The condensate on the evaporator coil comes from the humidity in the air that is drawn into the HVAC system. As warm, moist air passes over the cold evaporator coil, the temperature of the air drops, causing the moisture to condense into water droplets. This process is similar to how dew forms on grass in the morning. The collected condensate is then typically drained away through a condensate drain line.

Where does the condensate come from that forms on the evaporator?

The condensate that forms on the evaporator comes from the moisture in the air. As warm, humid air passes over the cold evaporator coils, the temperature drops, causing the water vapor in the air to cool and condense into liquid water. This process occurs because the evaporator's low temperature creates a surface that is cooler than the dew point of the surrounding air. The resulting condensate is then typically drained away through a designated drainage system.


What does the term starved evaporator mean?

A starved evaporator refers to a condition in a refrigeration or air conditioning system where the evaporator coil does not receive enough refrigerant to absorb the required heat. This can lead to insufficient cooling, reduced efficiency, and potential damage to the compressor. Symptoms of a starved evaporator include frost buildup on the coil and a decrease in cooling performance. Proper refrigerant levels and system maintenance are essential to prevent this condition.


What is the proper way to run a condensate drain with a trap Does it need a vent?

The condensate drain on the a-coil should have a trap and the trap should be vented for proper operation . The vent should rise above the top edge of the drain pan in the unit. Their should be a capped clean out before the vent.

What is condensate blowoff?

Condensate blowoff is water that condenses on an evaporator coil, is blown off the coil, and then carried a short distance down the duct by the velocity of the air through the coil.


What are two methods used to evaporate condensate from the evaporator?

Where is the condensate drain line located in the air conditioning system?

The condensate drain line in an air conditioning system is typically located near the indoor evaporator coil. It is responsible for removing excess moisture that is produced during the cooling process.

Why is my air handler leaking water and how can I fix it?

Your air handler may be leaking water due to a clogged condensate drain line, a dirty air filter, or a frozen evaporator coil. To fix it, you can try cleaning the condensate drain line, replacing the air filter, and checking for any ice buildup on the evaporator coil. If the issue persists, it's best to contact a professional HVAC technician for further inspection and repair.


Why do Refrigerator evaporator coils leak?

The Refrigerator evaporator coil has many forces working upon it from a wide swing of temperature and pressure and vibrations that is caused. Then there is the ice that builds up on the coil between defrost cycles that produces some of the forces that are on the coil. To that add electrolyses of the different metal that are uses in the coil and the corrosive chemical bath that comes from the area and products being refrigerated. The refrigerator evaporator coil have a lot of silver soldered 90 degree union fitting that the forces work on. Than there is the design of the standard refrigerator evaporator coil. The coil sets in the drain pan and drips condensate into the drain pan. A long with the condensate comes some of the dirt and lent that collects on the evaporator fins and if not maintained it will plug the fins and than plug the drain pan. And fill the coil with condensate then more ice. When you really look at the refrigeration evaporation coil you wonder why they don't leak more. I am not even going to talk about the guys that defrost refrigeration evaporator coils with a ice picks.
