Comparison of Ozone destroy factor and earth warmth factor by coolants

Coolant CFC12 HCFC HFC134a
Ozone destroy factor 1.0 0.055 0.0
Earth warmth factor
(CO2=1.0)
8,100 1,500 1,300
  • (Note: data accumulated 100years)

In spite of no Ozone destroying, HFC134a influences on earth warmth if the coolant is emitted in atmosphere. It is obligated to recycle and to destroy the coolant by specific contractors.
