The equation will beused to describe the capacity of a double-bundle chiller asa function of exit water temperature and entering condenserwater temperature. This function should be normalized sothat f(CHILL-WTR-T, DBUN-COND-T-ENT) = 1.0. When in heatrecovery mode, DBUN-COND-T-ENT is used in place of the actualentering condenser water temperature to eliminate theeffect of the entering water temperature on the capacity.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation definesdouble-bundle chiller capacity correction factor as afunction of the difference between the exiting condenserwater temperatures in the heat recovery and non-heatrecoverymodes. It is normalized so that if 6T = 0, it = 1.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. The equation will describethe electric-input ratio of a double-bundle chiller as afunction of part-load ratio.accepts the U-name of a CURVE-FIT instruction that definesa bi-linear or bi-quadratic equation. The equation will beused to describe the electric input ratio adjustment factorof a double-bundle chiller as a function of exit water temperatureand entering condenser water temperature. Thisfunction should be normalized so that f(CHILL-WTR-T, DBUN­COND-T-ENTJ = 1.0. When in the heat-recovery mode, DBUN­COND-T-ENT is used to eliminate the effect of the enteringcondenser water temperature on the electric input ratio.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. The equation will expresselectric input ratio as a function of "TRISE" (seeDBUN-CAP-FTRISE).V.42 (Revised 5/81)
