Title:
HEAT STORAGE SYSTEM AND AIR CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2015210028
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To surely make a heat storage medium as hydrate slurry from an overcooling state in a heat storage tank, in a heat storage system which uses the heat storage medium in which a clathrate hydrate is created by cooling.SOLUTION: A refrigerant in a refrigerant circuit and a heat storage medium in a heat storage circuit are heat-exchanged by a heat storage heat exchanger, the heat storage medium is cooled, and the heat storage medium is brought into an overcooled state at a temperature lower than a hydrate creation temperature. After that, the heat storage medium is heated by the refrigerant in the heat storage heat exchanger, and raised in temperature to a prescribed temperature not lower than the hydrate creation temperature. By this constitution, a temperature impact arises in the heat storage tank by the flow-in of the high-temperature heat storage medium, the low-temperature heat storage medium and the high-temperature heat storage medium are mixed with each other, disturbance abruptly occurs, and the inside of the heat storage tank is agitated. As a result, hydrate slurry originally existing in the heat storage tank is largely grown up. The hydrate slurry becomes a core for eliminating the overcooling state of the heat storage medium which flows into the heat storage tank succeedingly.
