What is a condenser Fan?

A condenser Fan is a type of fan of the HVAC system, that is located near the condenser. It is specially designed to eliminate or remove heat from the refrigerant.  When you switch on the AC, refrigerant picks up heat from inside the room at the evaporator coil. Then it is travel to the condenser. Condenser is located outside your room or home. The condenser fan removes the heat from the room.

More Detail

It is exclusively used only for AC systems. It is responsible for producing cool air by expelling heat into the outdoor air. If it is not cared for or maintained properly, It will carry dirt, debris, and dust. It will wear and tear more frequently or faster. If this will happen, It will result in warm air, Poop airflow, and a suffocated indoor environment. If it is maintained properly, It consumes less energy. It will increase the life of the rest of the system too.

Hows it Works

A condenser is a Part of an HVAC system. It is a heat exchanger. It cools and condenses gas refrigerant into liquid form. After this, the refrigerant goes through the condenser coil and goes to the evaporator. At the evaporator, It turns into a gas once again and this process is repeated.

It is located near the top of the condensing unit. It is covered with a grill or guard to prevent debris and other objects.

Condenser Fan Material

Most HVAC systems use a fan that has blades. These blades are made up of plastic, metal, and aluminum. You can change these blades when the old ones are out of service. You can choose whatever material you like. These all materials are lightweight but their weight might increase with the size of the blades.

Its material depends on the type of environment in which you want to use it. Aluminum fans come in diameter from 2 inches to 48 inches.  The number of blades also varies. It comes in 3 blades to 10 blades.

Advantages of a condenser fan

  • These fans are cost-effective.
  • These are compact and occupy less space.
  • These are very easy to install and take less time for installation.
  • It maintains the temperature and humidity.
  • Its maintenance cost is low.
  • It prevents dust.
  • It is used universally. (Used in any environmental conditions)

The room goes too hot when AC is ON

Sometimes, You ON the AC but it is not producing cooling. It produces only hot air. This is a cristal clear indication that the fan is not in good condition.
