Conversion of R290 in Chillers and Ducted Air Conditioners

  1. 1. Iwan ChandraAICOOL - Indonesia
  2. 2. • Background• Basic Design – Safety Aspect – Components Selection• Production & Testing Facilities• Installation on Site• Customer Approach
  3. 3. Climate Change & Global Warming
  4. 4. • Safety Standard – EN 378 : Refrigerating systems and heat pumps Safety and environmental requirements – ISO (DIS) 5149: Refrigerating systems and heat pumps - Safety and environmental requirements – IEC 60335-2-40: Particular requirements for electrical heat pumps, air-conditioners and dehumidifiers – SNI-06-6500-2000 – Refrigerant application for fixed Installation
  5. 5. • Safety Aspect – Unit Construction must be consider for avoid Triangle of Fire Condition occurs. Eliminate at least one factor, preferable two factor i.e Ignition and Refrigerants concentration. – Charge Limitation for Direct system (Refrigerant circulated to the Room) – Electrical control box with ATEX Spec. – All Control & Accessories without Sparks
  6. 6. • Concern to component w/ large amount of Refrigerant – Condenser Coils – Separate with other component & parts – Free space at bottom because R290 gas heavier than air. – Good Ventilation
  7. 7. • Eliminate for all electrical component that have potential to produce sparks, ensure : – Placed on appropriate enclosure – Replace with solid state contact or explosion proof spec – Locate externally
  8. 8. • Compressor Anti Static Electric Box Cable Conduit
  9. 9. • Heat Exchangers. According to minimize the charge, select the smaller volume.Conventional Fins and Tube, Advanced HX with 40% Reduce Volumecan Maximizing the Airflow to Reduce Size Microchannels Technology for Condenser
  10. 10. • Heat Exchangers. According to minimize the charge, select the smaller volume.Shell n Tubes Coolers for Chillers Braze Plate Heat Exchanger BPHEVery Large of Volume 85 % Reduction in Volume of S&T
  11. 11. • Other Parts & Accessories Must be specialized For HC Refrigerants
  12. 12. • Using HC Refrigerant will take changes to safety of production line
  13. 13. • Give Warning to some area which work with HC Gas
  14. 14. • Layout of Safety Controlled Area
  15. 15. • Refrigerant Handling and Storage• Rules for R290 refrigerant cylinders usually same as any flammable gas cylinder – Store outside – follow local regulations for LPG, if none at least: ☺ In a locked cage ☺ At ground level (never below) ☺ Away from air intakes to building ☺ Remote from ignition sources No smoking
  16. 16. • Location & Positioning would generally be within the requirement of Relevant Standards – Located Outside (Open Air), unit should be positioned to avoid refrigerant leaking into the building
  17. 17. – Located Inside in a Machinery room, occupied space, or within a ventilated space enclosure, specified in EN 378-1
  18. 18. • Training – Design engineers technical and safe handling – Production workers basic safe handling – Production technicians thorough safe handling – Service technicians thorough safe handling
