Hydroenergy vaporization ice-making device and control method thereof

Abstract

The invention discloses a hydroenergy vaporization ice-making device which comprises an ice crystal generator, an ice water pump and an ice crystal pump, wherein an ice water nozzles, vaporization nozzles and a water baffle grid are arranged inside the ice crystal generator; the ice water nozzles are arranged at the lower part of the ice crystal generator; the vaporization nozzles are arranged at the upper part of the ice crystal generator; an exhaust opening is further formed in the ice crystal generator and is used for exhausting vapor generated after the water inside the ice crystal generator is vaporized; the absolute pressure inside the vaporization is 611 Pa; the ice water pump is respectively connected with the lower part of the ice crystal generator, the ice water nozzles and the vaporization nozzles, and is used for pumping ice water into the ice crystal generator; the ice crystal pump is connected with the ice crystal generator and is used for sucking out a mixture of ice crystals and water generated in the ice crystal generator. The invention further provides a control method of the hydroenergy vaporization ice-making device. By the adoption of the device, not only is the ice blocking phenomenon avoided, but also the phenomenon of thermal resistance of ice layers is eliminated.

Description

Technical field [0001] The invention relates to the field of ice making, in particular to a water energy vaporization ice making device and a control method thereof. Background technique [0002] There are many methods for preparing ice crystals, such as scraping method, direct contact method, supercooled water method, fluidized bed method, etc. However, the above-mentioned methods for making ice crystals have many disadvantages: ice making by scraping method must be equipped with an external motor-driven rotating blade, and its structure and manufacturing process are complicated, energy consumption is high, and failure rate is high. The direct contact method requires that the two media in contact do not dissolve each other, so the choice of refrigerant is narrow, and there is a problem of performance degradation after a period of operation. The supercooled water method has high control accuracy and is difficult to achieve, and there are frequent ice blockages in the ice making ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned methods for producing ice crystals have many disadvantages: the scraping method must be equipped with an external motor to drive the rotating blades, and its structure and manufacturing process are complex, energy consumption is large, and the failure rate is high.

[0003] To sum up, the above-mentioned preparation methods of ice crystals all require low evaporation temperature of the ice making unit and low COP (Coefficient of Performance) of the system operation.
