As I mentioned in one of my earlier communications on this subject, IT
Power India manages a large program in India to train private sector
refrigeration technicians in the techniques of managing Hydro Carbon (and
HFC) refrigerants used in domestic refrigerators. So far approximately 7000
technicians have been trained in the last 3 years, thanks partly to WHO
contributions to our training center. A reformulated program will shortly
be extended to include automotive AC systems also.
The issue of safety as well as long term performance was clearly a
preoccupation several years back. The situation has evolved substantially
over the last 3-5 years and the main barrier encountered in India today
relates to authorization to package and market HC refrigerants in small
containers suited to the service sector, rather than safety issues related
to maintenance. You have correctly pinpointed in your note, the major
advantages of HC for small scale applications. I also fully agree with you
that HC should not be used for walk-in cold/freezer rooms, and its use
should be limited to refrigerator systems of up to 300-liter capacity. One
further additional advantage of HC is that it does not require the
stringent standards of maintenance required by HFC, hence is much easier
for maintenance technicians to handle.
Many thanks for your inputs and look forward to discussing this further.
