Major Function
1
Inverter compressor(INV)
According to the actual need, the inverter compressor
can adjust its revolution among 30rps~90rps.
2
Standard compressor(STD1/STD2)
When the inverter compressor fails to meet the needs of the
system, the fixed-frequency compressor will start together.
3
High pressure switch(for INV)
When the discharge pressure of the inverter compressor
exceeds the upper limit of the high pressure switch,
a feedback signal will be sent out to stop the unit
immediately so as to protect the compressor.
4
High pressure switch(for STD1/ STD2)
When the discharge pressure of the fixed-frequency
compressor exceeds the upper limit of the high pressure
switch, a feedback signal will be sent out to stop the
unit immediately so as to protect the compressor.
5
Check valve(for INV)
It is used to prevent the high-pressure reverse gas going into the
inverter compressor at the moment that the compressor stops
so as to avoid abnormal startup next time and other problems.
