Frequently Asked Questions
COOLING WITH HIGH HEAT DISSIPATION OF THE HEAT THROUGH THE DIRECT EVAPORATION OF THE WATER IN THE HOT AIR, COLD, OR WITH THE DISSIPATION OF HEAT BY MEANS OF THE CONTACT OF THE HOT WATER TO THE FILL?
To the tower you can using the thermal dissipation evaporative order to remove the heat from the water, thus cooling it to a temperature close to the temperature of the wet bulb, so that the pads contact the stuffing to receive the nozzles in the spray of the distribution of warm water in the process, thereby increasing the surface area in contact with the cold air and the hot water in the bathroom cross, taking in the warmth of the water.
And in some of the models, the tower is able to operate without the filling-contact-filling, so that the hot water in the process, you can directly contact with the cold air blowing in from the outside, thus cooling it to a temperature close to the temperature of the dry bulb.
COOLING TOWERS WITH WHICH TO FILL THE CONTACT IS A FILLING?
The filling of the contact, the filling of the cooling tower should be selected according to the temperature, which is typical of the process water to be cooled, so that the PVC can support up to 55°C, and the PP can support up to 85°C
The types are:
-COLOR Block wall), the shape of the wave crossed into the PP, or PVC, resistance to water of up to 120 pages per minute;
-Bus rapid transit (the Bars in a Drop-Tube) with a tubular design, in PP or PVC, backing water with high levels of suspended solids;
-PUT Blocks (Film), the shape of the bee hive in the vinyl can be applied only to the waters;
RT (Bar Drop, in the form of Lath Triangle) on the PP, or PVC;
-BRR (Bars, Drop, Rectangular, in the shape of the tray) is in NP.
COOLING TOWER FAN, AXIAL FAN OR CENTRIFUGAL FAN?
Axial fans can also be installed in the air inlet on the side of the tower, forced draft, breathe new life into the cool air from the outside to the inside, but they can also be installed on the air outlet on the top of the tower, induced draft, breathing in the hot air from the inside to the outside of the tower, with funding from the air, the landscape, and the discharge of the air in a vertical position, on the way up, being selected for in-76db(A).
The centrifugal fan type sirocco, they are super-low noise and suitable for environments that require a low level of noise, such as hospitals, universities, theaters, cinemas, theaters, among others, will be installed at the air inlet on the side of the tower, forced draft, breathe new life into the cool air from the outside to the inside, with a catchment, and the discharge of the air in the landscape, by being super-silenced on the 72db(A).
COOLING FAN, MAKING THE AREA OF THE AIR SUPPLY TO THE AIR?
The aspiration of this is when the fan pulls the hot air from the inside of the tower is off, tossing it into the air.
Air supply is on when the fan blows the cold air from the outside environment to the inside of the cooling tower.
THE TOWER OF THE COOLING-FLOW AND COUNTER-CURRENT, OR FLOW OF CURRENT IN THE CROSS -?
In the counter-current flow of air is picked up at the entrances to the horizontal on each side of the tower, going vertical in a bottom-up movement to be thrown in by the fan, as the flow of water that is distributed through the nozzles in the top of the tower, and it all flowed down against the power of the air that is coming up.
In the current cross-flow of air is taken into the vertical faces of the sides of the turret back and forth in a straight line across the stream, the water's going down.
COOLING SYSTEM FOR THE DISTRIBUTION OF WATER BY GRAVITY ON THE FREE TO AIR CHANNELS OR DISTRIBUTION SYSTEM OF A WATER PRESSURE BOOSTER AT THE PIPE CLOSED?
The aspiration of this is when the fan pulls the hot air from the inside of the tower is off, tossing it into the air.
Air supply is on when the fan blows the cold air from the outside environment to the inside of the cooling tower.
COOLING TOWER IN AN OPEN-LOOP OR CLOSED-LOOP?
In the process of the cooling tower in an open-loop is by means of a pump for the hot water to the top of the tower, to be delivered through the nozzles, spray heads, forming water droplets. These droplets fall to fill in the contact, allowing for a greater contact of the hot water and the cold air in the contrafluxo. So, a cooling tower in an open-loop carries the heat transfer from the air by means of evaporation of the water.
The cooling tower is removed or deployed on-current can be produced in a closed circuit, ideal for industrial process in which it is not allowed to occur in the contact of the water with the external environment, due to the need for the conservation of its features, by using a coil of zinc-plated steel, fire steel or stainless steel for the movement, only of the water. Because it has a small water crossings, which are difficult to clean, it can't get dirty water in ppm, so as not to clog up the distribution system, as a kind of tower, and its main advantage is the preservation of the quality of the water, and freedom from inclusions, or on any type of outside contamination, reducing significantly the consumption of water of a replacement, or evaporation from, and relying on the centrifugal pumps to recirculate the water, successively re-used.
COOLING TOWER MAINTENANCE, PREVENTIVE, PREDICTIVE, AND PRESCRIPTIVE OR CORRECTIVE?
The preventive maintenance boils down to predicting the faults that may occur and to mitigate them by means of the presentations delivered on the day-to-day so planned, prepared, and is scheduled to run.
Predictive maintenance comes down to action off on each and every machine, and assessing individually the amount of time that the machine was available for use, by means of the following calculation:
A = [amount of time available / (available time + downtime)] × 100, so that if one machine and present the vacancy rate is far below that of the other, and there should be action.
The maintenance-how about implementing advanced technology in the monitoring of the machines to rise up and cross over the data that generate insight about the possible failure to absorb the system itself, to the tips in order to avoid the errors that may occur.
The corrective maintenance just to fix a process that has been interrupted and has caused delays in production, with many losses on account of the machine is at a standstill.
COOLING TOWER IS IN NEED OF A REVAMP OR A RETROFIT?
Pensions and revamp it to the recovery and restoration of the thermal capacity of the cooling water that had been established in the first place.
Retraining, or retrofitted it is an upgrade to the cooling of the water to increase the heat capacity was originally designed.
COOLING TOWER SHOULD YOU RENT OR BUY?
There are pros and cons that need to be considered in making a decision between renting or buying a cooling tower water system.
The location of a cooling tower is necessary in order to meet the needs of occasional or emergency, using the device only on a seasonal basis, to supply deficiencies in the heat exchange, or when you in any shutdown, then serving as a temporary solution, and optimal use of the limited space on the floor, in addition to the exemption, the costs of maintenance.
With the purchase of a cooling tower is required when a manufacturing process requires that the heat transfer constant, which must be tailored according to the specific requirement of the cooling water from the process, whereas the calculation of the size based on the volume of water in which the equipment will operate temperature: hot or cold as possible, and location to help you evaluate the TBU and the high altitude of the region.
