If you’re asking yourself, “Is my air cooler noisy?” it’s time to stop and think about the design and operation of your cooling unit. Usually, the larger the holes in the cooling unit, the quieter it will be. But this depends on the type of cooler you have. To reduce noise, you should insulate the cooling unit properly and use the fan-only setting. You should also consider turning off oscillation features if your cooling unit has them.
Normal clicking
If you’ve recently had your AC unit replaced, you’ve likely noticed that it is making a clicking noise. While this is a normal occurrence, it is also an indicator that something is wrong. It can be caused by a number of factors, including loose components or refrigerant piping. In any case, the noise can be problematic, and you should seek assistance from a trained HVAC professional if you hear it regularly.
If you’re unsure what is causing the noise, take a look at the inside of your air cooler. Look for any obstructions on the fan’s blades. These may prevent the fan from spinning freely. If you notice bent fan blades, you may need to contact a professional to have them replaced. Another common cause of clicking noises is electrical problems. Be sure to follow safety instructions whenever dealing with electrical components.
Normal pulsating
If you have a pulsating noise coming from your air cooler, you are probably experiencing a problem with the cooling system. These types of noises can be caused by a number of different issues. Sometimes the noise will stop and start when you open and close the cover. If you cannot figure out what’s causing the noise, you should call an HVAC technician. Here are some of the most common causes of pulsating noise in air coolers.
Pulsating noises are a sign that the unit has a problem and needs repair. While minor pulsating noises are harmless, a loud pulsating noise is a sign that something is wrong. If you notice a loud pulsating noise, there is a good chance that the panel has a loose component or is vibrating. The common components that are at fault are the fan motor, the fan blade, and the coil fan. If the noise continues, you may have a serious problem.
Signs of trouble
If your cooling system isn’t generating cold air, you may be experiencing trouble. If your thermostat is off by 10 degrees, the problem is probably with your thermostat. If you can hear a loud noise or see leakage around the HVAC system, it’s possible that something is wrong with the cooling system. You should check the water pump and the tubing for clogs and debris. If you notice vibration in the area of the cooler’s fan blades, the problem is most likely with the fan.
If you smell musty air coming from the air cooler, you may have a water problem. If this happens, the evaporative pads have become saturated with water, scale, and debris. Replace the evaporative pads, if necessary. If you notice a strange smell coming from the cooling system, this could be a sign of mold or mildew growth. If you notice any of these signs, contact a Wagner technician immediately.
Damping techniques
Among the methods of controlling noise, damping is one of the most effective. Damping works by converting vibrational energy into heat and eliminating it through friction. As the damping effect increases, the resonant frequency of the cooling system falls. The noise produced by this vibration is reduced as damping reduces its travel throughout the structure. This technique is particularly useful in cooling systems. Its applications are extensive, and it can be applied to various types of equipment.
One of the most effective techniques of air cooler noise control is the use of constrained layer damping. It consists of sandwiching a layer of proprietary high damping material between two stiff pieces of metal. The damping material then converts vibration energy into heat, and the constrained layer technique dissipates the most amount of vibration energy. The resulting laminated sound deadened panel is relatively lightweight and doesn’t add as much weight to the structure as the traditional extensional technique does. However, its additional weight may have an effect on performance.
