HVAC (heating , Ventilation and Air conditioning) BLOG

  For over three decades, I've walked through thousands of mechanical rooms across the globe. From pharmaceutical cleanrooms to sprawling data centers, one critical flaw repeatedly emerges, silently draining budgets and prematurely aging equipment: HVAC Short-Cycling. It's not just an inconvenience; it's a multi-thousand-dollar systemic failure that often goes misdiagnosed. Many blame "faulty equipment" or "aging infrastructure," but the root cause is frequently far more fundamental: improper sensor placement and incorrectly configured control deadbands. The Mechanics of Self-Destruction: Why Short-Cycling Kills When a compressor starts and stops too frequently (short-cycling), it subjects the entire HVAC system to immense, unnecessary stress: Lubrication Breakdown: Compressors rely on a consistent run cycle to ensure lubricating oil returns from the system lines. Short-cycling prevents this, leading to oil starvation, increased friction, and eventual b...

  Choosing the right location for a data center is one of the most consequential decisions an organization can make. It impacts everything from initial capital expenditure to long-term operational resilience and energy efficiency. As a global HVAC and MEP consultant with over 30 years of experience, I have seen firsthand how site-specific variables—such as ambient temperature, power reliability, and local regulations—can either streamline a project or become a multi-million dollar bottleneck. To help my clients and colleagues navigate this complexity, I have developed a Free Data Center Site Feasibility Survey . Why Site Feasibility Matters In the era of high-density AI workloads and modular construction, a "good enough" site no longer exists. You need a site that balances technical requirements with strategic growth. Key factors include: Power Availability & Redundancy: Can the local grid support your ultimate capacity, and are there diverse paths for utility feeds? Cli...
