The aim of this diploma thesis is to get acquainted with modern technological elements currently used in shell-and-tube heat exchanger in the shell-side and tube-side, thermal-hydraulic calculation of selected elements and comparison of thermal-hydraulic properties with classically used competing technological elements. The work deals mainly with EM baffle in the tube-side and tube inserts like the twisted tape type (and its modifications) and coiled wire in the tube-side. The theoretical part is focused on acquaintance with classical technological elements in shell-and-tube heat exchanger and with basic thermal-hydraulic calculations, practical part then on acquaintance with modern elements and thermal-hydraulic calculation of selected elements. These calculations are then compared with the results of the thermo-hydraulic calculation of similar elements.

The diploma thesis processes project documentation in the stage of construction for modernization of an apartment house near the center on the street Vlhká 22 in Brno. The building is divided into four residential floors and nonresidential basement and attic. On the first floor there are two residential units and the other four residential units. The foundation structures are made of solid bricks. The vertical load-bearing and non-load-bearing structures are also made of solid bricks. Exceptionally drywall partitions. In the basement, the ceiling structures are made of brick barrel vaults, above the above-ground floors there are wooden beamed ceilings. The roof structure of the building is made of purlin system with standing stool and covering of ceramic roof tiles. Three additional housing units will be built in the attic. In the basement, the masonry will be undercut by a chain saw, partly by pressure grouting and partly by a new layer with a waterproofing layer. All wood-beamed ceilings will be replaced with prefabricated ceiling beams with aerated concrete inserts without overhead slab. The garden part of the building will be insulated with mineral wool. The roof structure will be constructed from the street side as a shed roof and in the garden part a flat roof with a gradient layer of expanded polystyrene thermal insulation and a waterproofing layer of thermoplastic poleolefin.
