A book Building physics describes and explains physical phenomena and applications that are related to heat transfer and energy consumption in buildings, transfer of water and water wapor, building lighting, sound transmission and noise protection, establishment and spread of fires in buildings and thermal response of the urban environment. Adequate knowledge in field of building physics has become an essential tool in the design, planning and construction of buildings and their placement in the environment. Therefore, a building physics represents one of the basic skills not only to students of architecture, but also engineers. The content of the monograph Building physics is related to the memorandum prepared by the "group of building physics professors at European universities" which member is also author of this book. Book comprises 328 pages of A4 format.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 272851712Air conditioning of buildings became a need; especially cooling is becoming more and more important. On the basis of Slovenian regulation ten selected buildings and AC systems in Slovenia have been analyzed. Annual energy for heating and cooling has been determined. The contribution includes Energy Conservation Opportunities (ECO) for analyzed buildings. We have shown that savings of electrical energy even till 50 % can be reached.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 11324699The subject of the invention is a thermal mass flow meter comprising at least two thermal flow sensors with different constructional and/or operational parameters, and a gasidentification method. The thermal mass flow meter is used to measure the mass flow rate of different types of gases and to perform the gasidentification method. If the measurement characteristics for the proper gas are employed, the mass flow readings of the thermal flow sensors will be equal. In contrast, if the measurement characteristics for an improper gas are employed, the mass flow readings will differ. The thermal mass flow meter can be used together with control valve and control electronics to form a thermal mass flow controller.

COBISS.SI-ID: 13382683Growth of an isolated bubble and horizontal coalescence events between bubbles of dissimilar size were examined during pool nucleate boiling of water on a horizontal, electrically-heated titanium foil 25 lm thick. Wall temperature measurements on the back of the foil by high-speed IR camera, synchronized with high-speed video camera recordings of the bubble motion, improved the temporal and spatial resolution of previous observations by high-speed liquid crystal thermography to 1 ms and 40 lm, respectively, leading to better detailed maps of the transient distributions of wall heat flux. The observations revealed complex behaviour that disagreed with some other observations and current modelling assumptions for the mechanisms of heat transfer over the wall contact areas of bubbles and interactions between bubbles. Heat transfer occurred from the entire contact area and was not confined to a narrow peripheral triple-contact zone. There was evidence of an asymmetrical interaction between bubbles before coalescence. It was hypothesised that a fast-growing bubble pushed superheated liquid under a slow-growing bubble. Contact of this liquid with regions of the wall that had been pre-cooled during bubble growth caused local reductions in the wall heat flux. During coalescence, movement of liquid under both bubbles caused further changes in the wall heat flux that also depended on pre-cooling. Contraction of the contact area caused a peripheral reduction in the heat fluxand there was no evidence of a large increase in heat flux during detachment. Boiling on very thin foils imposes special conditions. Sensitivity to the thermal history of the wall must be taken into account when applying the observations and hypotheses to other conditions.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 12107291The present invention lies in the field of electrocaloric energy conversion. More 5 specifically, the present invention relates to improvements in systems and methods which employ electrocaloric materials as a source of temperature variation in electrocaloric refrigeration processes. Even more specifically, the present invention relates to the application of electrocaloric materials in combination with a working fluid communicating with a heat source and a heat sink in counter flow.
