AC DRAIN LINE DIAGRAM WINDOWS
U values for roof, walls, windows as per the 2013 edition of ASHRAE 90.1 : Energy Standard for Buildings Except Low-Rise Residential Buildings. The i denti cal orientation of the building for all zones See results in the Table 2 :īuilding size = 10,000 square feet, Occupancy = 250 square feet /person, M iscellaneous load = 1 workstation/person Ventilation rate was calculated per Chapter 4 of 2015 I nternational M echanical C ode.
AC DRAIN LINE DIAGRAM SOFTWARE
A commercial – grade load calculation software to perform these calculations was used. To put this in perspective, condensate volume generated for an identical building with identical occupancy and orientation in five different climate zones was compared. This is based on 2017 ASHRAE F undamenta ls, Chapter 1 Section 8: numerical calculation of moist air properties.įrom the above equation, we can conclude the volume of condensate generated is a measure of the specific humidity of air entering the AHU, which is a function of the dry bulb and wet bulb of the air and local elevation. Ĭ ondensate volume can be calculated for specific situation s. Using a m athematical formula to calculate condensate volume can help users find the right medium. F ail ing to do so leads to unwanted problems, including biological growth such as algae. The pan must be drained continuously to prevent overflowing and causing any equipment damage. The condensate generated gets collected in a drain pan, which is placed below the cooling coil. The higher relative humidity also means that the moisture content of the air is higher (expressed as the humidity ratio or specific humidity ) and thus more moisture can potentially be condensed on the coil. Īs a result, it becomes easier for water to condense on the cooling coil. Upon completing a psychrometric chart, we can see when relative humidity increases from 60 % to 70%, dewpoint increases (see Table 1 ). Latent heat is transferred by moisture in the air to the coil via the process of condensing on the surface of the cooling coil. This is what happens at coil surface s inside an AHU. In engineering terms, condensation occurs when air hits a surface cooler than its dewpoint temp erature. Lower density air will result in a lower condensation rate. An air conditioner t hat moves air at higher velocity produces condensate at a higher rate because condensate volume is proportional to the supply flow rate and the air density. H umid air condenses easily, which means condensation is much more common in Miami as compared to Phoenix. When people think of condensation, it’s common to t hink of water droplets accumulating on a glass of water with ice or mist accumulat ing on a car windshield. Sizing the condensate trap is commonly overlooked, and there is no good literature that covers all aspects of design. It can cause health issues bec ause of mold and algae growth when not noticed early. I even had a windshield company take a look at it, and their analysis didn't see any problems or leaks.Īnyway, if someone could snap a photo of where the A/C drain is, or exactly where it is at, I would appreciate it.Ignoring coil condensate design make s engineers look incompetent. What leaks is not antifreeze or anything like that.just carwash water and soap. This drain is where you can connect the canned cleaner to take care of musty smells right?) My understanding is that there is an A/C drain tube (have yet to find) and an evaporator drain (a little tube that I found close to the firewall on the passenger side under the hood. Pouring a cup of water down each hole too exited under the running boards fine. I ran some weed eater string down the holes and didn't feel any blockage. I checked the sunroof drains, and they appear to be clear. Other than the carwash, when I run the heater or A/C around town, everything is fine.no leaks. I run the heater while I am going through the carwash, and I can see the drip coming from what looks like a foam seal. When I take it through the carwash, I see a drip coming from under the glovebox, which from what I understand is the evaporator box. I need a photo and location where to find the "A/C drain tube" as I suspect mine may be clogged. I have read many threads and I think I'm punchy at this point. Ok, it's 2:00am and I'm a super novice when it comes to truck repairs.
