VFD Energy Savings for Blast Freezer Compressor

1 post / 0 new

I am trying to determine the rough savings of installing a VFD on an existing compressor for a condensing unit that serves a blast freezer but I'm not sure how to go about that calculation.

I know the existing compressor motor size is 60 HP, and the blast freezer operates about 3 months per year. The blast freezer is kept at  -22 degC.

Any thoughts on how to calculate existing energy usage and the savings by installing a VFD? Can this be modeled in eQUEST?
