The location and operation parameters of the heat pump are optimized. Effects of heat pump on retroﬁt cost and CO reduction of HEN are analyzed. Characteristic of heat pump on CO emission reduction in HEN retroﬁt is discussed. CO emission reduction of a heat pump integrated in HEN is not always positive. ar ti c l e i nf o ab stra ct Article history: Integrating a heat pump into a heat exchanger network (HEN) can effectively recover the low-grade heat Received 1 January 2015 and reduce energy consumption. In this paper, a multi-objective optimization model on a HEN retroﬁt Received in revised form 4 May 2015 with a heat pump is proposed, with the goals of
