Performance of DamaTajhiz fiberglass cubic cooling tower DTC-CO 350

  • With the COUNTER FLOW airflow, some of the water in the cubic fiberglass cooling tower of the 350-ton refrigeration equipment is evaporated to cool the circulating water. Due to the heat absorption of the evaporation process, the rest of the water returns to the cooling tower (a temperature higher than the WET BULB temperature) environment) which, after collecting in the pan of the cooling tower, is sucked by the water circulation pumps of the tower.
  • In general, the calculation and design of cubic cooling towers have been done based on the inlet water temperature of 95 degrees Fahrenheit, the outlet cold water temperature of 85 degrees Fahrenheit, and the wet air temperature of W.B.T.75°f.
  • The temperature of the water leaving the cooling towers depends on the temperature of the humid air in each place, and the average temperature of the water leaving the cooling tower is about 2.5 to 3 degrees Celsius higher than the temperature of the humid air (wb) of the same place. For example, suppose the maximum humid air temperature in Tehran in summer is equal to 22 degrees Celsius in normal conditions. In that case, the temperature of the water-cooled by the cooling tower is about 25 degrees Celsius.
  • The cubic fiberglass cooling towers are of the suction type (DRAFT INDUCED), and the airflow rotation in the tower is possible in both natural and forced ways. The forced suction is done by the AXIAL fan located at the top of the tower.

  • The fan stack or fan oven is made of P.R.F. fiberglass fibers with a thickness of 8 mm and includes anti-UV materials resistant to ultraviolet rays. The diameter of the top opening of the fan stack is 235 cm.

electric motor

Electromotors of cubic fiberglass cooling towers (DamaTajhiz) are generally Motogen products and have IP54 sensitivity.
Cubic cooling towers (DamaTajhiz) are standard in terms of noise level, but they are also produced in low-noise and ultra-low-noise types, which are different from other towers in terms of size and price.
The system's fan is suction type, axial or axial. It has aluminum material, an aerodynamic section, 6 blades, low noise Super model, with a width of each blade of 25 cm, and the fan angle is set at 16 degrees.
The material of the airfoil propeller is 6-blade adjustable, anti-corrosion, and has static and dynamic balance, which causes smooth movement and long life of the bearings.
The power transmission system to the money belt is also 1 to 4.

Cooling tower packings

  • The packing sheets of the cubic fiberglass cooling towers (DamaTajhiz) are stacked on top of each other in a honeycomb shape, the grooves of the packings are designed in a sinusoidal way, and there is no possibility of clogging them to create a suitable substrate for the formation of a water film and rapid evaporation. And more contact surface with air to maximize heat transfer. Packing of cooling towers (equipment) is usually 19-grade film type and made of P.V.C. material with a special antibacterial coating with pharmaceutical grade (with F.D.A. approval), and 400-micron thickness or splash packing or random splash etc., made of first-grade P.P. material with grade It is medicinal and antibacterial with a thickness of 500 microns, the height of the packing media arrangement with a unique surface is 170 square meters per cubic meter, which is offered according to the choice and order of the respected buyer.
  • At the request of the respected customers, drip catcher parts are also installed on the packing of the cooling tower to prevent the water droplets from coming out by the fan and to reduce the water particle ejection to less than 0.02 of the circulating water in the cooling tower, which is the minimum allowed amount. Determined by the U.S. Environmental Protection Agency is less.

cooling tower water distribution system

In the cooling tower (DamaTajhiz), the incoming water enters the water distribution nozzles through the central pipe or pipes made of polyethylene or P.V.C. It is sprayed on the packings of the tower (choose the nozzles according to the climatic conditions of the region and the different requests of customers).

Supporters

  • The supporting bases of the cooling tower of the thermal equipment up to the DT-175 model are made of fiberglass and are used in higher capacities than hot galvanized supports.
  • Cubic cooling towers in D.T. 50 and higher models are subject to the O.S.H.R. mandatory standard. Hot-dip galvanized ladders are installed to access the mechanical and electrical components of the cubic cooling tower.
  • The supporting chassis of the fan stack is made of galvanized sheet with a thickness of 6 mm, and the protective nets of the fan guard are made of heated iron with plated zinc ranging from 83 to 110 microns. The bases and chassis of the motor holder are also made of hot-dip galvanized angle.
  • The panel holder, cooling tower floor chassis, external supports, and coil holding support on the tower chassis are made of hot galvanized zinc-type iron with a thickness of 150 microns.
  • All the internal support supports, including the drippers and packing supports, are made of fiberglass with the pultruded process of anti-corrosion P.R.F. tensile fibers and with tensile and bending strength 4 times that of iron in one direction.

Eliminator or dropper

P.P. eliminators are installed in the upper part of the nozzle, which is a blade type and reduces the number of water drops to less than 002.0% of the water in the rotation to reduce the number of water droplets drifting from the top of the cooling tower.

Components of the cooling tower fan

  • Fan blade: The fan blade is made of plastic reinforced with glass fibers (fiberglass), which has more chemical and physical stability than aluminum propellers, and due to its polished surface, it has less friction with the surface and minimizes air resistance. Isophthalic resin and high-quality fibers are used in the production of these propellers.
  • Fan handle: This part is the connecting factor of the propeller and the hub, which is made of carbon steel with galvanized plating.
  • Fan hub: It is made of unbreakable cast iron and is in the form of a coupling, which makes it possible to assemble the propeller quickly.
  • Types of bolts and nuts: In producing propellers, dry bolts and nuts are used, which have a lot of resistance. Stainless steel connections are also used if the fan is placed in acidic and corrosive environments.

Inverter or variable speed cooling tower system

In the case of ordering a cubic cooling tower, by installing an inverter system in the cooling tower's electrical panel, the speed of the fan and motor can be changed to accurately control the temperature of the cooling tower's outlet water. (If the inverter system is ordered, a separate switchboard must be installed for the tower)
The command to change the frequency of the inverter is operated by a sensor that operates in a specified temperature range. The operation of inverters is in the form of frequency changes. As a result, the power of the electric motor remains constant. In cases where the output water temperature is not very sensitive, the thermostat controls the output water temperature by turning the engine off and on.

Estimating the required space for installing a cooling tower

  • All cooling towers must be installed outdoors and exposed to the direct flow of free air. There should always be enough space around the cooling tower without obstructions so that enough fresh air can easily be available to the tower.
  • The hot air coming out of the tower must be discharged in such a way that it is not possible to return and recirculate it to the cooling tower because the recirculation of such air in the tower causes the wet bulb temperature to increase and the water at the tower outlet to remain warm. becomes
  • In general, to install towers up to 2.5 meters high for each ton of refrigeration, we need a surface of 0.1 square meters (in construction uses) for every 50 square meters under the building's helpful foundation. Also, in towers with a height of more than 2.5 meters per ton of refrigeration, we need a surface of 0.12 square meters per 50 square meters under the building's helpful foundation.

Transportation and installation of the cooling tower

  • Suppose the diameter of the cubic fiberglass cooling tower you purchased is more than 250 cm. In that case, it is recommended to transport it separately to the project site to prevent damage to the cooling tower during transportation. The final assembly of the cooling towers with a diameter of more than 250 cm will be done at the project site by paying a separate fee.
  • If it is impossible to transport the cooling tower to the project site or the installation site on the roof, please order the cooling tower separately (DEMONTAGE) at the time of the purchase order.
  • All shipping costs and, if necessary, reassembly of the cooling tower at the installation site are the buyer's responsibility.
