Description

technical field

[0001] The present invention is a method and device for making ice, especially a method and device for making fluid ice. Background technique

[0002] The ice-making process widely exists in industry and daily life, especially in recent years with the gradual implementation of time-sharing electricity prices and the increase in intensity, the use of ice storage refrigeration air-conditioning units has become more and more widespread. Cooling capacity storage, turning off the refrigeration unit when the peak electricity price is reached, and melting the ice for cooling can achieve significant economic effects.

[0003] The current ice-making technology can be summarized into the following categories:

[0004] 1 piece of ice: Pour fresh water into a metal ice mold located in low-temperature salt water to gradually cool down, freeze into ice cubes, and then place the ice mold in a higher temperature environment to release the ice. [000...

Embodiment Construction

[0026] The present invention proposes a brand-new high-efficiency ice-making method: first, the cooling medium of the fluid is cooled below 0°C through the evaporator, and the ice-making water is sprayed into the cooling medium of the cooled fluid through the nozzle to form ice particles and The mixed fluid of the cooling medium of the fluid sprays water into the cooling medium through the nozzle located in the cooling medium, and the water droplets directly contact the cooling medium for heat exchange, without heat transfer through the metal surface, and the heat transfer intensity is large. During the flow, the water droplets are cooled by the surrounding low-temperature cooling medium and freeze into ice particles. The size of ice particles can be adjusted through the atomization nozzle and atomization pressure. The time required for water droplets to freeze into ice particles mainly depends on the temperature of the cooling medium and the size of the water droplets. For exa...
