2. 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
Abstract : 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.

3. Flow Boiling Heat Transfer and Pressure Drop. Experiments and Model Development for Complex Geometries
Abstract : Two very different evaporator geometries, a dimple plate and a herringbone microfin tube, have been studied. Heat transfer and pressure drop for both pure refrigerants and refrigerant mixtures have been determined experimentally. READ MORE

4. Measurements and Modelling of Convective Vaporization for Refrigerants in a Horizontal Tube
Abstract : An evaporator facility has been constructed to measure local values of heat transfer and pressure drop. The evaporator resembles a normal working evaporator tube in a direct-expansion evaporator applicable to large heat pump/refrigeration cycles, typically over 500 kW. The evaporator is brine-heated and uses an expansion valve to control the inlet. READ MORE
