Abstract
A cold storage system and method are provided. The cold storage system includes a chiller, a hydrate-based cold storage tank, a gas disturbance generator, a concentration detector, a heat exchanger, a direct-current power supply and circuit controller, and a system monitor. Chiller provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through a coil in the hydrate-based cold storage tank for a heat exchange. The gas disturbance generator induces hydrate nucleation. The concentration detector monitors a concentration of a hydrate solution in real time. The heat exchanger is equipped with a finned tube heat exchanger with a fan, to improve the cold supply efficiency of the cold storage system. The system monitor monitors a state change of the system in real time through a set of temperature-pressure sensor modules. Several cold energy supply modes can be realized in the present disclosure by adjusting opening/dosing of valves.
