5. The Unexpected Origins of HVAC Systems and Commercial Refrigerators
HVAC systems and commercial refrigerators, the backbone of modern comfort and convenience, have interesting roots that are often overlooked. In the case of HVAC systems, the “Father of Air Conditioning,” Willis Haviland Carrier, invented the first electrical air conditioner in 1902. Interestingly, this invention was spurred by the need to reduce humidity so that a printing company could get ink to adhere to paper in high heat. Carrier’s revolutionary idea stemmed from a foggy Pittsburgh train platform. Through the mist, he realized he could dry air by passing it through water to create fog, thus manufacturing air with specific amounts of moisture to control humidity.
Commercial refrigerators, on the other hand, owe their existence in part to a Scottish-born journalist named James Harrison. Harrison invented the first functioning refrigerator in the 1850s using ether, primarily to keep his beer chilled. This invention would later evolve into the modern refrigerator we know today. Fred W Wolf invented the first domestic refrigerator in 1913. He was an architect and refrigeration engineer. His invention, the domestic refrigerator,was also known as DOMELRE.
6. The Future of HVAC and Commercial Refrigeration: A Chilly Innovation On The Horizon
The future of HVAC and commercial refrigeration may hold an astonishing breakthrough that’s sure to give you a chill. Say hello to a groundbreaking technology known as the Crytocooler.
Cooling systems, including HVAC and commercial refrigeration, collectively account for 17 percent of the electricity used worldwide, and a whopping 8 percent of global greenhouse gas emissions. Given that our energy use for cooling might grow sixfold by 2050, the need for more efficient cooling systems becomes ever more apparent. But here’s where the Crytocooler enters the stage.
Imagine a device that can cool a piece of copper from over 100°C to significantly below room temperature without an external power supply. This seemingly magic trick is actually a feat of thermodynamics, courtesy of the Peltier element, a component often used to cool hotel minibars or CPUs in computers.
The Crytocooler can transform electric currents into heat currents, effectively creating a passive thermal circuit. What’s truly astounding is that this process can continue even after temperatures have equalized, allowing further cooling.
In essence, the Crytocooler takes advantage of the temperature difference between a hot object and its surroundings to create a voltage across a Peltier element, initiating a current that continues to flow and cool even after temperatures have become equal. This novel approach could revolutionize cooling in regions or situations where there’s no source of energy, or simply to save energy for cooling.
Of course, the technology is still in its infancy and has yet to be commercialized. But the potential is huge. Imagine cooling systems that can operate without consuming additional power, reducing both energy usage and greenhouse gas emissions. It’s a chilly innovation on the horizon, and it’s one that could transform the HVAC and commercial refrigeration industries for the better
