Product name: Ｃarrier frozen oil Product brand: Carrier Product model: 101 / 103 / 110 

Product introduction: The oil used for the lubrication of the moving parts in the refrigeration compressor is called chilled oil. In the compressor, the chilled oil mainly has the functions of lubrication, sealing, cooling and energy regulation. product function: (1) Lubrication chilled oil plays a lubricating role in the operation of the compressor to reduce the operating friction and wear degree of the compressor operation, so as to prolong the service life of the compressor. (2) sealing freezing oil plays a sealing role in the compressor, so that the piston between the compressor and the cylinder surface, between the rotating bearings, to prevent refrigerant leakage. (3) When the cooling and freezing oil is lubricated between the moving parts of the compressor, it can take away the heat generated in the working process, so that the moving parts can maintain a low temperature, so as to improve the efficiency and reliability of the compressor. (4) Energy regulation For the refrigeration compressor with the energy regulation mechanism, the oil pressure of the frozen oil can be used as the power of the energy regulation machinery. request for applications: (1) The temperature at which the frozen oil is cooled down to stop the flow under the experimental conditions is called the freezing point. The freezing point of frozen oil used in refrigeration equipment should be lower, the better (such as the compressor of r22, frozen oil should be below-55℃), otherwise it will affect the flow of refrigerant, increase the flow resistance, thus resulting in poor heat transfer effect. (2) Viscosity frozen oil is an important parameter in the viscosity characteristics of the oil, using different refrigerants to choose different frozen oil accordingly. If the viscosity of the frozen oil is too large, the mechanical friction power, the friction heat and the starting moment will be increased. On the contrary, if the viscosity is too small, it will not form the required oil film between the moving parts, so as not to achieve the due lubrication and cooling effect. (3) turbidity point The turbidity point of the frozen oil refers to the temperature of the frozen oil when the temperature drops to a certain value, and the lubricating oil becomes cloudy. The turbidity point of the chilled oil used in the refrigeration equipment should be lower than the evaporation temperature of the refrigerant, otherwise it will cause the throttle blockage or affect the heat transfer performance. (4) Other properties such as chemical stability and oxygen resistance, moisture and mechanical impurities, and insulation performance. (5) The flash point of frozen oil refers to the very low temperature when the lubricating oil is in contact with the flame. The flash point of chilled oil used in refrigeration equipment must be more than 15~30℃ higher than the exhaust temperature to avoid the combustion and coking of lubricating oil.
