Useful Facts:
- Vehicle air conditioning may deteriorate naturally by 10-15% per year
- Vehicle air conditioning has serviceable components requiring regular maintenance
- Moisture and contamination build up over time creating high pressure points and blockages
- Fuel consumption increases
- Expensive components wear prematurely
- Leaks, if ignored, allow moisture to penetrate vital components
Air conditioning should be:
- Used all year round
- Refreshed every two years
- Inspected immediately a fault arises
To produce Conditioned AIR, refrigerant has
to cycle in the following sequence:
- Starting at the Compressor,
where it is heated and pressurised, travelling then as a vapour
to the Condenser,
forward to a Receiver Drier*
where moisture and debris is removed. -->
- The refrigerant travels towards the back
of the engine where a valve drops the temperature and pressure
of the system, thus allowing cool refrigerant into the Evaporator,
situated right behind the Heater.
The cold Evaporator
draws heat from the heater, cools it (evaporates) and distributes
cold air through vents in the vehicle cabin.
--> --> --> --> returning by suction to the Compressor......
to begin again.
* All vehicles have a drier, although not necessarily in the same
location.
* System illustrated is for vehicles only.
 The air conditioning compressor is at the heart of all air conditioning systems. Like our own heart, it has to have the right food at the right time and in the right quantity to maintain peak performance. Likewise, it also needs regular exercise to remain healthly.
Regular servicing of the air conditioning system ensures that all the levels are as they should be.
Consider this...... the system deteriorates by 10-15% per year, after 3 years the the oils and refrigerant may have depleted by up to 50%. The heart is pumping twice as hard to keep up!
How long would you last...?!
