AIR CYCLE TECHNOLOGY
A FUTURE PROOF SOLUTION FOR ULTRA-LOW TEMPERATURES
MIRAI INTEX is an engineering company, since 2015, that is dedicated to the protection of
the environment through the implementation of innovative technologies.
We specialize in designing and manufacturing of turbo compression equipment, based on
which we produce the most energy efficient and cheapest to operate ultra-low
temperature refrigeration solutions.
WHO WE ARE

3. AIR CYCLE TECHNOLOGY
A FUTURE PROOF SOLUTION FOR ULTRA-LOW TEMPERATURES
AIR CYCLE - BACKGROUND
Ø First machine invented in 1851 by John Gorrie for Ice production
Ø Further developed by Joseph Coleman with Henry and John Bell in 1870’s
Ø Later used on board of ships for food refrigeration
Ø Nowadays adopted for the use in aircraft/railway (ICE3) air conditioning and gas
liquefaction

REFRIGERANT COMPARISON AIR vs F-Gas
AIR main Benefits:
Ø Abundancy of air
Ø Constant 0 € price „Forever“
Ø Enviromentally friendly
Ø 0 GWP and 0 ODP
Ø Low pressure operation
Ø non-toxic, non-flammable
Air Standard HFC´s
GWP 0 Wide range
Toxicity None Present
Flammability None Present/Partly
Corrosiveness None None

7. AIR CYCLE TECHNOLOGY
A FUTURE PROOF SOLUTION FOR ULTRA-LOW TEMPERATURES
CYCLE COMPARISON AIR vs F-Gas
Ø Mirai Cold machines underwent independent technical assessment by Prof.
Dr.-Ing. habil. Michael Kauffeld
Ø Influence of the isentropic efficiency of the compressor and expander were
investigated
Ø More than 0.7 Is.Eff was achieved
Ø 30% higher COP to vapour system (-100°C)
Ø 10 times lower service cost
Ø No F-gas and Safety regulations
