Energy conservation effect of heat source system for business use by the advanced centrifugal chillers.

Author(s) : UEDA K., HASEGAWA Y., SEKI W., et al.

Summary

The high-performance centrifugal chillers have been effective technology to reduce CO2 gas and save energy by application to the heat source system for the air conditioning since 2000. The chillers have been installed in the latest clean rooms of semiconductor, flat-screen display and high-density storage media plants. The high-performance centrifugal chiller, which is controlled by the inverter and has maximum COP 21.9, has been developed in Japan and it contributes to energy conservation of industrial heat source systems. This report describes that the high-performance centrifugal chillers are extremely effective to reduce energy consumption of heat source systems for air conditioning. 50% of total energy consumption can be reduced by the new planning and operating method in the heat source systems for air conditioning and 60% of annual energy consumption can be reduced in the centrifugal chillers, the heat source machines. The high-performance data of centrifugal chillers are based on actual test measurements. This report also describes new performance-estimation method of cooling towers, which is indispensable for new planning and operating method, and it is verified by the comparison to the actual measurement data of a simple heat source system.
