EUROHEAT & POWER CLIMESPACE PRESENTATION

Cooling – The New Market Dimension  Paris District Cooling Network

Cooling – The New Market Dimension CContents : GGrowing demand of cooling in Europe PParis Cooling Network AAdvantages and Environemental impact

Growing Demand in Europe  Market share of district cooling in Europe is between 2 to 3 TWh cooling  DC should be able to take 25 % share of market, which can be between 500 and 700 TWh in 2012  Why Such an interest ?  The case of Paris

Environnemental Comparison between Paris Network and Conventional cooling Climespace - 5 Sites - 1 Network Clients Conventional Cooling conventional Chillers  Studies asked to an independant university specialized in cooling solution (Armines)  Comparison : Electric consumption Frigorific gases impact Global Nuisances : Water Chemical Product Sanitary Risk Noise Visual Impact Local Nuisances : Architecture constraint Space saving

Comparison Between Climespace Network and owned conditionning system Method : Analyze of Climespace Network performance Electricity cnsumption Energy sold Frigorific gases leakage Analyze of Climespace Client profile and Consumption Comparison : ARMINES took figures of conventional chillers per client profile ARMINES made a model changing all our client putting adapted conventional chillers, corresponding to their consumption profile

Total Equivalent Warming Impact This index determines CO2 impact, taking into account: Direct effect: frigorific gases leakage (measure for CLIMESPACE, and estimation for conventional chillers) Indirect effect: Electricity consumption (Climespace consumption / performance data for conventional chillers)

Water and chemical products Consumption Water consumed by Climespace / consumption estimated for autonomous chillers with cooling tower

Global Environnemental Impact - 30%Frigorific Gas Impact Electrical Consumption - 20% TEWI (Total Equivalent Warming impact)-30% Water Consumption- 55 % Chimical Product - 80% Global Nuisances
