In the area of food transportation, demand for cold boxes is increasing nowadays. Fixing the melting temperature of refrigerant can be designed by changing the concentration of the solution such as sodium chloride solution. Refrigerant in a cold box is necessary to be frozen before the use in order to store the latent heat. However, supercooling phenomenon prevents the cold box from solidification at freezing temperature. In the previous research, one of authors has proposed an idea of suppressing the supercooling using a capsule having a membrane as a part of the capsule. The membrane was made of elastic styrene elastomer with a pinhole on it. In this research, a method to make a pinhole and its size were varied, and propagation of freezing was observed. The degree of supercooling at propagation and the concentration of water in the capsule after the melting were investigated. It was found that if the size of a pinhole was too small, there was no propagation. On the other hand, if the size was too big, concentration of water in the capsule increased. Moreover, even the size of the pinhole is identical, the probability of propagation and the final concentration differ according to the tip shape of the copper wire which is used for making a pinhole. Hence, the optimum condition for the pinhole was clarified.
