ASHRAE ST-16-018 - A SIMULATION-BASED STUDY ON DIFFERENT CONTROL STRATEGIES FOR VARIABLE-SPEED PUMPS IN DISTRIBUTED GROUND-SOURCE HEAT PUMP SYSTEMS Organization: ASHRAE
Date: 2016-01-01
Description: These systems circulate water or an anti-freeze solution through multiple heat pump units via a central pumping system, which usually uses variable-speed pumps. Variablespeed pumps have potential to significantly reduce pumping energy use; however, the energy savings in reality could be far lower than its potential due to improper pumping system designandcontrols.
