Cooling Tower Water Treatment Basics

Cooling tower makeup water intake.

Cooling tower water treatment basics. The cooled water collects in a sump for return to the heat exchangers while the warm air exhaust vents to the atmosphere. The purpose of a cooling tower is to remove the heat generated by an hvac system cooling of compressor refrigerant and heat generated by the compressor itself. The next step is generally running the cooling tower water through some type of. The basics of cooling tower water treatment.

Piping and controls properly engineered condenser chiller and cooling tower piping and controls will improve heat transfer and avoid problems such as air slugging and pumps losing prime. Typically 75 to 80 of heat is removed from water by evaporation process. A key component in cooling towers is the fill material which further. Range or delta t.

Featured cooling water treatment programs scale deposit control for cooling water systems fresh water is being added to the tower to replace water lost through leaks or evaporation. Water is typically the heat transfer medium used to dissipate the heat. Cooling is accomplished through the latent heat of vaporization. The drift eliminators efficiently remove water droplets from the air and return the recovered water to the cooling tower thereby minimizing the loss of cooling tower water.

Cooling tower calculations terminologies. Evaporation of water is responsible for majority of heat rejected from water in cooling tower. Wet bulb temperature is measured by the thermometer which is wrapped in a cloth called soak. Cooling tower is also a water saver equipment where you can save huge amount of water by recycling the water.

A cooling tower uses a combination of heat and mass transfer evaporation to cool the water flowing through the tower. They are located in areas that are situated after the fill and water sprays and just before the area where the air exits the cooling tower see figures 6 and 8. Makeup water or the water replacing bleed and evaporated and leaked water from the. The core of most microbiological treatment programs is feed of an oxidizing biocide to kill organisms before they can settle on condenser tube walls cooling tower fill and other locations.

Wet bulb temperature of a. The function of a cooling tower is to dissipate heat from water cooled refrigeration air conditioning and industrial process systems. For each pound 121 gallons of water that a cooling tower evaporates it removes about 1 000 btu s from the liquid that remains. Multi cell cooling tower configurations that have 100 percent independent systems have limited redundancy.
