Low delta T and low operation efficiency problems, especially in the part loads, are widely experienced by variable flow chilled water distribution systems in today. This paper analyzes the problems cited above and their causes in the typical primary-secondary pumping distribution system. It recommends all-variable speed primary-booster pumping distribution chilled water system which can resolve these problems but has other advantages.
