The theme of the Doctoral Thesis is “Photovoltaic Solar Air Conditioning” (PV-SAC). The objective of this study is to develop, to test and to evaluate the technology of the enhanced grid-connected photovoltaic solar air conditioning. Ever-decreasing costs of system components combined with energy-efficient concepts in the area of solar energy technologies open new opportunities for application of hot- and cold-storage systems in different building sectors. In the current market situation, photovoltaic electric-driven compression chillers are more profitable as compared with solar thermal-driven sorption cooling devices due to a smaller size of their components such as compressor and heat rejection unit. In the research, a concept has been developed for the solar air conditioning system operating on PV electric energy, in which cooling by a compression chiller is combined with free cooling. The PV-SAC system is intended for a single-family house. The definition and analysis of the working parameters and of the system yield are presented. The PV-SAC research has been carried out in two parts: 1. Dynamic simulation of a system model (for three different climatic zones) in the Polysun® program software. 2. A real system operation in a temperate climatic zone. The system is compared with that based on the sorption solar air conditioning technologies. The research results have been reported at 11 international scientific conferences and are described in 28 publications. The Doctoral Thesis consists of five chapters; it has been illustrated by 63 figures and 6 tables, and its volume is 105 pages. In the Thesis, 51 literature sources have been used.
