Design and Friction Analysis of the Revolving Vane Compressor
Over the years, rotary compressors have gained significant popularity and widespread usage because of their compact nature and good vibration characteristics. Although possessing many advantages over the reciprocating compressors, one of the performance limitations of the rotary machines is their inferior mechanical efficiency due to the existence of large frictional losses, which occurs as a r...
متن کاملDesign Improvements of Revolving Vane Compressors, RV-i
A newly invented compressor, namely revolving vane compressor (RV) has been introduced two years ago (Teh and Ooi, 2006, 2006, 2006). This paper presents the improved version (Teh and Ooi, 2007) of the RV, called RV-i, where “i” stands for improved. The RV or RV-i is designed with the intention to overcome most of the limitations facing the working characteristics of the rolling piston compress...
متن کاملModelling and Simulation of the Dynamics of Cross Vane Expander-Compressor Unit for Vapour Compression Cycle
The Cross Vane mechanism was recently invented and employed in the design and development of an expandercompressor unit, named Cross Vane expander-compressor or CVEC in short. This device replaces the compressor and expansion valve of a conventional vapour compression cycle, and improves the energy efficiency of the system. Theoretical models which include geometrical, thermodynamics, mass flow...
متن کاملIntroduction of the Novel Cross Vane Expander-Compressor Unit for Vapour Compression Cycle
A new type of expander-compressor system called Cross Vane expander-compressor (CVEC) was introduced. This device replaces the expansion valve and compressor in conventional refrigeration systems to reduce the energy consumption and improve the coefficient of performance (COP) of the system. As opposed to many expander-compressor systems in the literature, whereby a separated expander is couple...
متن کاملModeling and Experimental Investigation on the Internal Leakage in a CO2 Rotary Vane Expander
A rotary vane expander has been developed to replace the throttling valve for improving the COP of transcritical CO2 refrigeration system. Due to the serious internal leakage, the expander efficiency is not satisfactory. This paper presents the theoretical and experimental investigation on the internal leakage in a rotary vane expander prototype. Firstly, the leakage flow rate through the inter...
