Ice Storage: Design and Application - Trane

1 Engineers newsletter live Course Outline Ice Storage: Design and Application The grid of the future will incorporate a higher percentage of renewable energy (like wind and PV solar). Unfortunately these energies have no natural storage mechanism. Thermal storage is the easiest way to restore this critical component of fossil fuel-based energy. We ll cover a bit of theory and Application , then Design a small ice storage system from layout to operation and control. We ll discuss how to make it affordable on small chilled-water systems, expose hidden costs in energy tariffs, and identify and address the most common stumbling blocks. By attending this event you will learn: 1. A clear understanding of ice storage 2. An economic rationale for ice storage 3.

2 How to dispel common myths about ice storage 4. How to avoid the most common stumbling blocks Program Outline: 1) Overview Why ice now? 2) Typical applications a) Ice storage overview b) Design overview 3) Qualifying a job a) Ice storage Design process b) Qualifying preliminary analysis c) Qualifying Design utility rates and ROI 4) Design process a) Proper use of glycol b) Architecture 5) Controls a) system operating modes b) Energy savings goal c) Diagnostics 6) Economics first cost 7) Economics analysis - TRACE Trane , a business of Ingersoll Rand1engineers newsletter live Presenter Biographies Ice Storage: Design and Application Susanna Hanson | applications engineer | Trane Susanna is an applications engineer at Trane with over eleven years of experience with chilled-water systems and HVAC building load and energy analysis.

3 Her primary responsibility is to aid system Design engineers and Trane personnel in the proper Design and Application of HVAC systems. Her main areas of expertise include chilled-water systems and ASHRAE Standard She is also a Certified Energy Manager. She has authored several articles on chilled water plant Design , and is a member of ASHRAE SSPC Energy Standard for Buildings Except Low-Rise Residential Buildings. Susanna earned a bachelor s degree in industrial and systems engineering from the University of Florida, where she focused on building energy management and simulation. Lee Cline | senior principle systems engineer | Trane Lee is an engineer in the Systems Engineering Department with over 28 years experience at Trane . His career at Trane started as a factory service engineer for heavy refrigeration, helping to introduce the CVHE centrifugal chiller with electronic controls to the industry.

4 Following that Lee was a member of the team that kicked off the microelectronic building automation and Integrated Comfort Systems controls ICS - offering at Trane . He continues to push new unit and system control and optimization concepts into the industry. As a Systems Engineer Lee also has the opportunity to discuss HVAC system Application and control with owners, engineers and contractors on a daily basis. Lee has a Bachelors degree in Mechanical Engineering from Michigan Technological University. He is a Registered Professional Engineer in the State of Wisconsin. Paul Valenta |Sales Manager | CALMAC Mfg. Corp. Paul is a Manager at CALMAC Manufacturing Corporation with over 20 years experience in the ice energy field. CALMAC celebrated its 60th birthday in 2008 and has a long history of providing valuable energy saving products.

5 Paul s career at CALMAC started as a regional sales manager responsible for sales and distribution of ice storage systems in the Midwest. Without utility incentives and off peak rates, Paul specialized in developing partial ice energy storage applications in schools and offices and demonstrating their viability with life cycle costs. He has been involved in several hundred ice storage projects all over the world. Currently Paul is Marketing and Sales Manager for CALMAC. He has authored several articles on ice energy storage and rightsizing cooling plants with energy storage, is a member or ASHRAE and is a LEED Accredited Professional. Paul has a degree in Electrical Engineering from the University of Nebraska.
