For temperature of 20.68
◦ C((H ) = 16.7698 J/g
Heat absorbed for this range (28.01–20.68) (H) = (75.8737 – 16.7698) J/g =
59.1039 J/g.
Weight of the PCM non-woven material used in the experiments (m) = 66 g.
Hence heat absorbed = 59.1039 × 66{(J/g) × g} = 3900.8574 J
Heat absorbed in Watts = 3900.8574/219.9 J/s = 17.74 W
Similarly, the calculations can be done for the other PCM materials (i.e. foam,
fabric and composite) as explained above.
