2. The Compression/Absorption Heat Pump Cycle - System Simulations
Abstract : From the results presented in this thesis it is clear that the compression/absorption heat pump cycle offers several advantages over other types of heat pumps. In many cases it gives a higher or equally high COP compared with the single-fluid compression heat pump but also the smaller SCD (i.e. READ MORE

3. Properties of oil and refrigerant mixtures : lubrication of ball bearings in refrigeration compressors
Abstract : 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%. READ MORE

4. Corresponding States Correlations for the Prediction of Thermodynamic Properties of Refrigerants
Abstract : 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.

5. Bearing lubrication of refrigeration screw compressors
Abstract : The bearings in a modern refrigeration screw compressor are lubricated with a mixture of oil and refrigerant. However, little or no published bearing life data is available for the new generation non-chlorinated refrigerants. READ MORE
