    Default Water Mist cooling systems

    Hi guys

    I saw in the latest leasure Wheels someone is marketing a portable system with a pump and small jets to create this mist to cool your tent or camping area (similar to those at outdoor areas of restaurants). They quote either the use of a 12V pump or 220V, total cost starting at R1700.

    A friend told me the jets/nozzles can be found at hydraulics shops, and one would probably need some sort of a high pressure pump and some chilled water - any ideas out there for DIY?

    Obviously the pump will be very important. Marine shops sells a hi pressure 12v pump with a pressure switch normally used on yachts, starts at about R800 when I last checked.

    So if their price is R1700 incl the pump then you might battle to compete?

    They use mist systems like these at the croc park in Oudtshoorn, very effective.

    What if you use a normal compressor and a jerry can - compressor pressurize the can and another pipe goes out with the mist-nozzles.

    any irrigation shop will sell everything you need except for the plug to seal the can.

    otherwise just take a sealed hose pipe with the nozzles on and hog the closest tap

    I think most compressors will pack up if run continuously for a long period.

    The noise might make you rather unpopular in the camp!

    I don't think the water needs to be chilled. The cooling effect comes from the water extracting energy from the environment (or your skin) to evaporate. The evaporation is made easier when the droplets are smaller.

    Yip it's definitely not something Iíll be using that often. BUT when thereís no river to swim in, no shade, itís a nice 40íC outside with a low humidity and you know you have enough water with you for the weekend, then Iíll connect up the misting system. Here in the EC itís happening more often than usual
