(57) Abstract :
A cooling system for providing personalized comfort conditions by spot air conditioner system providing continuous flow of cooled
clean fresh air free of cross contamination. The system provides means for multiple vortex bolus generation and projection of cool air
bolus for personalized cooling as multiple boluses in time sequences reaching target individual without dissipating in the ambient air
instead of cooling an entire room and thus saving on energy consumption. The spot air conditioning is portable and can be easily
carried and installed for target specific cooling purposes. The system uses thermoelectric element operating at lower temperature
differential and close to maximum thermoelectric efficiency, whereby the high heat transfer rate at low temperature differential
potential of evaporative cooling is linked to the low heat transfer rate at high temperature differential property of thermoelectric
cooling. The system is suitable for domestic and industrial application in a simple and cost effective manner in hospital wards/cabins,
office/work centers, hotels, canteens or domestic settings meeting the personal comfort as well as environmental/hygienic
requirements.
