CO2 "Carbon Dioxide "
TRAINING STARTS IN FALL
NH3/CO2 Cascade Systems
Garden City Ammonia Program is announcing the third phase of training here at GCAP's hands on technical school with natural refrigerants. The new training will be used to teach NH3/CO2 cascade systems and CO2 Refrigeration.
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.

Randy Williams, Tyler Ramos, 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.
