根据《实用供热空调设计手册》第26.10.5-4条规定，冷却塔的补水量

According to Article 26.10.5-4 of the "Practical Heating and Air Conditioning Design Manual", the water replenishment of the cooling tower includes wind drifting loss, evaporation loss, blowdown loss and leakage loss. Generally, 1% to 2% of the cooling water is used as water replenishment the amount. For systems without a water collection tank, water should be replenished at the cooling tower chassis, and for systems with a water collection tank, water should be replenished at the water collection tank. Therefore, the amount of water supplied to the cooling tower is 71.64 × 1% = 0.71m³ / h, and the amount of water supplied to the cooling tower is 71.64 + 0.72 = 72.36m³ / h.

According to Article 26.10.5-4 of the Practical Heating air conditioning design manual, the rehydration of cooling towers includes wind and ventilation losses, evaporation losses, sewage losses and leakage losses, generally according to the cooling water volume of 1% to 2% as the rehydration. Systems without a water tank should be filled at the undercarriage of the cooling tower, and the system with a water tank should be replenished at the water collection tank. Therefore, the cooling tower tonic water is 71.64 x 1% x 0.71m3/h, the cooling tower water 71.64 x 0.72 x 72.36m3/h.

According to article 26.10.5-4 of practical heating and air conditioning design manual, the make-up water volume of cooling tower includes wind drift loss, evaporation loss, blowdown loss and leakage loss. Generally, the make-up water volume is 1% - 2% of the cooling water volume. For the system without water collecting tank, make-up water shall be provided at the bottom of cooling tower, and for the system with water collecting tank, make-up water shall be provided at the water collecting tank. Therefore, the make-up water volume of cooling tower is 71.64 × 1% = 0.71m3/h, and the water volume of cooling tower is 71.64 + 0.72 = 72.36m3/h.<br>
