Control systems for family houses[edit]

Author: Marek Vachule

Diplomové práce 2011

The main goal of this diploma thesis was to describe main requirements for the heating of family houses. Based on the measurement of specific house optimal algorithms for central heating control were designed. In the introductory theoretical part of the work, the term family house is defined. Afterwards, a specific house and its concrete parameters are described.In the following part of the work possible internal and external influences on heating of family houses are discussed. In addition, a complete description of the development and details of the used software and hardware is provided. The principles of data storage and the structure of the measurement are described as well. In the subsequent part, the acquired data from both temperature and gas consumption measurements are analysed and described. In the end, several comparison graphs for internal and external temperatures are presented. As part of the analysis the house heat penetration is calculated. In conclusion part of the work, the heat-balance model of family house simulated in Simulink toolbox IBPT (DTU) is presented. This model is based on experimental data from the measured house. The results are presented in the final part of the work. Work so far indicates that the heating of houses is very complicated sum of many influences. It was found that the quality design of piping, number of heating elements and their size, the residents can control the temperature in the house alone single radiator valves. Thermostats then have meaning only in rooms prone to rapid heating of the sun. So it's mostly a room facing south and located just under the roof of the house when the roof substantially transmits heat or the storage capacity. A major benefit of the work itself is stimulating the creation of a comprehensive measurement system including hardware.
