Free Cooling with Phase Change Materials (PCM)
Phase change materials (PCM) are described along with some of their advantages in air conditioning installations, particularly with regard to taking advantage of the free cooling that can be obtained from the ambient air, by using either sensible heat or evaporation. Certain installations are described and the paper concludes by stating that PCMs in microcapsules will facilitate the use of free cooling.
