District Cooling and the Effects of Low Delta T

    Posted on Mon,Mar 05, 2018 @ 09:36 AM

    new-chiller-1.jpgDistrict cooling is the centralized production and distribution of cooling energy. Chilled water is delivered from a centralized energy plant through an underground pipeline to commercial, industrial, and residential buildings to air-condition using chilled water.  Excess heat is extracted from the building by the air conditioning systems’ heat exchangers. The water is then returned to the central energy plant.

    District cooling plants operate to meet the cooling energy demand of their customers, which could be dozens of buildings in a college campus or municipality. District cooling systems offer lower up-front construction costs and eliminate the need for chiller plant maintenance at the building level.

    Customers of a district cooling plant pay for the volume of chilled water delivered to their building and may pay other charges as well.  A peak demand charge may be assessed and penalties for returning water below the design or contracted temperature due to poor heat exchange. Our industry has proven that lower return water temperatures and low delta T decrease the efficiency of the entire chilled water system.  This condition is known as “Low Delta T Syndrome.”  Low Delta T syndrome is the result of the inefficient use of chilled water at the point of consumption.  Belimo is sponsoring a webinar with High Performance Building on District Cooling and the effects of low Delta T.  This webinar will provide a review of district chilled water system design and how low Delta T impacts both the chillers and the buildings the chillers are serving. We will also cover low Delta T and how it impacts pumping, causes of low Delta T, attempts to correct low Delta T and the relationship between low Delta T and chiller capacity. In conclusion, we will review a study of a building where “Low Delta T Syndrome” was corrected at the point of water to air heat transfer.

    Webinar Objectives:

    • Identifying the importance of system design and pumping arrangements
    • Understanding the relationship between GPM and Delta T
    • How to calculate Btu and Tons
    • The types of district cooling building connections
    • Why maintaining Delta T is important in a district cooling system

    Super Capacitor for Critical Applications

    Posted on Tue,Oct 03, 2017 @ 10:53 AM
    SuperCap-Applications-Belimo.jpg

    Super capacitors (SuperCaps) are electrochemical condensers that are faster in response and more reliable than conventional rechargeable batteries. This modern energy storage technology is advancing energy efficiency and the functionality of complex safety solutions around the globe. Belimo has intensively tested and improved the SuperCap technology to equip damper and valve actuators with an innovative electronic fail-safe control function. Testing was under harsh conditions temperatures of 122°F to -22°F [50°C to -30°C] and long-term charging and discharging. Testing focused on the reliability of the electronic fail-safe function with continuous loads. To combine SuperCap technology with fail-safe control actuators, Belimo needed to develop and patented a SuperCap energy management algorithm included in the actuator microprocessor controller. The algorithm safely charges and discharges the SuperCap energy to deliver and ensure reliable long service life.

    This technology is applied wherever safety and energy efficiency are required. SuperCaps absorb energy very quickly and discharge as required. It offers a longer service life and greater cycle-resistant than rechargeable batteries. These properties are desirable for high-tech applications such as defibrillators, aviation emergency exits, automotive air bags, wind turbines, and smart grids.

    SuperCap technology offers HVAC system protection with increased efficiency and speed. During an electrical power supply interruption, dampers and valves automatically returned to their fail-safe position with an electronic fail-safe control function. Water coils are protected from freezing, steam heat exchangers are closed for safety, and fume hood exhaust systems are opened to ensure ventilation. Belimo electronic fail-safe actuators with SuperCap technology offer speed, efficiency, reliability, and versatility.

    Correcting Low ∆T in Buildings with District Cooling

    Posted on Tue,Aug 15, 2017 @ 03:39 PM

    Chilled water provided from a utility plant is commonly in a building’s HVAC system in lieu of installing chillers. Lower return water temperatures or low ∆T decreases the efficiency of the entire chilled water system. This condition is known as “Low ∆T Syndrome”. Low ΔT syndrome is the result of the inefficient use of chilled water at the point of consumption. Join our webinar on Wednesday, August 23, 2017 at 1:00PM - 2:00PM EDT. 

    Delta_T_Webinar_600x260_3-1.jpg
    This presentation will provide a review of district chilled water system design and how low ∆T impacts both the chillers and the buildings the chillers are serving. Finally, we will review a study of a building where “Low ∆T Syndrome” was corrected at the point of water to air heat transfer.

    Helping Mushrooms Grow More Efficiently

    Posted on Tue,Jun 27, 2017 @ 09:00 AM

    In the production plant of Kuhn Champignons AG, seven to eight tons of mushrooms produced daily. To accelerate the growth, an artificial "autumn climate" is created. Under the ideal temperature and humidity, the mushrooms grow, ripen and become ready for harvest within three weeks.

    But after 30 years, the existing plant and hydraulics were obsolete and no longer met the current standards of sustainable production. The entire plant needed updating.

    After 30 years, the existing plant and hydraulics were obsolete and no longer met the current standards of sustainable production. The entire plant needed updating. Energy saving was the main objective for the new production plant. Additional requirements were constant temperature and humidity in the production for the optimal growth of mushrooms and the ability to switch to variable amounts of water to be able to react according to the season and demand. Reliable and innovative products that contribute to energy saving.

    The advanced butterfly valve assembly fulfills the task of dissipating the heat within the plant, which means the warm water will be pumped into the ground water for cooling again. This is a daily occurrence. The butterfly valve assembly was easy to install because of its lower height and reduced weight.  The advantage of the hand crank if the need arises to switch the system to manual operation. The biggest benefit is 80% energy savings.  The advanced butterfly also guaranteed reliable operation through intelligent self-adjusting valve design Near Field Communication(NFC) along with BACnet communication provide superior application data access for easy troubleshooting, commissioning, and programming.

    The innovative advanced butterfly valve was installed in the new plant of Kuhn Champignon AG in March 2016 and has been running flawlessly. The advanced butterfly valve is the most intelligent, energy efficient, and reliable high flow solution in the HVAC market. With a focus on ease of installation, application flexibility, and longevity, this series set new performance standards.
