Performance simulation of a solar PV system for a single-family home
Veličková, Kateřina ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
Recently, renewable energy resources have become an urgent issue, as a result there are many papers focused on photovoltaic power plants and their performance simulations. These simulations not only allow us to assess the reduction of dependency on the fossil fuels, but also to calculate costs saving. This work considers the operation of a single-family house in the Czech Republic. However, a summary of photovoltaic potential factors is presented as well as the most common applications used for performance simulations of photovoltaic power plants. In practical part of this work, the load profile for common household is determined based on the data provided by the Energy Market Operator, alternatively the load profiles of two households owning a plug-in hybrid are also determined. The performance simulation is assembled in TRNSYS application and the results are summed up in the last chapter.

Simulation of heating and cooling loads of the A1 building and the analysis of energy saving measures
Bartoník, Adam ; Kolbábek, Antonín (referee) ; Charvát, Pavel (advisor)
This thesis deals with the heat loss and the heat loads simulation of A1 building in the area of The Faculty of Mechanical Engineering, Brno University of Technology and with the measures of the energy saving. The measures of the thermo-technical charakteristics for the winter and summer operations are provided on the base of the current state simulation. These measures include increasing of thermal resistence (of the building case), the radiation shielding, the sun blinds and the passive cooling by the night ventilation. All the simulation are performed in TRNSYS 16.1 software.

Ventilation and heating in a single family house
Sláčík, Ondřej ; Lízal, František (referee) ; Charvát, Pavel (advisor)
This master’s thesis deals with the design of the ventilation and heating system in low-energy single family house. The thesis is divided into three parts. The first part of the thesis provides an overview of the project together with the requirements of the house owner. The options for heating and ventilation in low-energy buildings are also discussed in this part. The second part deals with the design of the ventilation system with heat recovery. The design includes determination of the amount of ventilation air, selection of a suitable ventilation unit and the design of the supply air and return air ductworks. The last part focuses on the heating system. It includes the calculations of the heat loss of the house and design of floor heating. Furthermore, the selection of heat source together with the safety measures is described in this part. Both design parts include the bills of materials, along with the budget and the drawings.

Heating and ventilation in the "Doubrava" family house
Jirsová, Tereza ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The diploma thesis is focused on the design of heating and forced ventilation for the project of the family house Doubrava. In the first two chapters is briefly described the theory and there is also described the project of the family house. The next chapter deals with the design of the forced equal pressure ventilation with the heat and moisture recovery. Than the heat loss are calculated according to the norm ČSN EN 12831-1. The next part is focused on the design of heating system and the heat source for the family house Doubrava. There is described detailed design of the floor heating, including necessary calculations, and also the type of the heat pump, as the heat source and source for hot water heating, is chosen. This part also contains a selection of expansion tank and safety valve and approximate calculation of the size of the primar circuit. The last part deals with the possibilities of using renewable energy sources. At the end of the thesis, there are more detailed results of the calculations and the mechanical drawings of individual designs of the ventilation and heating system and also there are tables of the acquisition costs.

A heating system in a retrofitted house
Valášek, Martin ; Bělka, Miloslav (referee) ; Charvát, Pavel (advisor)
The master’s thesis contains a complete design scheme of the heating system for a family house after additional thermal insulation of some structures. In the first part, we will learn about the house and the climatic conditions. In the next section there is the calculation of the overall heat transfer coefficients for building structures and also of the heat losses of the building before and after additional insulation. In the next section there is a selection of the temperature gradient, radiators, heat proposal for an option with a single source as well as for an option with two sources. The pressure losses through each element were calculated and hydraulic balancing using the thermo-regulation valves was performed. In the conclusion the safety components were checked and the total costs of both the implementation and the drawing documentation were assessed.
