Heat exchanger design for waste air heat recovery
Valentová, Helena ; Toman, Filip (referee) ; Baláš, Marek (advisor)
The master’s thesis deals with heat recovery from waste air in a multifunctional hall. The thesis contains a theoretical part that shows required parameters of an indoor environment, a composition of an air handling unit and a description of its individual parts suitable for this purpose. Subsequently a design calculation of a rotary heat exchanger and a plate heat exchanger is made. The calculation contains geometry, heat transfer and pressure drop. Then the heat exchangers are compared and a more suitable option for this application is chosen. Further the thesis includes drawing documentation of both types of heat exchangers.

Analysis of different means of heat recovery in ventilation
Dvouletý, Tomáš ; Krejčí, Vladimír (referee) ; Charvát, Pavel (advisor)
Bachelor´S thesis contains summary and expplanation of basic ideas related with topic of analysis of different means of heat recovery in ventilation like efficiency, economy of using atc. Main part of the work is dividing varied ways of heat recovery based on kind of used heat exchanger. There are description of principle of heat transfer with illustrative pictures including some other informations related to each heat exchanger. After that there is comparation of heat exchangers based on efficiency, enthalpy transfer capability and safety. This part also includes summary of advantages and disadvantages. Finaly there are brief report of market with heat exchangers in Czech republic and some others ways how to use gained heat.

Design a AHU unit with respect to the heat recovery system
Otava, Jiří ; Blasinski, Petr (referee) ; Rubina, Aleš (advisor)
This diploma thesis is focused on problems of heat exchangers. There are two main objectives. The first objective is based on long-term measuring of enthalpy heat exchanger, processing of measured data and comparison of result with manufacturer's results. The second objective is design of variant solutions for two types of heat exchanger of air conditioning unit of selected shop. For variant without moisture transportation was selected cross flow exchangers. Thanks to knowledge from long-term measurement, was selected enthalpy heat exchanger for variant with moisture transportation. Chosen variants were compared with emphasis on heat and moisture exchange efficiency with requirements on Ecodesign.
