Introduction to Coupled Vane compressor: Mathematical modelling with validation.

Author(s) : SHAKYA P., OOI K. T.

Type of article: IJR article


A new rotary compressor known as Coupled Vane compressor (CVC) is introduced. The unique feature of CVC is that a set of two vanes are coupled together and they cut through the rotor diametrically. Theoretically, any rotor size which can accommodate the vanes will work with this design. This design removes most of the geometrical constraints imposed on the size of the rotor, as what are in most of the rotary compressors. The ability to accommodate a significantly small rotor in this new design, makes it substantially more compact which, also reduces material wastage, cost of machining and fabrication. This new design is intended to be used in refrigeration, household cooling and heating applications. In this paper, the mathematical models of the CVC were formulated to study its operational characteristics. The results of the simulation model were validated using measured data from a CVC prototype. This CVC prototype, with a volumetric displacement of 44 cm3, was operated in an open-type configuration using air as the working fluid. The predicted results were generally found to be within 15% of the measured data.
