SF-98-27-1 -- Applied Psychrometrics for High-Usage Freezers ✓ Most Recent

The refrigeration industry decided years ago that applied psychrometrics could be safely omitted in the engineering of dry-surface-type coils for freezers and their outer rooms. It was an acceptable decision at the time because latent heat gain in storage freezers of the day tended to be minor and the overall need for attention to psychrometric effects was minimal. The earlier freezers have evolved in large part into distribution-type freezers with high-use doorways and, because of a corresponding increase in moist-air infiltration, the consequences of latent heat gain are now often found to be major, and a full return to the principles of applied psychrometrics is needed by the industry.
