The role of compressor
The compressor is an essential component of the air conditioning
system in a vehicle. Its primary function is to circulate and
compress the refrigerant gas, which is responsible for cooling and
dehumidifying the air in the cabin.
The process starts with the compressor drawing in low-pressure
refrigerant gas from the evaporator and then compressing it into a
high-pressure, high-temperature gas.
This compressed gas is then sent to the condenser, where it
releases heat and transforms into a high-pressure liquid. After
leaving the condenser, the pressurized liquid refrigerant flows
through the receiver drier or accumulator, which removes any
moisture or debris from the refrigerant. From there, the
refrigerant passes through the expansion valve or orifice tube,
which regulates the flow of the refrigerant into the evaporator.
Inside the evaporator, the high-pressure liquid refrigerant rapidly
expands and evaporates, absorbing heat from the air passing over
the evaporator's fins. This cools the air and reduces its humidity.
The cooled air is then blown into the cabin through the vents,
providing a comfortable and refreshing environment for passengers.
Overall, the compressor plays a crucial role in the refrigeration
cycle of the air conditioning system, ensuring that the refrigerant
is properly circulated, pressurized, and transformed to achieve
effective cooling inside the vehicle.
4 steps to diagnose a car air conditioning compressor problem:
Step 1: Start the engine and turn on the A/C to the highest
setting. This will activate the air conditioning compressor, which
will draw refrigerant from the evaporator at low pressure, compress
it, and send it to the condenser at high temperature and pressure.
Step 2: Listen for any unusual noises. Inspect the clamps, fixing
points, hoses, and lines for breaks, cracks, missing nuts or bolts,
and vibrations transmitted from the engine to the cabin. Check the
belt, clamping device, tensioner pulleys, and clutch for wear, as
they can cause unusual noises. If no obvious issues are found,
consult a qualified technician to further diagnose the problem.
Step 3: Check for cool air coming from the air vents. Make sure the
cooling fans operate when the air conditioner is on. Clean or
replace the cabin air filter if necessary. Remove any debris, such
as leaves, bugs, or dirt, that could obstruct airflow through the
condenser.
Step 4: Inspect for visible leaks under the car. Look for any signs
of refrigerant leakage, such as oily stains or puddles. If a leak
is detected, it is recommended to seek professional assistance to
properly diagnose and repair the issue.
