Sizing The Exhaust Fan And Evaporative Cooler In Dry Cleaning Plants
Nearly every Dry Cleaner uses Evaporative Coolers, or Swamp Coolers as a few call them, in their place or even clothes washing area. Using refrigerated air conditioning would be too expensive chillwell portable ac for small room them. The steam boilers of theirs are putting out a huge selection of a huge number of BTU's of heating into the task area. To remove this much heat using air conditioning would cost a huge number of dollar per month. Due to this particular, the job part of the Dry Cleaner should have an Exhaust Fan that's able to making an extensive air exchange about every 1 1/2 minutes. I want to present you with an example to help you find the proper size exhaust fan for the Cleaner of yours.
Suppose you lease a space at a shopping center which is twenty five feet wide by eighty feet deep. The total square feet of this lease room is 2,000 sq. ft. Usually the front sales area is warmed up and air conditioned. Next, remove from the 2,000 sq. ft. the sales spot of yours of twenty five feet wide by 15 feet deep which totals 375 sq. ft. This actually leaves you with 1,625sq. foot. The boiler room is ten foot by ten feet (hundred sq. ft.) as well as the restroom is six feet by 6 feet (thirty six sq. ft.) which will total another 136 sq. ft. commonly not figured in to the cooled area.. This provides you with a final total of 1,489 sq. ft. of floor space in the job place to exhaust and cool. To get the cubic feet of the task area you need to measure from the floor to the roof deck. I mention roof deck as I do not recommend setting up a ceiling in the work region. This one keeps the heat lower in the room and makes the job area much hotter. Multiply the 1,489 sq. ft. by the fifteen ft from the floor on the top deck and you obtain a total of 22,335 cubic feet of area to exhaust. Divide 22,335 by one ½ (the quantity of minutes a air change) and get the total number of cubic feet of air to get rid of every minute, or the CFM. Under these conditions, I will install an exhaust air fan that's ranked at about 15,000 CFM. The most common exhaust fans used in Dry Cleaners are Grainger fans. You'll find Grainger outlets in almost all of the main cities in the United States, and that makes it convenient for purchasing parts and fans. I have invested in exhaust fans from Grainger for several years. I've discovered a way that any purchaser of Grainger, even if you've never purchased from them before, can get a ten % discount on the fans of theirs. In case you e-mail me I will let you recognize how you can get the discount in any Grainger store in the nation.
After that, you have to make up the spent air with an Evaporative Cooler. These work great in dried up climate areas. But even during more humid areas they give some cooling. You may just get a 10 degree temperature drop in a humid area, but on a 95 degree day, a light breeze of eighty five degree air is able to feel great as you work over a hot press. On a Dry Cleaner grow you will typically find them with a big commercial Evaporative Cooler. For the job space which I sized previously you will need to install a 15,000 CFM Cooler. Keep in mind whenever you look at Coolers, they generally give the CFM ratings in free air. Because you'll most likely have a duct structure cooling the project area, there's static pressure or restriction on the air flow from the Cooler. When you have a 15,000 to 16,000 CFM Evaporative Cooler, you'll probably have a good match with the 15,000 CFM exhaust fan. The static pressure of the ductwork will typically drop the CFM rating by a few 1000 CFM. The reason this fight is a useful one is because you want some amount of bad pressure in the work area, in other words a little more air exhausting from the home than is going to be delivered into the room. A typical Evaporative Cooler used in Dry Cleaning job areas is the Champion 14/21 SD or the Essick 14/21 SD. These're the most common since they're by far the most inexpensive designs sold. If you're willing to spend a little more money, I recommend visiting a Cooler that is going to last far longer. The Champion AS150 or even the Champion AS15012 are better built and longer lasting Coolers. If you need a much better reason of the reasons why they are better Coolers, you can kind these Coolers to an internet search engine and find articles composed about them.
I understand there's a lot of technical information that would be dull or boring to a lot of individuals, but in case you're eager to cool a Dry Cleaning plant I recommend utilizing this info. I've installed cooling and exhaust systems in Cleaners for decades in the Dallas/Fort Worth, Texas area. These formulas and devices have worked great. I am hoping these tips I've discovered can help others down the road.
