Understanding HVAC Condensate Traps

- Опубликовано: 4 июн 2024
- Condensate traps exhibit many failure modes. Trap failures due to blockage, drying out, breakage, freeze-up and/or improper installation can compromise the seal against air ingestion through the condensate drain line. Traps with insufficient height between the inlet and outlet on draw-through systems can cause the drain to back-up when the fan is on, possibly causing drain pan overflow or water droplet carryover into the duct system. The resulting moist surfaces can become sources of biological contamination that can impact on indoor air quality. Seasonal variations, such as very dry or cold weather, may adversely affect trap operation and condensate removal.
The CostGard™ Condensate Drain Seal is inherently reliable. It is simple, has no moving parts, is self-cleaning, self-regulating and maintenance free. This reliability has been proven during more than twenty years of successful field operation. Tens of thousands are in operation in various types of facilities, indoors and outdoors, in every state in the United States plus Puerto Rico and the District of Columbia. Not one has become blocked or failed to operate properly.

Purchased: August 2023 - still works GREAT!I ruclips.net/user/postUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!
Very cool. Thanks for the upload.
Very well done. Great video!
Thank you
Awsome¿¿¿this boy know's what he's talking adout!!!.
Where can one find more information about how the CostGard operates? A video like this one explaining it with diagrams would be handy.

what would happen if a line was going from 2% grade to level? would the 2% slope still push the water through? or would it just sit there?
Slope to the main drain should be 1/8" per foot. CostGard uses the force of gravity to drain the water out of the system.
When blower motor set to high speed all the water in the trap will be suck into the unit and water never came out (negative pressure inside of the trap). This is a very stupid design. I have seen a lot issues on commercial units. Why don't put the fan behind the coil to blow the air through the coil? This way water will be blown out.
Most HVAC units are draw-through systems. Draw-through units create an air flow that allow higher cooling efficiency and a smaller cabinet footprint, which minimizes manufacturing and installation cost/expense. Blow-through HVAC condensate drains require a drain seal as well. Conventional traps on both blow-through and draw-through systems are prone to failures, which is why we have designed the CostGard Condensate Drain Seal for Blow-through and Draw-through HVAC systems.

How to calculate U-Loop length to maintain liquid head more than blower negative pressure head...
@@dixitpatel2873it's easy to calculate the drain size.
I found out that if your A-coil is down stream of the fan it is under pressure and you do NOT need a trap. If your A-coil is before the fan it is under a vacuum and you DO need a trap. In most home units are under pressure, NO trap needed. So look at your furnace, you probably do NOT need a trap. Don't waste your money and time if you don't need it.
Mine is def under pressure and my coil is before the fan
@@ex7229 ..when viewing airflow.....if your coil is "before" the fan ( meaning, upstream of the fan closer to the air i let of the air handler box), then there is no way your coil is under pressure. Like a cannister vacuum cleaner, the motor being downstream ( airflow direction), means the blower/motor is "sucking" air across the evaporator coil....not blowing it over the coil. If it's sucking the air over the coil....the coil is operating at a slight negative pressure.
It’s still good practice to install a trap, because you have a pretty good air leak if you don’t. Probably wouldn’t pass inspection without it.
