1 District Cooling &District Heating - Danish Experience PRESENTATION BY CRISPIN MATSON 29 November 2017

2 RAMBOLL IN BRIEF Independent engineering and design consultancy and provider of management consultancy Founded 1945 in Denmark 12,300 experts Over 300 offices in 35 countries Significant presence in the Nordics, North America, the UK, Continental Europe, Middle East, Asia, Australia, South America and Sub-Saharan Africa EUR 1.1 billion revenue Owned by Ramboll Foundation Services across the markets: - Buildings - Transport - Environment & Health - Water - Energy - Oil & Gas - Management Consulting

3 SPECIAL COMPETENCIES District Heating Energy-From- Waste Power Power Transmission Offshore Wind Within these five areas, we provide a one-stop shop of services based on unique knowhow and experience gained from a large number of projects, unmatched by other consultancies

4 SELECTED ENERGY SYSTEMS PROJECTS Clapham Park Greenwich Peninsula LCE Gospel Oak, Camden District Heating Wembley Energy Masterplan & District Heating Client advisor for Metropolitan Housing Association 2400 new dwellings to be built over in a phased devlopment ESCO negations ongoing for design, build, own and operation of DH network Development consisting of over 10,000 new homes, 320,000m2 of commercial space, and 18,000m2 of retail space. Heat network and energy centre concepts were developed through a detailed phasing option analysis. A district heating scheme using source waste heat rejected in the exhaust gases of the existing turbine in the royal free hospital 1,500kw of energy generated from exhaust gases A network serving six blocks of residential dwellings Detailed design of 2 district heating systems South West Lands and East Lands development in Wembley, London Borough of Brent. Concept and RIBA Stage 2 and Technical Design RIBA Stage 3 for the complete district heating design and energy centre, distribution pipework and substations in each block

13 COPENHAGEN MARKETS COMBINED HEATING AND COOLING 2 chillers + 2 heat pumps Providing cooling for fresh fruit, flow and vegetable market hall in Copenhagen. Waste heat from cooling plant is enhanced and add to district heating for the city. Heat sink: district heating water 45⁰C to 75⁰C Combined COP (Heating + Cooling >3.60) 2.3 MW of heating 3.2 MW of cooling Heat source: Glycol/water 16⁰C to 6⁰C Installed by ICS 13

17 FACEBOOK - ODENSE New 500,000m2 data centre 25 MW heat pumps supplying cooling at 25 deg C. Heat pumps reject heat at 70 deg C into local DH network run by Fjenvarme Fyn 100,000 MWhr per anum of heat recovered Heat pumps powered by 100 % renewable electricity

18 BUNHILL PHASE 2 COMMUNUAL HEAT NETWORK EXTENSION & HEAT RECOVERY

19 BUNHILL PHASE 2 HEAT AND POWER Concept design to cut carbon emissions and fuel bills in the borough, yielding both financial and environmental benefits by generating heat and power locally in Islington, London Take heat from the exhaust air from the London Underground and heat from a UK Power Networks transformer cooling system. This low grade and variable heat source will be upgraded through the use of heat pumps to meet the Council s aim of providing more heat to their homes whilst keeping the energy costs affordable

20 BUNHILL PHASE 2 HEAT PUMP (COMPRESSOR) CAPACITY CONTROL System layout of heat source 1 heat pump System layout of heat source 2 heat pump

21 BUNHILL PHASE 2 HEAT PUMP SIZE Temperature measurements from Waste Heat Source 1

22 BUNHILL PHASE 2 HEAT PUMP SIZE Temperature measurements from the windings of the transformer unit

23 HEAT RECOVERY FROM LONDON UNDERGROUND warm air 24⁰C 30⁰C 700 kw Underground Ventilation shaft 1000 kw 23

24 BUNHILL PHASE 2 HEAT NETWORK Concept design to cut carbon emissions and fuel bills in the borough, yielding both financial and environmental benefits by generating heat and power locally in Islington, London Take heat from the exhaust air from the London Underground and heat from a UK Power Networks transformer cooling system. This low grade and variable heat source will be upgraded through the use of heat pumps to meet the Council s aim of providing more heat to their homes whilst keeping the energy costs affordable

25 CONCLUSION Large scale heat pumps can be successfully used with large scale DH networks District Heating and District Cooling can combined very efficiently Potential waste heat sources for heat pumps can be significant Interface issues will need to be resolved between the owners of secondary heat sources and DH network operators
