GCAP
is working with Mayekawa "MYCOM" and getting
a Cascade system brought the US with hands on
training. Ammonia will be on the high temp side
with CO2 as a brine on the the low temp side. This
concept has been used in Japan, China, Europe, and
many other countries successfully the last 10
years. It will reduce the primary charge
(ammonia) and keep it in one central location. It also
has many other benefits. Click

Randy
Williams, Jeremy Williams, and Jacob
Williams traveled to Japan in September 2010, to
tour the factory where they are being built and see
some of them in application. A few cold storage warehouses,
production facilities and even grocery store application. 

Garden City
Ammonia Program (GCAP) located in Kansas U.S., a
private industrial ammonia technical school, decides
to introduce NH3/CO2 cooling
system NewTon3000.
GCAP is the
only private industrial ammonia technical school
providing lectures on refrigerating theory and hands
on training for operating refrigeration systems. It has supplied training to operators
from 412 companies from over 16 countries and produces
experts in refrigeration systems every year. Since CO2
emission reduction and prevention of global warming
are their missions, they actively provide education
for operators who handle refrigeration systems using
natural refrigerants.
In recent
years, regulations for ammonia charge have been
tightening

In terms of the
kinds of refrigerants used in the
refrigeration cycle, restrictions were
introduced in 1996 to terminate the use
of all CFCs (such as R12) with serious
ozone layer destructive properties. The
use of HCFCs (such as R22) and their
ozone layer destructive properties are
to also be gradually phased out by 2020.
Furthermore, since even HFCs (such as
R134a, R407C, R410A and R404A), which do
not contain chlorine and which were
developed and introduced into practical
applications as alternative
refrigerants, have high global warming
potential, it was decided at the Kyoto
Protocol COP3 meetings (3rd Session of
the Conference of the Parties to the
United Nations Framework Convention on
Climate Change), held in 1997, to
designate them as substances whose
release to the atmosphere was to be
controlled. Against this background, in
Europe where environmental awareness is
strong, efforts have been made to review
substances that are not compounds, such
as chlorofluorocarbons, but which exist
in the natural world for use as
refrigerants and, in the years after
COP3, natural refrigerants have come to
be spotlighted not only in Europe but in
Japan and the United States as well. |

"Natural
refrigerants" are substances found
in the natural world, and their most
salient feature as refrigerants is that
they have a much smaller impact on the
global environment compared to
artificially synthesized fluorocarbon
substances.
Some of the natural refrigerants
currently garnering attention include
hydrocarbons, ammonia, CO2,
water and air. However, since
hydrocarbons and ammonia pose problems
in terms of their combustibility and
toxicity, thereby limiting their
applicability, it is believed that the
greatest attention will be paid to CO2
refrigerants in the future.
Although the global warming potential of
CO2 is not zero, the impact
resulting from the disposal of equipment
using CO2 and the release of
CO2 used as a refrigerant
would be equivalent to only 0.0013% of
the amount of CO2 generated
by Japan, if the refrigerant in all the
country's air conditioners were replaced
with CO2.
