Sensible versus latent heat, humidity, the sensible heat ratio, and why data center loads are predominantly sensible.

Learning objectives

  • Define sensible and latent heat and relate latent heat to moisture.
  • Calculate and interpret the sensible heat ratio (SHR).
  • Explain why IT loads are mostly sensible without assuming latent load is zero.
