are preferably oversized to obtain highest reasonable temperature
differentials, which also allows the plant supply temperature to be
raised in moderate weather conditions. Metering water to each load
also obtains the greatest possible system diversity.
This system can utilize chillers of different capacities and easily
allows any one of several machines to operate in a standby mode.
‘‘Free’’ winter cooling can be incorporated as part of a chiller or can
be added into the system, preferably precooling the system return
water. The direction of flow in the floating-bypass line combined
