ABSTRACT
This report is concentrating on the natural cooling system for a cabin, which will not
require much power consumption (electricity). 1t is about how the project of an
underground cooling system is continued by designing a cabin and it is built on the
complete underground cooling system. Few things is considered before the real natural
cooling system develops. The base is built on the site and it has 4 holes for pipes to extend them to the top of the cabin. But, before the pipe extension, walls are built with a
specific design to avoid the heat transfer, either from inside the cabin and out-off it, or
vice-versa. Walls are built with 3 layers of material; 2 layers of planks and 1 layer of
foam. These walls are built using the concept of sandwich. The piece of foam is put
between the two pieces of planks. Then, the extended pipes are connected to the
wooden-box and diffuser which are located on the roof. The diffuser spreads the cool air
from the underground to the whole volume of the cabin. For it to work well, the exhaust
fan is put in the wooden-box before the diffuser and the sensor is put to sense the
temperature changes. The exhaust fan will only work when the sensor detects the
specific comfortable temperature that is to be set for the natural cooling system. The
diffuser then spread the cool air and the cabin temperatures are measured before and while the cooling system is working for specific times. If the project is successful, the
comfortable temperature of cabin will be achieved.
