Poultry & Dairy Farm Evaporative vs Chilled Water Cooling in Al Ain & Sharjah

Agricultural and livestock operations located in the desert interior of the UAE (such as Al Foah, Al Ain, and Dhaid in Sharjah) house high-value dairy cattle and commercial broiler poultry operations. High ambient heat combined with rising summer humidity causes severe livestock thermal stress, resulting in sharply reduced milk yields and high poultry mortality.

While traditional farms rely on evaporative cooling pads, their cooling effect diminishes when ambient relative humidity climbs above 40%. Supplemental rental chillers feeding chilled water fan-coil loops provide positive sensible cooling regardless of outdoor humidity levels, safeguarding livestock welfare.

Engineering Principles & Technical Specifications

Livestock cooling requires calculating metabolic heat generation (a high-yield Holstein dairy cow produces ~1,500 to 1,800 Watts of metabolic heat) plus envelope solar radiation through corrugated sheet metal roofs, requiring rapid air exchange with high-velocity air movement ($>2.5 \text{ m/s}$) over the animals.

Step-by-Step Technical Execution & Mobilization Protocol

To ensure seamless reliability under extreme UAE summer ambient conditions (reaching +50°C to +52°C), our engineering logistics teams implement the following structured workflow:

1. Livestock Thermal Heat Index (THI) Assessment: Evaluate barn dimensions, herd density, and ambient humidity patterns to calculate Temperature-Humidity Index (THI) reduction targets.
2. Corrosion-Resistant Skid Deployment: Deploy skid chillers fitted with heavy-duty coated condenser coils capable of resisting high ammonia and dust concentrations prevalent in agricultural yards.
3. Secondary Hydronic Ring Main Installation: Run flexible supply and return lines around the barn perimeter, connecting to overhead chilled water fan-coil units mounted above feeding alleys.
4. Automated Dual Setpoint Cycling: Program controllers to modulate chiller tonnage automatically between scorching daylight peaks (+48°C) and cooler nighttime conditions.
5. Emergency Standby Generator Integration: Provide automatic transfer switchgear linked to rental generators to prevent catastrophic cooling loss during rural power grid disruptions.

Common Operating Pitfalls & Desert Condition Mitigation

Operating HVAC and power plant equipment across Dubai, Abu Dhabi, Sharjah, and coastal industrial zones like JAFZA presents severe thermodynamic challenges. The following table of risks must be actively managed:

• Ammonia Corrosion of Copper Heat Exchangers: Mandate full polyurethane or Blygold protective dip-coating on all fan coils and condenser fins exposed to barn atmospheres.
• Feather & Dust Clogging of Cooling Coils: Install coarse washable nylon pre-filtration screens on all air handlers and schedule daily compressed-air blow-downs.
• Excessive Bedding Moisture from Condensate: Design positive-slope PVC condensate drainage piping to discharge all coil runoff completely outside barn perimeters.
