This invention relates to a method and system of distributing a fluid onto a selected surface comprising: a sprinkler system having a sprinkler head; structure for distributing the fluid through the sprinkler system where the sprinkler head has a first and second aperture for applying de-icing fluid in the winter and summer nutrients during the summer.
Many homeowners and businesses have sprinkler systems for irrigating lawns, vegetation, plants, vegetables and the like. Many of these irrigation systems comprise of a sprinkler system which is located underground having a plurality of sprinkler heads that pop up under the pressure of water applied by a pumping system. These sprinkler system and others have controllers which in many cases comprise of programmable units or computers to apply water on a desired area or surface at a selected interval. In other cases, sensors are utilized to monitor environmental conditions and activate the sprinkler systems at a selected interval under selected conditions.
Furthermore, there have been a variety of de-icing systems that have heretofore been designed in order to attempt to clear selected surfaces from the accumulation of snow or ice. Such systems are utilized so as to minimize human effort which may in certain circumstances lead to health conditions due to the age of the individual trying to clear the snow or ice. In other cases the de-icing systems are relied upon to quickly respond to conditions such as clearing of paths, driveways, sidewalks, parking lots, airplane runways, bridges, or the like.

Tubing can comprise of any material including PVC in a manner well known to those persons skilled in the art. The system 2 can also include a solenoid valve 50 that can be activated and de-activated again in a manner well known to those persons skilled in the art and shall be described herein.
A flow sensor 70 can be utilized to sense the flow of fluid and which flow sensor can include a preset timer. A pressure sensor 80 can be utilized in line to increase or decrease the spray pressure depending in the wind velocity or direction. In other words, each spray head 90,100,110,120,130 can include a pressure sensor which communicates with controller 160 so as to increase or decrease the pressure of fluid applied to each individual head in the event that the sensors sense for example wind conditions which may blow the de-icing fluid from one side of the driveway to another to produce uneven distribution of de-icing fluid over the entire desired or selected surface. A controller such as for example a programmable logic control (PLC) can be used to control the flow rate or pressure. By increasing the pressure of fluid flowing from one side of the driveway to another, environmental conditions such as wind may be compensated for so as to product a more even distribution of de-icing fluid on the selected surface 3.

The system 2 can also include ambient or environmental condition sensors 190 which sense the presence of snow, rain, wind direction and temperature and may be programmed to activate the system in the manner to be described herein.
In one embodiment, when the sensors 190 detect moisture as well as the ambient temperature, an electrical signal is sent to the digital controller 160. The digital controller 160 accesses a program which is operable to automatically activate the system 2 once selected parameters are reached, such as for example, length of snowfall, ice accumulation, temperature and the like.
For example, in one embodiment if the sensors 190 sense that the snowfall is present from 0-15 minutes the system 2 may be activated if other conditions are present such as temperature or humidity. In other cases, the system may be activated if the snowfall continues from 15-30 minutes.

Other enhancements may include wind control for spray units which control pressure or volume of spraying of each of the units so as to produce a more uniform spray on a first selected surface such as a driveway to compensate for wind direction.
Various spray patterns can be utilized such as low profile or horizontal. Moreover, the solution tank (20) may be filled with slow dissolve pellets, pucks or concentrates that mix with water or the like. The timer operation of the controller (160) is based on the input from the sensors (190). Moreover, automatic system pumpdown and purging can be utilized upon cycle completion.

As described above, the liquid storage tank holds the solution. In one embodiment the formulated concentrate controls solution comprises a potassium acetate and calcium magnesium acetate which is dispersed into the storage tank to create a temperature based solution. In other words, the concentration of potassium acetate and calcium magnesium acetate will be increased if for example extremely cold temperatures exist, whereas less potassium acetate and calcium magnesium acetate will be utilized if the ambient temperature hovers just below freezing. The controller 160 can automatically increase or decrease the concentration of de-icing fluid based on data and program resident in the digital computer. Furthermore, the controller 160 may be accessed wirelessly or USB connection to the internet so that the system 2 can be activated remotely from a different location.
The weatherized sprinkler heads 90,100,110,120 and 130 are designed to spray the solution onto the first or second surfaces before or during a snow or ice event controlled by a custom designed PLC panel that communicates with the internet. When the cycle is complete, the system pump 40 can reverse the pressure and purge all the flow tubes 60 empty. The solution is environmentally friendly and exhibits little if any corrosive effect.

In the summer embodiment, the sprinkler heads have configurations spray patterns, moisture sensors and controllers and upon input signals from the moisture sensors, the controller configures the spray pattern of the sprinkler head to allow more liquid to fall on areas that need it and less to fall on areas that do not need it. Another embodiment of the invention is that the system 2 can be integrated into existing lawn sprinkler systems 2. The pump 40 can also be used in the fall to purge existing underground water irrigation systems. Wind directional sensors 190 control the sprinkler flows to allow maximum spray pattern coverage on the selected first or second surfaces. Fertilizing solutions can be dispensed into the system 2 for the growing seasons for grass, gardens and flowerbeds all digitally controlled to activate a plurality of times a year. The invention described herein relates to a year round outdoor surface network system.

Formulated concentrated control solution is dispensed into the storage tank to create a temperature-based solution. When the system is triggered by sensors indicating snow or ice, solenoid valves will activate, pumps will engage the fluid to underground plastic tubes dispensed through weather resistant spray heads specifically designed to perform during wind events and deactivate when body heat is present. The weatherized sprinkler heads will spray the solution onto the surfaces before and during a snow event controlled by a custom design PLC panel that will have intelligent communication via the internet. When the cycle is complete, the system pump will reverse the pressure and purge all the flow tubes empty. The pump can also be used in the fall to purge existing underground water irrigation systems. Wind direction sensors control the sprinkler flow to allow maximum spray pattern coverage on the surfaces. Fertilizing solution can be dispensed into the system for the growing season for grass, gardens, plants and flowers, all digitally controlled to activate 3 or 4 times a year.
