Reducing Ozone Depletion

1
Reducing Ozone Depletion

• HCFC-22
• Contains chlorine, which can deplete the ozone
  layer
• Must be phased out of new equipment by 2010
• R-410A
• Environmentally friendly
• Meets all current and future government
  regulations
• Available from most major air conditioning
  manufacturers today

Ozone Overview

• Ozone layer surrounds the earth
• Filters harmful UV light
• Ozone depletion
• Higher levels of UV light come through
• Causes cancer, destroys marine life and crops
• HCFC-22 refrigerants contain chlorine gas
• Chlorine gas can destroy ozone molecules
• R-410A will not damage the ozone

R-410A The Proven Residential Choice

• The best, long-term solution for cost and
  efficiency
• Higher efficiency and better Total Equivalent
  Warming Impact (TEWI)
• Superior reliability
• Near silent operation
• Improved dehumidification
• Enhanced heat pump performance
• Lower cost over life of the system

R-410A vs. HCFC-22

• There is a difference
• R-410A operates at higher pressures but lower
  temperatures
• Contractors should be trained before installing a
  system
• Joint brazing quality is important
• Uses polyol ester (POE) oil, which is sensitive
  to moisture
• Moisture control and system cleanliness is key

The R-410A Summary

• Here today, growing tomorrow
• R-410A is the optimal replacement for
  chlorine-containing HCFC-22
• Chlorine-free
• Excellent cooling power
• Environmentally sound
• Energy efficient
• The U.S. industry changeover is accelerating
