Why would the moisture condense in the ductwork which you would expect to be warmer than the introduced cold supply air? A number of things are going on here. When the air conditioning system is running, condensation could only occur on the OUTSIDE of the duct where it interfaces with warmer air. However, as the air passes through the cooling coil, it is usually dropped below its dew point, meaning that the air leaving the coil after being below dew point would theoretically be at 100% relative humidity. In reality, I have measured it at between 90 and 100 %. The only way that condensation can occur inside the duct would be if an inside duct were below the dew point of the saturated air in the duct, which is not usual. Super chilling the air and then reheating it is a form of dehumidification--just look at a stand-alone dehumidifier which does this exact thing. In most office buildings, the reheats are near the end of the duct runs so that the air is reheated prior to being supplied to the building spaces. That means that the air inside the duct that has been chilled is still at or near saturation up to where it enters the reheat coil. Of course, I am assuming that they did not specially install reheat coils in the air handling unit. Therefore, the duct interior is still being exposed to saturated air. Additionally, since the supply air temperature had been decreased to super chill it, if any condensation was occurring on the duct exterior, it will increase or new sources of condensation could occur because the duct exterior is at a lower temperature than before. That being said, I am not convinced that mold grows in ductwork during active cooling--that is, when air is moving through the ducts. Mold does not like to grow in moving air. In fact, studies have shown increased mold counts when systems come out of set-back or when they cycle on after sitting idle for a time for other reasons. The conclusion is that the saturated air sitting in the duct after the system goes into set-back or when it is not operating between cooling cycles (fan switch set to AUTO) supplies ample moisture for mold growth inside the ducts. Ducts that are in warm ceiling spaces or that are run above roofs would allow air temperature inside the ducts to warm rapidly, providing a nice warm moist atmosphere that is conducive to mold growth. In this discussion, I am assuming that the ducts are lined, have a debris layer and are otherwise supplying the food and spores needed for mold growth. The bottomline to all of this discussion is that, well, maybe they fixed the problem. It all just depends on those damn factors. ****************************************************** If what is written looks too stupid to be written by me, I disclaim it.

Guest guest Posted July 4, 2007 Report Share Posted July 4, 2007 Alice Older models of air conditioners used to remove a considerable amount of moisture from the air flow; the real need for comfort. Newer, energy-efficient models are allowed to remove almost no moisture, but just cool the air. As a result there are many more buildings at risk of severe indoor humidity problems indoors; then mold problems. Too bad that those who revised the standard on energy efficiency HVAC components do not read, then digest and understand, the ASHRAE and international publications on human comfort. Comfort comes more from reduced indoor RH than lower temperatures (reductions in both is a neat combination). Rather than reheat the supposed experts should have added dehumidification, improving comfort and reducing mold growth at a minimum energy cost. Not asking the correct questions, nor understanding what really matters, can result in some pretty bad decisions; air conditioners that remove little moisture are a very bad reality. Jim H. White System Science Consulting humidity I was at building in New York that claimed to have had indoor air at 100 per cent humidity in the summer, but has since solved the problem. It was explained to me as this:"In the past there was condensation in the ductwork due to air conditioning in the summer. This made mold grow. This was solved by using the reheat units, which dried out the air."This is a central air system with chillers on roof top and local reheats.I understand how supercooling the air in the summer and then reheating it would make it drier, but wouldnt the air conditioning alone remove a lot of the moisture? Why would the moisture condense in the ductwork which you would expect to be warmer than the introduced cold supply air?I'd be grateful if someone would help me make sense of this.

