Belimo Energy Valve™:  Making Systems Energy Efficient, Easier to Control and More Transparent

Posted on Tue,Feb 21, 2017 @ 11:15 AM

The Belimo Energy Valve is an advanced pressure independent control valve that can drastically reduce the amount of water used to cool or heat a space.  By increasing the overall efficiency of the heat transfer, energy savings can be achieved.  In addition, the Belimo Energy Valve provides unparalleled transparency to the system and can drastically improve the controllability of complex hydronic systems.

Join us for this webinar to understand the practical science behind the improved performance and the potential gains that can be realized in your buildings. The webinar will cover:

Why Hydronic Design Models Don’t Match Building Performance

Modelling softwares make a few faulty assumptions about basic hydronic behavior which can lead to disappointing building performance.  By selecting and installing proper equipment, engineers and contractors can be successful in achieving the modelled results.

Understanding and Improving Heat Transfer at the Coil

By understanding the thermodynamics behind the heat transfer at coils and heat-exchangers, we can devise better control strategies to better match the water flows to the specific loads in the space.  When done properly, most buildings can use far less water to heat and cool, and thus save large amounts pumping and plant energy.

Static vs. Dynamic Balancing

Until examined closely, the true benefits of advanced control valve technology, may be overlooked from a control and comfort standpoint.  By exploring dynamically balanced systems, we can see how we can hope to have more stable loops and more comfortable spaces.

Belimo Energy Valve

The Belimo Energy Valve is an electronically pressure independent valve with a fully integrated BTU meter.  It has the ability to control flow, manage Delta T, monitor system glycol percentage and fully expose the performance of the equipment.  With advanced communication platforms, which include BACnet, MODbus, IP and cloud based optimization, the Belimo Energy Valve provides unparalleled access to all of the data.

Pressure Independent Valves offer system stability, improved efficiency and overall versatility that can only be achieved in a dynamically balanced hydronic system. During this webinar you will learn how partial loads can wreak havoc on statically balanced systems and how static balancing devices under perform the majority of the time. See how pressure independent valves can keep your system balanced at all loads and flow, eliminate overflows, and achieve perfect valve authority.

Join us on Thursday, September 15th at 11:00AM PDT / 2:00PM EDT as Dick Hubbell, Regional Application Consultant for Belimo America discusses why design and modeling data doesn't always match a building’s actual performance.

Energy and performance models make a few faulty assumptions about hydronic performance. By understanding these assumptions, we can have a better view of actual performance. This presentation will examine the performance impact of improper valve sizing, unstable system pressures and balancing device selection. We will also examine the physical effects of valve authority and coil degradation in hydronic systems.
In this session we will discuss:

  • Design and Modeling Assumptions

  • Hydronic Heat Transfer at the Coil

  • Hydronic Performance Problems

  • Valve Sizing

  • Static vs. Dynamic Balancing

  • Coil Performance

  • Optimize Potential Performance Solutions

Predicting tomorrow's complex technical issues and solutions is a challenge. Stay current withNEBB NEBB's webinar series - NEBBinar - live webcasts that will provide insights on key changes affecting your business.

On November 13th at 4:00 pm (EST) NEBB along with Belimo Americas will be hosting a webinar on: New Technology to Improve Low Delta-T Syndrome Large Facilities. Low Delta-T Syndrome is a common (and costly) problem in many large facilities, especially on sprawling campuses with central chilled water plants. Learn how the new Energy Valve helps detect and address all of the following scenarios that commonly impact coil performance and thus system efficiency:Delta T

  • Coil degradation due to fouling and scale
  • Improperly sized coils
  • Poor valve authority results in under or overflow of the coil
  • Changes made elsewhere in the system that frequently impact other circuits which are inherently interactive

Once these problems are eliminated, the opportunities for system wide optimization open up.  At that point, owners, engineers, and contractors realize a host of benefits enabled through the Belimo Energy Valve:

