Air Conditioning Facts
The Vehicle Air Conditioning Cycle
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 cabin, cools it (evaporates) and distributes cold air through vents in the vehicle cabin. The surplus moisture is collected on a tray and let out through a drain tube. It is quite healthy for a pool of water to form on the floor when the vehicle is stopped
--> 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
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...?!
What you need to know…
Your Air Conditioning System is a sealed system requiring specialist maintenance
- The system is pressurised using a cooling gas just like a fridge
- Unlike a fridge up to 15% of cooling gas could be lost naturally every year due to engine vibration and the constant expansion and contraction of pipe joints
- A 3 year old system could be up to 50% inefficient
- Manufacturers recommend routine servicing
- This is quite usual at 2 year intervals or 30.000 miles
- Changing the desiccant pack is good practice at the same time
Condenser situated at the front of the radiator
Your system has expensive components, which require regular maintenance to prevent expensive repairs. The desiccant pack traps moisture and contamination. An inefficient system will use more fuel
- An effective well maintained Air Conditioning System will deliver Purified Air
- Reducing travel fatigue
- Aid demisting in cold and wet weather
- Stops pollens and other allergens entering your space
- Cuts down circulating pollutants
- Maintains a more comfortable travelling environment
- Use less fuel
The Evaporator.
Air Conditioned Air
Purified - Dehumidified - Bacteria Free
Let’s keep it that way - Breathe better Air
Tip… Run your air conditioning with some heat during the winter months This will keep the heart of the system pressurised aid demisting and will lubricate the seals which will help prevent the gas escaping.
