Condensate Removal from HVAC Equipment - Mechanical Specification for HVAC Air-Trap™

The installer of the HVAC cooling (or Energy Recovery) equipment shall be responsible for the removal of condensate,

and other possible sources of water formation, from the unit and the delivery of the water to an approved drainage

system as determined by local codes or owner’s preferences, such as gray water storage or storm water drainage

system. The external drain lines shall be connected to the unit by means of unit manufacturer supplied standard male

pipe connections stubbed external to the unit, near the base. The drain line shall be sloped downward at a minimum of

1/8 inch per running foot in the direction of water flow away from the unit.

To prevent air from entering or leaving the Air Handling Unit, an “Air Trap” shall be placed within the water drain line

that always prevents air flow through the trap but allows water to exit the unit and flow to the drainage system.

Whether positive plenum pressure (fan blowing through cooling coil) or negative plenum pressure (fan drawing through

cooling coil) an HVAC Air-Trap shall be installed within the drain line as near to the unit drain connection as is

practicable.

The trap shall not be of the type typically designated as a P-Trap. The trap shall be an HVAC Air-Trap as manufactured in

the USA by Des Champs Technologies and available at any local HVAC or plumbing wholesaler. The trap shall:

a) Prevent any water from remaining in the drain line when there is no condensate being produced

b) Prevent the possibility of broken pipes because of freezing

c) Not require filling with water in spring or after extended period of no condensate formation

d) Designed to not allow standing water within trap

e) Prevent sludge buildup within the trap

f) Prevent the geyser effect with “dry trap” and negative plenum pressure

g) Not allow blowout with “dry trap” and positive plenum pressure

h) have a total height equal to the maximum water pressure in inches WC. With negative pressure plenum, the

HVAC Air-Trap requires less than ½ the height required for P-Trap installation

i) Meet standard building code requirements

j) Be predesigned and site proven to eliminate field guesswork

Air entering or leaving an HVAC unit via the condensate drain line manifests itself as an energy loss and a reduction of

indoor air quality, the reason being that the replacement air must be filtered and conditioned. In addition, air drawn

into a unit (which occurs often with a dry P-Trap) usually originates at undesirable locations such as gray water storage

tanks or near sewer vents. As a result, the condensate line trap shall be an HVAC Air-Trap by Des Champs Technologies,

which never experiences “dry-out” and never allows air to flow through the drain line.

The drain line shall, in addition to being properly sloped away from the unit, may require inclusion of a vent pipe. If

required, the vent should be installed as close to the exit of the Air-Trap as possible. The purpose of the vent is to

prevent a vacuum from developing at exit of trap which could result in a trap malfunction. All condensate piping shall

be supported to maintain a straight alignment, a uniform slope, and intervals required by the Uniform Plumbing Code.

Allow for thermal expansion and movement in all plastic piping installations using approved methods. Support, but do

not rigidly restrain, piping at branches or changes of direction. Do not anchor rigidly in walls. Holes through framing

members shall be adequately sized to allow free movement.

For HVAC Unit ______ the condensate drain line shall be ___ inch diameter schedule 40 PVC and the condensate trap

shall be a Des Champs HVAC Air-Trap, Model ______________________, capable of accommodating _________ GPH of

condensate at a plenum pressure of __________inches WC positive⌂ negative⌂. Refer to HVAC Air-Trap Manufacturer

ELIMINATES NEED TO CONSTANTLY MONITOR DRAIN TRAPSFOR DRY OUT, SLUDGE BUILDUP, AND FREEZING

P trap, the Standard Condensate Trap of the HVAC Industry

When it comes to mouse traps, it is difficult to find a newfangled trap that works better thanthe standard spring loaded Victor type that has been around for over a hundred years.Likewise is the case with the “P” trap or P trap, the industry standard for removing condensateor water from an air handling unit (AHU) while simultaneously preventing dilution ofconditioned air by outdoor air. The principal reason the P trap has had such staying power is itsfirst cost and simplicity. In many parts of the world, if properly designed, it does its job okay.However, in areas where freezing weather occurs, there are four distinct seasons, or where hotand dry as well as hot and humid conditions exist, the P trap has negative issues. Figure 1shows typical P trap design guidelines.

