Energy and Atmosphere 4 - Enhanced Refrigerant Management
February 13, 2008 – 9:23amIntent:
- Reduce ozone depletion potential (ODP) and global warming potential (GWP)
- Support early compliance with EPA Montreal Protocol
Implmentation:
- Quick Information:
- refrigerant comparison
- CFC (high)
- HCFC (medium)
- HFC (low)
- efficiency of HFC is less than HCFC
- refrigerant comparison
- OPTION 1: do not use ANY refrigerants
- OPTION 2: use refrigerants and HVAC that minimizes or eliminates emission of compounds that cause ozone depletion & global warming
- do not install fire suppression systems with ozone depleting substances
- use natural refrigerants: water, carbon dioxide, ammonia
- use refrigerants with low ODP & GWP
- minimize Lr (leakage rate)
- use equipment with efficient Rc (refrigerant charge)
- use equipment with “long service life“
Code:
- Clean Air Act 1990
- EPA Montreal Protocol 1987
Submittal Phase:
- design
Extra Credit:
- none

This is one of those Credits that claims to have NO reference standard and goes into pretty specific detail in the implemenataion where you definitely need to comply with the Clean Air Act Title 6 for the leakage reporting
and the Montreal Protocol is mentioned also in the Implementation , sub heading Select with low ODP and GWP-they are trying to address the dilemma that a low ODP refrigerants are not the most energy efficient, and cause more global warming… technologies are hoped to be in place where they agreed to phase out CFC and HCFC by 2030 so Get Designing!

Will the use of natural refrigerants such as CO2, ammonia, water; work for Option #1. I see them cited in the ‘Do Not Use Refrigerants’ section on p219 v2.2 but it doesn’t really clearly specifiy.
