DEVELOPMENT OF THE WORLD’S FIRST SMALL-SCALE TWO-STAGE ABSORPTION CHILLER/HEATER/HOT-WATER SYSTEM


Ever since the Carrés first introduced absorption refrigeration technology to the world in the 1850s,
efforts have been made to successfully develop residential and light commercial absorption heating and
cooling systems. There have been some successes, like the ammonia/water systems developed and sold
in the U.S. during the 1970s, but they were largely eclipsed by eve- improving vapor compression
systems. There have also been failures in trying to overcome today’s market price and performance and
reliability requirements that have relegated absorption systems to micro-niche markets. Development of
the world’s first small-scale two-stage absorption chiller/heater/hot-water system seeks to provide
constrained energy markets with viable solution to growing electricity demand problems. This paper
describes the development of this new technology.
