Experimental investigation of ground source, solar source and air source heat pump for domestic heating in Elazığ

ABSTRACT PHd Thesis EXPERIMENTAL INVESTIGATION OF GROUND SOURCE, SOLAR SOURCE AND AIR SOURCE HEAT PUMP FOR DOMESTIC HEATING IN ELAZI? Firat University Graduate School of Natural and Applied Sciences Department of Mechanical Education 2004, Page: 200 An experimental a heat pump set-up was constructed for domestic heating by adding of ground source, solar source and air source in Elazığ. The experimental set-up consist of six plate solar water collectors, one heating water tank, two plate type water evaporators, two circulation pumps, one air source evaporator and auxiliary apparatus was used during measurements. In this study, heat pumps with solar source, air source and ground source were investigated. In addition, experiments were performed with combination of solar source, air source and ground source heat pump too. The experiments were conducted in heating season of 2002-2003 from December to March. In the first chapter of this study, the importance of subject was introduced and emphasized. In the second chapter, the place of subject in the current literature was mentioned. Carnot heat pump cycle was explained in the third chapter. The experimental set-up was introduced in next chapter. The measurement methods were presented in fifth chapter. The investigated heat pump systems were given in the sixth chapter. The experimental results were given in chapter seven. The economy analysis was made in chapter eight. In the last chapter, the results of experiments were discussed and suggestions were presented. Finally, The Performance Coefficient the system, the instantaneous efficiency of the solar collector, the exergy losses and economic analysis of the system were evaluated. From the economical analyses, it was understood that ground source heat pump is the most economical system among all heat pump systems in Elazığ.
