In commercial buildings like malls or commercial complexes, chillers are usually the single largest consumer of energy. Meaning they're the reason HVAC systems are infamous for huge electricity bills and energy wastage. But with energy prices continuing to increase, chillers are now looked at as a potential source of significant energy savings. And the only way to achieve this goal is through preventive maintenance, which means keeping the chillers or condenser tubes free of fouling. Hence, HVAC operators have to keep everything at optimum condition, which also means keeping a daily log to the weekly, monthly and annual operational reviews. But how regular tube cleaning and keeping the record of it will help them yield optimum efficiency of the chillers.

Automatic Condenser Cleaning System for Chillers

Most modern technology used today for round-the-clock cleaning of Chiller tubes is Automatic Tube Cleaning System, this automatic method of cleaning heat exchanger tubes occurs while the equipment remains in operation and in full production. This is an online method that infuses some slightly oversized elastomer balls periodically to the Condenser tubes and keeps the tubes free of fouling 24×7. A strainer or ball collector is installed at the water piping exiting the condenser that collects the balls for re-circulation in the system. There is absolutely no need for system shutdown for descaling and as a result, Chiller operates at top performance and efficiency.

Different Types Of Cooling Towers: Know Which One Is The Right Cooling Technology For You

Commercial buildings and Industrial machinery generate large amounts of heat while processing. And to stay operational, they need continuous heat transfer which is only possible through a heat exchange process. That is where the cooling technology used in cooling towers comes in handy.

Despite being a technology of the 20th century, knowledge about cooling towers is limited. Some people even believed them to be a source of air pollution. Contrary to popular belief, the only thing they release to the atmosphere is vaporous water. Cooling towers help eliminate excess heat used in industrial operations and transfer it out into the atmosphere.

There are different types of cooling technologies available in the market for achieving this process. However, the function remains the same, which is to transfer heat from the system or a facility to the atmosphere via evaporation. These types of cooling towers are defined by how they use water or air to perform heat transfer. Each of these cooling towers is applicable for certain load configuration, which helps tower operators choose the best option available.

These types include mechanical-draft and natural-draft hyperbolic cooling towers:  

Natural-draft cooling towers: With hyperbole shaped cooling towers, this cooling technology utilizes shape and pressure to move up the air naturally. Typically located outside the buildings, these cooling towers induce a pressure difference between heated air and the surrounding air. Due to this pressure difference, air enters into the cooling tower while the water doesn’t come into contact with the air, which is only possible with a heat exchanger. Read more

What Are The Most Neglected Components in HVAC Systems?

There are many components in HVAC systems that make the process of heat exchange more efficient. However, each of them has some advantages and even disadvantages. But the most significant components of any HVAC system are chillers and cooling towers. Chillers generate chilled water used to keep the people inside at a comfortable temperature. Chillers move the unwanted heat between the evaporator and the condenser by sending the chilled water around the building to collect the unwanted heat and bring it back to the evaporator to be cooled down. The refrigerant collects this heat and moves it to the cooling towers to send it into the atmosphere.

However, it makes chillers and cooling towers more prone to scaling and fouling, which can lead to unwanted repair and system failure. Therefore, the HVAC industry has to take solid steps for optimizing the efficiency of your cooling systems. You have to utilize a water filtration system and an online condenser tube cleaning system in India to ensure smooth cooling operations. But when looking for energy-saving opportunities in HVAC systems, you must look deeper than the chiller itself.

Cooling towers consist of several parts and power transmission technologies, such as gear drive, belt drive, direct drive, and electronically commutated (EC) drive. Therefore, proper knowledge is beneficial to strike an appropriate balance of initial cost versus operating costs. However, the essential component in any cooling tower is the fill media, also known as packing, filling or baffles.

It helps increase the surface area of water cooling towers to put as much water surface area in contact with as much air as possible for as long as possible to achieve a cooling effect. The extended surface area enables the optimum level of contact between the air and the water, which ensures greater evaporation rates. It further reduces the load on the water supply network and the operating cost while making full use of water resources.

Types of fills in Cooling Towers:

Splash Fill: Splash fills consist of many layers of slats or bars in which water cooling towers break down into tiny particles. These small particles increase the contact between the water, which accelerates the rate of evaporation and cooling.

Splash media is made of PVC, allowing a higher rate of heat transfer. Splash fill is mostly used in industries that produce excess filthy water because it converts water into smaller droplets and will separate the dirt and debris from it.

Film Fill: Film fill is constructed by placing thin PVC sheets together with minimum gaps. These PVC sheets create a big surface area in the water cooling towers, which allows the circulation of hot air and comes in contact with the film of material. This increases the rate of heat transfer while cooling down the water and collecting the debris within it. The film fill is perfect for regular water that is good enough for human consumption.

How to choose the right fill for your water cooling tower:

Both film fill and Splash fill are efficient in facilitating the cooling and evaporation within a cooling tower. However, each of these fills has its own advantages and disadvantages too. Film fill generates a much bigger surface area, which ensures better heat transfer. On the other hand, it has a shorter lifespan due to constantly being exposed to high temperatures.

A splash fill is right for you if you operate a cooling tower that uses a low-quality water resource with a higher amount of solids. The metal grills in splash fill make it much more resilient in high temperatures but more exposed to corrosion and damage.

Need for a fill replacement in water cooling tower:

Every component in cooling towers starts to wear out with time without proper maintenance, and the same is in the case of fills. To ensure that your cooling towers are working efficiently, all you have to do is keep a regular check, which will help you replace your cooling tower fills in time.

Make sure to look for:

● Calcium build-up

● Warped or sagging fill packs

● Increased consumption of energy

● Uneven distribution of water

● Damaged support grids

Conclusion

Damaged or neglected components can greatly reduce the rate of heat transfer in the HVAC system. By timely performing maintenance routines, you can increase the efficiency and its heat transfer performance. It will also increase the lifespan of the cooling tower system and its components. Eventually, replacing cooling tower fill will help you save a lot in utility bills and utilizing an online tube cleaning system will reduce your maintenance cost and give you maximum output from your chillers.
