Abstract

Misting systems for poultry housing have traditionally been characterized using evaporative cooling efficiency. This works well for evaporative pad systems, but poorly for misting systems since they are strongly affected by water pressure and ventilation rates. The fraction of the misting rate which evaporates (designated as β) was analyzed for two previous studies and data obtained for this study using theoretical relationships. A theoretical analysis relating individual droplet evaporation to evaporation rates showed that evaporation efficiency is strongly affected by initial droplet sizes, which are affected by water pressure in conventional misting systems. Analysis of test data for poultry houses showed that β increases with system water pressure; β ranged from 0.09 at a pressure of 280 kPa (40 psi) to 0.57 at a pressure of 3400 kPa (500 psi).
