Description
[ technical field ] A

[ background of the invention ]
The ice storage device uses cheap electric power in low load period of power grid, such as night electric power, and stores cold energy produced by refrigerating system in water by using secondary refrigerant (usually glycol aqueous solution) to freeze water into ice. And in the high load period of the power grid with expensive electricity price, such as daytime, the cold energy in the ice is released, so that the requirement of the high load period of the power grid on the electric power is reduced, and the 'peak load shifting' of the power system is realized. In areas with power supply shortage, the ice storage device can realize load transfer, namely, cold load in the peak period of power supply is transferred to the low-ebb period of power load, so that the energy utilization efficiency is improved, and the problem of power supply in the peak period of power supply is solved. Therefore, the technology is greatly supported by the popularity of users and the power policy of the power department, and is rapidly developed in China.
In the related art, the operation support data of the ice storage device is acquired by various sensors arranged on pipelines and boxes around the device, and then signal wires of the sensors are led to a main control cabinet of an air conditioning system to realize the operation support data. However, the ice storage device is generally far from the main control cabinet of the air conditioning system, so that a large error exists between the real-time operation data acquired by each sensor and the data acquired, analyzed and calculated in real time, and the high-proportion value correction needs to be performed on the parameters of each sensor in the main control system of the air conditioning system, so that the possibility of instability of the system operation is increased easily. In addition, the length of the signal line of the sensor is too long, so that the acquired data is delayed and the correction proportion is not adjusted, the deviation of the cold accumulation and cold release capacity of the ice storage device is large, the use requirement cannot be met if the capacity is small, and the running safety risk of the ice storage device and the surrounding environment is caused if the capacity is large, so that the energy storage conversion and ice melting and cold discharging efficiency of the ice storage device are reduced.
Therefore, there is a need to provide a new automatic collecting module of ice storage device and a collecting method thereof to solve the above-mentioned technical problems.
