Ultrasonic snowmaker applied to variable environment temperature and control method

Abstract

The invention discloses an ultrasonic snowmaker applied to variable environment temperature and a control method. The snowmaker comprises a nozzle, a nucleon device, a central nucleon device, an air compressor, a water pump, an air duct body, a frequency conversion fan, an ultrasonic transducer, a control module and a temperature and humidity sensor; the switching of two working modes, namely a high-temperature snow making mode and a low-temperature snow making mode, is realized through the temperature sensor and the control module; when the snowmaker is in the low-temperature snow making mode, the ultrasonic transducer is turned off; and when the snowmaker is in the high-temperature snow making mode, the ultrasonic transducer is started and emits ultrasonic waves, the ultrasonic waves act on water mist sprayed out of the nozzle and crystal nucleuses sprayed out of the nucleon device and the central nucleon device, droplet nucleation is promoted, and meanwhile existing crystal nucleuses are promoted to grow rapidly. According to the ultrasonic snowmaker, stable and efficient snow making of the ultrasonic snowmaker can be effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and low temperature, and in particular relates to an ultrasonic snowmaking machine and a control method applied to variable ambient temperature. Background technique [0002] With the continuous popularization of skiing, snow appreciation and skiing in the north in winter are becoming more and more popular, and there are more and more ski resorts in various places. The mechanism research of snow making process of snow making machine has attracted the attention of many scholars. At present, the snow production method of mainstream snowmaking machines is that the water mist from the nozzle and the water mist containing ice crystals from the nuclear device collide and combine under the blowing of the fan to promote the growth of ice crystals and realize the snowmaking function. However, the technology at this stage is limited by the temperature. The currently recognized wet bulb temperature for...

Problems solved by technology

However, the technology at this stage is limited by the temperature. The currently recognized wet bulb temperature for snow formation is -2°C. When the wet bulb temperature is higher than -2°C, the snow formation effect is very poor.
