Roof Cooling With Intermittent Water Sprays
Sprays fine mist not water.
Roof cooling with intermittent water sprays. The thermal response of the roof with intermittent stepwise spraying variation is modeled by introducing an equivalent fictitious temperature that accounts for meteorological conditions roof to sky radiation and evaporative effects during roof wetted periods. 1 hours of intermittent use per fill. Evaluation of a direct evaporative roof spray cooling system there are numerous other examples on the web with different approaches to the problem. A review on cooling by water evaporation is found elsewhere 10 11.
A novel method to design water spray cooling system to protect floating roof atmospheric storage tanks against fires iraj alimohammadi 1 farshad nourai 32 4mohammad javad daryalaal amir masood ghasemi 1 department of occupational health engineering school of public health iran university of medical science. Applied energy 34 1989 69 77 simplified model for the behaviour of a roof spray cooling system p. Cool roof coatings are white or special reflective pigments that reflect sunlight. The thermal response of a roof to an intermittent controlled spray is modeled.
Method to distribute the water spray over the roof. In the present work a general analysis of the roof spray evaporative cooling is presented. Products are available for most roof types. Brass stainless steel orifice misting nozzle with carabiner for easy carrying.
Our company specializes in producing highest quality misting systems for residential commercial industrial and agriculture cooling applications with over 30 years of combined experience in manufacturing high pressure water pumps mistcooling inc. Termine experimentally the practicability of intermittent water spraying and external movable insulation with and without a closed roof pond. The effect of intermittent spraying of a building s roof on the cooling load of the building is investigated. Coatings are like very thick paints that can protect the roof surface from ultra violet uv light and chemical damage and some offer water protection and restorative features.
Instead of spraying water on the roof you should apply a cool roof coating to cool your roof down. No matter what the design they all have two things in common. In 1972 niles 11 continues experiments on skytherm followed by jain and rao 12 who investigates the cool ing effect of movable insulation roof spray with and without a roof pond. The windchiller with stainless steel orifice mist nozzle is an advanced affordable hand held fan mister that keeps users cool and comfortable during summers.
The model considers the actual meteorological conditions as an established harmonic series. Cool roof coatings are white or special reflective pigments that reflect sunlight. Coatings are like very thick paints that can protect the roof sur.
