… att hitta svagheter som behövde åtgärdas. De två vanligaste befuktartyperna är Heated Humidifier och Heat and Moisture Exchanger. Den främsta nackdelen med Heated Humidifier var dess tendens att övermätta luften med kondensutfällning som följd, och med Heat and Moisture Exhanger …
… was set on the modelling of warm engine, but also the more complex engine heat-up phase was investigated since it is a great contributor to total emissions. While NO xcould not be measured because of malfunctioning measurement equipment, only HC, CO and temperature at inlet of …
… The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study of different …
Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of …

Beräkningar intervjuer och analys av energikraven i Boverkets Byggregler
… The energy balance of these houses is studied specifically when an exhaust air heat pump or a ventilation heat exchanger is used in order to save energy. To make this work particularly interesting, the window area was changed to see how this would affect the energy use in the …
The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The …

… studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the …
