Air Conditioning and Climate Control

The aim of Climate Control is to maintain a constant temperature within the vehicle cabin.
It is controlled by the occupants and sometimes can be set independently for driver and passenger.

The general principle is to set the temperature for your personal comfort and a highly sophisticated computer and sensor system then monitors the internal and external temperatures to determine if the air needs cooling or heating to reach and maintain that temperature regardless of ambient conditions.
The engine generates sufficient heat for most purposes and a separate air-conditioning or refrigeration unit controls cooling and removal of condensation.
The whole system is designed to achieve the desired internal preset temperature as quickly as possible and then to maintain that temperature irrespective of the external ambient conditions.

Air Con Units tested and Inspected for

• System pressure check

• Recharge and purify refrigeration gases

• Inspect condenser for corrosion, physical damage and leaks

• Heater controls

Air Conditioning and Climate Control - Refrigeration Unit

It uses the evaporation of a refrigerant, to provide cooling.
The mechanics of an air-conditioning system are the same as your home refrigerator.

1. The compressor applies high pressure to a low boiling liquid (refrigerant), causing it to become a hot, high-pressure gas.
2. This hot gas runs through a set of coils to remove its heat, and condense into a liquid.
3. The refrigerant liquid passes through an expansion valve, and evaporates rapidly to become a very cold, low-pressure gas.
4. The cold gas runs through a second set of coils that allow the gas to absorb heat from the air and in the process cool down the air inside the vehicle.

The warm refrigerant gas is then compressed and the process continues.
Mixed in with the refrigerant is a small amount of a lightweight oil to lubricate the compressor.

Gradually the gas leaks from the system and it becomes less and less effective.
We can recharge the refrigeration system and bring it back to full efficiency. The Climate control unit and sensors can also be checked to ensure the system is functioning correctly.
