1. Cooling tower is also called cooling tower, cooling tower and cold water tower. Products are divided into circular counter-flow cooling tower, square counter-flow cooling tower, square cross-flow cooling tower, filler-free spray cooling tower, concrete steel cooling tower and large FRP cooling tower. Waste heat generated in industrial production or refrigeration process is generally taken away by cooling water.

Second, the cooling towers on high floors are mostly used by refrigeration units. The indoor heat is brought to the circulating water of the cooling tower by refrigerant, and then the heat of the circulating water of the cooling tower is discharged into the air. One of the ways of heat exchange between water and air in cooling tower is that the air flowing over the water surface directly contacts with water, and the heat in water is transferred to the air through contact heat transfer and evaporation heat dissipation.
