ABSTRACT
The current work is focused in a solar-assisted ejector cooling system for air conditioner, in order to replace conventional compressor based air-conditioner systems which consume much more energy (W. Pridasawa, 2008). The main point of study will be the ejector, with special attention on the nozzle through parametrical analysis of geometries and initial conditions, aided by numerical analysis and 3D simulation analysis based on previous literature (S. Varga et al. 2009, B.J. Huang et al, 1999) with the objective of corroborating this results previously obtained and also proposing new conditions and geometries (S.K. Chou, et al. 2001, W. Pridasawas, et al. 2006, Anselm, et al. 2008, B.J. Huang, et al. 2001). The numerical analysis and simulations are done with the software Ansys© CFX 12.1, using three-dimensional simulation (B.J. Huang, et al. 1999, M. Dennis, 2009). For working fluid, water has been chosen, because it’s “green” inexpensive and readily available for practical and experimental uses (M. Dennis, et al. ANZSES 07, John D. Anderson, 1982, Z. Hoffman, et al. 1999, Ansys CFX Solver Theory Guide, 2006).
