Abstract

The use of a phase-change material (PCM) in a district cooling system was studied in order to increase the heat transfer performance of the system. One of the major technical obstacles to its use is the clogging of the piping system. The present study attemps to minimize the clogging problem by using an emulsifier. Effects of the emulsifier on the mixture of water and hexadecane (a PCM) were studied. A small amount (60 to 2,775 ppm) of emulsifier caused remarkable effects resulting in the production of fine PCM particles. As the amount of the emulsifier was increased in the 25% hexadecane mixture with water, the size of the solid particles of hexadecane became smaller. When the size of the hexadecane particles was small enough, they did not stick together or stick to the surface of the cold wall of a heat exchanger.
