Malaysia Best Mist Cooling Systems - How to Make a Mist Cooling System

Mist Cooling Systems

are popular in dry, hot areas, where evaporative cooling works best. These misting systems are found around patios and swimming pools, as well as many public areas. They work by spraying a fine mist of water into the air, which then quickly evaporates, making the air seem cooler. It can be compared to walking through a light fog, with similar cooling characteristics. Mist direction depends on how the nozzles are positioned, which is a matter of personal preference. Depending on the desired coverage area, this project should only take a day or two.


Things You'll Need:
Measuring tape
Vinyl tubing, 1/4 inch in diameter
"T" shaped vinyl tubing connectors
Mist heads
Plastic wire staples
Connector, hose faucet to tubing
Teflon tape
Scissors
Hammer

Instructions to Make a MIST COOLING SYSTEMS

1. Measure the area where the mist system will be located. For instance, if the hose faucet is to the side of the patio, measure from the faucet to the patio cover support, up the support and across the edge of the patio awning. The mist system can also run along the sides of the patio awning, if desired. This is the amount of vinyl tubing needed, plus 3 feet, just in case.

2. Wrap the threads of the outdoor faucet with Teflon tape and screw on the hose to tubing connector. Insert the tubing end into the vinyl tubing into the connector. It will be a tight fit since it is a pressure fitting; the tightness of the fit keeps it in place.

3. Connect the tubing to the patio supports or to the house, using the hammer and the plastic wire staples. Do this loosely at first, just enough to keep the tubing in place. This way, you an adjust the tubing as necessary. These plastic wire staples will hold the tubing in place without crushing it.

4. Determine where mist heads are needed. This is a personal preference. You can install mist heads from every foot to three feet apart and still be effective. Do not have a mist head spraying directly into a window or on a painted wooden surface, as water damage could occur.

5. Cut the line every place a mist head is desired with scissors. Cut the excess off the end, but keep it nearby. Place the "T" connections into these cuts. Cut about an inch of tubing from the excess, and place on end onto the "T." Repeat until all the "T"s have tubing on them. The end cut of the tubing is where the last mist head will go. There is no need for a "T" here.

6. Place the mist head into the tubing that is attached to the "T"s. Place a mist head at the end of the tubing. Turn on the water and check for leaks, as well as any mist heads that are not working. If some of the heads are not working, just replace them.

How To Use Patio Misting Systems: Mist Cooling Systems for Patios

We have all seen those cheap patio misters they sell at the big box stores. For $29.00 you basically get a mini-spinkler system that connects to your garden hose and sprays small droplets of water on you and your guests. Of course you are a little bit cooler, but do you really want to be soaking wet at a barbecue? On those hot days, there's no doubt that having cooling systems outside sounds like a good idea. However, put down the cheap misting system and check out patio misting systems that really work. Here's how to cool off your patio with patio misting systems.

1. Choose a high pressure patio misting system. It really is all in the pressure. With a higher pressure misting system, the nozzles can be pinched down tighter, producing a micro-fine mist that just floats in the air, more like fog. The cooling effect comes not from getting everyone wet, but from the evaporation of the mist into the air. Evaporation is a chemical process that actually uses heat from the air. With millions of tiny droplets evaporating in the air, serious cooling is the result of these patio misters. Choose a pump that can produce 1000 psi or more to achieve full evaporation.
2. Hang the misting lines at the appropriate height. Depending on the typical humidity level in your area, lines may need to be installed a couple of feet higher to get the full evaporation and avoid wetting. Another option is to use smaller nozzles and simply use more of them.
3. Choose the right nozzle spacing. Most mist system sources will offer lines in 24, 30, or 36 inch spacing. The closer you position the nozzles, the more cooling you will get. But if it is too much, or if it is too humid in your area, you may see some wetting. Follow the advice of a good misting system website or salesman, and don't be afraid to ask a lot of questions. See the following link to the same site where I got my Patio misting system. They have a very cool "Build-It Yourself" tool where you can type in your own temperature, humidity, height of install, etc. and see what the recommended specifications are. Other sites probably have something similar.
4. Choose the right nozzles. Again, seek advice, but larger nozzles cool better, as they produce more mist. But take it too far and you'll get wetting down below.
5. Filter your water if necessary. If your water contains calcium or other particles, install an inline filter right after the pump to be sure your misting nozzles don't clog. Cleaning nozzles isn't that tough, but it is time consuming. A $50 filter should take care of it though.

Now you know what to look for in these patio cooling systems. Basically, get yourself a quality system and make sure to get some help with the design first. A well designed misting system can be an amazing addition to any backyard or patio. A cheap one or a badly designed one can be a nightmare for your party guests!
