F) REFRIGERANT APPLICATIONS
G) Alternative Halocarbon Refrigerants
1) R-1234yf (HFO-1234yf) will replace R-134a in mobile
air conditioning. The US market started in 2013.
ODP = Zero , GWP = 4
2) R-1234ze (HFO – 1234ze) will replace R-134a in air
conditioning chiller applications and will be used as
insulation foam blowing agent. USEPA have approved
its use in 2015. ODP = Zero, GWP = 6
3) R-1234yf (HFO-1234yf) will replace R-134a in mobile
air conditioning. The US market started in 2013.
ODP = Zero , GWP = 4
4) R-1234ze (HFO-1234ze) will replace R-134a in air
conditioning chiller applications and as insulation foam
blowing agent effective 2015 as approved by the US EPA.
ODP = Zero , GWP = 6

HOW MANY CHILLERS ARE
INSTALLED IN METRO MANILA ALONE?
IN 2010, THE WORLD BANK CONDUCTED A
SURVEY ON INSTALLED CHILLERS IN MALLS,
HOTELS, HOSPITALS AND COMMERCIAL
BUILDINGS. THOSE IDENTIFIED HAVE 1,400
CHILLERS WITH MINIMUM CAPACITY OF 300 TONS
OF REFRIGERATION. THE TOTAL NUMBER IS ABOUT
6,000. THE ANNUAL MARKET GROWTH IS 5%.

Safety Classification of Refrigerants
HOW MUCH REFRIGERANT
DOES AN AIR CONDITIONING
SYSTEM NEED?
ABOUT 1.7 KILOGRAMS PER TON
HOW MUCH REFRIGERANT
IS LOST YEARLY DUE TO LEAKS?
1% FOR NEW EQUIPMENT, 5 TO 10% FOR
OLD EQUIPMENT
HOW MUCH CO2 EMISSION
DOES THE PHILIPPINES RELEASE?
106.5 MILLION METRIC TONS IN 2015 GROWING
AT 8.6 PERCENT PER YEAR
