A large direct industrial refrigeration system was installed to reduce energy consumption in a chemical process plant. Electrical energy was saved by eliminating an intermediate cooling circuit including chilled liquid heat exchangers and glycol circulating pumps. A benefit of the system was increased production capacity by improving evaporator heat transfer, which reduced batch cycle time. This paper discusses system design, start-up and operating experience, and energy savings.
