Thermal Comfort: Advanced Management of Heating and Cooling in Buildings

02.11.2018

CTU UCEEB experts presented the results of their case study related to the perception of temperature conditions inside a building. The study shows what heating system is the most comfortable one for users. The data acquired will serve for the development of a temperature regulation system in a house. Its benefit will lie in the decrease of energy consumption and in the increase of quality of the indoor environment without significant financial costs.

The perception of certain thermal environment by people is influenced by a number of factors including their activities in the room, clothing, age, gender and mental condition. The aim of the project was to design and verify the function of so-called virtual temperature of air which captures well the properties of the heating or cooling surface, the habits of people and the parameters of the surrounding environment—indoors as well as outdoors. Another benefit should lie in the improvement of management of heating and cooling surfaces or the improvement of thermal comfort in the room based on a change of the surrounding environment or a change of user demands.

CTU UCEEB experts used four different heating systems for the research of thermal comfort in a room: convector, ceramic panel, floor heating, and ceiling foil. Their temperature ranged from 20 to 24 degrees. The research included the presence of several tested persons which were asked by the researches about the thermal environment that was the most comfortable for them.

The project, besides the testing and data analysis, includes the development of a system for controlling the temperature in the house, too.  According to the data acquired, the controller should be customized for the thermal comfort of the person in the room as much as possible. Unlike common temperature controllers that are available on the market, the developed system will take into account not only the temperature of the outdoor environment but also the activity of the person in the building, his/her choice of clothing and even the amount of money he/she is willing to spend on the heating of the house. This project will run until the end of August 2019.
