Auto AC Tools: Filter Driers

Learn more about Auto AC Tools: Filter Driers in this article!

Although receiver-driers are not the most sophisticated component of a car air conditioner, they still perform critical roles and needs changing if they risk causing system harm. Learn about one of the important auto ac tools, the filter driers in this article.

WHAT ARE FILTER DRIERS?

Drier change requirements are the top cause of expensive system failures, so get yours altered today! The condenser and the TX valve are receiver-driers, also known as filter-driers. They get their name from how they 'filter' tiny dirt and 'dry' moisture out of the system. The accumulator, which works similarly to a receiver-drier but in a different system arrangement, is another component of the AC drier. These components are just as vital to replace your engine's oil filter and have a two-year lifespan.

Filter driers are a component that safeguards the A/C loop's other details. It's on the high-pressure side of the circuit, between the condenser outlet and the expansion valve inlet. The receiver drier serves a variety of purposes:

  • During the receiver drier's lifetime, to keep moisture and impurities out of the system.
  • Complete the condensation of the fluid.
  • To account for fluctuations in fluid volume.
  • To guarantee that oil returns to the compressor, replacing the filter frequently helps avoid major breakdowns. It also avoids the expensive replacement of other aircon system components.

FUNCTIONS OF FILTER DRIERS

The filter-drier is a component of the air conditioning system that receives liquid refrigerant from the condenser and serves two basic functions:

  • To remove contaminates. (This is where the majority of bigger pollutants will end up.)
  • To get rid of any remaining moisture in the system.

Moisture is the top enemy of an a/c system. Hence, removing it is vital. When mixed with refrigerant and lubricant, moisture becomes acidic (hydrochloric acid) and begins to eat away at the components from the inside out. There are desiccant substance in filter driers to absorb moisture and avoid acid accumulation in system components. It's a one-time-use substance that eliminates the rest of the moisture remaining in the aircon system after evacuation. The desiccant placed inside the filter-drier removes any remaining moisture in the system that evacuation does not remove. It would help replace the filter-drier whenever the system is exposed to the atmosphere.

Inside the filter-drier, there is also a screen to trap microscopic contaminating particles that can trigger component failure. To provide a guarantee, many technicians might require a system flush in addition to replacing a broken item and the filter-drier.

WHEN DOES IT NEED REPLACEMENT?

If you opened and exposed the air conditioning unit, the desiccants will quickly collect any moisture present and get saturated. It reduces the drier's performance. If the receiver-drier can no longer remove moisture from the liquid refrigerant as it goes through, major damage to the compressor and other sections of the air conditioner could occur, which would be far more costly to replace than the drier assembly itself.

Loss of charge in the refrigerant and internal compressor failures, which can allow small bits of metal to travel through the system and block the filtering element of the filter-drier, limiting refrigerant flow, are other reasons to replace the drier.

REPLACING AUTO AC TOOLS: FILTER DRIERS

The drier is a small component usually readily for inspection, removal, and replacement as part of periodic maintenance. To maintain the system functioning at maximum efficiency and to remedy any small defects before they become more serious, professionals advise that the filter-drier needs replacement every two years. Also, the air-conditioning system needs servicing every year.

When you open the circuit, you should replace the filter driers. Suppose the condenser is destroyed as a result of an accident. In that case, you must change it, or the desiccator may lose its ability to keep humidity in the circuit and become saturated. Because the receiver-drier is hygroscopic, it performs a critical role. As a result, following the basic regulations when replacing a vehicle is vital. Otherwise, it may damage the replacement receiver drier. Receiver driers come with mandatory plugs that must be eliminated as soon as possible, ideally right before installation.

HVAC Shop's Auto A/C Tools: Filter Driers

Accumulators and filter-driers play a crucial part in A/C operation, although they are sometimes missed during routine vehicle maintenance. These components control the liquid, and vapour refrigerant flows through the unit, ensuring maximum output and uninterrupted operation.
