Abstract: 

In the present work a new cooling technique for buildings or car ceiling has been presented and investigated analytically. The new cooling technique uses several types of phase change materials (PCM) that is filling an enclosure that surrounds the wall buildings or car ceiling completely. It is found that the new phase-Change cooling technique is more appropriate for cooling especially in hot climate countries. This can save much of electrical power used for cooling process of buildings and autos and in turn solves many environmental problems. The new phase-Change cooling technique shows much better cooling performance when compared with the conventional sensible cooling one. Advantages can be also taken from the latent heat stored within the PCM in its liquid phase. This occurs when the PCM releases its latent heat of solidification. The new technique of using PCM can save much cooling energy that required for cooling the interior space of rooms or cars. The saving energy is about 78.6% from the initial energy required for cooling without PCM. It is found that the cooling operational time increases as both the melting temperature and the enthalpy of melting increase. Also, the PCM Paraffin (RT26) gives the optimum results for cooling.
