13. Key benefits of the Variable Speed fan kits

14. Key benefits Three key benefits for the end user

15. Condensing pressure control • The benefits of the condensing pressure stabilization are: • Stable evaporating temperature • Avoid flash gas • A better evaporator optimization during full year The kit « READY TO INSTALL » optimize the Tecumseh condensing units.

16. Saving energy • for a year round example the « READY TO INSTALL » EC fans kits can save up to 8% of the energy consumption of the Condensing unit. • As an example in a positive application the end user save up to 107 € per year. • Details on the appendix 24 Comparison between electrical consumption of an electronically commutated (EC: blue line) and a standard shaded poles fans (AC: red line) both equipped with variable speed controller. The Tecumseh solution saves the end user money !

17. Decrease the sound impact On the appendix 25 please find an example with a condensing unit. More than a soft start, EC technology offers a significant sound reduction

18. From the wholesalers to the end user

19. Press release of the kits • Chillventa : Official launch • Press release: during October 2012 on major European media.

20. Technical features

21. Give a response to the winter evaporator degradation • When the ambiant temperature decrease the evaporating temperature dropt also. • This lead: • Icing the evaporator • Flash gas • Decrease the global lifetime • Decrease the global COP • Expansion valve not well adapted Insure a smoother running condition

22. C.U. Variable Speed fan kits easy selection Ec Ø 250/300mm fans Diam. 250 or 300mm 1 cable EC Ø350mm fans Diam. 350mm 2 cables AC fans Shaded poles or PSC 1 cable

23. Variables Fan Speed kits description

24. Yearly energy saving simulation Example for a positive application (R404A) at Strasbourg average temperature and a comparison between a 90W AC standard fan and a Tecumseh EC fans. (Calculated with U.K. V.A.T. electricity price, 2010 )

25. Sound power reduction EC motor benefits: CAJN4517ZHR example: -6 dB(A)

26. EC Spare parts references

27. Other AC solution alternatives • Two controllers are requested to insure the variable speed solution • Wiring on the control panel to be added • Two types of wiring are needed: • Control • Power supply Tri phases fans assembly Pressure information coming from liquid line Power supply 3 ~ 400V 50Hz No all-in-one solution available on the market
