Why Chillers are Vital for Hydrogen Infrastructure

The Importance of Industrial Chillers in Hydrogen Station Systems

As the world shifts towards cleaner energy sources, hydrogen fuel is becoming an increasingly popular alternative to traditional fossil fuels. Hydrogen fuel cell vehicles are already on the roads, and the infrastructure to support them is rapidly expanding. One key component of this infrastructure is the hydrogen refueling station, which uses industrial chillers to cool and compress hydrogen gas for storage and dispensing.

What is an Industrial Chiller?

An industrial chiller is a piece of equipment that uses refrigeration technology to cool water or other fluids to a desired temperature. This chilled fluid can then be used to cool other equipment or processes. Industrial chillers come in a variety of sizes and configurations, depending on the specific application.

How Does an Industrial Chiller Work in a Hydrogen Station System?

In a hydrogen station system, an industrial chiller is used to cool and compress hydrogen gas. When hydrogen is produced, it is typically at a high temperature and pressure. To store and dispense the hydrogen safely, it must be cooled and compressed to a lower temperature and higher pressure.

The process begins with the hydrogen gas being fed into the chiller. Inside the chiller, the gas is cooled by a heat exchanger that uses chilled water or another cooling fluid. As the gas is cooled, it condenses into a liquid, which is then compressed by a pump to increase its pressure.

The compressed liquid hydrogen is then stored in high-pressure tanks until it is needed for refueling. When a vehicle pulls up to the refueling station, the liquid hydrogen is dispensed into the vehicle’s fuel tank, where it evaporates back into a gas and is used to power the vehicle’s fuel cell.

Hydrogen station chiller system

Why are Industrial Chillers Important in Hydrogen Station Systems?

Industrial chillers are a critical component of hydrogen station systems for several reasons. First, they are necessary to cool and compress the hydrogen gas for storage and dispensing. Without industrial chillers, it would be impossible to safely store and distribute hydrogen fuel.

Second, industrial chillers help to improve the efficiency of the hydrogen production process. By cooling the hydrogen gas before it is compressed, less energy is required to compress it to the desired pressure. This means that more of the energy from the original source (such as solar or wind power) can be used to produce hydrogen, rather than being lost as waste heat.

Finally, industrial chillers help to ensure the safety of hydrogen refueling stations. Hydrogen gas is highly flammable, and storing it at high pressures can be dangerous if not done correctly. By cooling and compressing the gas in a controlled manner, industrial chillers help to minimize the risk of accidents and ensure that refueling stations are safe for both customers and employees.

Types of Industrial Chillers Used in Hydrogen Station Systems

There are several types of industrial chillers that can be used in hydrogen station systems, depending on the specific requirements of the application. The most common types include:

Air-Cooled Chillers

100 ton air cooled chiller kaydeli

Water-Cooled Chillers

100 ton water cooled chiller

Water-cooled chillers use water to dissipate heat from the cooling fluid. They are generally more efficient than air-cooled chillers and can provide more precise temperature control, but they require a constant supply of water and may be more expensive to install and maintain.

Conclusion

Industrial chillers are a critical component of hydrogen station systems, enabling safe and efficient storage and dispensing of hydrogen fuel. By cooling and compressing the hydrogen gas, industrial chillers help to improve the efficiency of the production process while ensuring that refueling stations are safe for both customers and employees. With continued investment in clean energy infrastructure, industrial chillers will play an increasingly important role in supporting the transition to a more sustainable future.

To overcome this obstacle, an 80-ton water-cooled chiller from KAYDELI was employed to maintain a constant temperature of -8℃. This article explores the critical role of the chiller, the use of a glycol mixture as a coolant, and the essential components required to create a typical ice rink.

