Understanding the function and friction loss of each part of the piping system is important to the layout and successful
installation of a chilled liquid solution system.

The circulation pump is the key performer in the piping system. The pump must circulate the liquid solution through th
heat exchanger and piping system to the air handlers. Pumps are designed to deliver a flow rate measured in gallons
per minute(GPM). The pump must be able to overcome the resistance to flow (pressure drop) imposed by the chiller
components, piping system and air handlers while maintain the necessary flow rates in gallons per minute. Pump
capacities in gallons per minute and pressure drop (feet of head) are listed in table 1.

Motorized Control Valve:
The fan coil's motorized valve controls the flow of
liquid solution to the system coil. Each fan coil in the system should have a motorize
