Snow seed oil is the abbreviation of lubricating oil for air conditioning compressor. It is a highly refined, non foaming, non wax, water free lubricating oil. As the key equipment of the air conditioning system, the air conditioner compressor must be lubricated to reduce friction and increase sealing performance. Therefore, a certain amount of lubricating oil must be kept in the air conditioning system.
In addition to the lubrication, sealing, cleaning and other functions of the common lubricating oil, the snow seed oil has strong water absorption performance compared with other lubricants. Moisture is the enemy of air conditioning refrigeration system, such as moisture and refrigerant combination, it will produce hydrogen chloride and corrosion components, and will cause expansion valve blocked due to icing. And a small amount of snow seed oil and refrigerant cycle in the refrigeration system, can play a role in moisture absorption. Therefore, the snow seed oil in the production process is treated by dehydration, usually use should pay attention to sealing, to prevent the absorption of water vapor in the air.
