PHASING OUT HCFC
Bertrand MARTIN CEO Climespace

Regulation (EC) n2037/2000 (1/2)

• The goal is to phase out Ozone Depleting
  Substances (ODS) like CFC (1)
• and HCFC (2).

• CFC Chlorofluorocarbon
• HCFC Hydrochlorofluorocarbon
• HFC Hydrofluorocarbon

Regulation (EC) n2037/2000 (2/2)

• Table of dead-lines

Paris Network

• Comparison of refrigerant between autonomous
  chillers in France and Climespace.

5
District Cooling Network advantages in term of
refrigerant

• Installed Power reduced compare to autonomous
  installation
• None simultaneous consumption (Paris Connected
  Power 270 MW of cooling / Installed Power 230 MW
  of cooling)
• Use of water and Ice Storage (17 MW water storage
  and 40 MW ice storage)

• Biggest industrial installation witch permit
  to put in place efficient technologies
• Chillers between 3 to 15 MW of cooling
• Absorption chiller
• Water and Ice Storage
• Free Cooling
• Lower condensing temperature by the use of river
  cooling

6
Network advantages in term of
refrigerant

• Flexible approach of client conception
• Possibility to increase power without new
  chiller.

• Better management of installation
• Big industrial installation
• Leakage detection of refrigerant
• Day to day performance analysis

The regulation is harder for the District Cooling
Network and the control is easier than for the
autonomous chillers.

Exemple of reduction of refrigerant compared
to autonomous chillers

• A compared analysis between 2 DCN in Paris and
  autonomous installation in term of direct impact
  due to
• Less redundancy
• Biggest chillers
• Use of river cooling
• Ice and chilled water storage
• Refrigerant management

• CLIMESPACE - 72 of refrigerant consumed
• ENERTHERM - 63 of refrigerant consumed

8
Other benefits

• INDIRECT effect
• Less electrical consumption which permit to limit
• the Warming Impact whatever the refrigerant
