Update on ASHRAE refrigerant activities - B. Olesen - ASHRAE

  1. 1. Update on ASHRAE Refrigerant Activities for Mostra Convegno Expocomfort March 15, 2018 Presenter: Bjarne W. Olesen | 2017-2018 ASHRAE President Shaping Tomorrow’s Built Environment Today
  2. 2. 56,000+ members 130+ countries 11,000+ outside N.A. 14 Regions 180+ Chapters 300 Student Chapters Industry Classification  Consulting engineers  Contractors  Manufacturers  Manufacturing representatives  Government, health and education  Design build  Architects U.S./Canada (45,000+) Global (11,000+)
  3. 3. ASHRAE contributed to the successful effort to phase out the ozone-depleting CFC and HCFC refrigerants ASHRAE’s Interest
  4. 4. ASHRAE Initiatives on Refrigerants Overview  Innovative technologies and research enables the HVAC&R industry to create a more sustainable built environment  Nowhere are such rapid changes occurring as in the flammable refrigerants field  Regulations – along with an ever-growing concern for the environment – have made flammable refrigerants one of the more prevalent topics for the HVAC&R industry within the past five years
  5. 5. Low-GWP Alternatives Identify low-GWP alternatives, taking into consideration the following criteria: • Energy efficiency • Safety • Compatibility • Cost
  6. 6. ASHRAE Initiatives on Refrigerants Several promising refrigerants have been identified.These include hydrocarbons such as:  Propane (R290)  Isobutane (R600a)  Ammonia (R717), R32  And other low GWP HFO’s.  Exploration and research must continue  Alternative lower GWP refrigerants would ideally provide the same – if not better – energy performance as current refrigerants
  7. 7. ASHRAE Research on Flammable Refrigerants
  8. 8. ASHRAE-RP 1806 Flammable Refrigerants Post-Ignition Simulations and Risk Assessment Update (ASHRAE-RP 1806)  12-month project  Findings will help the industry better understand the severity of events where flammable refrigerants are being ignited  Results will help refine the accuracy of safety standards currently being developed for flammable refrigerants and the associated building codes
  9. 9. ASHRAE-RP 1807 Guidelines for Flammable Refrigerant Handling, Transporting, Storing and Equipment Servicing, Installation and Dismantling (ASHRAE-RP 1807) Three objectives:  Review existing requirements/practice for safe handling of flammable refrigerants  Review technician licensing or certification requirements  Propose requirements for servicing and installing HVAC&R products using flammable refrigerants
  10. 10. ASHRAE-RP 1808 Servicing and Installing Equipment using Flammable Refrigerants:Assessment of Field-made Mechanical Joints (ASHRAE-RP 1808)  Last of three high-priority projects led by ASHRAE  Goal is to help determine whether common types of joints other than brazed or soldered joints should or should not be allowed inASHRAE Standard 15.2, and other relevant codes and standards
  11. 11. Additional Research Efforts  Benchmarking Risk by Real Life Leaks and IgnitionsTesting (AHRTI 9007)  Investigation of Hot Surface Ignition Temperature (HSIT) for A2L Refrigerants (AHRTI 9008)  Leak Detection of A2L Refrigerants in HVAC&R Equipment (AHRTI 9009)  Determination of Setting Charge Limits for VariousTypes of Equipment Employing Flammable Refrigerants (DOE/ORNL)
  12. 12. ASHRAE Standard 15-2016, Safety Standard for Refrigeration Systems  Directed toward the safety of persons and property on or near the premises where refrigeration facilities are located  Features up-to-date research designed to improve the safe design, construction, installation and operation of refrigeration systems  Gives a method for determining the amount of refrigerant in a given space that, when exceeded, requires a machinery room
  13. 13. ASHRAE Standard 34-2016, Designation and Safety Classification of Refrigerants  Describes a shorthand way of naming refrigerants and refrigerant blends  Assigns safety classifications based on toxicity and flammability data  Primary components include: ⁻ Numbering and designation of refrigerants ⁻ Safety group classifications ⁻ Refrigerant concentration limits
  14. 14. Education andTraining  ASHRAE is leading the way of addressing flammability in refrigerants in education and training  Courses that explains the classification system by whichASHRAE assigns refrigerants  Courses explains process described in ASHRAE Standard 34 that results in a standardized system of assigned refrigerant numbers and well-defined safety classifications, including toxicity and flammability ratings
  15. 15. Education andTraining • Two year “twinning” project (2018-2019) • Jointly build capacity of National Ozone Officers (NOOs) and national energy policymakers (NEPs) • Linking energy efficiency with Montreal Protocol objectives in support of the KigaliAmendment UN Environment • Kigali Cooling Efficiency Programme
  16. 16. Education andTraining Energy-Efficient and Climate-Friendly Refrigeration and Air Conditioning • TwinningWorkshop • Explore opportunities to improve the performance of cooling products in their markets. • Two Days - 11 -12 April 2018, Beijing, China UN Environment • Kigali Cooling Efficiency Programme
  17. 17. Education andTraining Sound Management of Refrigerants The course consists of seven lessons:  Lesson 1: Environmental Issues and ASHRAE Standards  Lesson 2: RefrigerantTerminology and Numbering Systems  Lesson 3: Refrigerant Recovery, Recycle, and Reclaim (3 R’s)  Lesson 4: Refrigeration System Lubricants and Applications  Lesson 5: Service and Installation Issues with various refrigerants and related equipment  Lesson 6: Safety with Refrigerants,Tanks, and Lubricants  Lesson 7: U.S. EPA and International Refrigerant Handling Laws
