Theoric and experimental analysis of ground sourced heat exchangers

This work includes the analysis of the experimental data that obtained by working the Ground Sourced Heat Pump founded at Davutpaşa Campus of Yıldız Technical University. Expriment mechanism includes undergrounded piping system which consist of Plastic and Aliminium winded types of pipe. Both type of pipe are seperated pipe line under the ground.Heat transfers at the pipes are examined by making heat pump work. Analysis has been made by comparing two models. Constant surface temperature, KOYUN model and linear source teori has been used for heat analysis of the pipes. At the beginning, the importance of Ground Sourced Heat Pump has been explained and then Ground Sourced Heat Pump system has been introduced in detail. After that, experimantal mechanism has been introduced and calculations has been done. In conclusion. The efficiency of the pipe has been compared and investment cost studied.Keywords: Thermoeconomic optimization, Ground Sourced Heat Pump, Ground heat exchanger, Parallel pipe horizontal ground heat exchanger,
