COMPRESSOR CRITERIA
1 Strictly observe the specification
The compressor should be used in specifications written in this
“
compressor specification
”
and
not be used in specifications outside it. Moreover, accessories should be specified parts used in
specified way, service must use specified parts too. The main circuit must link up
with fuse or
breaker.
2 Source voltage
Specified inverter is linked up with compressor terminals . Applied voltage of this inverter
should be voltage specified in this “ compressor specification ” . Alternating voltage should
never be applied on terminals (for example：commercial alternating voltage of
1
φ
100V,200V,3
φ
200V).This is because that if applied alternating current the direct
current motor will demagnetize.
3 Operating voltage range
The compressor should be operated in the range of rated voltage 10% , under standard condition
and overload condition of rated frequency (applied voltage to inverter).
It must be satisfied with item 5, 6, 7 and the overload condition should not be continuous.
But the standard condition and overload condition mentioned here refer to condition that specified
in GB/T 7725. (The standard condition refers to the rating cooling condition and the overload
condition refers to the maximum operating condition.)
4 Operating temperatures and pressures
The operating temperatures and pressures of a compressor should be within the range shown in
the table 1.
