Result Interpretation

ASHRAE RP-1452 Component-Based Enclosure Cooling Load calculator computes Total zone cooling load in W using the defined engineering formula and the input values provided. Total zone cooling load is expressed in W. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Conduction heat gain = 1250
  • Solar radiation heat gain = 840
  • Infiltration sensible heat gain = 320
  • Internal sensible heat gain = 960
  • Internal latent heat gain = 280

Expected Result:

  • Total zone cooling load = 3650

Engineering Interpretation:

Under the given input conditions, the calculated result is: Total zone cooling load = 3650 W.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
