(-STACK-FU)(-TEX-FPLR)(-FPLR)For a diesel generator or gas turbine generator, the UA ofthe exhaust heat recovery heat exchanger will be calculatedas an exponential function of the nominal electricaloutput. This equation will take the rather unusual form:UA = constant coef. x (electrical output)linear coef.or z = axbFor a diesel or gas turbine generator, the temperature ofthe exhaust gas is calculated as a linear or quadraticfunction of the part-load ratio.For a boiler, the part-load efficiency is calculated as alinear or quadratic function of part-load ratio, as shown inthe equationEQUIPMENT-QUADAbsorptions ChillersABSORI-CAP-FTABSORI-HIR-FPLRABSORI-HIR-FTABSOR2-CAP-FTABSOR2-HIR-FPLRABSOR2-HIR-FTEffpart = Efffull x (a + bPLR + cPLR2).The keywords in the EQUIPMENT-QUAD instruction are definedbelow.This command word informs the PDL Processor that the data tofollow will override defaults by associating performanceequations, or curves, to designated performance keywords.accepts the U-name of a CURVE-FIT instruction that defines abi-linear or bi-quadratic equation. That equation will beused to override the default equation and define thecapacity correction factor of a one-stage absorptionchiller. (see -CAP-FT above).accepts the U-name of a CURVE-FI.T instruction that defines acubic equation. That equation will be used to define theheat input ratio correction factor of a one-stage absorptionchiller as a function of part-load ratio (see -HIR-FPLRabove).accepts the U-name of a CURVE-FIT instruction that defines abi-linear or bi-quadratic equation. That equation will beused to define the heat input ratio correction factor of aone-stage absorption chiller as a function of temperatures(see -HIR-FT above).is like ABSORI-CAP-FT for a two-stage absorption chillerwith economizer.is like ABSORI-HIR-FPLR for a two-stage absorption chillerwith economizer.is like ABSORI-HIR-FT for a two-stage absorption chillerwith economizer.V.40 (Revised 5/81)
