Case Study: Strategic Climate Control & Dehumidification
Project: Zayed Military College (CMW)
Location: Al Ain, United Arab Emirates
Focus: Resilience, Large-Scale Occupancy & Desert Latent Load Management
1. The Challenge: Extreme Aridity & Peak Occupancy Loads
Zayed Military College is a sprawling, fortress-like campus that combines traditional architectural elements with cutting-edge training technology. The Al Ain location presents a “dual-threat” climate:
- Extreme Thermal Swings: Ambient temperatures can fluctuate from near-freezing at night to over 50°C during the day.
- Sudden Humidity Spikes: While inland, Al Ain experiences intense humidity during specific seasonal transitions. In a facility with high-occupancy dormitories and auditoriums, the “internal” latent load from breathing and activity is massive.
- Sand & Dust Infiltration: Constant exposure to fine desert sand can clog cooling coils, leading to “wet-coil” syndrome where moisture trapped in dust becomes a breeding ground for mold.
2. The Solution: CMW-Standard Engineering Excellence
As a Command of Military Works (CMW) project, the HVAC systems—utilizing high-capacity SKM Air Conditioning solutions—are engineered for “fail-safe” operation and maximum dehumidification efficiency.
A. Dedicated Fresh Air Treatment (FAHU) The campus utilizes a centralized Fresh Air Handling system. These units are equipped with double-stage dehumidification coils. By cooling the air to a very low dew point and then utilizing Run-Around Heat Recovery coils to slightly reheat the air before distribution, the system ensures that “dry” air is delivered to every room without wasting energy.
B. Sand-Trap Filtration & Protective Coating To protect the dehumidification process, the units are fitted with high-efficiency sand louvers and multi-stage filtration. The coils themselves are treated with anti-corrosive hydrophobic coatings, which allow moisture to roll off easily, preventing the buildup of “sludge” that compromises both IAQ and efficiency.
C. Demand-Controlled Ventilation (DCV) In large assembly halls and training centers, the system uses $CO_{2}$ sensors to monitor occupancy levels. The dehumidification rate automatically scales up as more personnel enter the room, ensuring that the air never feels “heavy” or “humid,” even during peak capacity.
3. The Results: A Prepared & Healthy Environment
- Durable Infrastructure: The integration of CMW-spec dehumidification ensures that sensitive electronics in training simulators and server rooms are protected from moisture-related failures.
- Optimal Training Conditions: By maintaining a constant 40% – 45% Relative Humidity, the facility provides an environment that supports physical performance and mental focus for cadets.
- Sustainability & Efficiency: Despite the massive scale of the campus, the use of Energy Recovery Ventilators (ERVs) allows the facility to meet strict Estidama Pearl requirements, reducing total cooling energy consumption by up to 25%.
