Den raka vägen för både luft och information : En studie av den interna kommunikationen på ett svenskt företag i ventilationsbranschenKjellin, Sandra January 2012 (has links)
Undersökningen syftar till att beskriva den teoretiska och den praktiska interna kommunikationen på Systemair AB, med fokus på kommunikationsprocessen vid nylanseringar, upphittade fel i dokumentation samt reklamationer. Frågeställningarna jag använt är: Hur ser kommunikationsflödet ut teoretiskt? Hur fungerar det i praktikenFör att få fram ett resultat har jag dels studerat företagets skriftliga rutiner, och dels använt mig av en kvalitativ metod i form av personliga intervjuer. Jag har intervjuat totalt 12 anställda på 6 olika avdelningar som på ett eller annat sätt berörs i en eller flera av de utvalda processerna. Så småningom skickades även några uppföljande frågor till samtliga informanter per e-post, där de hade möjlighet att komplettera sina synpunkter kring de processer de berördes av.Utifrån det sammanställda resultatet kan jag dra slutsatsen att Systemair AB har framtagna rutiner och arbetsprocesser för samtliga tre utvalda fall, men att det framför allt vid lansering av nya produkter behöver ses över hur det fungerar i praktiken samt vilka avdelningar som berörs. Något som fungerar bra är hanteringen vid reklamationer där rutinerna är tydliga och systemet som används för registrering är lätt att använda. Till sist kan jag dra slutsatsen att de problem som finns med rutinerna vid till exempel nylansering kan vara relativt lätta att åtgärda vilket skulle underlätta arbetet väsentligt.

Assessment of Energy Recovery Technology in China : Mechanical ventilation system with energy recoveryPiippo, Kaj January 2008 (has links)
<p><!-- --></p><p>In the wake of the economic growth of the Chinese market the past couple of decades, the energy consumption has surged. One of the biggest consequences of the increased energy consumption is a massive increase in CO<sub>2</sub> emission. In fact, China has overtaken the U.S. as the biggest emitter of CO<sub>2</sub>. In light of this energy-saving technology gets more important to implement. District heating is one of the solutions used with success in parts of China where heating is required. In this paper, an energy recovery technology has been examined for two climate zones in China namely a mechanical ventilation system using a flat-plate counter-flow heat exchanger. Beijing is located in a cold zone while Hong Kong is located in a zone with hot summers and mild winters. Cooling load calculations were conducted manually using the RTS - method developed by ASHRAE and heating load calculations were conducted for Beijing using Swedish guidelines stated in BBR. Further, the energy recovery unit (VM1) that was provided by Systemair AB was tested using a rig where different outdoor conditions were simulated. This data was then used to evaluate the potential for energy recovery in a model apartment located in the two zones. As expected, significant differences were obtained when comparing the performance for the two locations.</p><p> </p> / Redan avklarad
