Abstract

A snowmaking machine with a high snowmaking rate and its control method and working method, the snowmaking machine includes a barrel, a fan, a nozzle, a gas-liquid nuclear device, an air nuclear device, an air compressor, a temperature and humidity sensor, and a flow regulating valve , and the control module; the control module receives the signal from the temperature and humidity sensor, and controls the opening degree of the flow regulating valve in combination with the ambient wet bulb temperature. The snowmaking machine proposed by the present invention adds an air nucleator at the rear end of the nozzle and the gas-liquid nucleator, and the air nucleator can make the compressed air throttle and expand to a lower temperature, promote the nucleation of the atomized water droplets without nucleation, and can also The ice particles that promote nucleation rapidly grow into snowflakes. Compared with the prior art, the snow making machine of the present invention can effectively improve the snow making efficiency and quality of the snow making machine.

Description

technical field

[0001] The invention relates to the technical field of snowmaking machines, in particular to a high snowmaking rate snowmaking machine and its control method and working method. Background technique

[0002] Artificial snowmaking equipment is mainly snowmaking machines. There are about 4,000 snowmaking machines in my country, including 3,500 imported snowmaking machines and only 500 domestic snowmaking machines. Weather data show that, on average, the global climate is warming. Winters are getting shorter and natural snowfall is falling. It is estimated that a 1Β°C increase in average temperature would shorten the ski season by about 25%. This means that the period of artificial snowmaking is longer, and the natural conditions of snowmaking are more harsh. At present, the global ice and snow industry is in a critical stage of upgrading and development. Especially with the Beijing Winter Olympics in 2022 and the realization of the goal of "300 million people...
