(57) Abstract :
It is commonly observed that cars, trucks, buses and other four wheel drives have air blower, air duct and louvers on the
dashboard for supply of fresh air in the vehicle cabin space. This provides some level of comfort for the driver and passengers. If
this unit is coupled with a vapor compression unit, then the whole system functions as automotive air-conditioner. However a
normal air-conditioner consumes energy and reduces mileage by 20%. This invention is about providing cool air in the cabin
space at almost negligible cost without the conventional air-conditioning system. The pressurized water is sprayed through a
nozzle into the air duct just before the louvers. The fresh air blown by the blower goes through the duct and finally through
louvers in the dashboard to the cabin space. If water is sprayed as fine droplets into the air stream, it gets cooled due to
evaporative cooling and cools the cabin space.
