Ambient mist sprinkler head

An ambient mist head for use with water having a low pressure, consisting of:

• a. a head body, having an upstream end and a downstream end, an inlet for a water source at said upstream end;
• b. up to four low pressure mist nozzles at said downstream end;
• wherein the head body consists of an elongated cylindrical body of about 36.8 mm in diameter and about 48.3 mm in length, a top located at said downstream end, four cross holes in radical direction of the head body located at said downstream end, a longitudinal hole along the length of the head body with an internal threaded portion located at the upstream end, which intersects with the cross holes at the downstream end, in which water flows through and exits via the four mist nozzles;
• wherein the internal threaded portion has a diameter selected from the group consisting of about 12.7 mm and about 19.05 mm, for connecting directly to said hose line, said four cross holes being spaced equidistant from each other in a circumference of the elongated cylindrical body proximate said downstream end;
• and the cross holes are about 11.43 mm off from the top;
• each of said low-pressure mist nozzles being spaced apart from each other such that a mist stream exiting from one mist nozzle does not intersect a mist stream exiting from any other mist nozzle proximate and distal said mist head;
• wherein said low pressure is selected from the group consisting of about 60 psi (414 kPa) and from about 100 psi-120 psi (690 kPa to 827 kPa).

An ambient mist head for extinguishing a fire using water at a low-pressure consisting of:

• a. a head body having an inlet for a fluid source at a first extremity;
• five outlets at a second extremity;
• and a cavity within said head body connecting said inlet to said five outlets;
• wherein each of said five outlets has a mist nozzle tip;
• wherein four of five outlets are at each corner of the body and one of said five outlets is at the center of the body;
• b. five low-pressure mist nozzles, each being attached to said body at each of said outlets;
• wherein four of the five low-pressure mist nozzles are attached equidistant on a beveled surface angled at 45° along said head body between said first and second extremity, and the fifth low-pressure mist nozzle is attached centrally normal to said second extremity;
• wherein said low pressure is selected from the group consisting of about 414 kPa and from about 690 kPa to 827 kPa;
• and
• c. a threaded hole drilled into the body for each mist nozzle tip;
• said threaded hole being angled into the head based on a required angular placement of each mist nozzle tip;
• each mist nozzle tip being threaded and/or screwed into the body;
• the height of the body is about 36.83 mm;
• the full length is about 48.26 mm the length of the angular portion of the body is about 12.7 mm.
