Abstract [sv]

Jordens klimat är idag tunga frågor, det handlar om allt från polarisen som smälter på grund av den stigande temperaturen till sinande oljeresurser i världen. Arbetets mål är att minska energianvändningen, uppskatta vad ett sådant system skulle kosta och vad blir miljövinsten? Med hjälp av en energikartläggning identifieras energiflödena samt ett koncept tas fram för värmeåtervinning med värmeåtervinningsbatteri och värmepump. En kostnadsbedömning och resultatkalkyl görs med konceptet som grund. Resultatet blir ett system som kostar runt 5,3mnkr med en payoff-tid på ca 4 år. Arbetet minskar \(CO_2\)-utsläppen med ca 747ton vilket motsvarar 738 resor med flyg från Stockholm till New York tur och retur.

Abstract [en]

Today's climate change is a big issue, it covers everything from the polar ice melting due to rising temperatures to dwindling oil resources in the world. This paper aims to reduce the energy use, estimate what such a system would cost and what will be the environmental benefit? With the help of an energy audit identifies energy flows as well as a heat scource and a heat sink. A concept was made with the run-around for a heat pump and heat exchanger. A cost assessment and profit and loss statement is done with the concept as a basis. The result is a system that cost around 5.3 million with a payoff period of about 4 years. Work decreases \(CO_2 \) emissions by about 747ton which is equivalent to 738 Flight from Stockholm to New York and back.
