Ford A/C Specificationsby Alan Faeorin-Cruich
Since its invention in the 1940s, air conditioning has changed considerably. Now, air conditioning systems are computer controlled, giving the driver unprecedented control over the level of airflow and temperature. The three main components in any air conditioning system are the compressor, the evaporator and the receiver dryer. These three components work in tandem to cool incoming air and filter it into the car. Ford is not alone in using air conditioning in its automobiles, with most of its models coming with air conditioning as standard.
Manual control air conditioning is the standard specification given to most Ford cars. Models such as the Focus come with manual control air conditioning, with the option to upgrade for an additional cost. Manual air conditioning systems require the driver to manually turn them on. A button or a dial on the dashboard usually controls this. The driver can then select the level of blower by turning the fan level up or down. The restriction on a manual system is that the driver has no control over the temperature, having to feel when it is just right. The system is also unable to maintain a pre-programmed ambient temperature and will often require adjusting manually.
Automatic Temperature Control
Using a complicated array of both internal and external sensor, automatic temperature control calculates the current temperature and how to either raise or lower the ambient temperature to the preselected level. The automatic temperature control works with both the heater and air conditioning to maintain the appropriate temperature and prevent humidity levels within the car from causing the windows to fog over. The systems come in two varieties, semi and fully automatic. A semi-automatic system will maintain the temperature set by the driver, while a full-automatic system will do this and also operate other devices such as defrosters, heated seats and more.
Dual Electronic Automatic Temperature Control
DEATC, or Dual Electronic Automatic Temperature Control, is a system that is available in several newer Ford models, often as an optional extra. The system works as an automatic temperature control system, which allows users to select the temperature desired, and the system using advanced sensors throughout the vehicle will ensure that temperature is maintained. Unlike normal automatic temperature control systems, however, the DEATC is capable of maintaining two separate temperature regions, usually the left and right of the car. Other manufacturers use this system but call it climate control.
