Most plug loads operate at a fraction of their nameplate electrical load, so, as a result, produce significantly less heat load than engineers may use in their cooling load calculations based on those nameplate values, continues Friedman. As CDA suggested, a professional is a way to go in this situation. Tabulated values are based on 78oF (25.6oC) for dry-bulb temperature Scope Technical Committee 4.7 identifies, evaluates, develops, and recommends procedures for calculating energy performance for the built environment.

Typical equipment with high heat generation in the Pharmaceutical industry: This list includes but it is not limited to the equipment installed inside cleanrooms. Guidance to meet that challenge is contained in a new standard from the society. Since there are no standards for establishing how the power consumption or heat rejection data or various plug loads is determined, it is difficult for engineers to accurately use this data in their cooling load calculations.
