How Cooling Towers Work in Commercial HVAC
Cooling towers use specific methods to cool the air in your space. Commercial HVAC systems with cooling towers are more energy efficient than other units, but how do they work? The heat in Atlanta, Georgia needs the most functional system to beat the heat, and cooling towers provide an extra boost.
What are Cooling Towers?
A cooling tower gets rid of unwanted heat from chillers. To do this, water pumps to the top of the tower and moves down flow plates to the basin. Air goes through the plates and over the water, which releases heat via evaporation.
How They Work in Commercial HVAC
The aim of HVAC systems in commercial buildings stems from the need to heat and cool an incredibly large area. Because of this, the size of units must proportionally increase to the space they want to supply high-quality air. Cooling towers fill this gap. They are bigger, sturdier, and take on more work than smaller systems. When used in a commercial HVAC, cooling towers allow for high quality air with far less energy.
Condenser coils are the main focus of cooling towers. Coils generate a lot of heat as the system cycles through its job. When they overheat, problems arise with the air conditioning. Cooling towers move cold water through the warm coils, then into a heat exchanger. A heat exchanger pulls the heat from the water and pushes it back to the coils, which reduces the amount of work for the system on the whole.
Because commercial HVAC units need to cool such large areas, this system provides a smart solution to sudden breakdowns. The work an HVAC unit does to cool commercial spaces far exceeds that of a residential unit, so cooling towers provide stability for the unit. Cooling towers take away some of the pressure on the HVAC system, which lessens the chance of a breakdown.
Proper Maintenance
Because cooling towers are their own beast in terms of cooling technology, they require specific kinds of maintenance. Here are some tips for cooling tower maintenance.
Clean thoroughly. Water pools for long periods of time in a cooling tower, which presents the potential for bacterial growth. Properly disinfect and maintain the interior of the cooling tower at least two times a year to prevent harmful bacteria from forming.
Clean scale deposits. Minerals present in evaporated water stick to cooling towers, which decreases the efficiency of the system. Limescale buildup needs to be removed a few times a year for a functional cooling tower.
Treat the water. Water quality plays a large part in the functionality of cooling towers. System breakdowns occur more often when your water isn’t top quality. Water treatments ensure your water is the highest quality and does not damage your cooling tower.
