Performance analysis of a PVT integrated heat pump system working with CO2

The human population in the world and in our country is continuously increasing. As a natural consequence of this increase, the consumption of sources is also increasing. The primary contributor to the increasing consumption is the need for energy. Many of the limited and decreasing energy resources on earth cause harm to the planet with their use. In order to meet the increasing need of the world, energy resources tend to be obtained in more environmentally friendly and sustainable ways as a manifestation of developing consciousness and technologies. Thanks to these preferred environmental and sustainable energy sources, a reduction in environmental pollution and a slowdown in global warming are achieved. Solar energy is one of these environmental sources. In this thesis, a system design and theoretical analysis have been made to meet the heating and electrical energy needs of a house designed with a hybrid heat pump with PVT and environmentally friendly CO2 fluid. In the first stage, the heating energy need of the house designed in the study was determined. Afterward, the thermal and electrical analyzes of the PVT were modeled. Finally, the thermodynamic analysis of the heat pump was carried out. As a result of these analyzes and determinations made specifically for the designed system, findings in many parameters were obtained by comparing the system with both CO2 fluid and different fluids. The obtained findings are given in the thesis in graphic and chart formats comparatively.
