ABSTRACT:
A latent heat storage apparatus is provided and a latent heat storage solution therefor stores and retrieves a cool heat substantially in or from a latent heat thereof necessary for air conditioning, cooling, refrigerating, and so forth. The latent heat storage apparatus has an aqueous solution of a plurality of inorganic salts as a latent heat storage solution in a heat storage tank, formed to retrieve a cold heat from a stored latent heat, the latent heat storage apparatus. The latent heat storage solution is formed of (N-1) kinds of inorganic salts in at least an N-component aqueous solution where N.gtoreq.3. The latent heat storage solution stores the cold heat as the latent heat thereof. The cold heat is retrievable from the stored latent heat at a desired temperature almost invariably within a range higher than the N-component eutectic point and lower than any one of binary eutectic points of salts with water. The concentration of each inorganic salt in the aqueous solution is represented in a tortuous eutectic plane including ice point of the N-component equilibria diagram, wherein the concentration range allows the cold heat to be retrieved at the specified temperature almost invariably from the latent heat of ice, binary eutectics with water and inorganic salts, or separated substances.
