MIST SYSTEMS
Misting systems have been in use for decades as an economical and efficient means of environmental control. Mist system applications include outdoor cooling, special effects, humidification, and odor and dust control. Each application has specific design requirements for the misting system depending on the desired results. In some cases, the misting systems should completely surround the area and in other cases, the mist system is simply a single line run down the center of the area. Properly designed misting systems require an understanding of the area and the misting systems required results.
What is a Misting System
A misting system can be defined high pressure water that is forced through a specialized nozzle resulting is very fine droplets that float in air and evaporate thereby reducing the ambient temperature. It is recommended that pressure above 500 PSI is used. Most mist system requirements will demand pressure of 1000 psi. Pressures below 500 psi will produce larger droplets and result in excessive moisture on the ground and inefficient cooling capabilities.
Requirements for Misting Systems Design
One of the first uses for misting systems was for animal cooling. This application was first introduced In the 1950’s. The systems offered a very economical means of cooling both cattle and poultry. Mist systems were later introduced into the swine industry. Because of the unique properties of a properly designed mist system, they were able to provide for an improved product for the farmer. For cattle, the misting system reduced the temperatures enough to allow for increased milk production and increased weight for beef during the summer months. For poultry, the mist system effectively addressed the inability for the birds to cool themselves during the extreme summer heat and resulted in less mortality and better egg and meat production. The same results were obtained for the swine industry as well. Overall, the high pressure misting system improved the product and the revenue generated by the various agricultural farmers during the peak summer months.
Misting systems were used extensively for these industrial applications for decades but did not expand into other obvious uses for people until the 1980’s. In several key desert markets, misting systems started to be seen cooling people in restaurants and homes around 1984. The results were similar to the agricultural mist systems except the need for complete evaporation was emphasized due to the need to avoid any level of moisture build up on the business patrons or the residential patio. Although the mist systems were very similar in design and equipment to the industrial systems, they did require the development of a few new concepts and improved equipment.
For restaurant or residential patio cooling, the misting systems design will require a high pressure mist line to be placed on all open sides of the patio. It is important that hot air is prevented from entering the patio due to an open side not having a mist line installed. The mist system lines should be placed on the perimeter of the patio usually at a height of between 8 and 10 feet. The mist nozzles can be spaced between 18 inches and 36 inches depending on the overall conditions on the patio and the climate. If properly designed, all of the water from the misting system will evaporate and will result in temperature reductions of up to 35 degrees Fahrenheit. Fans can also be included if additional air circulation is desired or required.
For open areas that do not include a covered patio, the misting systems cooling capability may be diminished due to a lack of shade and the inability to mount the mist system directly overhead. Adding fans to the misting systems design in this case will improve its cooling capacity and its overall effect. When no structure exists, the mist system can still be used by laying it on the ground around the area to be cooled and spraying the mist directly upwards. As long as a high percentage of the mist is allowed to evaporate, the required cooling will take place.
Because a high pressure mist system provides such small droplets of water, it is also a very effective means of creating humidification for enclosed areas such as greenhouses or wine storage facilities. Key considerations for these mist systems include the ambient temperature and relative humidity of the existing air as well as the available air exchange within the facility. Other humidification uses for mist systems include increasing humidification for textiles plants and wood processing facilities. Mist systems can also be effectively used to improve the curing process for concrete. In all these cases, the end product is significantly improved by the mist system and the commercial operation can see financial benefits that out perform other less effective means of humidification.
In almost all humidification applications the purpose of the mist system is to maintain an established level of humidity regardless of the outside conditions. This manipulation of the environment provides a more consistent product for the commercial operation and allows for a higher quality of goods to be offered to the consumer. . The ideal humidity level for each different application varies but the capability of the misting system to achieve the desired result is a proven factor. This level of environmental control provided by the mist system has allowed them to be considered a required addition when humidity control is required.
As with all mist system applications, humidification projects require a careful consideration of the area to ensure proper design of the system so that desired results can be achieved. The primary concern is always to avoid moisture fallout which can adversely affect the product being produced. Including fans for added air circulation, incorporating small orifice nozzles, and considering specific placement of the mist system lines and the nozzles will determine the effectiveness of the misting system.
As with animal cooling, a properly designed and installed misting system will provide improved product results. Wineries will loose less wine through evaporation, wood processing plants have less scrap and straighter lengths, textiles mills can produce stronger fabrics with less equipment problems and maintenance. Overall commercial operations can be dramatically improved leading to increased profitability.
Each application will vary and each project has specific requirements so the system design is a key to mist system efficacy. For help or input or your mist system design contact Fogco at 800 607 6478 or visit us on the web at http://www.fogco.com
