Project #3: Replace 25 year old Water-cooled Chiller with New High
Efficiency Water Cooled Chiller
Project Facts:
Standard Retirement, Chiller Life = 20 years
Old Water-cooled Chiller Efficiency = 0.82 kW/Ton
Title 24 Baseline Water-cooled Chiller Efficiency = 0.58
kW/Ton
New High Efficiency Water-cooled Chiller = 0.47
kW/Ton
Chiller EFLH = 67%
Cost of Water-cooled Chiller Installation (including
piping, etc.) = $250,000.
Energy Savings Calculation:
Annual Energy Savings = (0.82-0.47) kW/Ton x 450 tons x
0.67 x 8,760 hrs = 924,400 kWh
Annual Energy Savings = 924,400 x $0.10/kWh =
$92,400
Project Economics (w/o Incentives):
Simple Payback = ($250,000/$92,400) = 2.7 years
