1. 1. Putsens inverkan på fasadens fuktbalans

   Författare :Kenneth Sandin; Avdelningen för Byggnadsmaterial; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rendering; moisture; driving rain; absorption; drying; provningsmetoder; mätmetoder; kondens; slagregn; fukt; ytterväggar; puts; fasader; pore structure; surface coating; diffusion;

   Sammanfattning : The report deals with the effect of renderings on the moisture balance in facades. The main therne is the moisture mechanism in cnnnection with different moisture sources. Different opinions about moisture in facades and consequences of moisture are mentioned as a background. LÄS MER

3. 2. Localised corrosion and atmospheric corrosion of stainless steels

   Författare :Sukanya Hägg Mameng; Rachel Pettersson; Christopher Leygraf; Thomas Ladwein; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; localised corrosion; atmospheric corrosion; alloy composition; surface finish; surface roughness; surface treatment; surface orientation; contamination; chloride; sulphate; temperature; chlorination; exposure conditions.; Kemi; Chemistry;

   Sammanfattning : This research is focused on defining limiting conditions for corrosion of stainless steels. The aim of the first part (Papers I-IV) was to understand the role of alloying level and environmental parameters on localised corrosion in aqueous conditions. LÄS MER

4. 3. Advances in Ventilation Heat Recovery : An assessment of peak loads shaving using renewables

   Författare :Behrouz Nourozi; Sasan Sadrizadeh; Adnan Ploskic; Carey Simonson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peak heat load shaving; renewable energy; ventilation heat recovery; frosting in heat exchangers; Heat transfer; förnybar energi; ventilation värmeåtervinning; frosting i värmeväxlare; värmeöverföring; Byggvetenskap; Civil and Architectural Engineering;

   Sammanfattning : The building sector accounts for approximately 40% of total global energy usage.In residential buildings located in cold climate countries, 30-60% of this energy isused for space heating, 20–30% is lost by discarded residential wastewater, and therest is devoted to ventilation heat loss.

5. 4. Laminar-flow Liquid-to-air Heat Exchangers - Energy-efficient Display Cabinet Applications

   Författare :Caroline Haglund Stignor; Värmeöverföring; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; indirect cooling; display cabinet; pressure drop; heat transfer; flat-tube heat exchanger; cooling coil; laminar;

   Sammanfattning : Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. LÄS MER

7. 5. Metoder att välja korrektioner vid fuktberäkningar med variabelt utomhusklimat

   Författare :Eva Harderup; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture flow; Moisture; numerical modelling; calculation model; moisture distribution; non-linear moisture flow; external climate; moisture calculations; corrections; Building construction; periodic boundary condition; reference year; Byggnadsteknik;

   Sammanfattning : Determination of the design conditions for moisture resistance requires in a Moisture Design number of different moisture calculations to be made in order to determine the moisture status within, or on the surface of, a structure. The objective of this work has been to ascertain how to allow for variations in climate data in order to be able to determine the most unfavourable moisture status likely to be encountered during the life of a building.
