Theoretical Calculation of Heat Losses of Heat Exchangers to Vicinity

Abstract:

This contribution is focused on heat exchangers and their heat losses dispersed into vicinity. In the introduction of the contribution this loss heat flow of heat exchangers is analysed into basic physical processes and with applying simplifying assumptions it is described by a computational equation suitable for technical practice. The result of the study is the confirmation of the general fact that the quotient of losses heat into vicinity with regard to the transferred heat flows in the heat exchanger is insignificant.