Ice rink chiller diagram

  1. The Chiller: A Key Player in Ice Rink Construction

The 80-ton water-cooled chiller emerged as the hero of the ice rink construction project. With its impressive cooling capacity (183.1kW at -10℃), it ensured that the required temperature of -8℃ was consistently maintained. As per our client’s requirement, we chose the water-cooled type which is more efficient in terms of cooling and low maintenance. By utilizing advanced cooling technology, the chiller effectively counteracted the warm climate of Guangdong province, creating an ideal environment for ice skating enthusiasts.

  1. The Glycol Mixture: A Reliable Coolant

To achieve the desired temperature, a glycol mixture was selected as the coolant for the ice rink. Glycol, a type of antifreeze, possesses excellent thermal properties and prevents freezing at subzero temperatures. By circulating the glycol mixture through the piping system, the chiller efficiently transferred heat away from the ice surface, keeping it frozen and safe for skating.

  1. Piping System: Supplying Coolant for Optimal Cooling

A well-designed piping system played a crucial role in supplying the glycol mixture throughout the ice rink.

Heat pump system for green house

Heat pumps working principle in the greenhouse

A greenhouse is a valuable tool for any farmer or gardener looking to extend their growing season and protect their plants from harsh weather conditions. However, maintaining a consistent temperature inside a greenhouse can be a challenge, especially during extreme weather conditions. This is where a heat pump comes in handy.

A heat pump is an energy-efficient heating and cooling system that can be used to regulate the temperature inside a greenhouse. It works by extracting heat from the air or ground outside the greenhouse and transferring it inside to warm the space during the winter. During the summer, the heat pump can reverse the process and extract heat from inside the greenhouse and release it outside to cool the space.

One of the main benefits of using a heat pump in a greenhouse is that it can provide consistent temperature control throughout the year. This is important because plants require a specific temperature range to grow and thrive. If the temperature inside a greenhouse fluctuates too much, it can cause stress to the plants and even damage them. By using a heat pump, farmers and gardeners can ensure that their plants are kept at a consistent temperature, regardless of the weather conditions outside.

Another benefit of using a heat pump in a greenhouse is that it is an energy-efficient solution for heating and cooling. Heat pumps use electricity to transfer heat, rather than generating heat through combustion like traditional heating systems. This means that they can provide the same amount of heating or cooling with less energy, resulting in lower energy bills and reduced carbon emissions.

Heat pump with water tank

So how do heat pumps work for cooling and heating? There are two main types of heat pumps: air-source and ground-source. Air-source heat pumps work by extracting heat from the air outside the greenhouse and transferring it inside. They do this by using a refrigerant that absorbs heat from the air and then compresses it to increase its temperature. The heated refrigerant is then circulated through a coil inside the greenhouse, where it releases its heat to warm the space.

Ground-source heat pumps work in a similar way, but they extract heat from the ground instead of the air. They do this by using a loop of pipes buried underground that are filled with a water and antifreeze solution. The solution absorbs heat from the ground and is then pumped through a heat exchanger inside the greenhouse to warm the space.

Both types of heat pumps can also be used for cooling by reversing the process. Instead of extracting heat from outside or underground, they extract heat from inside the greenhouse and release it outside. This cools the space down to the desired temperature.

In summary, a greenhouse needs a heat pump to keep it warm during the winter and cool during the summer because it provides consistent temperature control and is an energy-efficient solution for heating and cooling. Heat pumps work by extracting heat from outside or underground and transferring it inside to warm the space, or extracting heat from inside and releasing it outside to cool the space. By using a heat pump, farmers and gardeners can ensure that their plants are kept at a consistent temperature throughout the year, resulting in healthier plants and higher yields.

Glycol chillers for brewing industry

How Glycol Chillers Works In The Brewing Industry

A glycol chiller is an essential component in the brewing industry as it helps maintain the ideal temperature for the brewing process. The brewing process involves a complex series of chemical reactions that are temperature-dependent. As such, it is crucial to keep the temperature within a specific range to ensure that the beer quality is consistent and of high quality.

