Circulating water system of central air-conditioner of clean tablet production workshop
The object of technology improvement is the circulating water system of the central air-conditioner of the clean tablet production workshop, including two 1,060,000kcal/h chillers and one 1,510,000kcal/h chiller. After system optimization and adjustment, six high-efficiency pumps are are used, and the operating mode is unchanged. According to the acceptance results, 665,000KWH power can be saved annually.
