Ozone Depletion

Global Warming

Montreal Protocol

Kyoto Protocol

CFC ：banned in 1996

Reduction of global warming gas by 6%from 1990 level in the first period of 2008～2012). HFC are the target

HCFC：Limited from 2004
Totally Banned in 2020Freon Recycling Law:

・Price will go up

・Instable gas
・No ODP・Specified as GDP gas by Kyoto Protocol
・Anticipated to be regulated by authority

NH3NH3/CO2CO29

NH3-CO2 system

Safest Approach of NH3 Refrigeration Systems(Indirect Systems)

Direct method

Indirect method

・Potential leak in storage room

・Least potential of leakage in storage room

・Requires large amount of ammonia

・uses very small amount of ammonia

・Simple system

・A bit more complicated system

BkW comparison at partial load

Refrigeration Capacity(kW)NH3-CO2 system gives better performance at all load.
16

By changing the refrigerant from R404A to NH3/CO2,
27% power reduction at full load is possible.
In partial load conditions, the power reduction may beless, still some 20% reduction is achievable.

17

Japan is working toward the natural refrigerant coldchain.
Major shift is taking place through the governmentalencouragements and the efforts of Individuals,industries and the professional and industrial
associations.

18For the use of natural refrigerant, India is in a goodposition.
India can be a leader of the world byA) Encourage and Promote use of Ammonia inrefrigeration application through incentives
B) Guidance for the use of Ammonia refrigeration
system through BIS standard
