Q:

What are the functions of condenser water pumps?

A:

Quick Answer

Condenser water pumps induce condensation in heating, ventilating and air conditioning, or HVAC, systems to remove excess heat from refrigerants and remove the heat outside. Also known as condensers and condensate pumps, these pumps act as heat exchangers for heating and cooling systems.

In air conditioning systems, there are typically three types of condensers:

  • Air-cooled condensers - This type of condenser removes the heat in the system by blowing the condenser coil with air.
  • Water-cooled condensers - This type of condenser removes the heat in the system through water poured over the condenser coil.
  • Evaporative condensers - This type of condenser forgoes the refrigerant and cools the system by allowing the water to evaporate outside of the system and into the air.

Most residential systems utilize air-cooled condensers, and many condensers are composed of the same parts, which include the coil, compressor, fan and controls. Coils are typically made of copper tubing that has aluminum fins, or all-aluminum tubing. To keep the system functioning efficiently, the coils should be kept as clean as possible.

The fan is extremely important in air-cooled systems as it circulates the air across the coil to remove the heat from the system. The compressor can fail or the efficiency of the system can be compromised if the airflow is blocked, so it is important to keep this area clear of debris and dirt.
