CLATHRATE HYDRATE HAVING LATENT HEAT STORAGE PERFORMANCE, SYSTEM FOR PRODUCING THE SAME, LATENT HEAT STORAGE MEDIUM, AND TREATMENT SYSTEM FOR INCREASING LATENT HEAT STORAGE LEVEL OF CLATHRATE HYDRATE

摘要

PROBLEM TO BE SOLVED: To provide a clathrate hydrate having latent heat storage performance with a quaternary ammonium compound as a guest, high in heat storage density and capable of keeping its own favorable fluidity even when used as a heat transfer medium, to provide a method for producing the clathrate hydrate, and to provide a production system for the clathrate hydrate.SOLUTION: The clathrate hydrate, which has latent heat storage performance with a quaternary ammonium compound as a guest, is characterized in that the latent heat storage performance has been increased by including, in addition, a gas fed from the outside as another guest. The production system for producing the clathrate hydrate is also provided, being characterized by having: a mixer 5 for feeding the gas into an aqueous solution containing the quaternary ammonium compound to mix the gas into the aqueous solution; and a generator 9 for producing the clathrate hydrate increased in the latent heat storage performance through cooling the resultant aqueous solution mixed with the gas.
