1 Heat pumps and their economics

2 There has been fluctuations before Johnson Controls2

3 Energy prices are fluctuating at a high level Johnson Controls3

4 Heat pumps technology are not new 4Johnson Controls Brochure from 1982 The key benefits haven't changed, but its now more attractive than ever before…. Extensive experience in industrial heat pumps

5 What is a heat pump? A heat recovery technology such as heat pump can bring more value to your business:  Transform low value heat to high value heat  Generate an extra income to your business by reusing waste heat  Reduce noise level from evaporative condenser/ cooling tower Johnson Controls5 Before After

6 What is it all about? Traditional thinking in refrigeration: You can reuse some of the heat from the refrigeration system Think “out of the box”: Generating new business, then you can use several heat sources like:  Ground water  Water in a harbour  Waste water  Boreholes or land that needs to be drained on a constant basis  Exhaust gasses Johnson Controls6

7 The gas price vs. The price of electricity Johnson Controls7 Italy = 3,9 Sweden = 1,4

8 The ratio electricity price/gas price in praxis Johnson Controls8 For Sweden: For Italy:

9 An example from Croatia Johnson Controls9

10 What is the driving force? Johnson Controls10 CO 2 is becoming part of the bottom line

11 Using the energy on both sides Johnson Controls11 EER= Q cooling /W COP heat = EER+1 COP combi = (Q heat +Q cool )/W

12 As is scenario Johnson Controls12

13 The sustainable solution Johnson Controls13

14 Cooling tower economics Water and bleed off water 1,8 (min) Chemicals 0,4...0,67 €/m 3 Legionella sampling of water 700 € for 3 towers (1.100 € for more than 3) Maintenance contract4% of installation cost Johnson Controls14

15 An example from the industry Johnson Controls15

16 16 HEAT PUMP solutions and offerings Single stage ammonia heat pump based on reciprocating compressor technology Johnson Controls Waste heat from process or condensing heat from existing refrigeration equipment. Single-stage 8-cylinder compressor heat pump +39°C +70°C COP = °C +64°C 963 kW 1149 kW Electrical power 186 kW Hot water for cleaning, or heating purposes

17 17 HEAT PUMP solutions and offerings Single stage ammonia heat pump based on reciprocating compressor technology  Industrial reciprocating compressor designed for R717 heat pump application  Low ammonia charge, approx. 50 kg for the largest unit  Maximum outgoing water temperature: 70 °C  Maximum heating capacity: 1149 kW (39°C source /70°C water out )  Temperature lift limited by design parameters Johnson Controls Heat Source Water out

18 Heat Source °C HEAT PUMP solutions and offerings Single stage ammonia heat pump based on screw compressor technology  Industrial screw compressor designed for R717 heat pump application  Maximum outgoing water temperature: 90 °C  Maximum heating capacity: 1600kW (40°C source /85°C water out )  1000 – 6000RPM variable speed drive as standard Johnson Controls

19 References and how does it look like? Johnson Controls19 Heat pump based on screw compressor, type HeatPAC 157

20 Now what can I use the heat pump for? If you cannot use the heat at site – sell it. Heat can be used for:  Sanitary hot water  Space heating  Process heating  Cleaning  Disinfecting  Drying The cold water can be used for:  Cooling of condenser of refrigeration plant  You can sell refrigerated water and in return you get heat for free  Exhaust air, compressed air and processes can generate heat for the heat pump Johnson Controls20

21 In Summary Johnson Controls21 Alt. Sell the heat

22 In Summary Johnson Controls22

23 HEAT PUMPS MAKE SENSE HEAT PUMPS ARE GOOD FOR BUSINESS HEAT PUMPS IS A SUSTAINABLE TECHNOLOGY HEAT PUMPS ARE NOT NEW TECHNOLOGY Johnson Controls23 So what do we know now?

24 Thank you for your attention
