The defaultvalues for SUPPLY-STATIC and SUPPLY-EFF will then be calculated based upon thedefaulted values in columns 2 and 3.SUPPLY-EFFMOTOR-PLACEMENTis an alternative to specifying values for SUPPLY-DELTA-T andSUPPLY-KW. It is used in conjunction with SUPPLY-STATIC andSUPPLY-MECH-EFF. It is defined as the overall efficiency ofthe supply fan at design conditions (expressed as a decimalfraction). Overall efficiency is the combined efficiency ofthe fan and motor. The default value can be found in TableIV.36 based on SYSTEM-TYPE.Input for this keyword is the code-word that specifieswhether the supply and return fan motors are located insidethe airstream or outside of the air stream. The SYSTEMSprogram uses this information to determine if the heat lossof the motors is to be added to the supply and returnairstreams. See Table IV.37 for the applicable code-words.IV.225 (Revised 5/81)
