The refrigerant carbon dioxide was on average, the
most well-known natural working fluid. However,
with an average value of 3.1 out of a maximum of 4,
which indicated “very familiar”, there is still room for
improvement. Surprisingly, although hydrocarbon
refrigerants have only recently been approved for use in
small applications in the US, respondents were nearly as
familiar with their characteristics as they were with those
of CO 2
. Ammonia reached similarly high values (3.0 out
of 4.0), whereas water and air, in their use as refrigerants,
showed a clear information deficit, ranging more in the
“mostly unfamiliar” to “somewhat familiar” categories.
Results shown by level of familiarity indicate that
while respondents are either “very familiar” or at least
“somewhat familiar” with the use of CO 2
, hydrocarbons,
and ammonia. The refrigerants air and water would
need more support to reach such awareness levels. A
significant 52% and 46% of respondents said that they
were either “mostly unfamiliar” or “not at all familiar”
with air and water, respectively, as refrigerants. A clear
knowledge gap exists, and it will need to be closed
before a wider market adoption can occur.
