Anyremaining recoverable heat from the diesel can be used on level 2.On level 2 the multiple demands are met by the supplies in proportionto their loads. The supplies on each level are used sequentially,i.e., the double-bundle chiller heat is used before the dieseljacket, because it is first in the list.4. The default HEAT-RECOVERY (directing the condenser heat from adouble-bundle chiller to satisfy space heating) is overriddenwhenever the HEAT-RECOVERY command is used. Therefore, if the userwants to enter HEAT-RECOVERY equipment and processes in addition tothe DBUN-CHLR, the user must explicitly enter the DBUN-CHLR as asupply and SPACE-HEAT as its demand.5. Only one solar supply is allowed at each level. The user must decidethe purpose of the solar source for each level and cannot, forexample, enter the following:HEAT-RECOVERYSUPPLY-1 = (SOL-PROCESS-HEAT, SOL-SPACE-HEAT)DE~IAND-1 = (PROCESS-HEAT, SPACE-HEAT) ..His intention, in this example, was to satisfy the domestic hot wateror process heating demand first and to contribute to meeting thespace heating demands after the hot water demand is met.V.69 (Revised 5/81)
