The use of air conditioners, popularly known as AC, has become almost compulsory in number of homes and houses. In fact there are number of people who just can’t live without AC, they will need AC in their room, office, car, theater and almost everywhere. Why is it that we need AC?
Broadly it is very easy to understand that we need AC because the surrounding temperature is very high. True, that’s one of the major reasons that we feel hot and our body needs to cool down. Apart from surrounding heat there are a number of other sources that release heat inside the room that lead to the rise in temperature of the room that causes uncomfortable conditions. Let us see some of the sources of heat generated inside the room.
1) Heat from the sun: Sun is the major cause of generation of heat during the summer seasons and it is also the major source of heat generation inside the room. The rays of the sun enters the room via windows, walls and roof of the room, partitions etc. This is the major cause of heat production inside the room. This heat increases the temperature inside the room and we feel uncomfortable.
The total amount of heat generated inside the room due to sun depends largely on the direction or alignment of the room with respect to the sun. In the morning maximum amount of heat is absorbed from the walls and windows in the east direction. During noon the maximum amount of heat is absorbed by the walls and windows in the south direction and in late noon the maximum heat comes inside the room from walls and windows in the western direction.
The walls also tend to store the heat for long intervals of time. The heat absorbed by the walls throughout the day tends to get released inside the room at night thus, adding the heat to the room even at night.
