The analysis results of thermal characteris tics of the cooling tow er running in w inter ind icated that one heat exchanger should w ork in conjunction w ith wt o cooling tow ers and wt o cooling water circulation pumps to reach a cooling capacity comparable to that of onew ater chiller. Comparing w ith the w ater ch iller, cooling tow er could reduce energy consumption by more than 60% in w inter, i. e. 2. 5 m illion kWh electric pow er or 2. 07 m illion RMB Yuan per year.
