Several disadvantages of PCM use in the given application have been identified and include; super cooling, low thermal conductivity, phase segregation, fire safety, and cost. The issues caused by super cooling and phase segregation lead to thermal cycling degradation, limiting the useful lifecycle of...
These results show that PCM waste heat recovery systems work more efficiently when there is more waste heat to be absorbed, and would hence be of more use in high heat loss areas such as kitchens. 4. Disadvantages of the Use of PCMs Most buildings are built with the intention of them ...
