1 1 2/9/2014 Energy Savings, Power Reliability, Environmental Stewardship The benefits of on-site cooling, heating and power

2 2 UTC Research Center – Technology Advancement Hamilton Sundstrand Aerospace & Industrial Pratt & Whitney Aircraft Engines, Gas Turbines & Space Propulsion Sikorsky Helicopters On-site & Transportation UTC Fuel Cells Otis Elevators, Escalators & People Moving Systems Carrier Heating, Cooling & Refrigeration Chubb Security & Fire Protection UTC POWER OVERVIEW

3 3 Cooling, Heating & Power Fuel CellsHeat-to-Energy Power & Heat On-site power solutions UTC PRODUCT OVERVIEW

4 4 Waste Heat Solutions for On-Site Generation

5 5 Provides: Up to 200 kW electrical power Benefits: Zero fuel costs Zero emissions Waste heat above 500°F (gaseous) 2 – 4 Year payback 20% IRR or higher PURECYCLE TM 200

6 6 Conventional Industrial Facility 20 MCF/hr Natural Gas Industrial Facility with PureCycle TM Power System 20 MCF/hr Natural Gas REDUCED ELECTRIC NEED

7 7 PRODUCT CONCEPT PureCycle Power System reverses air conditioning cycle CoolingElectricity Air conditioner ElectricityHeat PureCycle Power System NO X Fuel Cost

8 8 Electrical Power Waste Heat Gas > 500°F Power Module Rejected Heat PURECYCLE TM 200 SCHEMATIC Waste heat enters the evaporator and vaporizes a pressurized working fluid. 1 The hot vapor is then expanded through a turbine to drive a generator producing electric power. 2 The condenser cools the expanded vapor, returning it to liquid form. 3 The cooled liquid re-enters the power module, where the pump re- pressurizes it and returns it to the evaporator. 4

11 11 POWER MODULE

12 12 Pressurized Exhaust Evaporator DVR Valve Heat Source 2)Ambient Exhaust (ex: most industrial processes) To Power Module & Condenser 1)Pressurized Exhaust (ex: Recip, Turbine) STANDARD INSTALLATIONS Blower Heat Source Evaporator

13 13 Low O & M costs – estimated at about 0.7 ¢/kW-hr for full maintenance (both scheduled and unscheduled) Uses existing production components from Carrier –Minimizes cost, increases reliability PureCycle system requires no operator –No steam/water in power cycle –Remotely monitored, unattended operation Closed-cycle operation Minimal scheduled maintenance duties –Replace filters –Check oil levels –Replace lube oil –Refrigerant make-up OPERATION & MAINTENANCE

14 14 CARRIER SERVICE NETWORK 80 field offices in the US Continuous Remote Monitoring – 24 x 7 Internet access via web browser Carrier Monitoring Center Alarms, service predictions Dispatch field technicians Detect and correct problems early, to maintain savings and productivity

15 15 Gases: Input Temperature > 500F; Heat input > 8.5 mmbtu/hr APPLICATION GUIDE Q in = m dot x c p x (T in – T out ) Heat Input = mass flow x specific heat x exhaust temp. drop (btu/hr) (lbs/hr) (btu/lb/F) (F) Q in must equal 8,500,000 btu/hr to make 200 kW (lbs/hr) = SCFM x 60 x (use density of air at STP) (lbs/hr) = ACFM x 60 x density (use density of air at actual T, P) C p = 0.26 (conservative, for lean burning natural gas) T out = 300 F
