When architect asks what’s new
        in rooftops……….


• High Efficiency Rooftop Unit

• Flexible Design Options

• Innovative New Features
Packaged DX Rooftop Units




 What’s
 new?




 Nothing new here.
Variable Speed Chiller
               Technology




Has your rooftop kept up with chiller technology?
Why Variable Speed?



    84% time
    Below 60% Load
Scroll Compressors
Digital Scrolls
Variable Speed Scroll
• High EER – part load
• Controls to set point
• Eliminate Hot Gas By-
  pass
• Inverter provides oil
  management
• Fewer Starts/Stops
• Capacity Range 50% to
  150% (30 to 90Hz)
Variable Speed Scrolls
Variable Speed Savings
                              AC Power Consumption vs Ambient


 Very limited

DAC Annexair Overview 2-2013

  • 1.
  • 3. When architect asks what’s new in rooftops………. • High Efficiency Rooftop Unit • Flexible Design Options • Innovative New Features
  • 4. Packaged DX Rooftop Units What’s new? Nothing new here.
  • 5. Variable Speed Chiller Technology Has your rooftop kept up with chiller technology?
  • 6. Why Variable Speed? 84% time Below 60% Load
  • 9. Variable Speed Scroll • High EER – part load • Controls to set point • Eliminate Hot Gas By- pass • Inverter provides oil management • Fewer Starts/Stops • Capacity Range 50% to 150% (30 to 90Hz)
  • 11. Variable Speed Savings AC Power Consumption vs Ambient  Very limited operation at peak  Highest energy savings where the 40% Less unit operates the Energy most WATTS  Decreased sound 90% Less Energy at low speed Fixed Speed Compressor Typical Performer VSH Unit Low Intermediate High Peak Ambient Temperature
  • 12. Variable Speed Part Load EER vs % Load 16 15 14 EER 13 EER_100% 12 EER_75% 11 10 Variable Speed Fixed EER increases as load decreases
  • 13. Can we do more? V3 Technology • Variable Speed Compressors • Variable Speed Condenser Fans • ECM fan technology • VFD Driven Direct Drive Supply & Return Fans
  • 14. V3 Technology Raises the bar • Higher Efficiencies 20.9 EER at low loads 15.6 EER at mid load • Load matching • Better Turndown
  • 15. What about Heat Pumps? • Annexair developed • Water Source Cooled / Heat Pump unit • Packaged with any Annexair Product – ERU / AHU / MAU • 10-84 tons
  • 16. Packaged WSHP  All units are piped, wired & charged w/R410a  Factory tested  WSHP integrated within the cabinet  Multiple Staging  Modulating hot gas reheat
  • 17. Product Categories • Semi Custom Design • Flexible layouts • Start with a blank sheet • Basic unit catalog
  • 18. Product Line Product Categories Single device Single device Dual device wheel/ heat pipe fixed plate Energy Recovery Units With energy recovery Standard MAU Makeup Air Units Air Handling Units Water Cooled With integrated water Packaged Units Air Cooled source heat pump
  • 19. Energy Recovery Units Enthalpy Wheel Units –Total Energy Recovery Heating options Cooling options - Hot water - DX - Steam - Chilled water - Indirect gas fired - Electric Wheel effectiveness: 70-80% (not all available configurations shown)
  • 20. Heat Recovery Units– Sensible Heat Recovery Fixed Plate Units Heating options Cooling hot water, steam, electric,options chilled water direct or indirect gas fired DX Plate effectiveness: 60-70% (not all available configurations shown)
  • 21. DOAS Energy Recovery Units Dual Device Units
  • 22. What’s the Next New Thing?
  • 24. Thermo-Composite unit Features Real Thermal-break panel Thermal-break framing system Hygienic construction
  • 25. Thermo-Composite unit Panel Details 2” R-14 Foam Aluminum foil finish Insulation Inner & outer • Foam is made of special polystyrene with 30% recycled content • Foam is Greenguard certified • Patent pending
  • 26. Thermo-Composite unit Framing Details Insulated intermediate profiles Thermal break nylon insert – eliminates risk of Extruded anodized condensation aluminum profiles for unit perimeter only
  • 27. Thermo-Composite unit Specifications • Fire Resistant, UL 723 / ASTM E84, Class 1 • 3000 hr salt-spray resistant • UV resistant (PVDF coating) • Chemical resistant • Moisture & Chlorine resistant
  • 28. Thermo-Composite unit Advantages vs Standard Units • Panel weight is 55 % lighter – Unit weight is up to 30-45 % lighter • Lifetime unit warranty against corrosion on the unit casing • No through metal, true thermal-break construction • No rusting & sweating possible • Hygienic construction
  • 29. Thermo-Composite unit Electrical Features Annexair standard electrical panel with pre-punched power entrance Finger safe fuse blocks
  • 30. Thermo-Composite unit Water Source Heat Pump •Integrated WSHP with variable speed compressor
  • 31. Thermo-Composite unit Improved piping New welded flexible hose piping which eliminates all sources of vibration. Performs better then standard vibration absorbers. New anti-sweat paint applied on the bottom section of the compressor which reduces the amount of condensation produced. Our new 100% made aluminum base for WSHP section with easy access to all parts
