1. Performance comparison between reciprocating and scroll compressor heat pumps with R600a refrigerant
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A performance comparison of heat pumps using a scroll (Sanden) and a reciprocating (Bitzer) compressor was conducted experimentally. The refrigerant used was R600a (isobutane). LÄS MER
2. Evaluation of an economizersolution for a heat pump
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis evaluates the performance of a heat pump intended to be used as an economizer. The idea is to use the heat from still hot refrigerant after the condenser in a larger heat pump, running on propane, as the heat source for the economizer pump. LÄS MER
3. Analysis of short chain fatty acids in faecal samples : development and validation of a new method
Kandidat-uppsats, SLU/Dept. of Food ScienceSammanfattning : Short chain fatty acids (SCFA) are produced by the gut microflora following the intake of complex carbohydrates and have been suggested as a contributor for some of the health benefits associated with dietary fibre (DF) intake. For further research of the mechanisms and effects of SCFA, reliable and accurate methods for analysis of SCFA in different biological samples are needed. LÄS MER
