  1. Introducing COOLNOMIX™

  2. Contents • Setting the Scene: Energy Consumption • Introduction to COOLNOMIX™ • Case Studies • Q & A

  3. Energy Consumption (1) • Environmental pressures: • governments are increasingly legislating to reduce energy consumption • governments are exploring “carbon” taxation • consumers and business partners are beginning to discriminate based on environmental factors

  4. Energy Consumption (2) • Business pressures: • global competition continuously puts pressure on costs • Cooling is a significant contributor to energy consumption and costs

  5. Energy Consumption1 (3) • In Hong Kong’s total commercial sector: • air-conditioning accounts for nearly 26% of all electricity consumption • air-conditioning + refrigeration accounts for about 38% of all consumption • for comparison, lighting accounts for 13% of all consumption • In Hong Kong’s office sector: • air-conditioning accounts for 53% of all electricity consumption • lighting accounts for 14% of all consumption Note 1: Hong Kong End-use Data 2011 (EMSD, Sep 2013)

  6. COOLNOMIX™ is a patent pending product range of Agile8 Agile8’s objective is to reduce worldwide running costs of direct refrigerant-based cooling systems1 by 30% Retrofit solution for fixed temperature, commercial environments Note 1: COOLNOMIX™ is for systems where the air is cooled directly by the refrigerant evaporators; not when the refrigerant evaporators are used to cool water which is then used to cool the air

  7. COOLNOMIX™ has been commercially available for more than 12 months and is delivering remarkable savings • an average 40% savings on air-conditioners • an average 30% savings on refrigeration systems

  8. Some of our customers…

  9. Energy savings are achieved by patent pending COOLNOMIX ORS™ • ORS™ optimizes the run-time of the cooling system compressor, responsible for ~95% of energy consumption • COOLNOMIX ORS™ leverages a key cooling plant design objective • designed plant capacity exceeds peak demand to provide a margin of safety • COOLNOMIX ORS™ operates to reduce operational costs whilst: • improving temperature stability • prolonging the life of the compressor

  10. COOLNOMIX™ employs dual temperature sensors, one for the space temperature the other for the cold supply • single sensor cooling systems operate “blind” • COOLNOMIX™’s second sensor provides feedback on compressor’s hydraulic work • Energy savings: • cold supply temperature used as a proxy for deciding when the compressor has completed its work • compressor then switched off until further refrigerant compression is needed

  11. Temperature stability: dual sensors maintain temperatures within +/- 0.25˚C • ORS™ incorporates: • a priority on achieving and maintaining space set temperature • protection against frequent stop/start of the compressor • ORS™ extends compressor life through reduced run-time • ORS™ eliminates icing & dripping, the latter increasingly a focus of legislation

  12. Retrofit Solution

  13. Retrofit Applications (1) • COOLNOMIX™ units can be deployed for savings on: • any direct refrigerant-based air-conditioner or refrigerator, including • split-type air-conditioners • window-type air-conditioners • package type air-conditioners • VRV/VRF/Inverter type air-conditioners • ducted air-conditioning systems • industrial size refrigerators • cooling systems operating between 0oC and 31oC

  14. Retrofit Applications (2) • COOLNOMIX™ retrofit units are suitable for commercial premises deployments • One COOLNOMIX™ unit is required per cooling system thermostat • Retrofitting is about one hour per system • savings begin immediately • zero maintenance requirements • COOLNOMIX™ retrofit deployment is not intrusive to the system: • COOLNOMIX™ only displaces the thermostat function • COOLNOMIX™ does not interfere with the system control functions

  15. Frequently Asked Questions • Doesn’t the increased stop/start of the compressor reduce its life? • protection against frequent stop/start of the compressor – maximum # of stop/start per hour is ~6 • the reduced compressor run-time prolongs its life! • Doesn’t fitting COOLNOMIX™ invalidate the warranty? • only displaces the thermostat function & does not interfere with the control system • in any event, is the warranty worth losing 30%+ savings?

  16. Value-based Pricing • Assume 7.5kwh air-conditioner • 1kWh = US$0.15 • air-conditioner operates 7 days/week, 9 hours/day • air-conditioner is needed 8 months/year • normal duty cycle of compressor is 70% • energy savings are 30% • Annual savings = US$517 • Ten year savings = >US$5,170 • Current pricing policy targets pay-back on investment within the first 12 months; minimum end-user price = US$384

  17. Case Study: Ocean Park • 12th largest theme park by visitor numbers • Trial Oct-Nov 2013; Panda Café • 4 custom-built package AC’s – total 303 kW • >38% savings • Annual savings > US$46k in Café • Production roll-out to 2,000 AC’s

  18. Case Study: CHI Residences • Boutique serviced apartments • Trial June-July 2013 • Daikin split-type AC’s • 41.8% savings • Production roll-out to 7 properties – 1,000 air-conditioners • Annual savings ~US$60k per property

  19. Case Study: ASM Pacific Technology • Provider of fabrication machinery to chip industry • Trial June-July 2013 • Mitsubishi Package AC Unit (30hp/22kW) • 33.85% savings • Production roll-out to all production facilities – 200 air-conditioners • Annual savings ~US$288k

  20. Case Study: Shine and Shine (1) • Fresh fruit-juice manufacturer • Trial November 2012 • Custom-built walk-in refrigerator – 750 sq ft • 40% savings • see graphic on following slide

  21. Case Study: Shine and Shine (2)

  22. Case Study: Shine and Shine (3) • Fresh fruit-juice manufacturer • Trial November 2012 • Custom-built walk-in refrigerator – 750 sq ft • 40% savings • see graphic on following slide • Refrigerator decommissioned & replaced by walk-in refrigerator without heating for de-icing

  23. Case Study: Shine and Shine (4) • Fresh fruit-juice manufacturer • Trial June 2013 • Custom-built walk-in refrigerator – 750 sq ft • 24.5% savings • Production roll-out to three walk-in refrigeration units • Shine and Shine’s entire annual production cooled under COOLNOMIX™

  24. Key Messages • COOLNOMIX™ delivers genuine and significant energy/cost savings on your existing cooling systems • COOLNOMIX™ continues to deliver savings over its life-time – at least 10 years • COOLNOMIX™ improves temperature stability • Pricing policy targets payback on investment within 12 months

  25. Q & A

  26. Competitive Analysis • COOLNOMIX™ is the only third-generation technology in this space of which we are aware • Earlier generations, some of which we had an involvement in, deliver some savings using a single temperature sensor • These technologies suffer from a number of problems, the most significant being that space temperature drifts upwards
