Improving Chiller Efficiency with the Help of Automatic Tube Cleaning Systems


There are likely higher chances that you are aware of the fact that the HVAC systems out there are usually the largest energy consumers at any facility during the cooling season. These advanced HVAC systems are responsible for burning around 30 to 40 percent of the overall energy consumption of any building. In addition to this, you must also be aware of the fact that the Department of Energy claims that most of the chiller units are expending over 30 percent or more energy than actually required. This happens due to several operational inefficiencies and various other reasons.
Though you might have taken up some individual steps towards optimizing the overall cooling efficiency of the chiller unit –right from sealing the envelope of the building to making use of a proper building energy management system, performing chiller water resets, cleaning the chiller’s condenser tubes frequently, and so more; still you might not be able to bring about relevant energy efficiency.
As such, you must be aware that there are other methods of further increasing the overall energy efficiency of the chiller unit in your building or chiller-water plant. One such method is making use of a continuous, automated chiller tube cleaning unit referred to as the ATCS (Automatic Tube Cleaning System).
Most of the times, fouled condenser tubes of the chiller unit are the main culprits of the overall energy losses in the chiller unit. Moreover, it is not uncommon to come across chillers that appear to be working efficiently but with elevated fouling factors. This can cause the power consumption of the compressor unit to increase by as much as 15 percent.
How Continuous ATCS Improves Chiller Efficiency?
Automatic Tube Cleaning Systems (ATCS) units are installed at clean-tube conditions and function by passing sponge balls periodically through the condenser tubes of the chiller unit. Usually, the injection cycles for these sponge balls occurs around 20 minutes. The overall injection & collection process of the foulants is fully automated and is controlled with the help of a single programmable logic controller, without any human intervention. The controller is also able to provide proper alarm & monitoring functions towards ensuring that the system is operating optimally in a continuous fashion. ATCS technology can thus, help in optimizing the overall energy efficiency of the chiller units in the chiller water plants and can offer substantial power savings.

How Hazardous the use of Chemicals is for the Chiller & the Cooling tower?

Cooling towers use evaporation of water to remove excess heat and cool the working fluid. Cooling towers provide low water temperature with air-cooling or another dry rejection device. It is not only cost effective but an energy efficient system for cooling. There are many types of cooling towers like counter flow, cross flow and hyperbolic. A chiller is normally a machine that helps to remove heat from the liquid through absorption or vapor compression. The liquid normally circulates through the heat to cool the particular equipment. Chillers and cooling towers are rated on the basis of the range and approach. This also depends on different types of temperature. There are many hazardous chemicals that are used in chillers and cooling towers. Cooling tower uses Acid that can lead to oxidization or scaling. The sulfuric acid introduces sulfate ions (SO4-2) to the normal water. Eventually, this may also lead to calcium sulfat...

Automatic Tube Cleaning System –Boost Your HVAC Efficiency at Minimal Costs

Most of the times, scaling and micro-fouling are regarded as major problems in the condenser tubes & heat exchangers. This tends to be ultimately lowering the overall system performance, output, and service life of the given system. The utilization of the advanced ATCS-HVAC systems thus stands vital –not only for ensuring comfort cooling in commercial or residential buildings, but also for ensuring top-class efficiency in a wide range of industrial applications including chip manufacturing, cold storage, and so more. The only problem that might occur is during the utilization of recycled water in the open cooling tower system. For overcoming such a situation, the automatic brushing system gets installed that helps in setting up a continuous, automatic cleaning process in motion. An advanced ATCS-HVAC system helps in bringing a permanent solution for intense fouling in the industrial chiller heat exchangers & condenser tubes. The ATCS ( Automatic Tube Cleaning Systems) are k...

Bring About Top-Notch Hotel Energy Efficiency with ATCS

Ever wondered what those big noisy boys (usually found in the basement area) meant for? These are the units that could run up your overall electricity bill up to 70 percent when you are running a hotel. These are the chiller units and these are used for generating cold water (4 to 7 Degree Celsius) that gets circulated to the guests & function rooms in the hotel building. These chiller units are used for cooling down the spaces as per the required comforting temperature in any hotel building. The cooling system of your hotel building is made out of the same component like any refrigerant. The refrigerant gets evaporated in the evaporator and heat gets absorbed. This evaporated heat then condenses in the condenser unit & helps in releasing heat from the hotel building & different units. The condenser unit needs to be cooled, probably brought about by water that keeps circulating over the cooling tower. Over the passage of time, mineral deposits & pollutants fro...
