Abstract

The paper presents results of a study of heating habits (particularly the reported temperature in the living room during the heating season) in three EU regions: Aberdeenshire in Scotland, Brandenburg state in Germany, and South Bohemia in the Czech Republic. Data were collected using a questionnaire study carried out in 2010. There were approximately 500 respondents in each region. Three types of data are analysed: socio-demographics (including gender, age, education, income); housing characteristics (e.g. type, size, insulation, heating system), and attitudes towards energy and environmental issues (perception of climate change and perceived self-efficacy of energy saving). The results show some explanatory power of income, house insulation, age, place of living and self-efficacy on people’s reported living room temperatures. The biggest differences were found, however, between the three regions. Scottish households report the lowest average temperature, Germans higher and Czechs the highest. We also discuss the role of the local climatic conditions and put the results (especially the negligible role of most socio-demographics and housing characteristics) into the framework of theory of social practice and discussions about the limits of traditional sociopsychological ABC models (attitude-behaviour-choice) of pro-environmental behaviours.

Abstract

The paper presents a simplified mathematical model of linear induction motor to study its thermal regimes. The model takes into account the heat removal from the active zone due to the movement of the secondary element. The estimation of influence of motor speed on the temperature of its design elements is also verified.

Abstract

In my paper I´ve intended to collect theoretical knowledge of the issue of microclimatic conditions in the workplace and it´s impact on health and performance of the worker with the scope to workplaces ? cabins of train, city public transport and long distance transport drivers. I have proceeded from legally binding regulations. In the theoretical part I have described particular requirements and limits of factors affecting the quality of the inner workplace environment. After the theoretical part I have dealt with the practical part where I have proceeded from measurements which I have attended personally. I have completed my own measurements with the results of other measurement records elaborated by State Health Institute in Prague. Perspective measurements were interesting due to the ways technical devices were working and set to provide optimum microclimatic conditions in workplace. The largest measurement results were those from electric train units, known in our railway transport system as ?Pendolino?. While in the workplaces of engine drivers the set year-long inner environment limits have been mainly implemented, in the driver workplaces of public city and long distance transport, summer outside conditions had an impact on significant worsening of the microclimatic conditions ? a big temperature load on drivers, which is impossible to be eliminated without financially demanding measures.
