yun.. nasapul ni otep!.....

[sauman]

kaso nasa PINAS tayo e kung saan naglipana ang mga epal sa mga ahensiya ng gobyerno. Lalo na diyan sa LTO at DOTC, di na sila nadala dun sa kapalpakan nila sa EWD dati. Pag may mga naisip na paraan implement kaagad without a thorough study.

Saan nila dinala ang R12 mo? Most shops will just vent it into the atmosphere. I doubt kung may R12 recovery equipment sa Pilipinas.

The AC shop that I go to has a recovery system for both R12 and R134a.

Time to replace those old car aircon units

The Land Transportation Office (LTO) is set to reject the registration of all vehicles, covering 1999 models and older, which do not use non-chlorofluorocarbon (CFC) agents in their car’s air-conditioning unit starting Jan. 1, 2006, the Department of Environment and Natural Resources (DENR) announced yesterday.

Environmental Management Bureau (EMB) Assistant Director Fernandino Concepcion said that the move is part of the government’s scheme to phase out the use of ozone depleting substances (ODS) in the country in fulfillment with the 1988 Montreal Protocol on Substances that Deplete the Ozone Layer.

"Vehicles with air-conditioning must shift to the use of the ultimate alternative for CFC, such as HFC (hydroflourocarbon) before that time. Otherwise, they will not be allowed to ply our roads by the LTO," Concepcion said. "The continuous use of CFCs in air conditioning systems of vehicles is akin with violations to the provisions of the Clean Air Act."

When the Philippines became a signatory to the Montreal Protocol, the country committed itself to phase out the importation and consumption of CFCs in all sectors — manufacturing and servicing.

The Protocol was concurred by the Philippine Senate on March 21, 1991.

The Philippines is considered an "Article 5" country under the Montreal Protocol, thus, it was given a grace period of 10 years to phase out ODS consumption.

The Philippines is expected to have complete phase out of the importation and use of CFC, or freon, in the service and manufacturing sectors by 2010.

As this developed, Elvira Pausing, project manager of the National CFC Phase-Out Plan (NCPP), said that the country is ahead of schedule in the agreed timetable for phasing out ODS in developing countries.

She said that a 50 percent phase out of CFC consumption scheduled for 2005 had been met last year. By 2007, the Philippines must have phased out CFC consumption by 85 percent.

CFC-12, or freon, is best known as a chemical substance that cools refrigerators and car air-conditioners. It is also used as blowing agents for foams, propellant for aerosol and metered-dose inhalers as well as cleaning agents for computer circuits.

The service sector accounts for some 75 percent of CFC consumption in the country.

Half of the 75 percent is used to service car air-conditioners while the remaining 26 percent service household appliances like refrigerators and air-conditioners.

The manufacturing sector accounts for 25 percent of CFC consumption.

"We will be able to phase out the use of CFC in the manufacturing sector this year while our target for the phaseout in the use of CFC in the service sector will be for the next five years," Pausing told reporters.

The NCPP is the fourth and biggest project under the DENR-EMB’s Philippine Ozone Desk. It has a budget of $10.58 million with the assistance of the Multilateral Fund for the Implementation of the Montreal Protocol through the World Bank.

Part of the NCPP project is the Voucher System, a financial grant assistance to properly equip service establishments to recover and recycle CFCs.

Under the program, the DENR-EMB will distribute P75,000 worth of tools and equipment to service enterprises.

Tools and equipment include portable leak detectors, recovery and recycling machines, vacuum pumps and meters, electronic weighing scales, nitrogen regulators with gauges and electronic thermometers.

The tools and equipment can be purchased at any EMB-qualified supplier.

Eligible applicants for the grant include CFC service shops and providers that are registered with any appropriate government agency like the Department of Trade and Industry (DTI) and with TESDA-certified technicians.

Pausing said the Voucher System has a budget of $1 million and will be implemented by the DENR-EMB in cooperation with the Land Bank of the Philippines, DTI and TESDA.

Also, orientation seminars geared at increasing understanding of refrigeration and air-conditioning as well as mobile air-conditioning service shop owners and technicians on the NCPP are now underway.

