Cooling tower installation and operation
Site selection
The cooling tower should be installed on the roof or air place, avoid installed in the fire tunnel or next to. easy reflection volume wall.
Avoid installed in soot and dust.Also not suitable fora corrosive gas place , such as the chimney side, hot springs area.
The boiler room, kitchen and other hot places should be far away from Cooling tower and obstacle maintain an air inlet of the cooling tower and an obstacle high ½?
When two cooling tower working together,air inlet face should keep the shortest dist-ance for the cooling air inlet height ½, the non-wind inlet surface should retain the maintenance space and attention to space reserved piping.
When the screw should be tied. Placing base, equipment can not tilt, In order not to affect the cooling effect.Afer the cooling tower installed , whether the tools or other objects placed inside or exhaust outlet should be checkCooling tower base desire to add a shock absorber, between a cooling tower support feet and shock absorbers must be installed integral suspension frame, in order to avoid the damage of cooling tower caused by the uneven stress.
When water supply below the cooling tower or water pressure not enough , shall be provided with another pumps or install an other high make-up water tank for filling water.
Winter shutdown should be attention of antifreeze, make the routine checking of the equipment befor next time
Cooling water management
Antifreezing measures
When the device is operating at low temperature shutdown or climate conditions, you must take measures appropriate. Recommendations are as follows:
The simplest way is adding antifreeze to prevent heat exchange coil freezing .
An electric heater arranged when auxiliary antifreeze to keep the circulating water above 7 ?
That stop running can choose to evacuate fluid inside the coil, the compressed air auxiliary emission.

Approximate empirical formulas
Ps: Latent heat of vaporization of water refers to the numerical local atmospheric pressure -- not standard atmospheric pressure, the customer can approximate value 600.
