Precautions For Installation Of Closed Circuit Cooling Towers
The fluid (gas) cooled in the closed cooling tower must be compatible with the cooling coil, otherwise it will lead to corrosion of the coil. For example, the refrigerant ammonia is incompatible with copper pipes, and brine and alkaline water are incompatible with carbon steel pipes and copper pipes. Multiple closed cooling towers (evaporative cooling) can change the number of working towers; for multi-fan closed cooling towers, the number of fans can be changed; the working speed or frequency conversion control of the fans can be changed; the amount of spray water can be changed.
The mass of water vapor contained in each cubic meter of moist air becomes humidity. Water vapor in moist air also fills the entire volume of moist air. So the humidity in the resin is the density of water vapour in moist air. Humidity is the amount of water vapor per unit volume of moist air. At a certain temperature, the humidity of the plump air reaches a higher value and becomes plump humidity. Time and space can only elucidate how much moist air pays attention to water vapour in the hi level, but cannot explain the monotony or wetness and hygroscopicity of moist air. Relative humidity reflects the degree to which the water vapor content is close to plumpness, which is generally called plumpness. Under the constant temperature condition of the resin in the 0-1 design, the smaller the relative humidity value, the more monotonous, and the stronger the hygroscopicity. The higher the relative humidity value, the higher the humidity and the weaker the ability to absorb moisture. Calcium, magnesium ions and carbonic acid exist in the water after the closed cooling tower has been in operation for a period of time. Carbonate occurs when heat is transferred across a metal surface. Dissolved oxygen in cooling water can cause metal corrosion, rust, scaling, and blockage of pipes, resulting in decreased heat exchange and cooling tower failure. It is even necessary to spray cooling water outside the shell; the accumulation of impurities such as scaling will consume power, then increase the working cost, and at the same time will corrode the inner wall of the control and shorten the life of the control; the water circulation cooling system of the closed cooling tower is easy to enter Dust and debris. When the cooling water circulates in the circulation system, it will breed many microorganisms and deposits, which will seriously reduce the cooling effect and affect the normal operation; the impurities in the circulating water will cause the packing to be blocked and affect the equipment performance of the system.
