  1. Tecumseh Variable Speed kits for condenser fans Decrease the sound level, maintain condensing pressure. Less than 3 years pay back Vaulx-Milieu, Septembre 2012

  2. Agenda • Tecumseh product offer • Tecumseh product offer • Tecumseh fans description • Variable speed fans availability • The variable speed kits • AC solution • EC 250/300mm solution • EC solution • Key benefits of the Variable Speed fan kits • Products benefits • Condensing pressure control • Saving energy • Improve sound perception • From the wholesalers to the end user • Press release of the Kits • Technical features

  3. Tecumseh product offer • «  READY TO INSTALL » for new installation and adaptable for the retrofit systems • A specific solution for all fan technologies offer by Tecumseh. • An all-in-one solution. • A pre-set kit: 16 Bars for R-404A, an 10 Bars for R-134a.

  4. Tecumseh fans description AC: alternative current EC: Electronically commutated Tecumseh introduces variable speed on all its fan motors

  5. Variable Speed fan availability • The “variable speed” stickers on the fan indicate the opportunity to install a Tecumseh variable speed kit. • A specific logo sticker will be applied: • When the condensing unit is able to handle the variable speed kits • one of the fans assembly spare parts Specific logos and stickers :  Easy identification for wholesalers and installers

  6. AC solution description • The fan speed controller adjusts the fan speed • Only one operation for the wiring • An easy plug on the fan speed controller • No impact on the existing power supply line AC single phase fan Existing power supply Pressure information coming from liquid line A complete and proven solution.

  7. AC kit content • « READY TO INSTALL » AC kit content: • Two preset fan speed controllers for commercial application : R-404A or R-134a • Specific brass tees with screw connection and Schrader valve • Specific cable for fan speed controller • Installation instruction and a quick start manuals

  8. EC Ø 250/300mm solution ESM+ plug • The fan speed controller adjusts the fan speed • Remove the power supply cable by the specific ESM+ plug • An easy plug on the fan speed controller • The condensing pressure is directly connected to the fan by the module. Power supply 230V 50Hz Pressure information coming from liquid line A quick and innovative solution

  9. EC Ø 250/300mm kit content • « READY TO INSTALL » EC Ø 250/300 mm kit content: • Two preset fan speed controllers for commercial application: R-404A or R-134a • Specific brass tees with screw connection and Schrader valve. • Specific cable with ESM+ module • Installation instruction and a quick start manuals for ESM+ module and controller

  10. EC Ø350mm solution • No power supply modification • An easy plug on the fan speed controller • The condensing pressure is directly connected to the fan by the module. • The fan speed controller adjusts the fan speed Power supply 230V 50Hz Pressure information coming from liquid line • Simplest solution on the market

  11. EC Ø 250/300mm kit content • The « READY TO INSTALL » EC kit content: • Two preset fan speed controllers for commercial application: R-404A or R-134a • Specific brass tees with screw connection and Schrader valve. • Installation instruction and quick start manuals

  12. Easy quick reference

  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

  28. Thank you for your attention
