Prior to the introduction of climate control, vehicles had a basic heating/cooling system that merely threw either hot or cold air at you based on the vehicles occupants’ preferences.
Climate control is an advanced platform of vehicle air conditioning that allows the vehicles occupants to be seated in a pre-set temperature environment. A set temperature is selected and there after maintained by the vehicles climate control system, enabling occupants to enjoy a constant temperature controlled environment without having to make changes to the vehicles air conditioning settings throughout the duration of their journey.
The air conditioning unit situated within a vehicle is designed to extract heat from an area using a refrigeration cycle. In a vehicle, the air conditioners compressor is driven by an electric motor that’s purpose is to pump a refrigerant (cooling gas) around the evaporator coil which is the cooling compartment of the air conditioning unit. The same compressor also pumps refrigerant around the condensing coil which is the heating component of the air conditioning unit. The exact ratio of hot and cool air is then calculated by the vehicles climate control system and is pushed into the vehicles cabin by another electric motor. The desired cabin temperatures are controlled via buttons located in the vehicles dashboard or in some instances, on control buttons located on the vehicles steering wheel. The climate controlled air conditioning automatically adjusts the ratio of hot and cold air from the two compartments and this mixture is then fanned through the cabin to automatically maintain a constant temperature throughout the vehicles journey.
Various vehicles even feature dual or triple zone climate controlled air conditioning which gives the driver and passengers of the vehicle the ability to control the temperature in their own area of the cabin.