Figure 1a Negative Plenum Pressure Figure 1b Positive Plenum Pressure

The most common problem with the standard trap is when there is little or no water in thetrap. This occurs when the P trap never had water fill, operated for extended periods with no

water generated within the AHU, or never filled with water even during condensate productionbecause:

a) For negative pressure, a geyser effect as the condensate attempts to exit through adrain opening having high velocity incoming air, causing insulation, fans, motors,etc. to get wet

b) For positive pressure, the velocity of the air escaping through a dried out trap issufficiently high that it carries the water that is condensing with it as the air exits thetrap.

c) Proper design for the height of a standard trap is to have a minimum between thebottom of the trap and the bottom of the horizontal drainpipe exiting the trap of 2times the maximum pressure in inches of WC expected within the AHU plenumwhere the drain is located. Because of height restrictions, many trap designs do notmeet these dimensional requirements, which could lead to dry out and air by pass(the greater the depth of a P Trap the less chance of it drying out).

d) A syphoning effect caused by washing the drain pan or any surge of water throughthe P trap could lead to dry out and a loss of the air seal.

Second on the list of P trap problems is freezing and breaking. At the end of the coolingseason, water fills the trap to near the horizontal trap exit pipe, leaving more than enoughwater within the trap to carry over to the freezing season. Unless the trap is heat traced orfilled with some form of antifreeze, the trap will freeze and possibly break. Freezing is generallyconsidered to be the number one trap problem because the results are readily apparent andare costly whereas dry out is not readily apparent but can be more costly because of wastedenergy. In addition, broken traps caused by freezing, if not immediately repaired, lead to dryout which can persist for years.

The operation of a P trap, with continuous filling and drying, leads to sludge or debris collectingin the bottom. Without proper trap maintenance, the drain pan could overflow.

The height required for a P trap is the last issue discussed. In an AHU, the condensate drainpan normally rests on the unit floor. The drain line connection is at the lowest point of thesloped pan. The AHU floor is on a frame that varies in height from four inches (lightcommercial) to eight or more inches (commercial). For commercial HVAC equipment, typicalpressures within the AHU range from minus 6 inches to plus 6 inches WC. If a unit were to beoperating at minus 6 inches WC maximum negative plenum pressure then the trap height, perthe guidelines shown in Figure 1a, requires 7 + 3½ + 1½ + 1 inches of height from under thefloor or about 13 inches below the floor level. With a unit frame height of 8 inches, a curb isrequired under the unit in order to accommodate a properly designed P trap... an expensiveproposition.

The Des Champs Technologies HVAC Air-Trap

Des Champs offers a commercial trap designed for negative plenum pressure and one designedfor positive plenum pressure applications for pressures up to 12 inches WC and aresidential/light commercial capable of operating up to a pressure of 3 inches WC, operatingwith either positive or negative pressure. The majority of HVAC trap applications are on drawthrough AHUs, where the cooling coil is in a negative pressure plenum. Draw through designsgenerally result in less overall pressure drop through the AHU because of more evenlydistributed airflow through the components, such as dampers, filters, coils, and heaters. Thereare also persuasive reasons for specifying a blow through AHU, especially when gas heat isinvolved.

The Des Champs N Series HVAC Air-Trap

Figure 2 illustrates the height saving of the N Series Air-Trap when compared to a standard Ptrap for a typical installation. The illustration is for a 2 inch negative pressure system but theratio of 4+ to 2 (P trap to N Series Air-Trap) holds for any negative pressure, i.e., if thenegative pressure is 4 inches WC then the P trap requires approximately 9 inches of heightwhereas the N Series Air-Trap requires only 4½ inches of height. This reduced heightrequirement could result in considerable cost savings during installation.

Shown in Figure 3 is a cutaway view of the Des Champs N Series Air-Trap. The hollow balltravels on horizontal rails and with the fan on and no condensate flowing, the ball valve snugsagainst the left circular entrance port/seat, resulting in essentially no air drawn through thetrap and into the AHU. Once condensate flows, the ball stays against the seat until the waterlevel in the vertical standpipe reaches a height H, in inches, equal to the plenum negativepressure in inches WC. When the water column reaches height H, the water pressure on theball equals the negative air pressure holding the ball against the seat and the ball moves awayfrom the seat, allowing water to flow. When condensate ceases to form, then the ball valvereturns to the seat and prevents air from flowing into the unit.

assurance that no water will remain in the trap or incoming standpipe when freeze time comes.The N Series Air-Trap operates at essentially any negative pressure up to the distance, ininches, between top of the water level in the plenum and the centerline of the horizontal NSeries Air-Trap. Maximum water flow rate is greater than two GPM, which is equivalent toover 80 tons of latent cooling.

The N Series Air-Trap has sufficient merits for consideration on all negative pressureplenums. However, there are many instances when it is essential to consider their use. Forinstance, a contractor informed an AHU manufacturer that a back charge of $50,000 is eminentbecause late delivery resulted in having to remove building walls and putting units on curbs, notincluded in original specification. The reduced height of the N Series Air-Trap removed therequirement for curbs and eliminated the back charge.

