Things You Need to Know Before Buying Water-Cooled Chillers in Bangladesh

Water-cooled chillers are the recommended option for cooling large commercial spaces because of their effectiveness in handling high cooling demands. In contrast to conventional air conditioning systems, which employ coils filled with refrigerant, water-cooled chillers absorb and distribute heat by moving cold water throughout the building.

This approach, which depends on chillers, pumps, and a well-insulated pipe network, offers dependable and consistent cooling, which makes it perfect for settings with high cooling requirements.

In addition to maintaining a constant temperature, water-cooled chillers have energy-saving benefits. They can cool larger areas with less power consumption, particularly in hot climates, by using water as the cooling medium.

In order to efficiently control heat dissipation, the system also needs parts like cooling towers, which adds to its ability to function well in large environments.

Advantages of Selecting Water-Cooled Chillers

Greater Capacity for Cooling

Water-cooled chillers are ideal for commercial and industrial buildings because they are made to cool large areas and have a larger capacity than many air conditioning systems.

Efficiency of Energy

Generally speaking, water-cooled chillers use less electricity than conventional HVAC systems, making them an energy-efficient option that is particularly advantageous for lowering long-term operating expenses.

Improved Management in Big Areas

Water-cooled chillers are skilled at controlling the climate of large areas by supplying constant temperatures and humidity levels thanks to their sophisticated parts and steady cooling.

Important Things to Look for in Bangladesh Before Purchasing Water-Cooled Chillers

Knowing how a water-cooled chiller varies from air-cooled options in terms of capacity, upkeep, location needs, longevity, energy efficiency, and water consumption is crucial when making your decision. Here’s something to think about:

Capacity

Water-cooled chillers are perfect for high-capacity cooling in large facilities because their typical sizes range from 10 to 4,000 tonnes (35 to 14,000 kW).

Water-cooled systems offer more cooling capacity with fewer units than air-cooled chillers, making a more compact setup possible in demanding environments.

Maintenance Needs

Cooling towers are necessary for water-cooled chillers and present special maintenance requirements, including mechanical maintenance, condenser tube cleaning, and water treatment.

In order to ensure long-term efficiency and safety, water treatment programmes are especially necessary for open cooling towers to prevent the accumulation of bacteria and algae.

Adaptability to Location and Environment

Water-cooled chillers consistently work well in hot, humid climates, but they require a steady supply of water to run. Since air-cooled systems do not have to deal with freezing water in cooling towers, which may require additional equipment to prevent freeze damage in colder climates, they are easier to maintain in colder climates.

Energy Efficiency

Due to lower condenser temperatures, water-cooled chillers often consume less energy than air-cooled chillers. This efficiency is achieved because water-cooled systems depend on wet-bulb temperatures, which are usually lower than dry-bulb temperatures, requiring the compressor to do less work. The efficiency advantage is especially noticeable in climates with high humidity.

Longevity

Water-cooled chillers generally offer a longer lifespan, 20 to 30 years compared to the 15 to 20 years of air-cooled chillers. They are often installed indoors, operating at lower pressure, they experience less environmental stress, which can add to their durability.

Conserving and Using Water

Water-cooled chillers require a large and steady supply of water, which could raise operating costs in places where water is expensive or scarce. In contrast to water-saving air-cooled systems, which are favoured in areas with limited water supplies, they work best in places with reliable and reasonably priced water access.

Benefits and Drawbacks of Commercial and Industrial Water-Cooled Chillers

Large commercial and industrial facilities frequently choose chilled water systems because of their flexible capacity, centralized control, and energy-efficient cooling. These systems have many benefits, but they also have drawbacks, such as greater initial expenses and upkeep requirements.

To assist you in determining whether a chilled water system is the best option for your establishment, here are some of the main benefits and drawbacks.

Pros of Water-Cooled Chiller

Energy Efficient

Systems that use chilled water are very energy-efficient, especially when used on a large scale. Compared to smaller or decentralized systems, they effectively cool large areas while lowering overall energy costs.

Control and Management in One Place

These systems’ centralized control allows facility managers to monitor and modify cooling needs from one place. This efficient system guarantees constant cooling throughout the building and makes maintenance easier.

Flexibility of the System

Systems using chilled water can be adjusted or scaled to accommodate different cooling requirements. They are perfect for a variety of commercial settings because of their adaptable design, which enables customization based on the layout and cooling requirements of the building.

Longevity and Durability

Chilled water systems are long-lasting because they are constructed with sturdy parts like chillers, pumps, and premium piping. They are extremely durable when properly cared for, which lowers the need for frequent replacements and lowers long-term expenses.

Silent Operation

Chilled water systems, which are made to produce as little noise as possible, are appropriate for places like offices, hospitals, and schools where a calm environment is crucial. The occupants’ comfort in these environments is improved by this silent operation.

Optimal Use of Space

Chillers and cooling towers are examples of major outdoor components found in mechanical rooms or on rooftops in chilled water systems. This configuration frees up valuable indoor space for the building’s other uses.

Cons of Water-Cooled Chiller

Greater Initial Outlay

The cost of chillers, pipes, pumps, and specialised installation are among the high upfront expenses associated with installing a chilled water system. Some businesses may find these expenses prohibitive, so they should be budgeted for beforehand.

Complicated Installation Procedure

Chilled water system installation is a complicated process that calls for qualified experts. To increase system longevity and efficiency, component placement and design must be optimized.

Requirements for Regular Maintenance

For these systems to operate at peak efficiency and prevent problems like water leaks or decreased cooling effectiveness, regular maintenance is necessary. Water quality monitoring, component inspection, and quick leak repair are all part of maintenance.

Excessive Water Use

Significant water consumption by water-cooled systems could be problematic in places with scarce water supplies. To combat this, effective water management requires the implementation of water conservation measures and treatment procedures.

Danger of Leaks

With a vast system of pipes moving water, leaks are possible and, if not found quickly, could result in water damage and extra maintenance costs.

Considerable Room for Equipment

Chilled water systems require specific rooftop or outdoor spaces for chillers, cooling towers, and other equipment, even though they save space indoors. To guarantee optimum performance and accessibility, this arrangement should be taken into account during the design stage.

Conclusion

Take into account each system’s cooling requirements, energy efficiency, and long-term viability when choosing between water-cooled chillers and conventional air conditioning. For larger facilities, water-cooled chillers offer superior cooling capacity and energy savings, while air conditioning may be simpler and less expensive initially.

Water-cooled systems are perfect for high-performance settings because of their long lifespan and capacity to handle high cooling demands, despite the fact that they come with hefty upfront costs and maintenance requirements.

Which compressor is best for a water-cooled chiller?

One of four compressor types – reciprocating, scroll, screw, or centrifugal, is frequently used in chillers. It is frequently advised to use reciprocating compressors for peak cooling loads up to 80–100 tonnes. Using two or more chillers with reciprocating compressors can efficiently meet cooling demands for peak loads ranging from 100 to 200 tonnes.

Which type of chiller is the most efficient?

An integrated part load value (IPLV) of at least 5.2 and a minimum coefficient of performance (COP) of 4.2 are required for water-cooled chillers.

Air-cooled chillers, on the other hand, have an IPLV of 3.4 and a minimum COP of 2.5. In general, water-cooled chillers are quieter, smaller, last longer, and perform better than air-cooled chillers.

Which type of chiller is the most efficient?

Hospitals and other locations with high noise levels are the perfect place for water-cooled chillers. Water-cooled chillers use quietly circulating water to maintain cooling, which creates a quieter environment than air-cooled chillers, which rely on noisy fans.
