number of chillers (Fig 117b), the variable-speed pumps also can be controlled by the pressure drop across the condensers As a chiller is started or stopped, the control valve on the chiller condenser water circuit opens and closes The optimal number and size of pumps appear to be three 50 percent system capacity pumps on most of the multiple-chiller applications Table 112 is a tabulated analysis of the pumps for the chillers in Fig 117b This wire-to-water efficiency analysis indicates the number of pumps that should be run with various chillers in operation Even though two pumps are required to handle the maximum load of 9000 gal/min, this evaluation indicates that it is more efficient to operate all three pumps at full load
1161 Operating absorption and centrifugal chillers together
A problem that the variable-speed pump is solving is the operation of an absorption and an electric chiller from the same cooling tower installation In the past, this was unacceptable because of the difference in condenser supply water temperatures The absorption machine required fairly constant supply water temperature, while the electric chiller preferred colder condenser water that improved its performance With variable-speed condenser pumps, the inlet water temperature to the condenser no longer need be a constant With variable flow through the condenser, the control procedure now is to maintain the heat balance in the condenser like any other heat exchanger The variable-speed pump for the electric machine is controlled by the lift pressure of the chiller, while the absorption machine is controlled by leaving water temperature and minimum flow If the cooling tower water drops as low as 60 F, it may be necessary to reset

the cooling tower sump to a higher temperature for the absorption machine Use of any of these procedures should be approved by the chiller manufacturer under consideration Chiller manufacturers are evaluating many different effects that variable flow through the condensers have on their equipment It is obvious from the preceding examples that the optimal pumping arrangement for a specific installation requires analysis of several different pumping arrangements
1162 Avoiding ice in cooling towers
Ice in certain forms and quantities can be disastrous to cooling tower performance and to its structural integrity Some ice is acceptable in a cooling tower that is designed for operation in freezing climates Heavier amounts of ice that impair the cooling tower s performance or jeopardize the tower structure must be avoided Ice formation varies directly with the amount of air flowing and indirectly with the amount of water flowing through the tower Therefore, pumps and pumping rates can be used to help control ice formation in a tower Constant flow in a tower is obviously important in freezing weather The primary-secondary pumping of Fig 117 maintains a steady flow of water over the tower, regardless of the flow through the equipment using cooling tower water The bypass valve that is used to eliminate flow from the tower should be a two-position valve for most towers and not be throttling, where the flow rate over the tower is reduced from the design rate Ice control techniques vary between cooling tower manufacturers The recommendations of the manufacturer whose tower is under consideration should be the basis of design for the cooling tower pumping system
