KOMPAS.com - The use of air conditioners is often not a solution to cool the room. Identify the cause of the heat of the room in your home.
Leisure time activities in space is not only dependent on the temperature of the room. Convenience is also related to the structural elements that "work" withstand exposure to light and heat so that the filter does not get into the room.
Can maintain a comfortable temperature by reducing heat transfer outdoors into buildings. Vice versa. As much as possible, we must be able to withstand cold temperatures move from inside to outside the building. This transfer can occur in 3 processes, namely convection (convection), conduction (conduction), and radiation (radiation).
According to Adi Bhakti, Project Sales Manager of PT. MDU Award, conduction can occur because there is heat transfer through berpenghantar objects. The easiest example is a cup of tea can be hot because hot water holds.
Convection is heat transfer due to air movement, the hot air rises up and the cold air will fall down. Wind can bring hot air into the house. While the radiation caused by the heat absorbed in the material or material that has the ability to increase the temperature of the object.
The easiest example is a car parked in the sun. Radiation heat will cause the contents of the car was also heat sealed car though.
Radiation heat accumulated in the car was the cause. In fact, it could be the temperature outside the car was not as hot as it was.
Of course, it can also occur in your building. To prevent this, you can use a coating that serves as thermal insulation from the three processes above.
Its use is not only for the roof, but also the walls. Because the walls are generally west-facing media can be conduction of heat radiation.
