1. Properties of oil and refrigerant mixtures : lubrication of ball bearings in refrigeration compressors
Sammanfattning : A refrigeration compressor contains highly loaded mechanical contacts that have to be lubricated. The lubricant used in refrigeration compressors consists of an oil and refrigerant mixture, and the refrigerant concentration can be up to 40 wt%. LÄS MER
2. Determination and evaluation of pressure-volume-temperature relationships of some halogenated hydrocarbons and their binary mixtures : an experimental and theoretical study
Sammanfattning : .... LÄS MER
3. New refrigerants for vapour compression refrigeration and heat pump systems : evaluation in a context of the requirements set by the F-gas Regulation and the Paris Agreement goals
Sammanfattning : Given the global commitment to reduce the impact of fluorinated gases on climate and the regulations controlling their use in the European Union (EU), this thesis investigates new refrigerants that have been recently proposed to meet the demands of the refrigeration industry in the EU, which must satisfy the legislative requirements of the F-gas Regulation and facilitate meeting the goals of the Paris Agreement.The legislative requirements of the EU have intensified refrigerant development with reduced GWP.

4. Corresponding States Correlations for the Prediction of Thermodynamic Properties of Refrigerants
Sammanfattning : When process equipment such as separation units, heat pumps, and refrigeration systems are simulated or designed, physico-chemical properties of the fluids involved must be known. The outcome of the simulation or design depends on the accuracy of the correlations used in the prediction of physico-chemical data, so it is of the utmost importance that the correlations used correctly describe the properties of the fluids.
