Working efficiency of boilers
Rejsa, Vojtěch ; Horák, Petr (referee) ; Počinková, Marcela (advisor)
This work deals with the determination of the operational efficiency of solid fules boilers for their inclusion in the relevant emission class according to ČSN EN 303-5. Two steel boilers of the same manufacturer, type and performance but of different ages, were measured. The experimental measurments in the real operation of the boilers were carrien out during the combustion of two types of fuels, namely brown coal and spruce wood.The operational efficiency of the monitored sources was calculated from the measured data using both direct and undirect methods. The found efficiency of the boilers corresponds to the expected values, due to their construction, age and the way of using individual components and regulations. In the project part of this work there is a proposal of heating of the family house for the condition of the building before and after the insulation. The calculation was made for the solid fuel boiler and heat pump. The building is heated by radiators and floor heating. The design of the whole system, technical report and project documentation were prepared for each variant.

Heating and preparation of the HDW via a heat pump
Rejsa, Vojtěch ; Blasinski, Petr (referee) ; Horák, Petr (advisor)
The bachelor thesis solves the design of heating in kindergarten in town Ostrava. The theoretical part deals with the topic of heat pumps. The calculating part conta-ins the design of heating the building using hot-water underfloor heating and the radiators. As heat source is designed heat pump air-water. Part of the calculation is also the preparation of hot water and design all the necessary equipment of the system.
