Above thisvalue, the machine adjusts capacity by unloading.Between MIN-RATIO (from the PART-LOAD-RATIO instruction)and this ratio, the machine has unloaded as far as itcan and is using hot gas bypass to make up the difference.Below MIN-RATIO, the machine cycles on and off.specifies fan electric energy/hermetic reciprocatingchiller capacity (see HERM-CENT-COND-PWR keyworddescription).specifies the hermetic reciprocating chiller condensertype by code-word (see HERM-CENT-COND-TYPE keyworddescription).specifies the maximum part-load ratio of a reciprocatingchiller at which hot gas bypass occurs (seeHERM-CENT-UNL-RAT keyword description).specifies fan electric energy/open centrifugal chillercapacity (see HERM-CENT-COND-PWR keyword description).specifies, by keyword, the type of condenser of an opencentrifugal chiller (see HERM-CENT-COND-TYPE keyworddescription).specifies the fraction of open centrifugal chillercompressor electrical input energy that is converted toheat and rejected by the cooling tower. This is anexpression of the efficiency of the compressor motor.specifies the maximum part-load ratio of an opencentrifugal chiller at which hot gas bypass occurs (seeHERM-CENT-UNL-RAT keyword description).V.26 (Revised 5/81)