The Des Champs P Series HVAC Air-Trap

Shown in Figure 5 is a cutaway view of the Des Champs P Series Air-Trap, used for removingcondensate from plenums operating under positive pressure.Whereas the N Series Air-Trap must be installed and operate in ahorizontal position, the P Series Air-Trap, because its operationdepends upon buoyancy to properly function, must be operatedvertically. With no production of condensate within the AHU thepositive pressure that exists within the plenum, containing the drainline, forces the capsule (or spherocylinder), shown in red, downwardonto the valve seat. With the production of water within theplenum, the capsule rises from the seat when the net buoyancy forceupward equals or exceeds the net downward force created by airpressure.

Figure 5 Positive Pressure Des Champs P Series Air-Trap

The P Series Air-Trap, in addition to installing vertically, has additional factors that areimportant to understand and consider during its design into the drainage system. These factorsarise from the fact that the capsule rises and falls depending upon the pressure differentialbetween the air pressure entering the trap at the top and the air pressure leaving the trap plus

the buoyancy of the capsule when water is present. The air pressure at the top is equal to theplenum pressure, and at the bottom, it is normally ambient pressure.

However, if the piping system leaving the trap is long, has sags, or is too small in diameter toproperly accommodate the water flow, then a syphoning effect could develop at the bottom ofthe trap, creating a negative pressure sucking the capsule downward. This, in turn, could causethe trap to malfunction. To prevent a negative syphoning pressure, install a vent pipe directlybelow the exit of the trap as shown in Figure 6.

Figure 6 Positive Pressure HVAC Air-Trap undergoing tests at the Des Champs TechnologiesLas Vegas, NV test facility. Testing videos showing the operation of the trap are viewable atwww.deschampstechnologies.com, then go to P Series and then to P-Series YouTube Presentation

Use of the P Series Air-Trap is to drain water from HVAC plenums that are operating at apositive pressure created by a blow through fan arrangement within the AHU design. There aremany reasons to design an AHU for a blow through arrangement and a few are:

a) As an aid in preventing outside air from entering the AHU

b) To reduce the noise level within the supply air plenumc) To accommodate a more compact designd) Cool fan and motor heat prior to air delivery to conditioned spacee) For energy recovery units, to prevent exhaust air leakage into supply airstreamf) When gas heat is furnished as a component of the AHU.

An example for application of the P Series Air-Trap is for AHUs used to remove heat fromdata centers. This type of AHU could incorporate both an indirect evaporative cooler and acomplementary cooling coil. Both cooling components can produce condensate, so there aretypically trap requirements in three or four separate plenum compartments, including theblow through fan compartment. Blow through is desirable to keep the unit under positivepressure to prevent leakage of outdoor air into the highly filtered and humidity controlledrecirculating air and to enable the cooling system to remove most of the heat generated byfans, motors, and compressors before delivering the cooled air to space. There is also lessnoise in the supply duct.

For Data Center cooling, recirculating, cooling air typically returns to the AHU at around 95 Fand cools to 75 F. Seldom, under these conditions, does condensing occur. Consequently, thestandard P traps require frequent filling, a costly maintenance issue considering there could beupwards of fifty and, in some cases, as many as a thousand traps to fill. If they go dry, thepressurized recirculating air leaks to outside of the conditioned space, resulting in the facility’smake up air system becoming inadequate. Freezing could also be an issue with P traps.

Data center owners complained about the maintenance issues associated with using standardP traps on their AHU cooling units. Specifying engineers responded by specifying theDes Champs P Series Air-Trap, which does not require water to prevent airflow out of theAHU and consequently eliminates the need for routinely filling the traps with water. Inaddition, during the cold months, when the cooling coil is not condensing the Air-Trap is dry.If, for some reason, water is flowing from the unit during freezing temperatures, and the trapsees below freezing temperature, then the trap requires thermal protection.

The N and P Series of Air-Traps are available in ¾, 1, 1 ¼, and, 1½ inch PVC schedule 40 slipconnections, and are directed towards the commercial market.

The Des Champs RLC Series HVAC Air-Trap

The RLC Series is directed towards the residential and light commercial markets and is limitedto a maximum of 3 inches WC pressure differential whereas the N and P Series are limited to amaximum of 12 inches WC. Also, the RLC Series is available in two connection sizes, 3/4 inchslip (on inside of connection pipe) and a 1 inch fitting (on the outside of connection pipe).However, with standard schedule 40 PVC bushings, available at any big box hardware orplumbing wholesale store, PVC pipe from ½ to 2 inches can be attached to the RLC. Also, asshown in Figure 7, the Series RLC Air-Trap may be used for either negative pressure orpositive pressure applications. By installing horizontally it becomes a negative pressure trapand by installing in a vertical position it becomes a positive pressure trap. The operatingprinciples and advantages are similar to the P and N Series as previously presented.