Glycol chillers are used to regulate the temperature of the glycol solution, which is then circulated through the cooling jackets of the fermenters and bright tanks. The glycol solution absorbs the heat generated during fermentation and transfers it to the chiller, where it is expelled into the atmosphere. This process prevents the beer from overheating, which can lead to undesirable flavors and aromas.

Here is how it works:

Glycol chillers for brewing industry

Glycol chillers work by circulating a glycol solution through a closed-loop system that includes fermentation tanks, conditioning tanks, and heat exchangers. The glycol solution absorbs the heat generated during the fermentation process and transfers it to the chiller, where it is expelled into the atmosphere.

The glycol solution is pumped through cooling jackets that surround the fermentation and conditioning tanks. As the glycol solution circulates through the jackets, it absorbs the heat generated by the yeast during fermentation. The heated glycol solution is then pumped back to the chiller, where it is cooled down before being recirculated through the cooling jackets.

Glycol chillers can also provide cooling for the storage room by circulating cool glycol solution through air handling units. This process helps maintain a consistent temperature in the storage room, preventing spoilage of the beer.

In addition to cooling the fermentation and conditioning tanks, glycol chillers can also be used in heat exchangers to chill the beer. The beer is passed through a heat exchanger that is cooled by the glycol solution. As the beer passes through the heat exchanger, it is rapidly cooled down to the desired temperature before being transferred to the conditioning tanks.

Glycol chillers are also used in other industries such as food processing, pharmaceuticals, and HVAC systems. In the food processing industry, glycol chillers are used to maintain the temperature of food products during production. For example, they are used to cool chocolate during the tempering process or to keep ice cream mixtures at a specific temperature during production.

In the pharmaceutical industry, glycol chillers are used to maintain the temperature of vaccines and other medications. Vaccines require strict temperature control during storage and transportation to ensure their efficacy. Glycol chillers are used to keep the vaccines at a specific temperature range to prevent degradation and ensure their effectiveness.

In HVAC systems, glycol chillers are used to cool water that is circulated through air handling units to regulate the temperature of a building. This process helps maintain a comfortable indoor environment for occupants.

In conclusion, glycol chillers are essential components in various industries, including the brewing industry. They help maintain the ideal temperature for different processes, ensuring consistent quality and preventing spoilage. Other industries such as food processing, pharmaceuticals, and HVAC systems also rely on glycol chillers for temperature regulation.

Advanced Cooling with Heat Pump Chiller

An air-cooled heat pump chiller is a type of HVAC system that uses outdoor air as the source for both heating and cooling. It works by absorbing heat from the outdoor air and transferring it indoors to provide warmth during colder weather, and by removing heat from indoors and transferring it outside to provide cool air during hotter weather. The system uses a refrigerant to facilitate the heat transfer process and can be an efficient and cost-effective way to regulate indoor temperature.

In a commercial building, an air-cooled heat pump chiller works by following these basic steps:

  1. The outdoor unit of the chiller absorbs heat from the surrounding air using a refrigerant. This heat energy is then transferred to the indoor unit through the refrigerant lines.
  2. The indoor unit of the chiller uses heat energy to warm up the air in the building through a process called heat exchange. This warmed air is then circulated through the building’s ductwork to provide heating.
  3. During the summer months, the process is reversed to provide cooling. The indoor unit absorbs heat from the indoor air and transfers it to the outdoor unit, which then releases it into the surrounding air.
  4. The chilled air is then circulated through the building’s ductwork to provide cooling.

Overall, an air-cooled heat pump chiller provides both heating and cooling by transferring heat energy between the indoor and outdoor units using a refrigerant. This allows for efficient temperature control in commercial buildings.

There are several advantages to using air-cooled heat pumps, including:

  • Energy efficiency: Air-cooled heat pumps are highly energy efficient, as they use the surrounding air to provide heating and cooling. This can result in lower energy bills and reduced carbon emissions.
  • Easy installation: Air-cooled heat pumps are easy to install and require less space than other HVAC systems, as they do not require a separate cooling tower or water source.
  • Low maintenance: Air-cooled heat pumps require less maintenance than other HVAC systems, as they have fewer moving parts and do not require regular water treatment.
  • Flexibility: Air-cooled heat pumps can be used in a variety of settings, including commercial buildings, residential homes, and industrial facilities.
  • Cost-effective: Air-cooled heat pumps can be a cost-effective option for heating and cooling, as they can provide both functions with a single system.

