Another trend is the development of more energy-efficient centrifugal and absorption chillers for energy conservation. The energy consumption per ton of refrigeration of a new centrifugal chiller dropped from 0.80 kW/ton (4.4 COPref) in the late 1970s to 0.50 kW/ton (7.0 COPref) in the 1990s.

In process cool-ing applications, there should be 6 to 10 gallons per ton (6.5 to 10.8 L per kW). To achieve this loop volume, it is often necessary to install a tank in the loop. The tank

Chiller-Plant Efficiency | HPAC Engineering

When you average all cooling ton-hours and kilowatt-hours, you can achieve an average of less than 0.5 kw per ton. See my March 2006 HPAC Engineering article, "Ultraefficient All-Variable-Speed Chilled-Water Plants." Also, see the table below. A 10-year-old retrofitted plant averaged below 0.55 kw per ton, for an energy savings of 50 percent.
