The Montreal Protocol has scheduled the phasing out of controlled substances, including chemicals containing chlorine and bromine used as refrigerants, solvents, foam blowing agents, aerosol propellants, fire suppressants, and for other purposes. Ozone Layer Protection Ordinance (Cap. 403) 1989 gives effect to Hong Kong’s international obligations to control the manufacture, import and export of ozone depleting substances. Ozone Layer Protection (Controlled Refrigerants) Regulation 1994 requires the conservation of controlled refrigerants used in large scale installations and motor vehicles. Scheduled substances under the Ozone Layer Protection Ordinance are listed by the Environmental Protection Department. In addition to having suitable thermodynamic properties, the ideal refrigerant would be nontoxic, non-inflammable, completely stable, environmentally benign, readily available, self-lubricating, compatible with materials used in equipment, easy to handle and detect.
The U.S. Environmental Protection Agency provides information on suitable substitutes for ozone depleting substances, including refrigerants for various types of air-conditioning and refrigeration equipment, fire suppression, blowing agents, solvents, etc. U.S.EPA has developed and implemented regulations for management of ozone depletion substances (ODSs) in the United States. The regulations include programs that ended the production of ODSs and require the manufacturers to label products either containing or made with chemicals that have significant ODSs. Banning the usage of CFCs in refrigerants slows the ozone depletion and global climate change.
In BEAM Plus Manual, the credits of MA P2 (Use of Non-CFC Based Refrigerants) and MA8 (Ozone Depleting Substances) cover the concerns on usage of refrigerants. The air-conditioning and refrigeration equipments shall fulfill the following equation which determines a maximum threshold for the combined contributions to ozone depletion and global warming potentials: LCGWP + LCODP x 105 ≤ 775. The Client shall submit a report by a suitably qualified person giving details of the air-conditioning and refrigeration equipment installed; and demonstrating that the global warming potential and ozone depletion potential of the refrigerants used in equipment meets the specified requirement. Reference shall be made to refrigerant supplies and/or equipment manufacturer’s data together with guidance provided by recognised authorities such as ASHRAE, etc. In this seminar, the experts of refrigerants from ASHRAE will present the update on the relevant ASHRAE Standards as well as local development trends on new refrigerants.
ASHRAE Standard 15 & 34 – A Review and Update
ASHRAE’s key standards guiding refrigerant identification and usage have been revised to meet US governmental regulation and achieve improved performance. Standards 15 and 34 (2016 Edition) provide essential guidance to manufacturers, design engineers and operators who need to stay current with new air conditioning and refrigerating requirements.
Standard 34 (Designation and Safety Classification of Refrigerants) describes a shorthand way of naming refrigerants and assigns safety classifications based on toxicity and flammability data, while Standard 15 (Safety Standard for Refrigeration Systems) establishes procedures for operating equipment and systems when using those refrigerants. Standard 15 is one of ASHRAE’s oldest standards dating back to 1919. The purpose of Standard 15 is to specify safe design, construction, installation, and operation of refrigeration systems. All engineers that work with building mechanical systems should have a basic understanding of this Standard and for those engineers that work closely with refrigeration or chilling systems must have a deeper understanding of this standard and its requirements. This presentation will provide a review of Standard 15 and highlight recent changes to the standard. Common misapplications of the standard will be presented and discussed. In this session, the speaker also highlights the review and update of ASHRAE Standard 34.

Ph.D., P.E., ASHRAE Fellow Member & Distinguished Lecturer
Professor, University of Wisconsin-Madison
Douglas Reindl is a professor in the Departments of Engineering Professional Development and Mechanical Engineering at the University of Wisconsin-Madison. In addition, he is the founding director of the Industrial Refrigeration Consortium (IRC) at the UW. He received his B.S. in Mechanical Engineering Technology from the Milwaukee School of Engineering and his M.S. and Ph.D. degrees from the University of Wisconsin-Madison. He is a registered professional engineer in the State of Wisconsin and presently serves on the Board of Directors of the International Institute of Ammonia Refrigeration.
As faculty member at the University of Wisconsin since 1996, Professor Reindl has taught at all levels: undergraduate, graduate, and continuing professional development. Professor Reindl has developed an internationally-recognized series of professional development courses focused on industrial refrigeration systems with an emphasis on the safe use of ammonia as a refrigerant. Through the IRC, Professor Reindl works with some of the world’s leading food companies to improve the safety, efficiency, reliability and productivity of industrial refrigeration systems and technologies.
In addition to being an ASHRAE Fellow, Professor Reindl is also a member of the American Society of Mechanical Engineers, International Institute of Refrigeration, and the International Institute of Ammonia Refrigeration. He is a past recipient of ASHRAE’s Distinguished Service Award and the first recipient of ASHRAE’s George C. Briley Award for the best refrigeration article in the ASHRAE Journal. He is a past chair and member of ASHRAE’s Standard 15 committee – Safety Standard for Refrigeration Systems.
Professor Reindl has published 6 books and nearly 100 technical papers on topics including: industrial refrigeration, building mechanical systems, energy systems, indoor air quality, and solar energy.
Next-gen Technology Development for Low-GWP Refrigerants
The recent amendment to Montreal Protocol incorporating the control of hydrofluorocarbons (HFCs) has given a clear message to the industry in transitioning to next gen refrigerants of low global warming potential (GWP). ASHRAE is committed to a leadership role in responding to and reducing building Climate Change footprints. In support of this commitment, ASHRAE continuously advances the HVAC&R field by performing R&D guides and standards for designing systems that minimize energy use and reduce emissions of high GWP refrigerants.
Many common refrigerants with high GWP such as R404A, R410A and R134a started to see their successors, of which some options are still non-flammable but many become flammable. The HVAC&R industry has been actively developing next-gen technology around these new refrigerant options. This presentation will review the refrigerant applications in consideration of environmental, safety and energy performance.
