5 Overview CHP & Trigeneration Energy efficient products/solutions Our Partners
6 The CHP Process 100% Prime Energy Losses from Transmission and Conversion Usable Energy Efficiency Ratio 35% -65% -10% + 90% up to Local Cogeneration Plant
7 Gas Engine CHP Sizes from 100 kwe 4MWe Heat from engine cooling water ( 90 C) + heat from hot exhaust gases ( 400 C) harnessed Heat/Power Ratio 1.1/1 Uses for heat: up to 90 C for space heating or hot water demand Steam for Industrial Process Exhaust gas CO 2 generation Absorption Chilling Low temperature demand, i.e. for underfloor heating, swimming pool etc.
8 Natural Gas Fired CHP Unit Fully containerised, factory built and tested
9 Biomass CHP Biomass CHP is the use of a biomass fuel to simultaneously generate both electricity and useful heat in a renewable process
10 Biomass CHP CES Energy offers biomass CHP solutions for large industrial i sites Biomass fuel can be woodchip from forestry or energy crops (miscanthus, willow etc) System electrical outputs from 500 kw e 5 MW e Full heat recovery giving hot water/steam Heat:Power ratio > 3:1 CES Energy has established relationships with industry leading suppliers worldwide Biomass CHP solutions offer zero carbon alternative to conventional fuels (gas/oil etc)
11 What is Tri-generation? Tri-generation is the simultaneous generation of the 3 primary energy requirements for a building from a single fuel input. Electricity Heat Cooling This plant consists of these primary components: CHP plant Absorption chiller Distribution system Control system Heat dissipation equipment
12 Absorption Chiller Dual fired with diesel burner back-up Jacket Water In/Out Cooling Water Outlet Engine Exhaust Outlet Engine Exhaust Inlet Chilled Water Outlet Fuel Exhaust Chilled Water Inlet GAS Inlet (Auxiliary firing)
13 Why Tri-generation? Tri-Generation offers a use for waste heat on a site when there is no heat demand Below is a load profile of a typical commercial building showing high summer cooling demand Load (kw) ELECTRICAL CHILLING HEATING 0 jan feb mar apr may Month jun jul aug sep oct nov dec

21 ENERGY EFFICIENT COOLING OF DATA CENTERS
22 Environment aspects Approx data centers are located in Germany. The current consumption is 8,67 Terawatts per year, discharging 5,6 million tons CO 2. In 2010 the discharge will be 8,3 million tons. The worldwide CO 2-discharge of the data centers is approx. 62 million tons. (source: Sustainable Partner GmbH) Prognosis: The global l power demand d of all data centers worldwide raises up about 40 % until (source: Jonathan Koomey/IDC) Is IT the new climate killer?
23 Key figures Key figures for evaluation of the data center efficiency Power Usage Effectiveness PUE = TFP (Total Facility Power) IEP (IT Equipment Power) DCE = 1 PUE Site Infrastructure Energy Efficiency Ratio Total Facility Power IT-PEW SI-EER = IT Equipment Power (IT-Production per embedded Watt) Data Center Energy Efficiency and Production Index (DC-EEP) DC-EEP = SI-EER x IT-PEW

43 Free Cooling Chillers Indirect free cooling Twin or triple compressor technique Design with maximum free cooling capacity Small floor space due to double heat exchangers
44 Free Cooling Chillers To maximise the efficiency of these chillers they are best operated at flow and return Temperatures of 8 C and 14 C From Met Eireann Data the Temperature in Dublin is at or below 6 C C for 24% of the year (Free Cooling) The etemperature peatuein Dublin is sato or below beo 12 C C for 67% of the year (Part Cooling)

46 Dry Coolers The same effect of the Free Cooling Chillers can be achieved on existing installations by installing a Dry cooler in parallel with the chiller The dry coolers work on the same principal of cooling the return fluid temperature to the flow temperature or as close to it as possible A bypass valve allows the fluid to flow directly into the chiller when the ambient temperature will not aid cooling The plant will however take up space which may not be available
47 Dry Coolers Free or part cooling when ambient air below 12 C 14 C 8 C
