Inilah Fungsi Heater Pada Sistem AC dan Cara Kerjanya

The presence of the heater component in the AC system serves as a comfort keeper for users. As its name suggests, its function is to heat the air around it in the AC system. 

The location of the heater is between the cooling unit and the ducting or ventilation path. This way, the air that comes out of the AC system must pass through the heater before finally entering the room area. 

The heat source from the AC heater can come from the vehicle's engine or electricity, depending on the type of AC system used. To understand the function of the heater more completely, please see the explanation below. 

Function of the Heater in the AC System 

The presence of the heater in the AC system is indeed very important to provide comfort for someone when inside the car cabin or room. Especially if the temperature inside the room is low, it can make someone feel cold. 

Well, this is where the presence of the heater is quite important because it can warm the temperature in the room so that you still feel comfortable. In addition, its presence can also be used during the winter to reduce humidity.

To understand more clearly about the function of the heater in the AC system, please see its functions below. 

To Heat the Air

The most crucial function of the heater component is certainly to heat the air that comes out of the AC. Especially during winter or cold weather, the presence of the heater plays an important role. 

By heating the air around it, users can feel more comfortable when inside the room. Just imagine if the temperature is too low, it will make you feel cold. 

Improving Air Quality

Not only does it function as a room heater, but its presence can also improve the air quality in the room. It does this by killing bacteria and viruses that may be present in the air and can reduce unpleasant odors in the room. 

Helping to Reduce Humidity

The heater can also help to reduce humidity in a room by heating the incoming air. This method helps to reduce the risk of condensation or the growth of bacteria and mold. 

Preventing Windows from Fogging 

In cold weather or during the rainy season, the glass on the windows of houses or cars can fog up due to temperature differences inside and outside. However, when you turn on the heating system, it can prevent this fogging from occurring. 

How the Heater Works in the AC System

The way the heater works in the AC system actually depends on the type of heater used by the component. However, the heater found in car ACs usually operates on the principle of heating the air that can enter the room. 

For example, in the case of electric heaters, the electric heater in the car will convert electrical energy from the battery into heat. This electric heater is located in the AC unit and will be connected to its electrical system.
