LB-07-010 -- 100 Ton Absorption Chiller/Heat Pump Demonstrates the Real Cost of Saving Energy PDF

A steam-fired demonstration of an absorption chiller/heat pump has now completed eight months of operation. This unit supplies 100 tons of chilling and 3.2 million Btu per hour of hot water simultaneously from 2 million Btu/h of 80 psig steam. It is installed at a poultry processing plant, where it prechills the cold water for the continuous chiller and preheats the hot water for the continuous scalder. It operates on a 20/5 basis automatically and completely unattended. The savings in both natural gas and electricity add up to over $110K per year for this demonstration project. The simple payback is approximately 1.8 years. Those savings are replicable in many applications and represent only one of many overlooked opportunities in the energy efficiency field.
