  3. 17. Metoder för att motverka värmestress hos slaktgrisar

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Julia Ancher; [2021]
    Keywords : slaktsvin; kylning; temperatur; beteende;

    Abstract : Grisar är högproducerande djur som är känsliga för värmestress. Klimatförändringarna leder till ökade perioder av värme och det är därför viktigt att finna applicerbara metoder som erbjuder grisarna kyla. Värmestress påverkar grisarnas välfärd och leder till en rad olika förändringar i det naturliga beteendet. READ MORE

  4. 18. Frosting and Defrosting on Air Source Heat Pump Evaporators

    University essay from KTH/Energiteknik

    Author : Camilla Sandström; [2021]
    Keywords : ;

    Abstract : Air source heat pumps has become increasingly popular for residential households as they are considered an energy efficient alternative on the heating market. The air source heat pumps use the outdoor air as heat source and can operate in cold climates around -15 to -20°C, but as the temperatures drops below 6°C the heat pump experiences problems with frost accumulating on the heat exchanger.