Overall, air-cooled heat pumps offer several advantages over other HVAC systems, including energy efficiency, easy installation, low maintenance, flexibility, and cost-effectiveness.

Temperature Control System for Crystal Growth Furnace

What is a crystal growth furnace system?

A crystal growth furnace system is a machine used to grow crystals in a controlled environment. It typically consists of a furnace, which heats the material to the desired temperature, and a chamber where the crystal growth occurs. The system is designed to maintain specific temperature, pressure, and atmospheric conditions to ensure optimal crystal growth. These systems are widely used in the semiconductor, electronics, and materials science industries.

How does it work?

The working principle of a crystal growth furnace system is based on the controlled heating and cooling of a material to promote crystal growth. As mentioned earlier the system typically consists of a furnace, which heats the material to a high temperature, and a chamber where the crystal growth occurs. The material is melted and then slowly cooled under controlled conditions to promote the formation of a crystal lattice structure. The rate of cooling and other environmental factors such as pressure and gas composition can be adjusted to optimize the crystal growth process. Once the crystal has formed, it can be harvested and used for various applications.

Why a chiller is required for the process?

A chiller is required in a crystal growth furnace system to maintain a stable temperature within the system. The furnace heats the material to a high temperature, but it is important to cool the surrounding environment to prevent unwanted reactions and maintain a stable temperature for crystal growth. A chiller circulates a coolant, typically water, through the system to remove excess heat and maintain a stable temperature. The temperature of the coolant can be adjusted to control the temperature of the system, allowing for precise control of the crystal growth process. Without a chiller, it would be difficult to maintain a stable temperature and optimize crystal growth.

Here is one of our recent projects for an African crystal growth company.

KY Crystal growth furnace

In this project, Kaydeli used two of their air-cooled chillers KC-040TB and KC-050 TB to accomplish the project.

A total of five crystal growth furnaces are installed in this process, three KY crystal growth furnaces, and two GT crystal growth furnaces. The maximum production load operation does not exceed three crystal growth furnaces, and each cycle corresponds to the maintenance of different crystal growth furnaces.

The cooling water demand for a single unit of KY crystal growth furnace equipment is: 6m³/h, the constant temperature of the cooling water supply is 28°C±1°C, and the water inlet pressure of the crystal growth furnace is 0.2MPa-0.22MPa. The gravity flow returns to water, and the water inlet pressure of the power cabinet 0.2MPa-0.3MPa. The outlet water temperature rises by 5~7°C.

Here is the design of a set of cooling circulating water systems, using two air-cooled industrial chillers to cool down the normal temperature water in the 12 cubic reservoirs to the set temperature, and then the cold water in the reservoir is delivered to the crystal growth furnace equipment by the process water pump.

Two air-cooled industrial chillers are selected, one with a cooling capacity of 113.1KW (the other one has a cooling capacity of 141.4KW), an overall unit composed of four compressors, four independently operating refrigeration systems, process water pumps, air conditioning circulation pumps, and, centrifugal pumps. The material of the water supply and return pipes is 304 stainless steel(SS), and each device is equipped with 304 stainless steel (SS) valves. The air-cooled industrial chiller integrates the refrigeration system, water tank, and water pump for easy use and operation. The unit is compact and occupies a small area. It can be used when it is connected to water and electricity.

Intelligent control, using a high-precision LCD digital controller, can intuitively and accurately measure the outlet water temperature, the operation panel can intuitively display the operation and fault status of the compressor, water pump, and refrigeration system at a glance. Only pressing the start and stop buttons can run the equipment automatically. Simple operation and convenience.