"We are giving the service shops the grant for the tools and equipment to help them correct their old ways and adopt proper repair and maintenance, servicing, and installation systems," Pausing said.

Prior the NCPP, the DENR-EMB embarked on the phaseout of another ODS — methyl bromide which is used in fumigation.

Dubbed as the National Methyl Bromide Phase-out Strategy, the project aims to gradually reduce and eliminate a total of 9.03 tons of methyl bromide and ensure that there are eventually viable and permanent alternatives and alternative approaches to maintain the phaseout.

Based on the agreed timetable for phasing out ODS, the Philippines must totally phase out the consumption of methyl bromide by 2015.

Other ODS which the Philippines must totally phase out by 2010 are carbon tertrachloride (CTC), and halons; by 2015, methyl chloroform; and by 2040, hydrofluorocarbon (HCFC).

gudam. i just read this article this morning i'd like to share with you.
affected kasi ako nito, panibagong gastusin na naman pala ito.

Cars using CFC banned next year


By RONNIE E. CALUMPITA, The Manila Times Reporter

Starting next year all vehicles manufactured before 1999 whose air-conditioning units still use chlorofluorocarbon (CFC), an ozone-depleting substance, will not be allowed to register with the Land Transportation Office, the Department of Environment and Natural Resources said Tuesday.

Elvira Pausing, program manager of the Philippine Ozone Desk of the Environmental Management Bureau, said the crackdown is part of the country’s compliance with the Montreal Protocol on Substances that Deplete the Ozone Layer. The agreement, signed by 188 countries on September 16, 1987, binds signatories to reduce and eventually phase out the production and consumption of ozone depleting substances.

She urged car owners whose cars’ air-conditioning units use CFCs to replace this chemical with HFC-134a or HFC-125 and HFC-143a.

CFC, commonly known as freon and hydrochlorofluorocarbon, are also used as cooling agents for refrigerators.

"We also urge vehicle manufacturers to use alternatives cooling agents such as HFCs to meet the Montreal agreement," Pausing told reporters in Quezon City.

Fernandino Concepcion, EMB assistant director, said the Philippines has met the 50-percent reduction of CFC consumption in 2004, a year ahead of the schedule. The Philippines is bound by the agreement to reduce its CFC consumption by half at the end of 2005.

From 1995 to 1997 the country’s average consumption level of CFCs was 3,018 ozone depleting potential metric tons. As early as last year, Concepcion said, the Philippines has reduced its consumption by 1,509 ODP MT.

"By 2007 we should reduce it by 85 percent. By 2010, we must meet the scheduled total phaseout of CFCs," he said.

The ozone desk was established in 1992, a year after the Senate ratified the Philippine commitment to the Montreal Protocol. The agency provides technical and financial assistance to car, air-condition and refrigerator manufacturers to meet the scheduled reduction of CFC use.

palit compressor ba ito? o palit freon lang?
paki-explain naman kung paano/ano ang gagawin sa present aircon unit ko just to comply with this new ordinance baka maloko ako ng aircon shop dito. wala ring idea yung mga officemates ko dito e.
thanks!

[nicko]

Dont worry about it, Panibagong gimik lang yan ng LTO to make money. Just like the emission test Just think of all the FX taxis and ordinary taxis with the regular freon. and how would they now what freon are you using.

[jim]

final na ba ito??? hmmmmmnnnn palit tubo, dryer at hoses ako pag nagkataon. buti na lang yung compressor ko bago na.

[orly_andico]

imho lahat naman ng cars made after 1994 are R134a na eh.... mine is 1993 nga and it's already R134a.

nag pa-convert na ko from R12(?) to 134. year 1997 pa so not sure kung may bagong technique after this. i decided to do this kasi sira naman talaga na yung a/c nung car and the cost is just incrementally higher due to new tubing and the more expensive freon. I used the car for another 2 years, OK naman - except for 1-time additional freon and o-ring change and coupling tightening.

1. replace (defective) evaporator and valve
2. replace (defective) dryer
3. oil change for the compressor
4. replace tubing (alumnimum)
5. of course cleaning/vacuum and freon 134

[SunTzu]

and how would they now what freon are you using.