Figure 7 Layout of the Series RLC Air-Trap

Summary

The Des Champs N and P Air-Trap designs are patented and the RLC has patents pending.They have tremendous benefits if properly installed per the manufacturer’s instructions, whichare simple and straightforward. They are:

1) For negative pressure drain pan, install trap horizontally with water flow in direction ofarrow with arrow on the top of the trap after installation.

2) For Positive Series:i. Install vertically with end marked TOP on top.ii. If a long length of drain pipe and/or a small drain pipe, less than 1¼ inch

diameter, then a vertical, vent tube is required to be installed as near tothe exit of the trap as possible, as shown in Fig 6.

iii. Care must be taken when cleaning or flushing the drain pan1. The fans creating the pressure at the drain pan must be in off

position.2. Either a screen over the drain inlet or a Union Strainer, placed in

the line, between the drain pan and the trap, is necessary toprevent the solids and debris from clogging the trap.

If the water flow rate of the cleaning system is greater than the water flow capacity of the trapthen the trap clean out plug will have to be removed prior to cleaning. Caution is necessary toprevent the cleaning water from overflowing the drain pan.

Installation, Operation, and Maintenance Manual for

Des Champs Technologies Waterless Trap

HVAC Air-Trap™ P-SERIES

Positive Plenum Pressure

These instructions are a guide to the user of a P-SeriesAir-Trap during installation, commission into service,operation, or periodic maintenance.

Product Description

The P-SERIES Air-Trap allows water to drain fromHVAC equipment and simultaneously prevents air fromescaping from the equipment.

The P-SERIES Air-Trap does not require standingwater to prevent gas (typically air) from leaving theHVAC unit. With the occurrence of condensate, orother water sources within the unit, the water flows outof the HVAC unit but no gas escapes. When there isno production of condensate or water, there is no waterin the trap and there is no gas leaving through the trap.Install the P-SERIES Air-Trap in a vertical position.

Delivery CheckUpon receipt of the air-trap(s), inspect for damage thatmay have occurred during shipment and check toinsure delivered items match purchased items.

Resolving Shipping Damage

If damage or items are missing:1. Report all claims of shipping damage to the

delivering carrier (transporter) immediately, andschedule an inspection.

2. Make specific notations on the freight billconcerning the damage.

3. Keep damaged material in the same location asreceived. The receiver is responsible forproviding reasonable evidence that damagewas not incurred after delivery.

4. Photograph damage if possible.5. Do not move or discard damaged freight

packaging materials.

6. Notify the sales representative, or Des ChampsTechnologies, of the damage. Do not attemptto repair the unit without consulting the salesrepresentative or Des Champs Technologies.DES CHAMPS TECHNOLOGIES IS NOTRESPONSIBLE FOR SHIPPING DAMAGE.

Storage Considerations .

Store the Air-Trap in a protected area prior toinstallation. The warranty will not cover damage to the trap resulting from negligence.

Maintenance and Techniques for Cleaning the RLC Air-Trap

Preventative Maintenance In some operations, large particulate matter can move from the HVAC unit through the drain line and into the Air-Trap, causing a malfunction or failure. The best way to reduce maintenance is to install a strainer screen at the inlet to the drain line (Fig. 1) or a Des Champs Union-Strainer™ upstream of the Air-Trap, (See Fig. 5) to prevent miscellanious items like, rocks, screws, and nuts from ever getting into the trap. The Union-Strainer™ is also a convenient way to prevent unwanted creatures and objects from entering at the terminus of the drain line, like snakes, rats, lizards, insects, and plant growth. The water flow is in direction of arrow shown in Fig. 5, with the strainer cup oriented to capture debris within the cup.

There are several options for cleaning. Option 1 is to use the ½-inch threaded cleanout port in the trap housing. This will allow insertion of a water or air hose/syringe for washing or blowing away material that may be hampering operation of the trap. See Fig. 3.

Option 2 would be to isolate the Air-Trap using unions that allow Air-Trap removal for cleaning.

. Figure 5: In-line Union-Strainers. Install in the drain line upstream of the Air-Trap. This will aid in preventing debris from entering trap. The arrow shows the direction of water flow, into the strainer basket.
