Mužila, Martin ; Baláš, Marek (referee) ; Pospíšil, Jiří (advisor)
The work is focused on area of exchanging steam distribution net for hot water one, in central distribution net of Martin’s heating plant. The main subject, which talks about pros and cons in this exchange process, is determination of heat losses which are created on heat distribution net during different operating status. These heat losses are calculated and on their basis some conclusions are concluded. Moreover, new heat exchanger is designed for certain conditions and also mathematical model of distribution net is created, which is suitable for checking different operating status. As a result of the work is technic’s and economic’s analysis of this project.
