Working principle
In a closed AC system, the cooling process of freon in the
evaporator is a result of a significant pressure change. The
high-pressure liquid freon moves through a narrow opening, which
causes it to atomize and cool rapidly. The compressor's role is to
pump the refrigerant (freon) from the low-pressure circuit
(condenser radiator) to the high-pressure circuit (evaporator
radiator), simultaneously compressing it and increasing its
temperature. The freon is then cooled and converted to a liquid
state in the condenser before reentering the system. The AC
compressor is commonly referred to as the "heart" of the system,
underscoring its vital role in the proper functioning of the air
conditioner. Consequently, the compressor experiences a significant
load as it operates.
Occurrence Of Problems
Many car owners who have not experienced air conditioner repairs might not realize how costly the procedure can be. This is why it is important to highlight the primary mistakes that can lead to numerous issues with the car's AC compressor.
1.Neglecting regular maintenance of the AC system: One common
mistake that car owners make is ignoring the annual maintenance
procedure for their AC system. This can lead to issues with freon
leakage, as rubber hoses in the system have a tolerance of up to
10% for leakage due to their porosity. By not refilling the AC
system regularly, the refrigerant levels can drop significantly
over time, affecting the cooling efficiency and putting extra
strain on the compressor.
2.Not using the air conditioner in winter: Another mistake is not
turning on the air conditioner for preventive purposes during
winter. Running the AC system periodically during the winter helps
to lubricate the internal components and maintain the tightness of
the system, preventing refrigerant leakage and corrosion. While the
AC may not work at subzero temperatures outside, it can be turned
on in a warm room such as a service station, car wash, or covered
parking. This simple operation takes around 15 minutes and can have
a positive impact on the longevity of the AC system.
3.Installing a fine-grained mesh in front of the radiator-condenser
can hinder the radiator's cooling capacity. Consequently, the
efficiency of the AC system decreases, causing the car compressor
to operate under a heavier load. As a result, the compressor and
several components of the AC system endure more strain, leading to
a reduction in their lifespan. Similar issues can arise when debris
accumulates in the radiator-condenser, particularly after spring
when it becomes congested with fluff. It is common for individuals
to overlook proper maintenance of the AC system and opt for
inexpensive alternatives instead of seeking professional help at
reputable repair stations. However, professional repair stations
possess the necessary equipment, such as charging stations and gas
analyzers, to ensure the correct refrigerant is used. Neglecting
proper maintenance procedures can result in various problems that
prevent the AC system from functioning properly. For instance,
using subpar refrigerants that may contain different types of
refrigerants can cause compatibility issues with the system's
lubricating oil. Consequently, the lubrication effectiveness of the
system decreases, and the car compressor's lifespan may be
prematurely reduced.
4.Inadequate maintenance of air conditioners, based on the
principle of cost-cutting rather than professional servicing at
recommended specialized service stations, can lead to various
violations that may ultimately disable the air conditioner. One
such violation is the use of low-quality freon during maintenance,
which may contain different types of freon that are not compatible
with the oil used in the system. While this mixture might still
meet temperature requirements, such as the boiling or condensation
point, of the standard R134a freon, it can significantly
deteriorate the lubrication system and quickly lead to the failure
of the car AC compressor.
By avoiding these mistakes and being proactive in maintaining the AC system, car owners can prevent costly repairs and ensure that their air conditioner continues to function efficiently.
