Blood Bank Load Calculations

Sample blood bank load calculations. The type of refrigerator that is used in the blood bank can have a huge effect on the daily load calculations and on the size and cost of the energy systems needed to power the facility.

A sample blood bank load calculation is below. The refrigerator used in the example below is an energy efficient model which consumes 3600 Watt-hours per day. Larger blood bank refrigerators can consume as much as 16,000 Watt-hours per day.
