Application and evaluation of energy enthalpy heat exchanger
Jetelina, Michal ; Horák, Petr (referee) ; Uher, Pavel (advisor)
This master thesis is solving measuring the efficiency heat recovery and application unit, which includes heat recovery into selected building. In the first part of the thesis are analy-zed the different types of heat recovery system, their behavior and suitability of use in HVAC systems. The second part includes the actual experiment, when were measured parameters of air, which passed through the unit and then were analyzed the results. In the last part, third, was measured unit applied to the selected house and was compared to operation of the unit in case of use by the producer given unit parameters and measured parameters.

Cooperation of heat pump with passive solar system
Bohůn, Vojtěch ; Králová, Zuzana (referee) ; Mastný, Petr (advisor)
This bachelor thesis deals with alternative energy sources – a solar system and a heat pump. Their operation is energy-advantageous and they can be efficiently connected in one system. The focus of this thesis is firstly to give an overview of kinds, function, properties, constructional elements and usual arrangements of active and passive solar systems and heat pumps in connection with heating of buildings, secondly to suggest a connection of a combined heating system with a heat pump and of a passive solar system and to evaluate it from an energetic and economic point of view. Firstly, a basic theory for calculation of quantity of electrical energy absorbed by a surface is introduced. Then, a categorization and construction of active and passive systems are presented. Hereafter, advantages and disadvantages of single solar systems are described and basic calculation relations for determination of a heat gain and of proportions of passive solar systems are showed. Subsequently, the function of a heat pump is analyzed, the categorization of its kinds according to the relevant criteria is given and its basic functional elements, typical properties and means of possible use are described. On the basis of gained knowledge, conditions of cooperation of a heat pump with a passive solar system are summarized and substantiated. According to these conditions and to the construction of an object, a combined system is designed for, a connection of a system with a heat pump air / water, a heat accumulator and a recuperative unit is constructed. Consequential calculations evaluate energetic needs of an object and heat gains of a passive solar system. They serve as a basis for a concept of heat source and for determination of an energy balance. A total annual heat need is 13914,7 kWh. It was compared with the case when the object was equipped with standard-size windows. The comparison shows that a passive solar system can spare roughly one third of total annual heat consumption. From the measurement on the object is determined, when a passive solar system is able to supply a heat pump with heat. After that, the suggested system is evaluated from an economic point of view: it is compared with other possible heat sources by the method of net present value. It can be said that solid fuel firing and gas firing are economically more advantageous than the use of a heat pump. The reasons are particularly high initial costs and in case of wood firing also its low price. In conclusion, the gained results are summarized.

Indirect air heating
Beneš, Josef ; Adam, Pavel (referee) ; Počinková, Marcela (advisor)
The master Thesis deals with indirect air heating in air handling units. In the theoretical part of the thesis the categories of heat exchangers are defined according to their positioning in ventilation system, used material and type of heat transfer fluid. To the issue of calculating heat exchanges through heat exchangers and description of different kinds of regulation of primary heat transfer fluid is dedicated a separate chapter. The experimental part of the thesis deals with determining performance of current air heat exchanger at set thermal gradient with various heat transfer fluids. In the calculating part of the Thesis, based on measured values, are suggested two possible solutions for use of technological waste heat. Final evaluation of particular solutions was based on the criterion of efficiency usage and implementation investment costs.

Heating the house with "nearly zero" energy consuption
Lacina, Martin ; Hořinková, Lucie (referee) ; Horák, Petr (advisor)
The main content of this master thesis is the proposition for the heating of a multi-purpose building. The aim of this project is to find the best way how to manage heating with "nearly zero" energy consumption. In the first part of the thesis there is a description of currently the most common systems leading to energy savings. The second part consists of three possible technical alternatives, containing technical solutions for this particular building with the regard to the requirements of the task. The third part then consists of the chosen solution.

Airconditioning in a sanatorium
Batelka, Václav ; Andrys, Petr (referee) ; Rubina, Aleš (advisor)
Bachelor thesis describes the design of airconditioning for sanatorium in the village Liptal. The building is used for the rehabilitation of the treatment of Alzheimer´s deisease. The main task is to ensure the required exchange of fresh air and exhaust moisture loads from the interior. The swimming pool was further ensure coverage of heat loss in winter and heat gain in the summer. The device is designed to meet all hygienical, operational and functional requirements according to applicable legislation. In the theoretical part, the issues of water evaporation from the water surface. Calculation and design of the proposal addresses the specific design of airconditioning for equipment to operate the pool, electrotherapy and clubhouse. Result of this work is the design documentation for these aircondition equipment.

Heat exchangers for heating
Blažek, Miroslav ; Hejčík, Jiří (referee) ; Jaroš, Michal (advisor)
The Heat exchangers are important part in the energy transfer between two substances. Bachelor’s thesis deals with the problems of the option of the heat exchangers. It seperated into two parts. In the first theoretic part there are shown the basic criteria of this option. The next part deals with the most frequent types of usage of heating units or convectors.
