Energy Cost Calculator for Water-Cooled Electric Chillers


Vary equipment size, energy cost, hours of operation, and /or efficiency level.

INPUT SECTION
Input the following data (if any parameter is missing, calculator will set it to the default value). Defaults
Chiller Project Type    New
Existing Efficiency *    kW/ton
Existing Capacity *    tons
New Chiller Type (by compressor type)    Centrifugal
New Capacity    tons 500 tons
New Efficiency    kW/ton 0.56 kW/ton
Energy Cost $ per kWh $0.06 per kWh
Quantity of Chillers to be Purchased    unit(s) 1 unit
Annual Hours of Operation**    hours 2000 hours
* Existing values should only be entered when Project Type is a replacement.
** Value entered should be equivalent full load hours (e.g., 1000 hours @ 50% load equals 500 hours.)

Your selection of a ton chiller unit will have a $ energy cost savings per chiller (over its estimated 23 year life expectancy compared to the base model).

Assumptions

  • "Base model" has an efficiency that just meets ASHRAE Standard 90.1.
  • Calculator assumes user is entering efficiency ratings based on ARI's 1998 Standard 550/590.
  • Lifetime energy cost is the sum of the discounted value of the annual energy cost based on assumed chiller life of 23 years.
  • Future electricity price trends and a discount rate of 3.2% are based on Federal guidelines.
  • $0.06 for electricity is the Federal average price in the U.S.

Disclaimer
This cost calculator is a screening tool that estimates a product's lifetime energy cost savings at various efficiency levels. Maintenance and installation costs do not vary significantly among the same product having different efficiencies; so, these costs are not included in this calculator tool. For a detailed life-cycle cost analysis, FEMP has developed a tool called Building Life-Cycle Cost (BLCC). This downloadable tool allows the user to vary interest rates, installation costs, maintenance costs, salvage values, and life expectancy for a product or an entire energy project.
