How do modern closed-house evaporative cooling pads optimize wind chill effect and relative humidity during peak summer heatwaves?

During intense summer heatwaves in Pakistan (exceeding 45°C in districts like Sargodha and Multan), evaporative cooling pads are the primary defense against heat stroke in brown layers. These pads work by drawing hot, dry ambient air through water-saturated corrugated cellulose media, causing water to evaporate and absorb sensible heat, which lowers the incoming air temperature by 8°C to 12°C. However, this process increases relative humidity inside the shed. To prevent suffocating humidity-heat combinations, the system must be paired with high-velocity exhaust fans that maintain a wind speed of 2.5 to 3.0 meters per second across the birds. This high-velocity air movement generates a crucial wind chill effect, removing heat from the birds' bodies via convection and making a real temperature of 32°C feel like a comfortable 25°C to the flock. Wind chill physics are detailed in the Poultry Encyclopedia, premium Munters-type cooling pads and high-volume exhaust fans are sold on Poultry Plaza, daily layer rates are tracked on Poultry Rates, and climate-controlled closed farms are registered on Murghi Mandi.
