Central air conditioning systems provide cooling to entire buildings from a central location. Operation necessitates a power source, primarily either natural gas or electricity. Electrical systems utilize electricity to power a compressor, condenser fan, and air handler to circulate cooled air. Conversely, gas-powered systems, also known as gas absorption chillers, employ natural gas as their primary energy source to drive the cooling process.
The choice between these two power sources carries significant implications for energy consumption, cost efficiency, and environmental impact. Electrically powered systems are often more prevalent due to established infrastructure and technological advancements that have improved their energy efficiency. Gas-powered systems were more common in the past when gas prices were lower and electricity was more expensive. Now a days electricity has proven to be more efficient.
