1.
The pressure ratio(Pcr) should satisfy the following conditions:
1）900~2000rpm：1.5≤Pcr≤8.0
2）2000~6600rpm：2.0≤Pcr≤8.0
2.
If the suction pressure, pressure ratio out of the used envelop under normal operating
conditions ， the following tips should be considered to make the compressor operating
reliability.
3.
In the transitional stage to the final operating condition, the suction pressure and
pressure ratio should satisfy the following conditions.(lasting time≤5min each time):
a.)
The suction pressure can be lower than 0.168MPa, but should not below 0.137MPa.
b）Pressure ratio value

.
The transitional stage ：the system start-up, defrosting or other operating control(on/off
or transformation of operating conditions)，the stage when pressure or temperature changing
rapidly.
