Recently installed three dual-circuit modular water chillers with scroll compressors, total capacity 170 tons. Unless load is a good match to a given number of compressors (which is rare), frequent compressor cycling is the norm. Compressor cycling adds & subtracts capacity in fairly large increments. The chilled water system is constant flow. Chiller mfg. recommends putting VFDs on the chilled water pumps and making it a variable flow system. How would that be better with respect to compressor cycling?
