4 General

4.1 The cooling tower should be newly constructed or renovated in accordance with the requirements of GB/T 7190.1 and GB/T 7190.2, and the cooling tower performance should be tested after completion or renovation.

Test, if the test results do not meet the requirements, rectification should be carried out.

4.2 Cooling tower water replenishment should preferably use recycled water, regenerated water, rainwater, desalinated seawater and other unconventional water sources. For places with clear water replenishment requirements, except.

4.3 The cooling tower should be inspected on site regularly, and any problems such as splashing water, abnormal water drifting, leakage and overflow should be dealt with and recorded in a timely manner.

4.4 Measuring, monitoring and other instruments should be inspected, calibrated and maintained regularly.

4.5 Water treatment technologies and water treatment chemicals that are highly water-saving, environmentally friendly and safe to use should be selected.

4.6 In order to reduce the consumption of circulating cooling water, indirect cooling towers, dry-wet cooling towers, and condensing mist-eliminating water-saving cooling towers should be used first.

4.7 A sound cooling tower operation management system, water-saving reward system, and inspection and maintenance instructions for cooling tower equipment should be established.
