Application Considerations

Condensate Traps

When designing a condensate trap for the water-source system, it’s important to consider the unit’s draw through design.

Under normal conditions, condensate runs down the coil fins and drips into a condensate pan. In situations where no trap is installed, the water level that would be maintained in the trap to create a seal, backflows through the drainline into the unit. Because the fan pulls air through the air-torefrigerant heat-exchanger, this incoming air stream could launch water droplets, forming at the base of the coil, into the air.

Air flowing through the coil can then spray condensate into the fan intake, with the possi- bility of propelling moisture into other parts of

the mechanical system. This aerosol

mist can be carried through the ducts and into the conditioned air space.

Another problem with air backflow, is the source of that air. Drain lines typically flow into waste or sewage lines, giving the potential to introduce methane and other contaminants from the drain system into the airstream.

In a properly trapped system, when conden- sate forms during normal operation, the water level in the trap rises until there is a constant outflow. (See Figure 31, for the appropriate dimensions required in designing a negative pressure system.)
