PRED-LOAD-RANGEfor the equipment normally assigned to meet the electricload. This entry should include the heat power to move andcontrol the working fluid as well as the heat to thenormally assigned electric generating equipment.If the user does not wish to manage a load, no entry isrequired.is the predicted load range of the managed load in whichthe assigned equipment operates.ASSIGN-SCHEDULELOAD-ASSIGNMENTidentifies a list of three U-named SCHEDULE instructionsthat will schedule the assignment of the plant heating,cooling, and electric generation equipment. No entry ismade if the LOAD-ASSIGNMENT keyword is defined for thePRED-LOAD-RANGE. The scheduling of heating, cooling, andelectric equipment must not be combined in one SCHEDULEinstruction.identifies a list of three U-named LOAD-ASSIGNMENT instructionsthat specify the heating, cooling and electric generatingequipment to be assigned to the PRED-LOAD-RANGE. Noentry is made if the ASSIGN-SCHEDULE keyword has beendefined for the PRED-LOAD-RANGE.Rule: The total number of PRED-LOAD-RANGE keywords cannot exceed 10.Example 1:Example 2:This example shows how the cooling equipment assigned in Example 3of the LOAD-ASSIGNMENT discussion is used to meet the cooling loads.LOAD-MANAGEMENTPRED-LOAD-RANGE ;LOAD-ASSIGNMENT999(DEFAULT, CHILLERS, DEFAULT)By inputting DEFAULT where shown, the user allows the program todecide which heating and electric equipment to operate. If,however, the user wishes to assign the operation of heatingequipment, as specified in Example 1 of the LOAD-ASSIGNMENTinstruction, then the user specifiesLOAD-MANAGEMENTPRED-LOAD-RANGE ; 999LOAD-ASSIGNMENT; (BOILERS,CHILLERS,DEFAULT)A double-bundle chiller, DBUN, and an open centrifugal chiller,OPEN-CENT, are defined by a hypothetical PLANT-EQUIPMENTinstruction to be capable of producing 10 MBtuh of cooling. If theuser prefers to operate the double-bundle chiller in the winter andthe open centrifugal machine in the summer supplemented by thedoubl~-bundle chiller, the following steps should be taken.V.60 (Revised 5/81)
