F-Gas – Phase Down
Phase Down
Mechanism
• What is your Strategy for Change?
It should include...
• Refrigerant leak / charge reduction
• Educate your team and your customers
on this change
• Improve your understanding of the low
GWP alternatives to R404A
• Understand the minor differences in
‘how they are applied’
F-gas Regulations will
Challenge our Industry
Opportunities
• Become more comfortable with the
differences  glide / flammability / high
pressures / different system technologies
etc..
• Refrigerant choice – STOP using R404A
wherever possible
• Mindset - Change provides Opportunities for
your business

 R448A (best) and R407F (better) provide the highest combined energy efficiency
 Due to lower discharge temperature, R448A is less likely than R407A or R407F to require liquid injection**
**Requirements will vary depending on the actual operating conditions.

BETTER BEST
Performax LT (R-407F) is preferred option
• Already commercial
• Homologated by most components
manufacturers
• Proven experience in commercial, industrial and
food service applications over Europe
• Closer cost to R-404A than Solstice N40
Solstice N40 (R-448A) could be interesting if:
• Further GWP reduction is desired
 Environmental goal
 Tax country
• Slight improvement of Tdis vs R-407F is required
 Solstice N40: Tdis still higher than R-404A
 Solstice N40: Tdis still lower than R-22

HDR110 (GWP<150): Self-Contained System Evaluation
 ASHRAE 72 standard test:
 3/4 HP Reach-in R404A Freezer placed in a chamber at 25°C
Cabinet volume filed with glycol/water test simulators and frozen food
 Near drop-in test of HDR-110:
 TXV was slightly adjusted to provide appropriate superheat
 No oil change required. Typical charge optimization carried out
Evaporator position inverted to get counter-flow configuration
