Experience of the Russian-Danish Training Center on the use of alternative substitutes for R12
Abstract
Under the training program approved by Danish Environment Protection Agency (DEPA) a Russian-Danish Training Centre for raising the level of refrigeration technicians" skill is established in St.Petersburg at JSC ”SPb CRE”.
As part of the program the students become acquainted with (1) International and Russian legislation on the ozone layer protection; (2) technical essentials of CDS substituents application; (3) practical skills in the technology of the substituents usage in operating refrigeration plants.
Non-ozone-depleting refrigerant R134a and transient refrigeration blend ASTRON 12 (group C10M1) are taken for R12 substituents in the education program.
R134a is applied in refrigeration equipment retrofit procedures and ASTRON 12 is used as a "drop-in” R12 substituent in refrigeration machinery under operation.

Replacement of ozone depleting substances used as refrigerants
Abstract
The development of the refrigeration industry, which is an indispensable link in the modern food production chain (as well as in many other areas of modern human activity), was due to the invention and development in the 30s of safe liquid refrigerants, which were halogenated carbons. At that time, these substances were received with great enthusiasm as a miracle of science, because they are chemically inert, non-flammable (some of them are even used as fire extinguishing agents), low toxicity and effective as refrigerants.
