In 21st century, the global warming has become great threat to mankind. The Air Conditioner became mandatory for room cooling in all the households which releases poisonous gases like CFCs and CO2 and also depends on electric power. The best promising alternative for less energy consumption is the passive cooling technique. Passive cooling (PC) is the process of reducing the temperature of a specified region without using electricity. In this paper, we discussed about the passive cooling of a room with the help of natural convection and solar chimney. The set up consists of a plastic pipe, copper pipe, solar chimney and a room. The solar chimney reduces the density of the air in the chimney, due to this density difference, the cool air enters the room and the air present in the room flows into the chimney. The atmospheric air is passed through the copper pipe which is placed underground near the water resource. So the heat available in the atmospheric air will be convected naturally through the walls of copper pipe to the water. In this experiment, we achieved about 1.5 to 2K of temperature reduction.
