Efficient Cooling of Building Using Phase Change Materials Along with Coolant

Due to upsurge in the global warming day by day, ambient temperature escalates imperceptibly and hence the residence in the tropical region experiences severe hot climate which induces the need of Air Conditioning and Refrigerants. This paper focuses on theoretical analysis on cooling of building using Phase Change Material. In existing systems, the backup time for Phase Change Material gets over by the day, so in night time it can’t be used. This is the main shortcomings of this system. In order to overcome this, coolant is used to promulgate in aluminium bent shaped tube kept inside the slab of Phase Change Material in a well designed manner. In this paper, water is used as a coolant and is promulgated from the overhead water tank. In overall process, the room heat is carried away by the coolant from the overhead water tank. This leads to cool the Phase Change Material and in night time also it is possible to operate the system. The results of this paper show the time of cooling for a pondered volume of room and also its cost analysis. Factors like design, volume and selection of Phase Change Material etc., are carefully acclimatized to achieve effective forced convective heat transfer and efficacious cooling takes place. Finally this could become a great surrogate for Air conditioning.
