Cooling residential spaces by using solar energy
Staněk, Martin ; Rapta, Patrik (referee) ; Pech, Ondřej (advisor)
The bachelor thesis focuses on the design of the cooling of a residential unit in an old family house. The introductory chapter deals with the description of the air conditioning equipment and its use. The following section discusses the functions and possibilities of photovoltaic systems to reduce the economic cost of air conditioning. The third chapter discusses the parameters of the building structure. The following chapter shows an example calculation and results of the heat gains of all rooms. The penultimate chapter shows the cooling design of the dwelling unit including an additional hot water storage tank, for a higher utilization of the outdoor unit. The last chapter will show the design of a photovoltaic plant on the roof of the building to minimize the economic burden of the air conditioning operation.
Wall-Hung Heat Pump
Foltys, Jan ; Rapta, Patrik (referee) ; Hejčík, Jiří (advisor)
This thesis deals with the design and analysis of a wall-hung air/water heat pump that has the potential to replace existing wall-hung gas boilers in households. The thesis includes a detailed analysis of the principles of heat pump operation, an evaluation of existing technologies on the market, and the design of a new system. The thesis also extends to the optimization of the evaporator chamber, which is part of the design. It included CFD simulation, experimental verification, and design modifications were carried out. The results show that a properly designed heat pump can be an efficient alternative to traditional gas boilers, contributing to decarbonization and improved energy efficiency.
