The analysis of the possibilities to control temperature in a building using the TELETASK system automation

The paper presents the distribution of costs of functioning of a building over a period of several decades of its use. Above all, devices and systems which consume electricity and thermal energy were taken into account. The necessity to select an appropriate method of temperature control in order to achieve measurable economic benefits and the impact of these benefits on the life and work of the building users were clarified. The methods and modes of temperature control in rooms based on real installation made using the Teletask intelligent building system were described. The design of the temperature control system for living and office spaces was prepared. The measurements, using the Teletask system components were carried out in order to indicate the time during which the heating system was to be switched on and off, while ensuring the set temperature in the room. An estimation was made with regards to the possible savings owing to the installation of the building intelligent system for temperature control in rooms intended for various purposes.

Heat flow in installations with photovoltaic tiles

The paper presents methods for determining similarity numbers do define the density of heat flux in a system. An installation was analysed with photovoltaic tiles located on the roof of a building. The values of similarity numbers and heat flux were determined, and the type of the system was defined for the case analysed.
