  15. 15. III. Why is District Cooling Environmentally friendly?  District Cooling helps the environment by increasing energy efficiency and reducing environmental emissions including air pollution, the greenhouse gas (GHG) carbon dioxide (CO2) and ozone‐destroying refrigerants.  Most Middle Eastern governments are parties to the United Nations Framework Convention on Climate Change. With most countries in the region having extremely high GHG emissions per capita, this issue will become increasingly important for government policy.  District Cooling can reduce annual CO2 emissions by about 1 ton for every ton of district cooling refrigeration demand served.
  16. 16. III. Why is District Cooling Environmentally friendly? Refrigerants  Varity of options available to replace CFC’s and HCFC’s  Most widely accepted replacement is a family of refrigerants  known as HFC’s (Hydro fluorocarbons),HFC‐134a  Regulated under the Kyoto Protocol which specifies reduction  targets for emission
  17. 17. IV. INTRODUCTION TO DISTRICT COOLING (D.C.) Industry History There are over 6,000 commercial district energy systems (heating and/or cooling) operating in North America, including all American military bases and some 2,000 universities and colleges The district energy industry has grown in the USA, Europe and Asia into a widely recognized, cost effective and environmentally friendly method of providing heating or cooling Japan has seen a four fold growth over the last decade Denmark four‐fold decade, fills nearly half of its heating requirements through district energy systems, and the UK has highlighted district energy as part of its strategy to reduce CFC emissions Famous landmarks, with district‐cooling systems include the Petronas Towers (Kuala Lumpur), the Pentagon (Washington) and La Defence (P i ) L D f (Paris)
  18. 18. IV. INTRODUCTION TO DISTRICT COOLING (D.C.) How District Cooling works  District Cooling is a utility which provides chilled water to customers buildings boundary via a metered and controlled process  The customer still has to do the internal building A/c work which constitutes of internal distribution piping, air side system & controls
