Commercial Mobile Air Conditioning Units: Condenser Coils

All commercial mobile air conditioning units have condenser coils that remove heat from the refrigerant. Without condenser coils, the unit will fail to cool the air. During hot summer days in Alberta, commercial condenser coils are working hard behind the scenes to keep workers comfortable and safe on the road and worksites. 

Keep reading to learn more about condenser coils, how they work, and common issues to look out for.

The role of condenser coils

In an air conditioning unit, the evaporator coil removes heat and moisture from indoor air. The condenser coil takes that heat and releases it outside. When air is blown over the coils, the refrigerant in the coils takes the heat from the air and transfers the air outdoors. Without the condenser coils, there is nowhere for the warm air to go, making it a crucial part of the AC unit. 

How a condenser coil works:

  • A fan blows air over the coils that are housed outside of the unit.
  • The chiller in the condenser coil cools the refrigerant liquid.
  • This liquid moves through the condenser tubing.
  • The liquid is converted into gas and distributed through the system.
  • The cool refrigerant liquid then goes back indoors to absorb more heat.

Common issues with condenser coils

When your condenser unit is malfunctioning, you will definitely notice when something is wrong. The condenser coils are such a vital part of the system that if an issue arises with coils, the AC unit itself will likely fail to cool the space. Some of the most common issues we see with commercial condenser coils are:

  • Dirty coils – As dirt builds up over time, it becomes harder for the coils to transfer heat which causes the air conditioning unit to deliver warm air into the space.
  • Damaged fan – If the fan becomes damaged, whether a blade is bent or there is a motor issue, it cannot blow the warm air out effectively.
  • Damaged fins – The fins that air blows through can become damaged and bent – one of the most common reasons for this is when something comes into contact with the condenser unit. Bent fins can block airflow.
  • A leak – A refrigerant leak is one of the most common issues that can cause an air conditioning unit to malfunction. A leak results in your system working much harder to cool the space.
