Contribution on Buildings Design with Low Consumption of Energy Incorporated PCMs
The heating and cooling loads of buildings are most of the time due to heat transfer through building envelope. From the point of view of energy saving, the most effective way to reduce these loads is to carry out thermal insulation with building envelope, between others, by using phase change materials (PCM). The effectiveness of walls protection systems depends on several parameters such as orientation, size and their thermal operation, with respect to the climate. In this work, we studied the t hermal behavior of a wall containing PCM (CaCl2.6H2O) to carry out the thermal and economic energy comfort in the buildings at summer. The objective of this work is determination of optimal insulation concentration for various wall orientations under the climatic conditions of Ouargla city (at south of Algeria). The results indicate that it is possible to obtain an optimal concentration of 15% of CaCl2.6H2O for all wall orientations. Moreover, West and South orientations provide heat transfer loads at equal cooling which are most strongly compared with East and North orientations. The weakest cooling load is given by the wall exposed to the North and the payback period is for all wall orientations South/West, East and North are respectively: 10.51, 9.14 and 8.51 years.
