Cascade Boiler Houses of System Regulation
Smola, Vojtěch ; Rubinová, Olga (referee) ; Formánek, Marian (advisor)
This bachelor’s thesis is about designing cascade of condensing boilers and regulation for four storey house with unheated basement. Cascade consists of three condensing boilers that are controlled by the three-zone weather-compensated control. Heating systém is controlled via shung circuit with electronically controlled mixing valves. The heating system is designed to ensure the smooth function of the heating systém and the boiler operates as the largest part in condensing mode. In this thesis were designed mixing control units and control valves to operate across the range. The proposed heating system meets the requirements for housing corresponding to European standards.

Optimization of heat generators for residential house
Smola, Vojtěch ; Horák, Petr (referee) ; Formánek, Marian (advisor)
This diploma thesis solves design of heating in a residental building. This work is focused on the selection of appropriate one of the two options a heat source, which are cascade heat pumps ground-water and gas condensing boilers. The theoretical part of the diploma thesis deals with introducing to the issue of heat pump systems. The functional principle of the widely most used types and particularized type ground-water. In the practical part calculation and design of heating system with selected heating source that is cascade of gas condensing boilers.

Empirical analysis of the effectiveness of English Premier League football clubs in the 2019/20 season
Smola, Vojtěch ; Gregor, Martin (advisor) ; Vávra, Jan (referee)
This paper focuses on an empirical analysis of the efficiency of English Premier League football clubs. Scholarly papers, that have focused on this topic previously, have reached different conclusions. The aim of this thesis is to show whether clubs manage to spend their finances efficiently or not, and furthermore to identify the most efficient teams. For this purpose, we have used data from 2019/20 season. We focus on club expenditure (players' and other staff salaries, advertising, new player purchases) and income (tickets, broadcasting rights, sponsors and how many points they earned in this season. We will also take note of the capacity of the stadium. The method used was data envelopment analysis with the CCR model, which is input-oriented, and the BCC model, which uses variable returns to scale, as they are the most appropriate for this purpose. The results show that big clubs or teams successful internationally are not more efficient than other league teams. The inefficiency is primarily due to poor use of resources, but also by the global pandemic of Covid-19.
