The main disadvantage of having an Air conditioner in our homes is that its running as well as initial cost is very much high. So to overcome this problem there is a very simple mechanical mean that can be easily employed in rural areas. The main concept here is that heat exchanger is placed considerably below in earths surface. This is done by digging up earths surface and placing the coil several feets below ground. Any cooling agent like water can be made to run through the coil. This arrangement takes up the advantage that even if the earths surface is hot or cool the temperature below remains constant. Thus during summer season the water can be made to run through the coil using a pump. The heat gained by water from room can be dissipitated below in ground.

Note: A small model of this project would require considerable expense. Also might not function properly in urban areas.
Very interesting stuff to read. Keep posting.
