2006. Studies on the micro vapor compressor for the application to a miniature refrigeration system. PhD thesis, School of Mechanical and Aerospace Engineering, Seoul National University, South Korea. Sliding vane rotary compressor technology and energy saving R Cipollone University of L’Aquila, Department of Industrial and Information Engineering and Economy, Italy ABSTRACT Energy saving, CO2 reduction and energy generation from renewable sources represent the three cornerstones of the energetic and environmental commitments of all the Countries in the World.

The blade inclination, in fact, changes the reaction forces and, consequently, the power dissipated by friction and the pressure distribution on the oil layer which avoids dry contact. Main processes concerning the behavior of a SVRC are: a) b) c) d) e) Filling and emptying of the vanes; Thermodynamic transformations inside the cells, considering oil injection and interactions (air cooling, oil drops motion and thermal effects. etc…); Motion of the blades inside the slots and reaction forces at the contact points; Pressure stabilization inside the oil film at the tip blade-stator contact; Oil separation from compressed air.
