PCM selection

  1. Jan 27, 2005 #1
    im working on building a simple thermal energy storage system...im using water as phase change material.The PCM will be injected into spherical capsules and dropped into a storage tank.Now my problem is that the freezing process initiates only at arnd -12 C.Remember it is under pressure..
    Though im not filling the capsule completely.I need to add some quantity of additives to raise the freezing point of water and get it back to 0 c....
    Silver Iodide i cannot use since the solution cannot be properly injected into
    my spherical capsules.......any ideas?
    what additive should i add ?
