Thermoeconomical analyses of solar heating and cooling systems in a detached house

In this thesis, the annual heating and cooling loads of a building located in Antalya region were met with solar assisted absorption chiller system and the economic analysis of the application was investigated. During the study, design of heating and cooling systems adhered to related standards and regulations. Heating and cooling loads were all calculated and the necessary equipment were selected. The investment cost of the installed system was calculated in comparison to the conventional systems and the life cycle save analysis of the system was investigated with a low-interest credit system. The insulation requirements of the building was done acoording to TS standards called Heat Insulation Rules in Buildings. The heat loss and gains of the building were calculated using the FineHVAC Program. In the study, EN12831 method, compulsory in Europe, for the calculation of heat loss and CLTD method for the calculation of heat gain have been utilized. Moreover, the Ø-f chart" method and P1,P2 method were used for collector area-solar fraction calculations and thermoeconomic analysis, respectively. Detailed market research was conducted for the supply of products and labor in the investment cost accounts. Mechanical systems are designed with AutoCAD drawing program and summary tables were prepared according to findings. In the light of materials and methods, the heating load of the building was calculated as 20.5 kW and the cooling load was calculated as 40.3 kW. The calculations showed that 36% of the total utilization was achieved by using a 40 kW solar absorption chiller assisted with 125 m2 solar collectors. As a result of the economic analysis, it was seen that the investment cost amounting to 394.000,00 TL has been positive for the 16th year through the credit system.
