QUEBEC PROCESSOR GETS 'AIR BLAST' ENERGY AND WATER SAVINGS

摘要

A major plastics processor in Quebec had to satisfy a temperature requirement within the range of 7° to 25°C with chilled water cooling. Looking to trim energy costs, they determined that most of the load could successfully operate at higher supply temperatures, which would allow the majority of the load to be satisfied by ambient-produced cooling rather than high horsepower mechanical cooling. As a result, they calculated that only 22 per cent of the load would require a chiller supplying mechanical cooling at 7°C, while the balance—78 per cent—could be satisfied with cooling at 30° to 35°C.
