Tecumseh Embraces the
Transition to Hydrocarbon Refrigerants
TEPSE SA_ Thessaloniki _ 2011

Project scope
is a New Platform for AE / TP / TW Compressors
Today Tecumseh offers three fractional horsepower compressor platforms for
LBP, MBP and HBP commercial refrigeration applications, they are the AE, TP
and TW.
What AE2 will bring to Europe :
 Best in Class Efficiency
 Back to competitiveness
 Innovation image i.e. Propane R290
Targeted market : Soft-serve ice cream, Ice makers, Commercial freezers,
Bottle coolers , Display cases, Sanitary hot water… Compressors & CU

Why Tecumseh has chosen R290 for
commercial refrigeration?

It is an environmentally friendly refrigerant
 Non Ozone depleting (Zero ODP)
 Very low impact on global warming:
 GWP=3, versus R404A= 3700, R134a=1200
 Non toxic
 Reduced energy consumption: -5% to -10%versus R404A

It improves the reliability of refrigeration systems:
 R290 is a pure refrigerant: not a mixture, no glide…
 Lower discharge temperature/ R404A

It is an economical solution:
 No major modification versus R404A refrigeration systems.
 Natural refrigerant, highly available.

Flammability is manageable for small medium refrigeration
appliances:
 Safety issues can be easily overcome by the use of simple guidelines

R290 versus other low GWP refrigerants
 CO2
 CO2 requires important and costly modifications of refrigeration
system.
 Efficiency improvement is not always demonstrated, especially
on small systems.
 CO2 is not the good candidate for small and medium size
refrigeration. However, it may be acceptable for large systems
• R600a
 R600a is also a good candidate.
 However it’s smaller volumetric capacity, and higher pressure
ratio, limits it to very small refrigeration capacity systems like
domestic refrigerators and freezers.
