The storage temperature of wine is 50-68 °F, and the ideal humidity is between 30% and 80%. The flavor of wine is astringent and excessive oxidation may cause wine to deteriorate under high temperature. Too little humidity will affect the sealing effect, allow more air to contact with wine, accelerate oxidation and cause wine to deteriorate. Breweries generally store wine in cellars and use air conditioners to cool down, which is not only easy to breed microorganisms, but also costs a lot every year.Vanse researched and developed the hvls fan based on aerodynamics and aviation technology. When the fan is running, massive airflow is generated through the slow rotation of the blade, which is pushed to the ground in a cone shape from ceiling, and then flows horizontally. It will be pushed upward to the ceiling after encountering the horizontal airflow, so as to strengthen the air circulation with all-direction, multi angle and no dead corner, eliminate stratification, and keep temperature and humidity consistent.
