Hot summer
When air conditioner is not cooling
For car owners who travel every day
This is unbearable
Then
When machine encounters this problem
What should I do?
Let's see today
How to check that car air conditioner is not cooling
Car air conditioning does not cool
In particular, this can be divided into two situations:
①Cold air is blown out, but cooling effect is poor ②There is no cold air, and cooling effect is completely lost
The cooling effect of air conditioner is poor
Reason 1: Capacitor heat dissipation is blocked
The condenser is located next to front radiator
This is one of important parts of heat dissipation of an automotive air conditioning system
When it's covered in oil, dust, and leaves
Deteriorated heat dissipation
This will also affect cooling effect of conditioner
Clean condenser from dirt and debris in time
The cooling capacity of air conditioner can be restored quickly
Reason 2: The air conditioner filter is clogged and dirty
There is filter dust on air conditioner filter element and
Role of respirable particulate matter
After use in winter and spring
Some impurities will
Reducing wind power of air conditioner to reduce or even create a peculiar smell
Suggest car owners
Replace every 20,000 km
The air conditioner does not cool at all
When air conditioner can't cool at all
It is necessary to arrive at auto repair shop on time for inspection
Reason one: lack of refrigerant
A car air conditioner is same as a home air conditioner
Everyone needs to use coolant (freon in snow) to keep them cool. After refrigerant has been used up, this will result
The air conditioner loses its cooling effect
At this time, you can go to auto repair shop to check and top up refrigerant in time to ensure normal cooling of air conditioner
Reason 2: computer crash
Automotive air conditioner cooling system
Basic Components
Compressor, condenser, choke
and vaporizer
When communication fails in main equipment
Then air conditioner will lose its cooling capacity
Timely maintenance required
Cause 3: Faulty engine thermostat
Engine thermostat
Outlet of top of engine cooling water
this is a valve that controls flow path of coolant
When it fails
This will directly affect engine temperature
Engine temperature too low or too high
This will set off a series of chain reactions
The air conditioner will also have problems
If not processed in time
The whole engine can be recycled
