What is the maintenance of cooling tower?
Keep the Tubes Clean All units experience build-up, and Hamon can help you decide on the maintenance schedule which works best for your company. Cleaning tubes regularly is the most efficient way to remove debris. Chiller tubes play a vital role in overall cooling tower maintenance.
What happens when a cooling tower fails?
A cooling tower fails because its evaporative mechanism breaks down. The evaporative water flow begins to warm. As a knock-on effect, the air flowing through the structure warms too. Odds are the heat exchanger isn’t working properly.
What are the major components in a cooling tower?
The major cooling tower components include Cold Water Basin, Cooling Tower Structure, Fills, Drift eliminators, Cooling Tower Fans, Water Distribution Piping’s, Fan Deck & Fan cylinder, Cooling Tower Louvers, Gear box, Drive shafts & Mechanical Equipment Support, Valves, Nozzles and Electrical & Instrumentation systems …
What do you check in a cooling tower?
Check fan motor for proper rotation Check general condition of the fan Check & unplug fan drain holes (hollow fan blades) Check fan for uniform pitch Check fan for rotation without obstruction Check & recoat steel shafts with RUST VETO® *Tension on new belts must be readjusted after the first 24 hours of operation and …
How do you troubleshoot a cooling tower?
Ensure that the float is located such that the water level remains within specifications. Be sure that there are no leaks in the cooling tower system. Verify that the chemical feed pump is properly primed. Adjust the chemical feed pump settings until the water conductivity is within the acceptable range.
What is the possible causes of lack of cooling in cooling tower?
Corrosion is caused by the combination and reaction of air, sodium, and other chemical components found in the water supply. This chemical reaction causes destruction or loss of the metal within the cooling tower.
What is cooling tower fill material?
What is a Cooling tower fill material? Fill, or wet deck or surface, is a medium used in cooling towers to increase the surface area of the tower. This enlarged surface area allows for utmost contact between the air and the water flow, which as a result allowing greater evaporation rates.
How does a cooling tower work HVAC?
Cooling towers use evaporation to release waste heat from an HVAC system. In an open tower, hot water from the condenser is slowed down and spread out over the fill. Some of the hot water is evaporated in the fill area, or over the closed-circuit tubes, which cools the water.
When should cooling tower fill be replaced?
About cooling tower fill replacement frequency It also advisable to replace your cooling tower fills every 10-14 years to maintain the original output. You may not be aware that your cooling tower fills need immediate replacement.
How do you inspect a cooling tower?
Check the assembled joints of a fiberglass or plastic tower to be sure that hardware is tight and in good condition. Look for evidence of tearing or cracking in the structure. Save time and effort with the MarleyInspections cooling tower inspections app, now available on iOS. Download it here!
How often should a cooling tower be inspected?
A building owner should ensure a regular daily/weekly and monthly preventative maintenance schedule is applied for their cooling towers and ancillary equipment throughout the year to help and ensure: The risk of Legionella is managed/reduced.
What causes foaming in cooling towers?
Here’s why: Cascading water, the continuous recycling of contaminants, and a high concentration of foam stabilizers can cause foam to overflow the tower sump, blow off the towers, or even cause an airlock in the water pumps.
What is TDS cooling tower?
The TDS concentration of cooling tower water and the pH values depend on its original sources and on the cycle number of circulations inside the building. The TDS values change from 300 to 1,200 ppm.
Does cooling tower have refrigerant?
A condenser which is located inside a cooling tower where it is cooled is also known as an evaporative condenser. In this case, the refrigerant in the condenser is directly cooled by the water in the tower. The same process happen in that the water from the tower is pumped and recirculated.
How much water does a BAC cooling tower hold?
The volume of water varies from one cooling tower to another, but I could estimate the flowrate. For a 150 Ton Cooling tower, which a typical Condensor water temperature difference of 5 degrees, the flowrate is estimated to be ((150*3.517)/5)/4.19 = 25.18 liters/second.
How do cooling towers work in commercial settings?
What is the difference between cooling tower and condenser?
Cooling Tower&Chiller Major Components. Cooling towers major components include the pumps and basin.
What are the function of the cooling towers?
Natural draft — Utilizes buoyancy via a tall chimney.
