(EDP Sciences, 2015-05-06)The analyzed topic belongs to the field of design and operation of HVAC systems, focusing mainly on mixing chambers. The paper deals with problems of condensation and freezing of water vapour on walls of mixing chambers ... -
Hybrid Roof Panels for Night Cooling and Solar Energy Utilization in Buildings
(Elsevier, 2015-08-28)The aim of this contribution is to evaluate the usability of solar hybrid panels, which were originally optimized for heat load removal from buildings by radiation against the night sky, for water preheating. First we ... -
Optimalizace výpočtového modelu místnosti s chladicím trámcem pomocí experimentálního měření v reálných podmínkách
(IBPSA-CZ, ČVUT, 2008-11-06)Simulační řešení je v dnešní době jednou z nejaktuálnějších metod, pomocí které lze postihnout výměnu tepla, látky a dynamiku tekutin ve zkoumaném prostoru. Nejzásadnější předpoklad správného zpracovávání numerických CFD ... -
Theoretical evaluation of night sky cooling in the Czech Republic
(Elsevier, 2014-01-22)Energy necessary for cooling of building in summer season makes a big part of energy required for building operation. Redundant heat removal in summer can be realized in various ways. One of possible methods, mainly in ... -
Thermal Analysis of Light Pipes for Insulated Flat Roofs
(Elsevier B.V., 2014-10-22)Light pipes transmit daylight into building interiors. Their installation into thermally insulated roofs of low energy buildings can be a problem because of thermal bridges and condensation problems. This article is focused ...
