Restriction Start Conditions
[Operating two units] in common for cooling and heating
¥ When either expansion valve counts 480 pulses and the OH temperature
>
97
℃ ⇒
the compressor speed will decrease at a rate of
100 min
-1
/ 30 second.
[Operating one unit for cooling]
¥ When the expansion valve of the operated unit counts 480 pulses and the OH temperature
>
97
℃ ⇒
the compressor speed will
decrease at a rate of 100 min
-1
/ 30 second.
[Operating one unit for heating]
¥ When the expansion valve of the operated unit counts 480 pulses and the OH temperature
≧
97
℃ ⇒
the expansion valve of stopped
unit will open until 250 pulses are counted at a rate of 20 pulses / 20 second.
¥ When the expansion valve of the operated unit counts 480 pulses and the OH temperature
>
97
℃ ⇒
the compressor speed will
decrease at a rate of 100 min
-1
/ 30 second.
※
¥ The decreasing rotation speed is based on that when reduction processing is started and will hold until decreasing is finished. However,
the reference rotation speed will be replaced only when the target speed is lower than that when reduction processing was started.
¥ Reduction of compressor speed is inhibited when the OH temperature is between 94
℃
and 97
℃
and does not rise from 30 seconds
before.
◇
Restriction Release Condition (in common for all)
¥ Restriction is released when the OH temperature
<
94
℃
and the compressor speed increases at a rate of 50 min
-1
/ 30 second to
restore the target speed.
