How to solve the freezing problem of closed cooling tower?

        The working fluid of closed cooling tower (water, oil or other liquid) flow in the coil, the coil outer wall spray water parcels, fluid through the wall heat transfer and heat steam, water and air travel saturated, heat is discharged into the atmosphere by the fan, spray water in the circulation process is reduced the temperature of the PVC heat sink, and fresh wind into the formation of Feng Shui flow in the same direction, the coil is mainly depend on the damp heat conduction mode, the scale formation principle of important characteristics is the largest such operation may inhibit the coil wall.

        First, add antifreeze: local minimum ambient dry bulb temperature (temperature) of -10 DEG C or lower than -10 DEG C, should add antifreeze of high content of 20-30%, the actual ice freezing as the criterion, the user can flexibly according to the actual situation.

        Two, stop (not long ago) with cooler water in the dry compressed air, the first closed cooling tower water out, then the compressed air is connected to the exhaust hole filling, then the residual moisture exclusion from the water outlet.

        Three, the use of electric heating treatment: when the ambient temperature is only 0 degrees Celsius, can be considered in the pipeline or circulating water tank with electric heater or other heat source to increase the surface temperature of closed cooling tower, so as to achieve the purpose of anti freezing.
