Abstract: An internal circulation type clathrate hydrate-based cold storage system and method are provided in the field of industrial refrigeration. The internal circulation type clathrate hydrate-based cold storage system includes a water chilling unit, a hydrate-based cold storage tank, a gas disturbance device, a concentration measurement system, a heat exchange system, a direct-current power supply and circuit control system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for a heat exchange. The gas disturbance device induces hydrate nucleation. The concentration measurement system monitors a concentration of a hydrate solution in real time. The heat exchange system is equipped with a finned tube heat exchanger with a fan. The system monitoring device monitors a state change of the system in real time through a plurality of temperature-pressure sensor modules.
