Energy and environment are the two major issues facing human beings nowadays. Industrial developments and population boom in the past few centuries have resulted in an enormous increase in energy demand with an annual increasing rate at about 2.3%. Fig. 1 a and b, respectively, show the energy production from the year 1949 to

PCMs simultaneously change the phase from solid to liquid (energy absorbing) and liquid to solid (energy releasing). Therefore, a PCM should be thermally stable even after few cycles of operation. However, some researchers [23], [96], [113], [211] reported that most of the PCMs are thermally not stable after few cycles of operation.
Or with solar collectors [6], [7], [8], this technology is beneficial because it prevents the loss of heat and energy in pipes or duct networks, and also in terms of cost as storage tanks and
Paraffin wax consists of a mixture of mostly straight chain n -alkanes CH3– (CH2)–CH3. Both the melting point and latent heat of fusion increase with chain length. Paraffin qualifies as heat of fusion storage materials, due to their availability in a large temperature range.
At the temperature of 323 K, the adsorption heat of the activated carbon can be up to 762.47 kJ/kg, which is much higher than the latent heat of phase change of traditional phase change materials

The time it takes for each wax to complete 1 cycle, namely palm wax is 150 s, paraffin wax is 80 s, and soy wax is 276 s. So that within 1 hour of testing the thermal cycle of each sample, namely 24 cycles for palm wax, 80 cycles for paraffin wax and 13 cycles for soy wax.
The energy storage density and hence cost of storage system can be reduced by using a PCM with high latent heat and low cost. Thus, the development of novel PCM in the melting temperature of 21 °C with high latent heat, lower supercooling corrosion-free and easily biodegrade is necessary for the building cooling applications.
The paraffin wax is mainly mixed by the straight-chain paraffin,with long-term stability performance of physical and chemistry characters has many merits,such as can melt repeatedly,no subcooling or crystalline humor separation phenomenon during crystalline,cheap price,non-toxic,non-corrosiveness and so on.At the same time,the wax
