Proper control of HVAC variable speed pumps.

Type of article: Article

Summary

The variable speed pump has reduced the over-pressuring of water systems and reduced pump maintenance caused by the excessive radial thrust often found in constant speed pumps. Often, energy consumption by variable speed pumps is a fraction of that of constant speed pumps. However, most of these advantages are lost when proper speed control is not maintained in variable speed pumping systems. The authors review six parameters that have proved to be indispensable in achieving a successful and efficient HVAC variable speed pumping system as well as location of the differential pressure transmitter, use of valve position to control pump speed, and rate of response.
