Experimental Study on Heat Transfer in a Reduced Temperature Incorporating PCM in Walls

To construct comfort ambient temperature in establishment and decrease the usage of air conditioning system in construction, the phase change materials be involved in the proficient character in manage the room temperature. And now a days consumption of vitality factor for functioning of air conditioning system is tolerably high. On the basic of phase change material is integrated in to cement and also there isdecrease ambient temperature. Experiment setup was made by two different bricks andPCM. They are Cement Hollow Bricks (CHB), Red Clay Bricks (RCB), Sodium thiosulphate (PCM1), and Temperature indicator, Bundle of Thermocouple. This two types of bricks is commonly used in building construction. Heat transfer coefficient for cement hollow brick and red clay brick are 0.726 W/ (m2 K) and 2.2 W/ (m2 K). Here the PCM is Sodium thiosulphate. It is in solid condition. The thermal conductivity of the PCM is 0.6035 W/ m K . I considered four wall with a height is 60 cm. The first wall is built by Red clay bricks without sodium thiosulphate and the second wall is RCB with sodium thiosulphate pcm. The third wall is made by CHB without sodium thiosulphate and fourth wall is built by CHB with sodium thiosulphate pcm. Key words : Red Clay Brick, Cement Hollow Brick, Sodium thiosulphate pentahydrate.,
