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 کاملCompressor with Turning-Paired Vane and Piston
With the aim of developing a method for reducing energy consumption of room air conditioners, we address a higher-efficiency design of the rotary compressor currently most used worldwide. We focused on a new rotary compressor equipped with a mechanism to restrict the rolling motion of the piston, and performed a dynamics analysis. The new rotary compressor has a small pillar at the tip of the v...
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 کاملVane Dynamics Analysis of a Tilted Vane Rotary Compressor
An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...
