Composite Piping Layout and Design
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.

Pump
An adjustable valve must be used to throttle the discharge liquid solution flow rate to appropriate levels based
The circulation pump is the key performer in the piping system. The pump must circulate the liquid solution through the
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

Piping resistance or pressure drop is measured in feet of head. A foot of head is the amount of pressure drop imposed
in lifting liquid solution one foot. Pumps in the Multiaqua system are designed to move rated liquid solution flow (see
