Effect of Rockwool Insulation on Room Temperature Distribution

Abstract

The excessive energy consumption through the last decades especially in air conditioning due to the negative awareness behaviour of consumers has reflected not only on the economy but also on the weather and environment. The aim of this study is to find the optimum thickness of Rockwool insulation to reduce the cooling load inside the buildings. Two items have been used through this research, VELOCICALC to measure the air temperature, humidity, and air velocity, with Infrared Thermometer to measure profile temperature of the walls. Three different thicknesses have been selected for the Rockwool insulation which are one layer 50 mm, two layers 100 mm and three layers 150 mm, as well as without insulation. The data present the 100 mm thickness layer of Rockwool is a better insulation thickness to reduce the heating load inside the room, the differential between outside and inside is 0.9°C, the Rockwool of one layer reduced only 0.5°C and the maximum thickness with three layers reduced only 1°C, which is not much effective compared to the two layers but even more costly. The results observed that the optimum thickness insulation is between 50 mm and   100 mm to reduce the temperature inside the room without wasting any cost for over insulating.
