We're considering some work to reduce the condenser approach temp. e.g 6°F to 1.6°F. In order to move forward I need to calculate the cost savings.
The system has a water-cooled centrifugal chiller. Can the cost savings be calculated by using site data e.g. gpm, temperatures, power cost? or, is there rule of thumb i.e. each 1°F change reduces power consumption xx% etc. Not quite sure how to approach this issue.
Can someone assist in calculating cost savings? Thanks.
