How does the air conditioning in a car work?
The air conditioning or A/C system in a vehicle works by manipulating refrigerant between a liquid and a gaseous state. To change the refrigerant between a liquid and a gaseous state the air conditioner controls pressure and temperature. This makes it able to absorb heat and humidity from the vehicle, allowing the system to give cool and dry air. Read more …
Providing safety and thermal comfort
An air conditioning system plays an important role in a vehicle. After safety considerations such as defogging and deicing the windows, the next most important function of the climate control system is to provide comfort to the occupant. This in turn also adds safety to the vehicle because thermal comfort affects driver alertness.
The focus should be on the comfort of the occupant and not on achieving a uniform thermal environment within the cabin, regardless of the number of occupants. An advanced climate control system might minimize radiant loads on the occupant, remove moisture from the occupant (such as from a ventilated seat), and include direct heating and cooling of the occupants.
Maintaining the air conditioning system
A properly functioning air conditioning system helps to keep you safe but also assists in improving the air quality in the vehicle by removing pollutants, bacteria and pollen from the air. However, over time, the quality and volume of the refrigerant gas in the vehicle’s air conditioning system will decrease, especially if the system is not used regularly, affecting performance. In addition leaks and bad odour may occur leading to performance loss and unpleasant and unhealthy air quality. Therefore it is recommended to maintain the air conditioning system in order to keep it clean, maintain a healthy and pleasant air quality and protect the system from malfunctioning.
