delta T

Term to express temperature differences

Delta T is a term given to a difference in two specific measurements. Commonly applied to temperature differences for CRAC units, it can be applied to any piece of equipment.

Specifically the delta T for a CRAC is the temperature difference between the hot air going into the CRAC and the cold air going out from the CRAC.

Delta T is expressed as a temperature and mathmatically is:

Delta T = inlet temperature - outlet temperature
