How To Put Oil In Ac Compressor

How To Put Oil In Ac Compressor – Everyone agrees that coolant is the key to a healthy system; as well as lubricating internal components of the compressor, it is also a heat absorber and sealant for rubber parts such as hoses and seals. The world of fast AC system lubricants means you can be forgiven for messing up your PAGs with your POEs, but the effect on your circuit is bad. This month’s blog looks at the different fuel technologies on the market.

According to the recommendations of the manufacturer of the compressor and the refrigerant used, there are 4 main types of oil to consider.

PAG Oil (Polyaklyene glycol) – One of the first man-made oils developed, PAG is used in R134a systems and R1234yf systems that require special PAGs. The different types of PAG such as PAG46, PAG100 and others… show different oil viscosities (the measure of the oil’s resistance to flow) and coolants designed for it. PAG oil is hygroscopic, meaning it can absorb moisture from inside air or air. Since the absorbed water remains hydrogen bonded to the ether bonds of PAG and remains immobilized by PAG, this property is very beneficial.

Mineral Oil (MO) – Although these oils are well represented in the market, they may be on borrowed time. They do not mix well with hydrofluorocarbons (HFCs) such as R134a, and although advances in engineering and technology have raised the level of lubricants, the synthetic market is leading the way.

PAO Oil (Polyalpha Olefin) – A mineral synthetic oil commonly used in automotive applications, PAO has low hygroscopicity properties and does not introduce unwanted moisture when added to the system. Although not approved by the manufacturer as an AC oil, ISO 68 grade PAO is often used in mobile shops as a “universal” compressor oil.

Polyol ester or POE is a fully synthetic lubricant developed for systems using HFC refrigerants. POE provides high lubrication and chemical stability to system components and also provides good miscibility (the ability to mix refrigerant and HFCS). Made from a reversible chemical reaction between an acid and an alcohol to form a polyol ester and water, POE grease is less hygroscopic than PAG grease, but when exposed to large amounts of water it can there will be a natural reverse reaction that leads to acid formation and destruction. the structural element. PAG oil is not subject to the same chemicals.

TOP TIPS! – Avoid mixing PAG with universal oils. At first glance, these two oils seem to mix well, but don’t forget! It is certain that they cannot form a long-term homogeneous mixture and separate after a short time when the compressor is not running. Therefore, when starting the compressor from cold, the different density and viscosity of the oil will lead to improper lubrication inside the AC compressor, which will lead to friction, overheating and seizure. .

It needs a lot of oil, just like your car engine. If you don’t want to suffer from unexpected failure of your heating system, you need to have an idea about its quality.

Generally, you do not need to add oil to your AC compressor after installation, unless you are installing a new compressor or if there is a fault in your AC system. If you need to add more oil, refer to the compressor instructions for the required amount of oil.

For a new compressor, find the specifications for your AC system. A typical car may use a small amount of oil (4 oz.) and two cans of R-134a refrigerant (12 oz.). ).

If there is a leak in my AC system, it is better to fix the leak and then deal with the fuel requirement. Well, let’s talk about how you can prevent your plumbing system from malfunctioning and keep things running smoothly.

Your car’s air conditioning compressor should be serviced regularly by having it inspected on its own or by going to a mechanic for a vehicle inspection.

Your air conditioning system uses a compressor that works like an engine and needs oil for lubrication. The compressor helps to pressurize the gas in the AC which expands later, resulting in cooling. As the gas expands, the gas becomes hot. Your car’s AC can keep you cool as the air is drawn in by the cold gas in the evaporator.

You may be surprised to know that an AC compressor has cylinders just like a car engine, except that these cylinders help compress gas. It works hard to pressurize the coolant in the system and needs oil to control heat and lubrication.

Repeated pressure, expansion and recirculation of refrigerant in the system can cause stress on the system if not properly maintained.

If the AC isn’t as cold as it used to be, you may have a leak. One reason your AC isn’t cooling properly is a system leak. If you are trying to repair the leak, you should be very careful, because no one can be sure how much coolant is missing.

If you fix the leak and add the AC refrigerant, you should know that there is a risk.

AC refrigerants contain oil, and adding too much can cause the compressor to malfunction or cause leaks due to excessive stress.

If you don’t have enough, the AC compressor may be overheating or have a mechanical fault.

Balancing Refrigerant Oil Like A Pro

First, the refrigerant is compressed by your AC compressor, which raises the temperature. It is then mixed in the condenser. The receiver collects and turns it into liquid. It is then allowed to expand, cooling as it passes through the evaporator. Then the gas is compressed again.

As the low-pressure refrigerant returns to the compressor, it enters the inlet area, is compressed, and exits the outlet side as a high-pressure gas.

Over the past two decades, the automotive industry has used R134a refrigerant extensively. After 2015, the refrigerant was improved by installing the new refrigerant R-1234yf, which protects the environment.

Advances in refrigerants have also changed the oil used in compressors. PAG (polyethylene glycol) oil is the best replacement for old oil. R-1234yf also requires PAG oil. PAG oils have different viscosities, eg. PAG 100 and PAG 150. If your air conditioning system is not OE supplied, you should choose PAG 100 for R-134a, as technicians often use it due to its universal viscosity.

Proper maintenance is necessary to maximize your compressor’s efficiency and long-term compressor operation. Using a lot of oil inside the compressor increases its efficiency, and the components of the AC system work smoothly and smoothly with noise-free starting.

If you add too much lubricating oil to the compressor, it will reduce its cooling capacity. It also creates unwanted cavities inside your compressor, reducing heat transfer between the atmosphere and the system.

In general, you should add as much oil as the compressor needs. This will ensure that the compressor starts properly, and that the fuel is evenly distributed throughout your vehicle’s ignition system.

Now you have a brief idea about the importance of oil for your AC compressor and how to maintain your car’s air conditioning system. The oil in your compressor has a significant impact on the life of the system. Therefore, you should always keep the air compressor measuring and add the right amount of oil when needed.

Refrigerant Oil Basics

As I mentioned above, a faulty compressor causes problems with your AC system. If you need a mechanic to repair your AC compressor, it is better to buy a new one, because the parts and labor make it a more efficient and reliable method.

You should follow your vehicle’s instructions when oiling a new or old compressor. I hope the information and instructions provided in this blog will help you find a solution to your problem.
