Status:
Active
Publisher:
ASHRAE
Addresses the application requirements for utilising blending pumps to increase supply water temperatures in individual buildings or zones. For pumps, it makes recommendations relative to the flow rate, head, impeller characteristics, speed, and best efficiency point. Also for pumps, it addresses motor selection, variable-frequency drive (VFD) selection, and control requirements. For system load control consideration, it addresses the need to increase supply temperatures on some existing systems, the effect of excess pressure in the primary systems, and the benefits of blending pumps when used in conjunction with existing constant-flow hydronic systems.
KEYWORDS: year 1996, water pumps, flow rate, water temperature, variable speed motors, efficiency, energy conservation, pressure difference, comparing, energy consumption, chilled water supply, temperature stratification, water heat storage