Guest guest Posted July 4, 2007 Report Share Posted July 4, 2007 , I liked your post but I would make one correction to your following statement: " The conclusion is that the saturated air sitting in the duct after the system goes into set-back or when it is not operating between cooling cycles (fan switch set to AUTO) supplies ample moisture for mold growth inside the ducts. Ducts that are in warm ceiling spaces or that are run above roofs would allow air temperature inside the ducts to warm rapidly, providing a nice warm moist atmosphere that is conducive to mold growth. " If the air in the duct right at shutdown is at 95% RH and let's say 55 degrees F, the air in the duct will start to pick up heat. It will eventually warm up to the temperature around the duct, let's say 75 degrees F. The rise in temperature will cause the RH to drop to 56%. This is well below the level where mold could grow. As Jim White said in a post yesterday, it's the RH not the humidity ratio that determines water activity (that determines growth). Someone may want to check my psychrometric calculation. I'm at home and I needed to rely on an online calculator: http://www.linric.com/webpsy.htm Besides that one point, I thought your post was right on. Most people don't realize that the RH at the coils is 100%! And Alice, the only way moisture would condense IN the ductwork is if: 1. the ductwork is colder than the coils 2. humid air is entering the duct (e.g. via some bypass of the coils) Ian Cull, PE, CIEC Indoor Sciences, Inc. > > >I was at building in New York that claimed to have had indoor air at > >100 per cent humidity in the summer, but has since solved the > >problem.

Guest guest Posted July 5, 2007 Report Share Posted July 5, 2007 Jim I have gone from a climate where it was impossible to oversize a residential air condtioner to the point of driving up RH, to a climate where my ambient dewpoint is equal to a nice summer day dry bulb where I grew up. The new air conditioners are more energy efficient and they do run at a warmer evporating temperature than the old equipment did.So perhaps they put 20% of their power into dehumdifying and the old systems put perhaps 30% of their cooling power into dehumidifying. Install them improperly, run the airflow too high, and you can further reduce how much moisture is removed. I think a blanket statement that it is all the fault of the air conditioner and the regulations forcing them to be more efficient is harsh. The old systems were just better able to compensate for other problems, mainly uncontrolled infiltration of humid air and oversizing. Blaming it on the regulations is the same as saying Building Codes mandating tight houses in Canada are to blame for windows condensating in the winter time. When I first relocated, I was of that opinion that energy efficient air conditioning was the culprit, but what I have truly learned is that if you properly control how air moves in/out of a structure, you can properly control humidity. This will apply anywhere. Having systems on hand that respond to humidity can be an absolute must due to the nature of some cooling loads and in other cases it is just good insurance. In a year round cooling environment such as the Caribbean, most homes and office buildings etc, could get by quite well with air conditioning alone. Loads with a high occupant density and in particular an active occupant density such as a night club or a Pentacostal Church will be overwhelmed with the moisture in the ventilation air and from the latent load that is created internally. Systems like this hit an impossible process meaning a cooling coil alone cannot supply air at both the correct temperature and the correct level of moisture. There is no Apparatus Dewpoint that will work. You can provide air at the correct temperature and have too much humidity in the space, or you can get supply air with low enough mositure content and end up with a space temperature that is too cold. This is when you absolutely need reheat. Reheat can be as economical hot gas reheat, which is standard in a mechanical dehumidifier. Regards Murray Woodgate P.Eng. Arista Engineering Co. Ltd.

Guest guest Posted July 5, 2007 Report Share Posted July 5, 2007 Fan switch in Auto will lower the RH in the space but you would have some standing water in a drain pan. A four ton system could have perhaps a half pound of water still on the fins of the coil when a cooling call ended, and a horizontal air handler could have that much moiture still in the drain pan. A drain pan with a drain on the bottom rather than the side of the pan would make a difference. Running that fan constantly could re-evaporate upwards to a pound of moisture in perhaps 10 minutes and elevate the RH of the space. Leaky return ducts passing through unconditioned spaces or a fresh air intake that does not close off could bring in humid air that would sweat on a cool duct surface with the fan running constantly. Perhaps after the coil dried out this moisture would re-evaporate also. But the constant fan can still be a humidity pump. Auto fan vs constant fan is six of one half a dozen of another in some peoples' eyes. In a humid climate I would take Auto Fan everytime and enjoy RH 5 to 10% lower in the space. > > > > >I was at building in New York that claimed to have had indoor air > at > > >100 per cent humidity in the summer, but has since solved the > > >problem.