    • Combat Low Delta T. The risk of Low Delta T (the most common culprit of major system inefficiencies) is dramatically reduced or eliminated.
    • Enhanced Energy Optimization.  Owners capitalize on optimization strategies such as variable flow pumping without risking occupant comfort.
    • Improved Commissioning. Start-up commissioning as well as retro-commissioning is greatly simplified.
    • Better System Maintenance. Operators are much more informed about coil performance and thus better able to schedule preventive maintenance measures.
    • Green Certifications. The Belimo Energy Valve’s ability to analyze, document and optimize performance data to the BAS contributes toward satisfying credit EAc5: Measurement and Verification under LEED.
    • More Effective Control. Engineers are able to implement more advanced control strategies by taking advantage of the data logging provided at individual coils.
    • Smaller Equipment. Buildings are able to meet comfort demand with smaller, less expensive piping and equipment.

Pressure Independent Control Valve Technology: What’s in it for YOU?

Posted on Mon,Oct 08, 2012 @ 10:00 AM

Building owners don’t care about what Pressure Independent (PI) Control Valve technology does. They only care about what it saves. With the new Belimo PIV Energy Modeling Plug-in, mechanical designers can accurately determine the energy savings associated with PI control valves. And they can share this valuable information with building owners in a way that is valuable and real to them!
The PIV Plug-in was developed for use with two of the most popular building energy simulationTrane Trace™ 700 tools on the market, Trane Trace™ 700 and DOE eQuest to answer these important questions:
•    What’s the payback for using PI control valves in a given building?
•    How do I quantify the benefits of PI technology so I can justify the cost to an owner?
•    How many LEED points can I get for using PI control valves?

“Best Case” Versus “Base Case”
How much energy does a poorly controlled hydronic system waste? Until now, we never really knew. That’s because most modeling tools assumed the impossible – that all pressure dependent control systems controlled flow perfectly!

We know that’s not the case. The fact is, without pressure independent technology, hydronic systems suffer from inaccurate control all the time. Chronic over-flow through coils, poor waterside ∆T, and inefficient operation problems are the rule, not the exception. This is evidenced in the epidemic numbers of “Low Delta T Syndrome” in HVAC systems.

Engineers could never really accurately model energy efficiency with these “best case” assumptions. Nor could they demonstrate the benefits of pressure independent control without a “base case” comparison. Not until now.

Modeling that Reflects Real World Scenarios
With the help of Belimo’s PIV Energy Modeling Plug-in, engineers can finally model a building with and without pressure independent control valves!
This executable file installs new pump performance curves that allows owners to compare a system design with and without pressure independent control valves.
With this new modeling capability, engineers can:
•    Compare the annual energy consumption of two models to estimate the savings achieved through pressure independent control valves.
•    Calculate a reliable ROI for Pressure Independent Control Valves.
•    Generate necessary documentation for LEED points achieved under Energy and Atmosphere Credit 1: Optimize Energy Performance.

Credible Curves – the Key to a “Base Case” Comparison
Belimo pressure dependent pump performance curves are installed in the standard Trane Trace™ 700 and eQuest performance curve libraries, so their operation is fully transparent and compatible with existing models.

Belimo developed these curves through intense study and collaboration with leading experts in energy modeling and software engineering. They are based on actual, newly installed hydronic systems with conventional pressure dependent control valves. They are the key to the base comparison that engineers need to quantify and demonstrate the savings of pressure independent control valves.

Full documentation of the development of the Belimo pressure dependent pump performance curves is included along with the plug-in to make your models easily defensible to the most demanding audience.

Software is Free and Installs in Seconds!Belimo PIV Energy Modeling Plug-in
The Belimo PIV Energy Modeling Plug-in for Trane Trace™ 700 and eQuest installs on your computer in seconds. Software management utilities are included to allow you to remove the software should you ever desire to.
Computer Requirements:
•    Microsoft Windows XP, Windows XP Professional, or Windows 7
•    Trane Trace 700, Version 6.2.X and/or eQuest, Version 3.6X
