Drying bottle is a device that absorbs water by physical adsorption principle. Usually filled by polymer adsorption material, in the relatively humid environment in the car, through the polarity of the adsorption material in the drying bottle and the polarity of the water molecules in the air is different, so that the water molecules in the adsorption material inside the physical adsorption, so as to achieve the purpose of adsorption of moisture in the humid air
Maintain the stability of the air conditioning system : in the automotive air conditioning system, dry bottles store and supply refrigerant, filter impurities, and absorb moisture in the system, prevent water and ice blockage, to ensure the stable operation of the compressor and refrigeration system
Impurities : The drying bottle also has a filtration function to remove impurities in the system to ensure the purity and dryness of the system
