CHILLED WATER SYSTEM CONTROLLING METHOD FOR AIR CONDITIONING FACILITY

摘要

PURPOSE:To maintain a load sharing ratio of an absorption refrigerator side high by utilizing waste heat while obtaining necessary refrigerating capacity of an entirety in response to a load change of a cooler. CONSTITUTION:Circulating water amounts to be circulated in absorption refrigerators 1, 1,... are held constant under the control of regulating valves 12, 12, and a feed chilled water temperature is held constant by controllers 8, 8. On the other hand, regarding circulating water to be circulated to compression refrigerators 2, 2,..., a temperature of circulating chilled water from a cooler 4 is measured by circulating water thermometers 11, 11 while maintaining its feed chilled water temperature constant by controllers 9, 9, and when the circulating water temperature becomes a rated value or less due to a load changer of the cooler 4, the circulating water amounts to be circulated to the refrigerators 2, 2 are reduced until the circulating water temperature becomes the rated value.
