Analysis of HVAC systems of a low-energy house
Urban, Erik ; Bahr,, Josef (referee) ; Šikula, Ondřej (advisor)
In the first part, the diploma thesis addresses the issue of comparing individual HVAC systems for family houses. The second part is an experimental measurement of HVAC systems of a low-energy family house. The third part deals with the current state of heating and air conditioning of the family house, together with a certificate of energy performance of buildings. The diploma thesis is more focused on the experimental part.

Design of warm air heating system for low-energy house
Koutník, Martin ; Krejčí, Vladimír (referee) ; Košner, Jan (advisor)
The diploma thesis deals with design of warm air heating and ventilating system for low energy house. Introduction of this thesis is focused on dividing residential buildings by their heat requirement. Then problems of residential building ventilation and possibilities of warm air heating systems including heat recovery are presented. In the next chapter summary of ventilating units with heat recovery and warm air heating units for residential low energy buildings and pasive family houses is presented. Calculation of low energy house heat losses, which is solved, is based on CSN 06 0210, CSN 73 0540 and CSN EN 12831 standards. Design and calculation of warm air heating and ventilation system and ground heat exchangers is also described. Floor heating system, fireplace insert and solar heating system are designed as supplementary systems. At the end of this thesis the control system is presented. Project documentation is enclosed in appendix.

Design of a family house ventilation system
Hrbata, Jiří ; Zerzaňová, Alena (referee) ; Fišer, Jan (advisor)
Diploma thesis deals with design of the ventilation system for low-energy house. Introduction of the thesis is focused on ventilation needs and also includes a summary of main principals of ventilation systems which are commonly used in family houses. One chapter is dedicated to utilization of ground heat exchangers and also includes a CFD simulation. The actual design of the ventilation system for low-energy house assess the suitability of using local/central ventilation units and also determines the best method of controlling the system.

Ground Heat Exchangers - Operating States and their Influence on Microbiological Hazards
Kolbábek, Antonín ; Klánová, Kateřina (referee) ; Kratochvíl, Zdeněk (referee) ; Jaroš, Michal (advisor)
This thesis deals with the Air to Ground Heat Exchangers (AGHEx) and their effects on the hygienic quality of the supplied air and the microbial microclimate in the interior of buildings. The theoretical part focuses on current findings and knowledge in the field of warm air heating, ventilation of the low-energy and energy passive houses and ground heat exchanger for the ventilation systems to family houses. The next chapter deals with the quality of the indoor environment and the influence on HVAC systems on the building microclimate. The experimental part of the thesis presents the results of energy simulations of operation of air to ground heat exchanger, obtained using the simplified model, and the data from long-term monitoring of experimental AGHEx built at FME BUT. Furthermore, the results of microbiological research of several already operating air to ground heat exchangers are evaluated. The research was carried out using two different sampling methods: the method using swabs taken from the pipe wall, and the sedimentation (gravimetric) method. The conclusion part mentions the practical experiences of users and knowledge of the author relating to the design, operation and use of air to ground heat exchangers.

Energy simulation of ground heat exchanger influence to operation of warm-air heating recuperation unit
Kolbábek, Antonín ; Pešek, Martin (referee) ; Jaroš, Michal (advisor)
The thesis deals with energy simulation of a heat recovery system in coupling with a ground heat exchanger (GHE) in a low-energy family house with warm-air heating and ventilation. The effect of GHE on operation and effectiveness of a heat recovery unit was assessed from the results of the simulation. Next, energy and economic benefits of the heat recovery with and without GHE and consequent savings were evaluated as well. The profitability of the investment was assessed using comparison with the investment costs. Recommendations for the operation of the system were suggested.
