How Are Chilled Beams Installed?

Keeping your space cool and comfy can be tough, especially with the changing weather. Sometimes, old cooling systems just can’t keep up, making rooms too hot or cold and your energy bills high.

To install chilled beams, you first get ready by checking the space and picking the right tools. Then, you set up a strong frame on the ceiling, place the beams just right, connect them to the cooling system, and make sure everything works perfectly.

Each step, from preparation to finishing touches, is important to make sure your new cooling system works well and saves energy.

In this guide, we’ll explore what chilled beams are and walk you through their installation process, step by step. Let’s dive in and learn how chilled beams can make your space more comfortable and energy-efficient!

Getting Ready to Install Chilled Beams

Before diving into the actual installation of chilled beams, it’s important to get everything prepared. This stage is all about planning and making sure you have the right tools and equipment for the job.

Understanding Chilled Beams: First, understand what chilled beams are. They’re a type of cooling system used in buildings, where water flows through beams (usually mounted on the ceiling) to cool down a room. They work quietly and efficiently, making them popular in offices and other spaces.

Check the Space: Look at the area where you’ll install the beams. Is there enough room? You’ll need space above the ceiling to fit the beams and run pipes and electrical cables. Make sure there’s no obstruction like old wiring or plumbing that could get in the way.

Gather Your Tools and Materials: You’ll need various tools for the installation, like drills, screws, and measuring tape. Also, ensure you have all the parts of the chilled beam system, including the beams, brackets, pipes, and control units.

Plan the Layout: Decide where each beam will go. You want to place them evenly across the ceiling to cool the room effectively. Think about how the water pipes and electrical cables will reach each beam. Drawing a diagram can help visualize the setup.

Safety First: Safety is crucial. Make sure you have protective gear like gloves and safety glasses. Turn off any electrical circuits in the area where you’re working. Always follow safety guidelines to prevent accidents during the installation.

Getting ready is a big part of the installation process. It’s not just about having the right tools but also planning carefully and ensuring safety. Once everything is set, you can move on to installing the frame for the chilled beams.

Setting Up the Frame

The installation of the frame, or unistrut, is the foundational step in preparing for the chilled beam system. This structure must be securely attached to the building to support the weight of the chilled beams.

  • Unistrut Installation: Begin by installing the unistrut to the building’s structure. It’s essential to use the correct supports to ensure the unistrut can carry the load of the chilled beams. The unistrut should be positioned 14 inches above the finished ceiling level to align correctly with the installation plan.
  • Attaching Threaded Rod Studs: Once the unistrut is in place, attach 6-inch threaded rod studs to it using unistrut nuts. These rods should be spaced approximately 12 inches apart and will serve as the primary support points for the chilled beams.

Putting the Beams in Place

After the frame is set up, the next step is to install the chilled beams. Precision is key here to ensure the system operates efficiently and fits within the designated space.

  • Beam Placement: The chilled beam should be positioned 3 inches above the finished ceiling elevation. This height allows for the installation of the ceiling grid and other components. It’s crucial to locate the beam accurately, within plus or minus 2 inches of the specified technical zone location, to ensure it fits into the overall design and function of the space.
  • Securing the Beams: Fasten the chilled beams to the threaded rod studs protruding from the unistrut. This securement should be firm to prevent any movement or vibration that could affect the performance of the beams.
  • Flexible Hose Connections: Make the connections to the chilled beams using flexible hoses. These hoses allow for some movement and adjustment, which is essential for aligning the beams precisely within the space. If a hard connection is necessary, it should only be made after the beam is positioned correctly within the ceiling grid.

By following these steps, the chilled beams are securely installed and connected, ready for the next phases of the installation process.

Hooking Up and Checking the System

Once the chilled beams are in place, the next step is to connect them to the building’s mechanical systems and verify their operation.

  • Connecting to Cooling and Control Systems: Utilize the flexible hoses to connect each chilled beam to the building’s chilled water supply. This connection is crucial for the beams to function correctly and provide cooling. Ensure these connections are secure and leak-free to maintain system efficiency.
  • Electrical and Control Wiring: If the chilled beams have integrated controls or require electrical connections, complete these connections following the manufacturer’s guidelines. Proper wiring ensures that the beams operate correctly and can be controlled as needed.
  • System Testing: With all connections made, test the chilled beam system to ensure it operates correctly. This testing should include checking the water flow through the beams, ensuring there are no leaks, and verifying that the beams effectively cool the area. Adjustments might be necessary to achieve optimal performance.
  • Verification of Placement and Operation: Confirm that each chilled beam is correctly positioned within the technical zone and functions as intended. This ensures the system’s overall efficiency and effectiveness in cooling the designated space.

Completing the installation involves final checks, clean-up, and preparation for handover to the building’s operations team.

  • Final Inspections and Adjustments: Conduct a comprehensive inspection of the entire chilled beam system, checking for proper installation, secure fittings, and correct operation. Make any necessary adjustments to ensure the system is running efficiently.
  • Sealing and Insulation: Seal any gaps around the chilled beams and insulate the pipes as needed to optimize energy efficiency and prevent condensation.
  • Installing Ceiling Grid and Panels: If applicable, install the ceiling grid and panels around the chilled beams, ensuring they are accessible for maintenance and blend seamlessly with the aesthetic of the space.
  • Clean-up and Debris Removal: Clear the work area of all tools, materials, and debris. Leaving the site clean and safe is important for the final handover.
  • Documentation and Training: Provide detailed documentation of the installation process, including diagrams and operational manuals, to the building maintenance team. Offer training if necessary to ensure they understand how to operate and maintain the chilled beam system.
  • System Monitoring and Follow-up: Arrange for ongoing monitoring of the chilled beam system to ensure it continues to operate efficiently. Plan for follow-up visits to address any issues and perform routine maintenance.

After installation, it’s essential to also consider the importance of troubleshooting chilled beam issues and exploring retrofitting options for chilled beams. By methodically completing these steps, the chilled beam installation is finalized, ensuring a well-functioning, efficient cooling system that meets the building’s requirements.
