Use of secondary heat ventilation air in multifunctional building
 Dvořák, Jan ; Adamovský, Radomír (advisor) ; Neuberger, Pavel (referee)
This work deals with the theme of heat recovery from waste air and moisture recovery in residential areas. In a brief introduction, introduces the reader to various aspects of the energy system of choice due to the location and method of application equipment for heat recovery. In the following chapters is described theoretically transfer heat exchanger and determination exchanger efficiency, along with the search components including the basic distribution of each kind secondary heat recovery coils. Part of the theory is evaluating the effectiveness of the use of heat recovery equipment. The second part is solved draft multipurpose building consisting of a concert hall and the administrative section of the building. According to the resulting requirements for air-conditioning equipment has been selected with the described type of heat exchanger. Follow economic evaluation facility and the conclusion. The attachment is plan with a description of the location of equipment in the building.

Utilization of secondary heat ventilation air stables for breeding of broiler chickens
 Koubek, Radek ; Adamovský, Radomír (advisor) ; Polák, Martin (referee)
The goal of this thesis was to propose and evaluate the effectivity of a heat recovery system from ventilation air in a farm for broiler chickens. That was supplemented by an analysis of the needs of chickens in respect to their requirements on air exchange and also by a description of heat recovery methods. Subsequently the calculation, according to Czech regulations, of the need for heat is examined including the description of each element of the heat-balance equation. A heat recovery system is designed based on the calculations and parameters necessary for the evaluation of the annual expenses are defined. Then an amount of batches is planned out into the course of one year and based on that the annual heat consumptions are compared for the option with and without heat recovery systems. The return of the investment, profitability and a total financial profit over the heat recovery systems lifespan are determined from the difference of annual expenses.
