The Evolution of HVAC Technology: From Basic Comfort to Smart Systems
For over a century, Heating, Ventilation, and Air Conditioning (HVAC) systems have played an integral role in creating comfortable and healthy indoor environments. From rudimentary methods to today’s advanced smart technologies, the evolution of HVAC has been remarkable. Let’s explore this journey and see how HVAC has transformed from providing basic comfort to becoming a vital part of sustainable, smart living. The Early Days of HVAC: Basic Comfort In the early 20th century, HVAC technology was in its infancy. Mechanical ventilation systems were designed primarily for industrial use, aimed at improving air quality in factories. Residential heating relied on coal or wood-fired stoves, while cooling was limited to natural ventilation and ceiling fans. The first major leap in HVAC came with the invention of modern air conditioning by Willis Carrier in 1902. His system, initially intended for humidity control in printing plants, quickly found applications in public buildings, theater...
