Increase the size of distribution piping, or add parallel pipes. The wider a pipe's diameter the less energy is required to move water or air through it. During renovation or expansion, consider increasing the size of distribution piping, or add parallel pipes to double the cross sectional area of the flow path.
Insulate pipes Insulate exposed, hot-water, steam and chilled-water distribution piping where feasible.
Select piping insulation based on both minimum and maximum temperatures. Insulation designed only for high temperature piping (high R-value material) contains no vapor barrier, making it unsuitable for piping that also carries chilled water. Moisture building up in insulation destroys its insulating properties and can damage pipes.
Trim the pump impeller in the cooling plant's distribution system. Trim the pump impeller to deliver the specified gallons per minute per ton of water through the cooling plant's distribution system.
Use pumps to reduce pressure losses in the distribution system of the cooling plant. Use pumps to reduce pressure losses in the distribution system of the cooling plant. Eliminate unnecessary valves and other flow restrictors. Also open the balancing valves at the pump.
