Abstract 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. Keywords Coolant • Phase change material • Reduce carbon emissions • Energy efficient

1 Introduction As demand for Air conditioning and Refrigerants are emphatically enhanced during last decennium, it should be economically abated in order to obtain comfort cooling in buildings. Zain [1] studied about the thermal comfort of a building in 2007. During scorching summer, peak demands of electric power is escalating year by year and limited reserves of fossil fuels have led to a surge of interest with efficient energy application. Usually, day time load has become double that of the night time load. This is due to usage of Air Conditioner both in day as well as in the night. Therefore our system would be the best way to eradicate the peak demand of using electricity during night as well as day time, thereby reducing air conditioner load. Salyer [2] indulged in the work of refrigeration and air conditioning in the residential buildings using unconventional energies and latent heat storage in 1990. This paper focuses on cooling of building by using slabs of Phase Change Material which is very attractive because of its high thermal storage capacity. In the past years, Abhat [3] confabulate the concept of latent heat storage materials in low temperature in 1983 itself. Cho
