; Ercan, UmutIncrease in population and rapid technological progress as the similar energy sources are declining day by day. This situation affects the economic development negatively, which countries are energy dependent outside. Therefore, these countries, including Turkey, determine their energy strategies, productivityoriented policies need to be considered. The savings obtained by insulation will be an additional benefit to the users and therefore to the economy of the country. It is possible to reduce the amount of fuel used and determine the energy to be used as the result of determining the optimal efficiently point where the cost is reduced the most while the cooling is obtained while the cooling is being insulated. The cost of insulation while cooling is minimized, as well as maximum efficiency, reduction of the energy consumption used in the determination of the optimum point can be obtained. In this study, using the life-cycle cost analysis (LCCA), the optimum insulation thickness, annual energy saving and pay-back period analysis were carried out in area cooling at 22 C 0 for Diyarbakır province. Diyarbakir for extruded polystyrene (XPS) used when the optimum thickness of 0.0277 (m), 63.66% annual gain, payback period of 3.13 (years). Expanded polystyrene (EPS) in optimum thickness 0,037 (m), 47.10% annual gain, payback period of 2,069 (years) where such parameters.Öğe Empirical modeling between degree days and optimum insulation thickness for external wall(Taylor & Francis, 2020-03) Karakaya, Hakan; Kallioğlu, Mehmet Ali; Ercan, Umut; Avcı, Ali Serkan; Fidan, CihatInsulating is the most effective method that is used to save energy in buildings. Samples from cities from different climatic zones from TS 825 (Turkey) first. Optimum insulation thickness () analysis is based on two types of insulating and four different fuels (natural gas, coal, fuel oil and electric) of related cities. Cost accounts, payback period and CO2-SO2 emission calculations were performed based on these analyses. Second of all, the relationship between a number of degree day (NDD) and optimum insulation thickness () was developed by linear, quadratic and cubic correlations. Thirty different mathematical correlations based on different fuel types by using XPS and EPS insulating materials. Twenty-four of these models that were developed were generated peculiar to the fuel type; six of them were generated based on average insulation thickness. R2 values of related correlations are between 0.9989 most and 0.9952 at least as well as it is pretty close to (R ≤ 1) one value. The model among these models is the cubic mathematical model that gives the best average value. a = 0.0036, b = 5E-05, c = – 7E-09 and d = 6E-13 are the values for XPS material. Following values are for EPS material; a = 0.0028, b = 5E-13, c = – 7E-09 and d = 4E-05. R2 determination coefficient of both two equations is pretty close to 0.9989 and 1; the models obtained are less-than-stellar. Optimum insulation thickness of the area can be known based on the type of material via the number of degree day without the need for long analyses. According to the R2 values, the use of all models is recommended for academic and industrial users.Öğe Environmental and economic analysis of optimum heat insulation thickness in energy saving(European Journal of Technique (EJT), 2016-08-01) Karakaya, Hakan; Kallioğlu, Mehmet Ali; Arca Batı, Zülal; Durmuş, AylaDeveloping technology and increasing population cause the natural energy resources rapidly. This has compulsorily forced the countries such as Turkey, which import almost all energy needs and use great deal of it in home heating, to save energy. It will provide benefits for users, indirectly the economy of the country, with saving obtained from insulation. One of the most effective methods attaining gain of energy is heat insulation. While heat insulation is carried out, by determining the optimum efficiency point, the amount of fuel used decreases, which leads to cost reduction and highest efficiency level. Therefore, it is possible to tolerate harmful emissions. In this study, optimum insulation thickness, total cost, energy saving, duration of pay-back and environmental analysis for heating were conducted in Diyarbakır by utilizing different fuel and insulation types. When extruded polystyrene (XPS) was used, average optimum thickness was 0,0675 (m), annual return was 62,165%, duration of pay back was 1,83 (years) and CO2 and SO2 emissions were 76% lesser. When expanded polystyrene (EPS) was used, the parameters such as average optimum thickness 0,0825 (m), annual return 73,06%, duration of pay back 1,245 (years) and CO2 and SO2 emissions 85% lesser.Öğe Environmental and economic analysis of optimum heat insulatıon thickness in energy saving(Dicle University, 2016) Kallioğlu, Mehmet Ali; Karakaya, Hakan; Arca Batı, ZülalDeveloping technology and increasing population cause the natural energy resources rapidly.
