What is climate control in a car and how does this system work

In the reviews of many cars, you can read that they are equipped with a climate control system. What is this system and what function does it perform?

Climate control is called the interior heater, air conditioner, fan, filters and various sensors combined into one system, which are located in different parts of the cabin. Climate control is regulated by electronic sensors, which create optimal conditions for the driver and passengers.

Climate control allows not only to maintain the temperature at the desired level, but also to do it zonal, that is, creating optimal conditions for each seat in the cabin, respectively, climate control systems are:

• single zone;
• two-zone;
• three-zone;
• four-zone.

Climate control consists of a climate control system (air conditioner, heating radiator, fan, receiver and condenser) and a control system.

Control over the temperature and condition of the air in the cabin is carried out using input sensors that control:

• air temperature outside the car;
• the level of solar radiation;
• evaporator temperature;
• air conditioning system pressure.

The damper potentiometers regulate the angle and direction of the air flow. The number of sensors increases depending on the number of climate zones in the vehicle.

All data from the sensors is sent to the electronic control unit, which processes and, depending on the entered program, regulates the operation of the air conditioning system, lowering and increasing the temperature or directing air flows in the right direction.

All climate control programs are entered manually or pre-installed initially. The optimal temperature conditions for the driver and passengers are in the range of 16-30 degrees Celsius. To save electricity, the air conditioner pumps the desired temperature and temporarily turns off until the sensors detect a decrease in the set level. The desired air temperature is obtained by mixing the flows coming from the outside and warm air, which is heated by the coolant in the stove radiator.

It is worth noting that climate control significantly affects energy consumption and fuel consumption.
