  1. 1. Condensation irrigation a combined system for desalination and irrigation

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jenny Lindblom; Luleå tekniska universitet.; [2012]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : Condensation Irrigation (CI) is a new irrigation method that combines desalination and subsurface irrigation by making use of saline water for supplying clean irrigation. In this system, solar stills are used for evaporating non-potable water, and the formed vapour heats and humidifies the ambient air above the water surface. LÄS MER

  2. 2. Condensation irrigation simulations of heat and mass transfer

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Jenny Lindblom; Luleå tekniska universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : There is a growing water demand in the world. Along with the deterioration of existing water supplies, the escalating world population leads to the assumption that two out of three people will lack sufficient freshwater by the year 2025. LÄS MER

  3. 3. Condensation and frost formation in fibrous thermal-insulation materials

    Detta är en avhandling från Stockholm : US-AB

    Författare :Tomáš Vrána; KTH.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibrous thermal insulation; Stone wool; Cellulose; MAterial properties; Moisture transport; Condensation; Frost formation; Exterior conditions; Interior conditions; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur; TECHNOLOGY Materials science Construction materials; TEKNIKVETENSKAP Teknisk materialvetenskap Konstruktionsmaterial;

    Sammanfattning : Heavily insulated constructions are at present being used to strike at the vast energy consumption in residential buildings and commercial alike. They introduce a high-thickness layer of thermal insulation in the building envelopes. LÄS MER

  4. 4. External Water Condensation and Angular Solar Absorptance Theoretical Analysis and Practical Experience of Modern Windows

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Anna Werner; Uppsala universitet.; [2007]
    Nyckelord :Engineering physics; Windows; External condensation; Radiative cooling; Optical properties; Coated glass; External condensation; Radiant cooling; Teknisk fysik;

    Sammanfattning : Part I of this thesis is a theoretical background to parts II and III.Part II treats the phenomenon of decreased visibility through a glazing due to external water condensation, dew, on the external surface. Some simulations are presented where it is shown that under certain circumstances condensation can be expected. LÄS MER

  5. 5. Invändig tilläggsisolering : köldbryggor, fukt, rörelser och beständighet : thermal bridges, moisture problems, movements and durability = Internal additional insulation

    Detta är en avhandling från Byggnadsfysik LTH, Lunds Tekniska Högskola

    Författare :Ann-Charlotte Andersson; [1979]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additional insulation; thermal bridges; thermal stresses; moisture; condensation; frost resistance.;

    Sammanfattning : The report deals with the problems which may be caused by internal additional insulation of an existing building component. Problems treated in this report are heat losses through and surface condensation at thermal bridges, condensation in the building components, stresses due to temperature and moisture content variations and possibly frost damage in facade materials.
