Problems solved by technology
The existing device blows air at the bottom of the ice storage coil to increase the disturbance, which can greatly improve the ice-melting rate and the uniformity of ice-melting. The improvement of the thermal effect is not obvious, and the disturbance speed of the ice water should not be too large, which will easily cause the water flow to mix back, which is not conducive to the external melting of ice.

The invention relates to an external ice-melting ice storage device capable of automatically adjusting the air blowing volume. An air compressor is connected, the air compressor includes an air return pipe, a pressure sensor is arranged on the air return pipe, and a frequency converter is connected to the air compressor; the advantages of the present invention: the liquid level information in the ice storage tank is collected in real time through the liquid level sensor , The pressure change in the return air pipeline is collected in real time through the pressure sensor set on the return air pipe. The frequency converter receives the information of the liquid level sensor and the pressure sensor at the same time, and comprehensively controls the air pressure according to the ice water level height and the air return line pressure change. The speed of the machine is adjusted, so as to realize the automatic adjustment of the air volume of the air blowing component, so as to ensure that there is enough air volume and a certain pressure of air to be blown into the ice water when the ice storage volume is different, which will cause a certain disturbance to the ice water and improve the ice melting efficiency. , shorten the melting time.
Description
technical field [0001] The invention relates to the technical field of ice storage, in particular to an external melting ice ice storage device capable of automatically adjusting the air blowing volume. Background technique [0002] Ice storage technology can use the latent heat of phase change from water to ice for cold storage, and store the power ice-making at night in the low valley load in the ice storage device, and melt the ice during the day to release the stored cold energy, reducing the power consumption of air conditioners during the peak hours of the power grid. load and the installed capacity of the air-conditioning system, to achieve the role of "shaving peaks and filling valleys" and balancing the power load. At present, the coil-type ice storage tank is mostly used in the ice storage technology. The ice-melting method is divided into internal ice melting and external ice melting. The ice on the outer surface of the tube gradually melts to cool the coolant fo...
