  1. 1. Clothing Evaporative Resistance: Its Measurements and Application in Prediction of Heat Strain

    Författare :Faming Wang; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal manikin; clothing ensemble; evaporative resistance; localised evaporative resistance; thermophysiological response; heat stress; heat strain; the Predicted Heat Strain PHS model;

    Sammanfattning : Clothing evaporative resistance is one of the most important inputs for both the modelling and for standards dealing with thermal comfort and heat stress. It might be determined on guarded hotplates, on sweating manikins or even on human subjects. LÄS MER

  2. 2. Evaporative Cycles - in Theori and in Practise

    Författare :Per M Rosén; Kraftverksteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; Trigeneration; Combustion Engines; Gas Turbines; CHAT; HAM; HAT; Evaporative Cycles; EvGT; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : The thesis is based on applied research, rather closed to industrial development. The developed simulation model, for pre-design of evaporative gas turbine cycles, has been validated in a 600 kW pilot plant and in rebuilt turbo-charged diesel engines. LÄS MER

  3. 3. Humidification in Evaporative Power Cycles

    Författare :Farnosh Dalili; KTH; []
    Nyckelord :Gas Turbines; EvGT; HAT; Humidification; Evaporator; Saturator;

    Sammanfattning : Evaporative gas turbine cycles (EvGT) show an exceptionalexhaust heat recovery potential, which makes them a strongcompetitor to other advanced gas turbine cycles, especiallyfrom small to intermediate sizes. Evaporative gas turbines aredistinguished by humidifying the working fluid beforecombustion at temperatures below the boiling point of water;and the heat required for evaporation of water is partly takenout of the exhaust gas.

  4. 4. Developing Humidified Gas Turbine Cycles

    Författare :Michael Bartlett; KTH; []
    Nyckelord :advanced gas turbine cycles; evaporative; humidified; power; heat and power;

    Sammanfattning : As a result of their unique heat recovery properties,Humidified Gas Turbine (HGT) cycles have the potential todeliver resource-effective energy to society. The EvaporativeGas Turbine (EvGT) Consortium in Sweden has been studying thesetypes of cycles for nearly a decade, but now stands at acrossroads, with commercial demonstration remaining. LÄS MER

  5. 5. Evaporative and Desiccant Cooling Techniques Feasibility When Applied to Air Conditioning

    Författare :Torbjörn Lindholm; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; desiccant wheel; desiccant cooling; evaporative cooling; dehumidification; air-conditioning; HVAC; comfort;

    Sammanfattning : This thesis describes evaporative and desiccant cooling processes for air-conditioning purposes, i.e. for the removal of surplus heat from premises by the supply of cooled ventilation air. These cooling processes can replace the conventional method of cooling ventilation air involving the use of refrigerating machinery. LÄS MER
