Parker Jewish HospitalEngine-Generator Based CHP for Hot Water ApplicationsCOMBINED HEAT AND POWER FOR: Nursing Home/Rehab FacilityOverviewParker Jewish Hospital, in New Hyde Park, NYopened in 1850. It currently serves as a nursinghome for long and short term care patients andthose in need of rehabilitation. The hospital iscommitted to reducing energy usage and energycosts in an effort to save money and to reduceecological impact on the environment. Toachieve this goal, Parker installed four 75 kWTecogen cogeneration units.The ApplicationThe CHP system includes four natural gas fueledreciprocating engine-generators having acombined electrical rating of 300 kW. The site’selectric demand is sufficient to keep the systemoperating at or near its rated capacity on acontinuous basis.Annually the system is anticipated to displace2,250,266 kWh and displace 150,362 therms ofgas through heat recovery. Annual fuelconsumption is 283,833 therms. Thermal outputfrom the units will be used to meet various hotwater loads in the facility and to pre-heat boilerfeed water. A dump radiator will reject anyunneeded thermal energy.Quick FactsLocation:New Hyde Park, NY(Consolidated Edison)CHP Equipment:(4) Tecogen CM-75Installation Date:Heat Recovery Application:2012 Domestic Hot Water &Boiler FeedOperating Experience: Type of Fuel:Beginning 5/2012Natural GasGenerating Capacity:300 kW“CHP offers several distinct advantages overmany other electricity and thermal energygenerating technologies with regard toperformance, availability, and cost.”- US Department of Energy Report, 12/08“Combined Heat and Power – Effective Energy Solutions for a Sustainable Future”Web Links and Further Information:Developer/Engineer: www.allsystemscogeneration.com/Equipment Manufacturer: www.tecogen.comDG/CHP Resources: chp.nyserda.org

Parker Jewish Hospital’s CHP PlantCHP System and EquipmentHeat is recovered as hot water from the engine jacket at a supply temperature of 205°F. A heatexchanger separates the engine coolant from the DHW load side equipment. Additionally, exhaust heatexchangers are used at each engine to provide additional heating to boiler jacket water. Boiler water ispulled from the lower boiler jacket, mixed with makeup water, and circulated through the four engineexhaust HX and re-injected at a higher point in the boiler jacket. Excess heat is rejected from the DHWhot water loop to a dump radiator.Domestic HotWater LoopHeat Recovery LoopHot Water PumpsDump RadiatorCogen EngineArraySteam LoopEconomics and Environmental BenefitsBoiler FeedWater PumpsThe CHP System at Parker Jewish Hospital is estimated to reduce carbon emissions significantlyreducing its environmental impact. CHP efficiency is usually twice that of conventional utility power.It is expected that Parker will see a dramatic reduction in energy costs of up to 50% and in their totalcarbon footprint. Monitored data are being collected from the site and are available in an hourlyformat on NYSERDA’s DG/CHP website starting from May 2012.Summary of BenefitsReduces carbon footprintsignificantlyMore than 50% less energy isused to run the systemTecogen CM-75 Engine GeneratorPrepared for NYSERDA by:CDH Energy Corp.Cazenovia, NY 13035315-655-1063www.cdhenergy.comdgchp_data@cdhenergy.com
