Road 20 flows to tower outer heat-exchanger 12, triple valve 11 is imported through pipeline 22 after the outflow of tower outer heat-exchanger 12, finally by threeway
Valve 11 flows back to pumping plant, forms circulation；When triple valve 11 is in full off state, pipeline 21 connects with triple valve, pipeline 22 and threeway
The connection cut-out of valve, coolant directly flow to triple valve by pipeline 21, finally flow back to pumping plant.Tower outer heat-exchanger 12, pipeline
20th, 22 are referred to as outer bypass, and wherein tower outer heat-exchanger 12 is located at outside tower, and pipeline 20,22 runs through tower, outer to bypass system
Heat is taken out of outside tower, then transfers heat to external environment by tower outer heat-exchanger 12；Outer bypass coolant rate passes through
The regulation of triple valve 11 realizes that triple valve standard-sized sheet, coolant all bypasses outside inflow, and now system radiating ability is most strong, triple valve
Fully closed, it is 0 to flow into outer bypass coolant rate, and system radiating ability is most weak.
The tower circulate in the wind road figure being illustrated in figure 2 in bottom of towe cooling system, mainly by tower inside heat exchanger 3,4, ventilation
