Design of on-line thermal performance monitor and system for cooling towers
Abstract: As the most cooling towers are monitored by discrete instruments which is inefficient， uneconomical and hysteretic， an on-line thermal performance monitor and system was designed to measure the operating and environmental parameters of cooling tower automatically. The Merkel theory was used to calculate the thermal performance in the system. And the monitoring results and fault of the system was sent by a message via 3G module. The experimental result indicates that the system is precise enough and efficient for cooling tower monitoring and in favor of improving the energy-efficiency of cooling towers.
