The method of adding chilled oil to household air conditioners is as follows:
< br >
Clean the refrigerant of the air conditioner; Vacuum treatment of air conditioning; The air conditioner refrigerant charging valve is connected to the refrigerant oil with a hose; Put the refrigerant oil on the electronic scale; Open the charging valve; The air conditioner automatically pumps oil until the amount of oil meets the requirements; Close the charging valve; Fill the air conditioner with refrigerant.

The requirements for freezing oil are as follows:
< br >
1, turbidity point: the turbidity point of the refrigeration oil used in the refrigeration equipment should be lower than the evaporation temperature of the refrigerant.
< br >
2, freezing point: the freezing point of the refrigeration oil used in the refrigeration equipment should be as low as possible, otherwise it will affect the flow of the refrigerant, increase the flow resistance, resulting in poor heat transfer effect.
< br >
3, viscosity: If the viscosity of the frozen oil is too large, it will increase the mechanical friction power, friction heat and starting torque. On the contrary, if the viscosity is too small, the required oil film cannot be formed between the moving parts, so that the lubrication and cooling effect cannot be achieved.
< br >
4, flash point: the flash point of the refrigerated oil used in the refrigeration equipment must be higher than the exhaust temperature of 15 to 30 degrees Celsius, so as not to cause the combustion and coking of lubricating oil.
