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.

Chiller full and part load efficiencies have improved significantly over the last 10 years (Chillers with NPLVs of 0.35 kW/ton are available) to the point where future chiller plant energy performance will have to come from chiller plant design. ASHRAE Standard 90.1-2001 includes mandatory requirements for minimum chiller performance.
2020-6-24 · per nominal ton (3.2 L per kW) of cooling for tempe rature stability and accuracy in normal air-conditioning applica-tions as well as heat machine applications. 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
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.
These requirements supersede the requirements in Tables 6.8.1A to 6.8.1J of ASHRAE/IESNA Standard 90.1. a. Water Cooled Centrifugal Chiller Efficiency. Water cooled centrifugal water chilling packages shall meet the efficiency of either path A or path B as defined in Table C-3.

Air Cooled, with Condenser, Electrically Operated ☺Tip: To convert from COP to kW/ton; COP = 3.516/(kW/ton) To calculate EER = Tons x 12/(total kW input .
From Table P-6 (RTAA Performance Data), an RTAA 125 at the given conditions will produce 120.1 tons with a compressor power input of 136.3 kW and a unit EER of 9.8. 3. To determine the evaporator pressure drop we use the flow rate (GPM) and the evaporator water pressure drop curves, Figure F-1. Entering the curve at 276 GPM, the pressure drop .
The chiller system is recirculating 40 gallons per minute of water that is chilled by 24 degrees F and using 24.8 kW/hr of electricity to produce the refrigeration. With this information you can calculate chiller efficiency in terms of the energy efficiency ratio, or EER, and the coefficient of performance.
