Abstract [sv]

Värmepumpar ger ifrån sig ljud när dessa kommer upp i temperatur, vilket kan bli ett problem då det kan störa omgivningen. Om man kan sänka ljudnivån blir den mer attraktiv för kunderna.Syftet med examensarbetet är att undersöka om det går att mäta ljudet och vibrationerna som uppstår när komprimerad gas expanderar snabbt i samband med att den lämnar kompressorn.En dämpare som minimerar oljudet samtidigt som den är billig, kostnadseffektiv samt enkelska sedan konstrueras. Dämparna som testades varierade i storlek och form. En av de testade dämpare gav till sist en vibrationsdämpning av värmepumpen och tillverkades sedan.

Abstract [en]

The heat pump emits noise when the temperature increases, which can be a disturbing factor to the surrounding environment. The heat pump could become more attractive to the costumers if the noise was decreased.The objective with the examination paper is to investigate if the noise and vibrations could be measured that occurs when a compressed gas expands and leaves the compressor rapidly. A cheap, costeffective and simple damper will be constructed.The dampers that were tested had a diversity of shapes and forms, and at last the damper with damping materials gave a decreased vibration.
