Page 6: Abbreviation Description
able to be managed by MBC, MBC will send the alarm signal to the controller to decide whether making emergent stop or not. Therefore, there is no additional anti-vibration required under MBC control function. The vibration level of the compressor body is lower than 1.0 mm/s (overall) when it is dispatched from HANBELL.

Page 27: Chapter 3 Suction Structure
Chapter 3 Suction Structure 3.1 Inlet Guide Vanes: The cooling capacity of the RTM compressor is mainly adjusted by changing the RPM (using a VFD), but this is limited in its range. Therefore, the RTM compressor is also equipped with an inlet guide vane (IGV) angle adjustment mechanism to increase the cooling capacity, as shown in Figure 3.1.
Page 28: Control Of Inlet Guide Vanes
3.1.1 Control of inlet guide vanes: Angles of inlet guide vanes are automatically controlled through a vane actuator with a lever arm, and IGV opening ranges from 20% (minimum load) to 100% (full load). Opening of the vane actuator in percentage (%) has a linear relation to the control signal. However, cooling capacity does not relate the angle changes of guide vanes.

Page 38: Power Consumption Efficiency Of Rtm With Vfd
Note: Hanbell RTM series has dedicated control logic, which includes cooling capacity modulation and protection control logic. If customer has any concern of development of chiller control program, please contact Hanbell. 3.3.2 Power Consumption Efficiency of RTM with VFD RTM series is designed as direct-driven mechanism with variable frequency. This consumption efficiency design is widely applied to different turbine product and can be explained by similarity principle.
Page 39: Operation Range
3.4 Operation Range 3.4.1 IGV Capacity Control with VFD When the centrifugal compressor is at part load, the angle of guide vane becomes smaller and refrigerant volume entering compressor also reduces; when the volume flow decreases to a certain extent, surge and stall may occur. When the compressor surges, discharge pressure drops suddenly lower than the pressure in condenser so high-pressured gas flows reversely to the compressor;...
Page 40: Equation Of Surge Line
3.4.2 Equation of Surge Line Equation of Surge Line is consisted of IGV aperture, pressure ratio and frequency. The equation should be monitored strictly during the capacity modulation of compressor to prevent the frequency is operated out of the limit of the equation. Parameter Description IGV aperture, the input value is from 20 to 100.
Page 41: Hot Gas Bypass (Hgbp)
Table 3.6 Safety margin line of each model Note1: The calculation result of minimum frequency operation reaches surging line, therefore, the frequency of the control logic should be considered to add 2 to 3 Hz based on the calculation value for safety factor. 3.5 Hot Gas Bypass (HGBP) Hot gas bypass is to bypass gas refrigerant or liquid refrigerant from condenser into evaporator through a proportional valve.
Page 42: Chapter 4 Motor
Chapter 4 Motor 4.1 Motor cooling There are two parts of magnetic centrifugal compressor need to be cooled, one is motor stator and another is motor rotor and magnetic bearing.

Note 2: Valve 14 in the above diagram is the intermediate pressure shut-off valve, and it is optional. It is only necessary to choose it for units with dual compressors or more. The intermediate pressure shut-off valve is used to prevent compressor reversal due to pressure differences when the compressor is stopped and waiting to restart.
Page 48: Motor Connection
Note 4: During the startup acceleration process, there may be significant fluctuations of Ke value, which may easily trigger alarms and shutdowns then resulting in startup failures. Therefore, it is recommended to temporarily disable Ke value protection during the startup acceleration process and resume Ke value monitoring after the startup is completed.
