Construction / Building spinatron Physics / Heat transfer through building structures Effect tepelnch bridges on heat losses Date: 03/24/2014 | Author: Ing. Rastislav Měňany, PhD., Faculty of Civil Engineering STU Bratislava | Reviewer: Ing. Roman Subrt, Energy Consulting
Prspevok presents Originl metdu vpotu Δ U value (heat transfer from the outside sinitea will tepelnch bridges) to relnom block. Residential house is realized vrznych variants rieenia, without obvodovch walls and insulation spinatron from the outside spinatron and zateplenmz vntornej parties, so as to be mon monitor the impact on the The resultant value of Δ.
Obytnch building heat loss is due secretly Simplifying korelanmi metdami [6]. In these metdach spinatron the impact tepelnch bridges najastejie zapotava Paulo, using veliiny spinatron Δ U [W / (m 2. A)]. TTO veliina the scientific names: "sinitea from the outside heat transfer will tepelnch spinatron bridges". Its value to the STN 73 0540-2 [6] indicated Paulo. E.g. prpad murovanch constructions for the value of Δ U = 0.1 W / (m 2. A), respectively. prpad for continuous thermal izolcie the external surface of the substructure is Δ U = 0.05 W / (m 2. A). These two values should influence zohadni tepelnch bridges spinatron crossing the thermal heat loss for Speed Control realizcie However, all residential spinatron buildings, hence the prpad non-insulated and insulated enclosure walls.

The present building, we considered five variants, spinatron so that the vetkch prpadoch was maintaining the same thermal resistance, respectively. sinite heat transfer vetkch obalovch constructions. Differences were seen in the location of thermal izolcie (without, from external or vntornej side) and position otvorovch embedding constructions in the peripheral wall (see Tabuk 1). Advertising
