Air conditioner dryer - when to change it?

For most drivers, air conditioning is the main piece of equipment in a car. It works well not only in hot summer, giving a pleasant coolness, but also in autumn and winter, when it effectively helps to get rid of the burdensome moisture during this period. The air conditioner's dehumidifier is responsible for absorbing water from the air, which, like the coolant, requires regular replacement. When is it necessary and what rules should be followed when installing a new filter?

What will you learn from this post?

• What is the function of a dehumidifier in an air conditioning system?
• When should the air conditioner filter be replaced?
• Why is it so important to regularly change the air conditioner dryer?

Shortly speaking

The air conditioner dryer plays a huge role - it not only absorbs moisture that enters the system, but also filters the refrigerant from many contaminants, thereby protecting the remaining components from costly breakdowns. In a properly functioning air conditioning system, the dryer should be replaced no more than once every two years. In the event of a cooling system leak or repair of any of its key elements, this filter should be replaced with a new one (hermetically packed) immediately after the defect has been repaired.

Location and role of the dehumidifier in the air conditioning system

The dehumidifier is an essential link in the air conditioning system responsible for trapping the compressor, which is harmful to the compressor (and other corroded metal parts). moisturewhich may appear as a result of improper installation, replacement of one of the key elements of the air conditioning system or a leak in its system.

A drier (also known as an air conditioner filter and drier) is usually located between condenser and evaporator and can be in the form of a small aluminum can, a plastic liner, or an aluminum bag. Its inner part is filled with a special moisture-absorbing granulate.

It not only dries but also filters

The second important task of the dehumidifier is filtration of refrigerant from impurities – fine solids, sawdust or deposits that, when accumulated in large quantities, block the air conditioning system and reduce its effectiveness. As a consequence, this can lead to costly failures of other components, including the expansion valve and evaporator.

Interesting fact:

Some models of dehumidifiers are optional. refrigerant level sensor circulating in the air conditioning system, which allows you to control the amount of fluid on a constant basis and accurately determine the date of its next replenishment.

When do you need to replace the air conditioner dryer?

The first primary signal that the air conditioner dryer needs to be replaced is opening the system to keep you cool in the cabin. The "left" air entering its channels is a huge source of moisture, so the granules inside the air conditioner filter reach their maximum absorption level faster.

The second reason to replace the dehumidifier with a new one is serious interference with the air conditioning system – repair or replacement of the compressor (compressor) or condenser exposes the water-absorbing filter to a large amount of moist air. The granulate used is dehumidifier becomes uselesstherefore, its replacement is essential for the correct and safe functioning of the air conditioning system. The cost of a new filter is relatively low compared to the cost of repairing or replacing major cooling system components, where excessive moisture can cause significant damage.

What if the air conditioner works flawlessly?

Remember that the air conditioner dryer is a consumable item that, like coolant, must be checked and replaced regularly. Even in a new, sealed and well-functioning system, the desiccant granulate does not perform its function after a while. Dehumidifier manufacturers and reputable air conditioners recommend filter replacement with a new maximum every two years... We follow their opinion, guided by the principle that it is better to prevent than to repair.

Important rule of thumb when installing an air conditioning dehumidifier

The world's absurdity is the proposals for the sale ... of used dehumidifiers for air conditioners. It is worth emphasizing that this type of filter absorbs moisture better than a sponge, but up to a certain point. When it reaches the level of its absorbency, it becomes useless. What's more, its cartridge also absorbs moisture from the air, which is why you need it. remove it from the hermetically sealed original packaging just before installing it into the air conditioning system (maximum 30 minutes before putting in the right place). This task should be entrusted to the professionals of authorized car services.
