1. Lesser Cost

The energy efficiency of a chilled water system is higher than that of smaller, separate systems. They’re ideal for huge commercial buildings that need a lot of air conditioning. While chillers are more expensive upfront, they allow you to have a more efficient system and save money on energy use. As a result, they provide for a high return on investment in a short period of time.

2. Practicality

Chilled water systems may cool an entire building or a group of buildings. As a result, they are a more feasible choice for centralising air conditioning equipment. You won’t have to install as many distinct pieces of equipment in various locations. Because of this, it’s also a wonderful technique to make access to the units for maintenance easier.

3. Better Indoor Air Quality

Indoor spaces are interconnected when a building utilises just air ducts. Air pollution and bad odours can readily spread to other sections of the building with this setup. A chilled water system, on the other hand, allows for the employment of a separate air handling system for each location, effectively separating air contaminants and smells. Areas with independent duct systems are not affected if one region has an issue with air quality.

4. Flexibility

There are several configurations for chilled water systems. They may be installed both indoors and outdoors, and different compressors and refrigerants can be used depending on the cooling capacity and efficiency required. In a nutshell, chillers are extremely adaptable. They may provide a wide range of choices and attachments, allowing the chiller unit to be properly tailored to the demands of a given application. They can also be used in conjunction with a wide range of terminal units, including fan coils, floor cooling/heating, AHUs, ice bank systems and other chiller cascade systems.

5. Safety

Toxicity, flammability, asphyxiation and physical dangers are all risks associated with having a refrigerant pumped throughout your structure. A chilled water system eliminates these risks, making it the safest alternative. Water is chemically stable, noncorrosive, nontoxic, has a higher thermal conductivity and is relatively cheap. When compared to other fluids such as sodium chloride brines, propylene glycols, ethylene, methanol, or glycerin, it is a healthier and more ecologically friendly option.

Conclusion

Overhead expenses, performance and safety are all major concerns for every business enterprise that must be managed properly. Regardless of the circumstances or considerations to consider, a reliable air conditioning system is essential for productivity and safety. A chilled water unit can aid in this situation. These benefits, however, do not negate the benefits of alternative HVAC options. They all have their place, depending on the demands of the facility owner and the requirements of a given project.

An industrial water chiller is essential for any facility using large machinery that generates significant heat. These chillers help maintain a low temperature within your facility and cool down internal machine equipment. By understanding how these chillers work, you can make informed decisions about your cooling needs. Let's dive into the details of industrial water chillers.

What is a Chiller?

Chillers are widely used in both commercial and industrial settings. Essentially, a chiller is a refrigeration system designed to cool liquids or mechanical equipment. The primary function of a chiller is to remove unwanted heat while maintaining stable temperature, pressure, and current in the machinery or production process. This is done by circulating a heat-absorbing process through the refrigeration cycle within the chiller.

Industrial chillers are used to control the cooling—either directly or indirectly—of products, mechanisms, and machinery in various industries. Despite the different types of industrial chillers, they all use air or water as a cooling method during the refrigeration cycle.  

For instance, an air-cooled chiller cools the system with fans, while a water-cooled chiller uses circulated water from a cooling tower. These systems can cool water to below ambient temperature or even below freezing. Water chiller capacities are typically measured in cooling tons, KCAL/hr, or BTU/hr. For instance, Creworks' 6-ton water chiller can achieve cooling capacities of up to 61,200 BTUs per hour.

Why Do You Need a Chiller System?

Industrial operations generate heat through friction and high-powered equipment like furnaces or engines, or through temperature-sensitive materials such as plastics. To prolong the lifespan of heavy-duty equipment and speed up production via shorter cycle times, chiller units are installed to circulate cooled liquid through the equipment.

Selecting the right chiller for your application can help you save costs, reduce downtime, and increase production capacity and operational efficiency. The two main types of industrial chillers used today are air-cooled and water-cooled chillers, which we will discuss further.

Types of Industrial Chillers: Air-Cooled vs. Water-Cooled

There are two types of condensers used in chillers: water-cooled and air-cooled. In a refrigerant cycle, the hot refrigerant gas from the compressor needs to be cooled in the condenser. It then enters the expansion valve into the evaporator to generate chilled water and achieve the desired cooling cycle.

Air-Cooled Chillers

Air-cooled chillers have condensers that use ambient air to cool the hot refrigerant gas. These chillers are usually installed in areas with good airflow, as they rely on fans instead of cooling towers to dissipate heat. An air-cooled chiller absorbs heat from processed water and transfers this heat into the air.

Water-Cooled Chillers

Water-cooled chillers have condensers that use water from a cooling tower to cool the refrigerant gas. Once the refrigerant is cooled and released via an expansion valve, it cools the circulating water in the chiller to reach the target temperature. The processed water acts as a medium for heat transfer.

Air or Water Chillers: Which One Suits Your Needs?

Both air-cooled and water-cooled chillers are designed to facilitate the discharge of heat from the production process. They produce the same cooling capacity under the same compressor power. Therefore, your decision should be based on your working environment and the purpose of use.

How Do Industrial Water Chillers Work?

Nearly every industrial process generates heat. If this unwanted heat accumulates, it can reduce the productivity of your machinery and factory. Excessive heat could even lead to shutdowns or early equipment failure. Incorporating a cooling process into your industrial system design can help avoid these issues.

Components of a Chiller

The essential components of a chiller include a compressor, condenser, expansion valve, and evaporator. These components work together to circulate a refrigerant that removes heat from a process, operation, or space.

Compressor

The compressor is the major component of a refrigeration unit. It circulates the refrigerant (freon gas) and converts it from low-pressure to high-pressure before it travels to the condenser to discharge its heat.

Condenser

The condenser cools the gas by transferring heat from the refrigerant to the outdoor cooling medium (air or water). It also condenses the refrigerant, converting it from a gas to a liquid.

Expansion Valve

The liquid refrigerant passes through the expansion valve before entering the evaporator for heat exchange. The expansion valve lowers the high pressure and temperature of the refrigerant liquid, converting it into a low-pressure, low-temperature wet vapor, which is then sent to the evaporator.

Evaporator

The evaporator is where the actual heat exchange happens. The processed water from the expansion valve enters the evaporator to start the cooling process.

Which Industries Need a Water Chiller?

Water chillers are used in various industries, including:

• Plastic manufacturing and processing
• Metal forming
• Food and beverage processing
• Machinery
• Chemical and pharmaceutical
• Medical (MRI, CT scanner, x-ray, linear accelerator, laboratory)
• Shoe industry
• Laser cutting
• Transportation manufacturing

Things to Consider Before Selecting a Water Chiller System

Using a water chiller in a factory has numerous benefits. However, these benefits can only be realized if you have the right chiller installed. Consider the following questions before purchasing a water chiller system:

• What's the heat load of your intended application?
• What coolant type, target temperature, and flow rate does the chiller system provide?
• In what environment will the water chiller be installed, and what are the site conditions?
• Does this water chiller model meet or exceed the required capacity? (check the chiller performance curves)
