SINCE THE ENACTMENT OF THE OZONE LAYER PROTECTION ORDINANCE IN 1989, MEASURES HAVE BEEN TAKEN TO MINIMISE THE RISK OF CFC ESCAPING TO THE ATMOSPHERE INCLUDING THE USE OF RECYCLING ANCILLARY EQUIPMENT.
PLANTS OPERATING WITH REFRIGERANTS OTHER THAN CFC HAVE BEEN
INSTALLED.
3.
THE SECRETARY SAID THESE INCLUDED THE HCFC CENTRIFUGAL CHILLERS THE KAI TAK AIRPORT AND THE WANCHAI TOWER
AND THE LITHIUM BROMIDE ABSORPTION CHILLER AT QUEEN MARY HOSPITAL.
AT
THE HCFCS HAVE A SIGNIFICANTLY LOWER OZONE DEPLETION AND GLOBAL WARMING POTENTIAL.
IN THE ABSORPTION SYSTEM, WATER IS USED AS A REFRIGERANT WHICH IS CFC-FREE.
то
IN THE LONGER TERM, MR BLAKE SAID CONSIDERATION HAD BEEN GIVEN REPLACING ALL EXISTING INSTALLATIONS BY HCFC-ZE AND ABSORPTION
CHILLERS.
HE SAID A CAPITAL EXPENDITURE OF ABOUT $500 MILLION AND AN ADDITIONAL ENERGY COST OF $30 MILLION A YEAR WERE REQUIRED IF HEFC- 22 WAS TO BE PURSUED.
THE CORRESPONDING CAPITAL COST AND ADDITIONAL ENERGY COST PER YEAR WERE $920 MILLION AND $490 MILLION FOR ABSORPTION CHILLERS.
THE SECRETARY SAID A TWO-YEAR RE-FITTING PROGRAMME WAS EXPECTED FOR EITHER OPTION.
ADDITIONAL PLANT ROOM SPACE WOULD INVARIABLY BE REQUIRED, WHICH MIGHT NOT PERMIT THE REPLACEMENT OR MODIFICATION OF THE PLANTS IN ALL CASES.
