HVAC
While the necessities of life might not officially include heating and air conditioning, most of us would be significantly impacted if we had to go through life completely exposed to our local climate without relief. The HVAC Industry provides us with this relief by heating, ventilating, and air conditioning indoor spaces to our comfort, thanks to advanced mechanical systems and sophisticated controls that keep outside weather outside, and cozy atmospheres within.
CHALLENGES
Back during the Industrial Revolution, the HVAC Industry was born of simple ventilating fans that converted mechanical power into air flow, where the core challenge was how to efficiently convert this energy for the most benefit. Today, we largely face the same core challenge, though now it’s expanded to massive scales and much more complex applications.

DESIGNING FOR THE UNKNOWN
➤ HVAC design criteria is mostly standardized by historic climate profiles and third-party performance requirements, but as annual weather cycles continue to break records year after year, system designers are faced with the need to solve for future conditions that are generally unpredictable. This trend leads to overdesign and unnecessary costs, a situation that can’t be averted until climates stabilize or designs reach near-perfect efficiencies.
ENERGY CONSERVATION AND PERPETUAL SCRUTINY
➤ The HVAC Industry is under constant barrage due to its direct relationship between energy consumed to produce comfortable human space, and the impacts of this energy’s consumption on the wider global environment. Some reports claim that HVAC systems consume 38% of building-related energy and up to 25% of all final energy worldwide, and growing. In turn, regulators increasingly aim parallel carrot-and-stick tactics at the HVAC Industry, including new regulations, audits, incentives, and certifications.
MISSION-CRITICAL ENVIRONMENT CONDITIONING
➤ Though some might disagree, conditioning a Miami home in 110°F weather is not mission-critical in the same way that maintaining positive, hygienic, sterile air flow into a hospital operating room during an emergency surgery would be. HVAC applications cover a wide range of zero-fault tolerance conditions across commercial, industrial, and institutional facilities, plus more exotic uses such as onboard seafaring vessels and in mine shafts extending miles into the earth.
SOLUTIONS
The path forward in the HVAC Industry is clear: new technological advancements coupled with world-class process controls will grant HVAC systems the energy efficiency, reliability, and scalability that regulators and end-users demand. Whitman Controls is ahead of the curve, offering a full lineup of temperature, pressure, vacuum, and flow sensors ideally suited for HVAC and refrigeration applications.
