What is the function of refrigeration oil?
4 Answers
The functions of refrigeration oil are: 1. To lubricate the compressor during operation, reducing friction and wear; 2. To provide sealing between the piston and cylinder wall, as well as between various rotating bearings in the compressor; 3. To carry away the heat generated during operation when lubricating various moving parts in the compressor, keeping these components at a lower temperature; 4. To utilize the oil pressure of the refrigeration oil as the power source for energy regulation mechanisms. The oil used for lubricating moving parts in refrigeration compressors is called refrigeration oil, also known as compressor oil or refrigeration lubricating oil.
Refrigerant oil is truly a critical component in a car's air conditioning system. It primarily lubricates the internal parts of the compressor, ensuring smooth operation of pistons and bearings without jamming. Every time I use my car, I pay attention to the sound of the AC - excessive noise often indicates insufficient or depleted refrigerant oil. It also helps seal the compressor's gaps to prevent refrigerant leaks, which directly impacts cooling performance. Driving without cold air in summer is pure torture, often caused by refrigerant leaks depleting the oil's protective properties. Additionally, refrigerant oil aids heat dissipation, preventing compressor overheating and burnout. Through years of driving older vehicles, I've learned the hard lesson of regularly checking refrigerant oil levels - typically replacing it every two years or as per the manual, otherwise compressor replacement costs dearly. For daily maintenance, remember to avoid frequent AC cycling to reduce oil consumption and maintain system health for extended longevity.
I've been driving an SUV for five years, and the role of refrigeration oil for me is to protect the heart of the air conditioning system—the compressor. It lubricates the internal rotating components, making operation quieter; at the same time, it provides sealing to prevent refrigerant leaks, which is especially important during long trips to avoid the hassle of stopping midway to repair the air conditioning. I've also experienced issues with aged refrigeration oil, which also helps cool the compressor, reducing the risk of heat damage. If neglected, the compressor could suffer severe wear or even damage. I recommend having a technician check the refrigeration oil condition during every maintenance service, typically replacing it every two years, with a pre-summer inspection being the most practical.
The main functions of refrigerant oil in a vehicle's air conditioning system are to lubricate the compressor and prevent component wear; it also seals gaps to avoid refrigerant leakage, ensuring proper cooling operation. From my personal experience, it also aids in heat dissipation, making the system run more stably. Remember to check and replace it regularly.
