Problem solved through pump selection and spray direction.

I want to provide my farm animals with a stress-free environment...
I run a dairy farm. In summertime milk yield decreases significantly because the cows become stressed as a result of the temperature inside the cowshed reaching as high as 40 degrees C. I can't afford to install and operate an electric air conditioning system. Spraying water would be an efficient means of reducing the temperature, but the floor would be constantly wet. Can you recommend a spray nozzle to me that will produce a spray that will have a cooling effect, but whose spray is fine enough not to wet the floor? I'll use ground water, so some foreign matter may be present in the water source.

Problem solved through pump selection and spray direction.

A nozzle that sprays two mixed fluids produces a fine mist and does not clog easily, but the sound produced by the flow of air from such spray nozzles would cause your cows stress. Therefore, we suggest you use an airless type spray nozzle with an orifice diameter of about 0.4 mm. As a measure to counter clogging, you should use a spray nozzle that has a built-in compact filter. This will allow you to maintain a stable spray for long periods of time. We recommend that you operate the spray nozzles at a (rather high) water pressure of 5-7 MPa. Operating costs for your pump will not be too high because the flow rate is low. You can reduce the overall cost of the system if you install the spray nozzles in copper piping (lagged with vinyl) at ceiling level. A droplet of about 80 microns will evaporate before reaching the floor, and the temperature in your cowshed will decrease by some degrees due to the evaporation of the water droplets. It would be also very efficient to install a timer on the pump and to set it so that it sprays water at set intervals.
