In a split system air conditioner, the lubricating oil supply line is typically connected to the compressor. The compressor is the heart of the air conditioning system and is responsible for compressing the refrigerant gas, which raises its temperature and pressure before it moves to the condenser for heat exchange.
The lubricating oil is crucial for the proper functioning and longevity of the compressor. It ensures that the moving parts inside the compressor remain well-lubricated, reducing friction and wear on the components. This is especially important because the compressor operates at high speeds and under significant pressure.
In a split system air conditioner, the compressor is usually located in the outdoor unit (condensing unit) along with the condenser coil and a fan. The lubricating oil supply line connects to the compressor's oil sump, ensuring a steady supply of oil to keep the compressor running smoothly.
During the installation and maintenance of the air conditioner, technicians take care of checking the oil levels and, if necessary, adding or replacing the oil to maintain the compressor's proper function. The oil should be compatible with the refrigerant used in the system and meet the manufacturer's specifications.
Keep in mind that split system air conditioners are complex machines, and any maintenance or repair work involving the compressor and its lubricating oil should be carried out by a qualified HVAC professional.
