The main content of the bachelor's thesis is the solution of heating for a multifunctional building. The thesis is divided into three parts: theoretical, computational, and design parts. The theoretical part focuses on heat substations. The computational part is dedicated to the design of heating and hot water preparation for the multifunctional building. The building houses a dental hygiene office, administrative spaces, a shop, staff lounges, and storage areas. The building is heated using panel radiators and bench convectors. The heat source is provided by a heat substation connected to a central hot water supply system. The heat substation is thermally independent and is equipped with plate heat exchangers for both the heating system an...
