SIMULTANEOUS SYSTEMS YOU CANT CONTROL WHAT YOU DON T MEASURE Presented By: Chris Medlock, Sales Manager March 8 th, 2017 --- Ohio All-In-One High Efficient Energy Solutions
Simultaneous System Fundamentals 1. Efficiently produce and transport energy to system. 2. Manage scalable flow and minimize excess pumping. 3. Actively assess utilization and storage throughout system. Targeting Net Zero Buildings
1. Transportation of Energy 1. Air Requires a large amount of conditioned space to run ductwork Fan Power excessive as net energy loop increases 2. Refrigerant 3. Water Can only share energy within a single circuit Compressor losses limits size 440 equivalent feet of line sets causes 20% reduction in compressor efficiency Moves energy 10 times more efficient than air Small diameter piping moves large amount of energy Easy to shut off flow to zones that are satisfied Easy to connect to onsite renewables like solar, ground loop, and bio-mass
2. Scalability, Flexibility, and Reliability 1. Modular Variable System Flows, Low cost redundancy 2. Zoning Improved efficiency, enhanced comfort, optimized sizing. 3. Variable Capacity High degree of capacity turndown
3. Optimization of Energy Generation and Utilization. 1. Maximize energy recovery Upgrade to High Efficiency WSHP s Integrate chilled beam, radiant floor, six pipe simultaneous HR chillers 2. Centralized system 3. Buffers and Storage Approaches Add Renewable Energy Hybrid Ground Loop Add other Renewable Energy (solar, wind, biomass) 4. Share across different parts of project Integrate non-hvac equipment: ice making machines, freezer cases, refrigeration cases, snow melt, ice rinks, process water, black water waste, grey water, sprinkler water
