Taking the upper limit of compressor command speed range at 60 rps, if the output speed obtained with the fuzzy
calculation exceeds the upper limit, the upper limit value is maintained.
The lower limit of compressor command speed is set to 40 rps and even if the calculated result becomes lower than
that after fuzzy calculation, the speed is kept to 40 rps. However, when the
thermo becomes OFF, the speed is
reduced to 0 prs.
