Claim 1:
2. The preparation method for a hydrate energy-storage temperature-control material according to claim 1, wherein generating the refrigerant hydrate in step 1 includes: {circle around (1)} cleaning and flushing the reactor by using deionized water, pouring the water into the reactor, and exhausting air from the reactor by using a vacuum pump; {circle around (2)} introducing refrigerant into the reactor, cooling the reactor to a temperature below the hydrate phase equilibrium temperature and above the freezing temperature by using a refrigeration cycle cooling system in which the reactor is placed according to the type of the refrigerant and the refrigerant hydrate phase diagram, pressurizing the reactor to the pressure point in a hydrate stabilization region corresponding to the temperature in the phase diagram after the temperature in the reactor is stabilized, and turning on a magnetic stirrer to initiate generation of the hydrate; {circle around (3)} judging whether the hydrate is initially formed through the increase of temperature in the reactor, if the temperature in the reactor suddenly increases, it is indicated that the hydrate formation reaction begins to release heat, and then if the temperature in the reactor gradually decreases until the temperature is stabilized at the original temperature within 1 h, it is indicated that a stable state is reached, and the hydrate is generated completely; measuring the temperature in the reactor by using a temperature sensor in the reactor, measuring the pressure in the reactor by using a pressure sensor, and gathering pressure and temperature signals by a data recording system and collecting same by a personal computer.
