Description

<p>As one of supercooling cancellation devices for refrigerant PCM, authors have proposed a capsule type of the device which have an elasticized membrane with a pore at one side and water is enclosed inside. Water in the capsule solidifies first because the melting point is higher than that of the refrigerant PCM. When a membrane expands by solidification, a pore opens, and the ice in the capsule is exposed to PCM. When PCM is in a supercooling state, the exposure becomes an ice nucleus, and solidification propagates. However, the concentration in the capsule rises when the exposure is too big. In this study, the influence of the difference in thickness of the membrane and the location and the orientation of the pore on the membrane on the performance of suppressing the supercooling of PCM was examined.</p>