Guest guest Posted July 6, 2007 Report Share Posted July 6, 2007 Thank you In Canada, new construction homes have been quite tight for at least 20 years. The ceilings in particular have the sealed poly at the underside of the trusses. It follows the vapour barrier on the warm side of the insulation rule. It gets a little challenging in a year round humid climate, with a vented attic as it is hard to seal 'on the warmside of the insualtion' as it is on top of the insualtion now, and the pesky roof trusses do not want to cooperate. The vapour bariers are to stop moisture but they effectively stop air moving through the ceiling plane as well. I have a simple sealed attic in the tropics. Recently I was logging how mositure would build up in my home with the air conditioning shut off. The outdoor humidity is pretty constant. I am presently looking at four hours of readings taken every 5 minutes and using the changing amount of moisture in my home as a tracer for how much air leaks. I think I am going to end up being very low, less than 0.1 ACH from infiltration. I am also holding a solid 40% RH humidity, and it has to be due to the low infiltration that this is possible, given my climate. If I can only get a tropical system with a foot of rain to pass over I could wrap up my infiltration test :-) When the air conditioner runs, it changes the air at about 0.3 ACH and does so by pressurizing the building. When the AC runs, dry air is trying to escape my home. The next step for my on going experiment would be to montior CO2 levels with my intermittent positive pressure scheme. > >> > > >> > Alice > >> > Older models of air conditioners used to remove a considerable > > amount of moisture from the air flow; the real need for comfort. > > Newer, energy-efficient models are allowed to remove almost no > > moisture, but just cool the air.

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 i live here in the philippines, tropical weather. sometimes it gets hot in the afternoons and a bit chilly in the evening. i have attacks when there is sudden change in temperature.

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 I had the same question, as I am in Raliegh, NC and have had a hard time breathing myself this week, the temperatures have sored into the 100's and the humidty is high this is my first year with asthma. I have been getting very lightheaded and have been having difficulty breathing. I justed moved from NJ and didn't realize the impact, I also have had a lot of issues with second hand cigerrette smoke. I too struggle on a daily basis, as I use to be able to run and work out, I am learning my limitations, but get very frustrated. humidity I am very sad today because I had a day trip planned and I had tocancel.

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 Thank you for all your comments....i feel so alone sometimes. My dr likes to amuse me by asking me to come to her daughters ball games...even she doesn't understand i can't do this weather. I live in Illinois and the humidity is 94 percent. Where is the best place to live? I have had three pred shots already this year and have gained weight so i don't want another shot yet. I have two different nebulizer meds and a rescue inhaler. > > i live here in the philippines, tropical weather. > & nbsp; > sometimes it gets hot in the afternoons and a bit chilly in the evening. & nbsp; i have attacks when there is sudden change in temperature. & nbsp; Air-con rooms triggers it more. & nbsp; > & nbsp; > newly cut grass is a real threat to me. & nbsp; specially when it just rained on a mowed lawn. > Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 Do you only get steroid shots when you have a flare or are you taking them daily? It seems that would not help much, just one shot, I know the shot did nothing for me until I was put on a daily dose for a few weeks. Of course I just got off three days of IV solumederol.which works great! Too bad its so hard on the body in general. Re: humidityThank you for all your comments....i feel so alone sometimes.

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 I live in Central California, armpit of the state....desert. It can get up to 115 degrees here and we usually hit at least 103 most of the summer months...still in shorts on Thanksgiving. But I have NEVER in my life felt what I did when I got off a plane 7 years ago outside Washington DC heading to Lancaster PA in late August. What IS that?? I couldn't wait to leave here because it had been in the high 90's/low 100's for several weeks. I was in PA for 2 weeks and kissed the ground when I returned to sunny CA!!! We never have humidity here. It is a very dry heat. It isn't fun but I now know there is truly worse. If I can stay in an air conditioned environment I do ok but a lot of people use swamp coolers here when it's below 100 and that sometimes bothers me.

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 OMG when I visited my Uncle in Colorado about 6 years ago they were complaining how HOT it was, I was like, this is NOT hot, this is nice, add humidity to it and it's hot! The humidity is what get's me. We just came out of church where it was AC and when that heat hit us all, everyone was like UHH, no more outside time for me today!

Guest guest Posted June 7, 2008 Report Share Posted June 7, 2008 What exactly does a dehumidifier do? I have an Ionic air cleaner in my room and it does help. I have one in the daycare downstairs and one in the living area, I rarely have to dust. However I need to buy a new vacuum. I go through more vacuums than appliances LOL Terry I know God will not give me anything I can't handle.
