Abstract

An analytical model of a parallel chilled water pump set was established in this study. The bypass-loop adjustment characteristic was found to be a key component of this model. A pump set consisting of four of the same type of pumps was the focus of this study, and the running characteristics for five types of control strategies were examined in detail: the control strategy of the power frequency pump quantity control, the hybrid control strategy of a single pump of variable frequency combined with power frequency pump quantity control, the control strategy of two pumps of synchronous variable frequencies, the control strategy of three pumps with synchronous variable frequencies, and the control strategy of four pumps with synchronous variable frequencies. These strategies were analyzed under different supply–return water differential pressures. It was proposed that the hybrid control strategy of single pump variable frequency combined with power frequency pump quantity control is most suitable for variable flow to the chilled water system under a low flow ratio or a high supply-return water differential pressure.
