Where to Add Refrigerant Oil for Car Air Conditioning?
2 Answers
Car air conditioning systems are generally charged from the low-pressure side. Below is relevant information about car air conditioning: Introduction: The car air conditioning device (air-conditioning-device), referred to as car air conditioning, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions. It typically includes a refrigeration unit, heating unit, and ventilation system. This integrated system makes full use of the limited space inside the car, featuring a simple structure and ease of operation, making it a popular modern car air conditioning system internationally. Maintenance Methods for Car Air Conditioning: Comprehensive inspection of the air conditioning system. When using the air conditioning for the first time in summer, it is advisable to inspect the system first, such as checking the refrigerant through the liquid storage tank, whether the air filter is too dirty, or if there are any foreign objects in the radiator. Pay attention to cleaning the air conditioning. The air filter should be replaced regularly, and the condenser should also be cleaned periodically. After parking, do not turn off the air conditioning immediately. Drivers should turn off the cold air a few minutes before reaching their destination and switch to natural wind to allow the temperature inside the air conditioning pipes to rise, eliminating the temperature difference with the outside environment, thereby maintaining the relative dryness of the air conditioning system and preventing mold growth.
I've been driving for over a decade and have personally added refrigerant oil to my car's AC system. It's usually added through the high-pressure side port of the AC compressor, where there's a dedicated small hole that can be accessed with specialized tools. The entire process requires extra caution because refrigerant operates under high pressure - leaks not only reduce efficiency but can also cause harm or environmental pollution. The refrigerant oil serves to lubricate the moving parts inside the compressor, preventing wear and overheating. Remember to check the system for any leaks before operation, as low oil levels often indicate leakage somewhere. For tools, just purchase a refrigerant charging kit that includes connecting hoses and valves. Safety tip: Wear protective gloves, work in a well-ventilated area, and proceed slowly without rushing. It's best to consult the vehicle manual to confirm the exact location, as designs may vary between different car models. After trying it myself several times, I've concluded that professional service might be preferable to avoid repeated failures and wasted time.
