Pre-cooling humidification device for differential pressure pre-cooling vehicle

The utility model provides a pre-cooling humidification device for a differential pressure pre-cooling vehicle. According to the technical scheme, the pre-cooling humidification device comprises a refrigeration compressor, a plunger pump and a water tank communicated with the plunger pump; the refrigeration compressor is communicated with a micro-channel air cooling heat exchanger for cooling refrigerating fluid, the micro-channel air cooling heat exchanger is communicated with a high-pressure liquid storage device, and the high-pressure liquid storage device is communicated with an air cooler with a frequency converter; a liquid supply electromagnetic valve is arranged between the high-pressure liquid storage device and the air cooler, the air cooler is communicated with the refrigeration compressor, and the high-pressure liquid storage device is further communicated with the refrigeration compressor through an expansion valve; a controller is electrically connected with the liquid supply electromagnetic valve, is connected with a temperature and humidity sensor, and is further electrically connected with the plunger pump. By means of the pre-cooling humidification device in the scheme, the original flavor quality of fruits and vegetables is kept, the damage rate is reduced, the energy consumption is reduced, and the fruits and the vegetables can be rapidly and conveniently conveyed to consumers.
