In the theoretical world of climatologists carbon dioxide is a warming gas with a supposed logarithmic effect. But in the real world of industrial cooling manufacturers are increasingly preferring to use carbon dioxide as a refrigerant.
Surely if carbon dioxide works as a coolant in industry don’t the same principles apply on our open atmosphere? It sure does according to the 2011 ground-breaking experiments of Professor Nasif Nahle of Monterrey, Mexico. [1.]
But before we dismantle the climatism myth that carbon dioxide has a logarithmic heating impact let’s consider the proven cooling properties of this amazing trace gas. A leading industry expert, Dick Topping Director of Appliance Research (TIAX, LLC) writes: “The use of CO2 as a refrigerant dates back more than a century, but it fell out of favor in the air-conditioning and refrigeration industry with the development of chlorofluorocarbons (CFCs) in the 1930s. Shortly thereafter, hydrochlorofluorocarbons (HCFCs) such as HCFC-22 were developed, and HCFC-22 eventually became the primary refrigerant for stationary air-conditioning systems. However, when concerns about the depletion of the stratospheric ozone layer emerged in the 1970s, national and international agreements were enacted to phase out CFCs and HCFCs.” [2.]
Industry Experts: CO2 is ‘Green Refrigerant’
The irony in Topping’s next section is sublime. The industry expert goes on to tell his readers that the phasing out of CFC’s is “leading many researchers and manufacturers to reconsider “natural” refrigerants such as CO2, hydrocarbons, and ammonia, because these substances have negligible direct global-warming impact and ozone-depletion potential.”
Topping then advises that because CO2 is “not subject to venting restrictions” we should “expect to see systems that accommodate the unique characteristics of CO2 as a ‘green’ refrigerant in the years ahead.” So is CO2 a warming or a cooling gas? Other industry experts agree with Topping. Linde, a world leader in the field, also calls CO2 a “High quality natural refrigerant.” [3.]
While in Japan, Sanyo developed that country’s first commercially-viable CO2 refrigerant in 2009 which they say will “greatly contribute to the prevention of global warming.” Sanyo declare that if freezers and refrigerators were switched to a “CO2 refrigeration system, the CO2 emission reduction effect would be about 50 percent.” [4.]
Even carbon-hating Wikipedia concedes that CO2 is “a natural refrigerant.” While in the nuclear industry the advanced gas-cooled reactor (AGR) and the Magnox reactor, both use carbon dioxide as the coolant. But hold on a cotton-picking minute. It turns out ordinary plain Jane air is also a natural coolant – what ever happened to the UN’s notion that “our atmosphere keeps our planet warmer than it would otherwise be”? [5.]
Wikipedia can’t seem to figure out the glaring contradiction in it’s message when, on the one hand, it declares, “The simplest, and most popular refrigerant is water.” Then almost in the next breath states “the vast majority of the greenhouse effect is due to water vapor in the air.”
