TECHNOLOGY DESCRIPTION

DC INVERTER TECHNOLOGY Inverters are used to vary the speed of motors and in this way can be used to control the capacity

of a compressor. For refrigeration users they can be an effective method of accurately matching

compressor capacity to load requirement. A way of reducing compressor output is needed in

almost every application. Without the means to run efficiently at low capacity, compressor

cycling by switching on/off is most commonly used. This method introduces large fluctuations

and high power consumption due to heavily loaded heat exchangers. Multiple compressor

solutions overcome this problem to some extent and stepping by means of cylinder unloading is

used with piston compressors.

Effect of the Inverter on Performance and Power Input

The capacity can be calculated as being in direct proportion to the speed. A compressor is

designed to have optimum pumping efficiency at its nominal speed, usually 1450 rpm. When


[13]

operating at speeds other than the nominal the efficiency will change because of the behavior of

the valve reeds and the change in pressure drop through the valve plate. However, as these tend

to balance out, the change in volumetric efficiency is small.

Power Measurement and Cable Sizing

The inverter can cause distortion of the sinusoidal current waveform, and between the inverter

and the motor there is a stepped current approximating to a sine wave. High quality inverters will

introduce minimum distortion and power losses. Power can be measured using the two

wattmeter method on the input to the inverter. Currents can exceed the amounts calculated from this power. Cables, fuses and contactors will

need to be sized for the true RMS current flowing through them. General rules for this are: Cable from motor to inverter - size for 10% more current than

standard.

Cable from inverter to mains - size for 20% more current than

standard.

Start Contactor Positioning

The inverter should not be allowed to operate with the output from the inverter to the motor

open circuit. There should be a contactor each side of the inverter, i.e. between the inverter and

the mains and between the inverter and the compressor motor. They should be interlocked to

break the mains side first. When switching on, the motor side contactor should be made first. When using an inverter bypass, care should be taken to ensure there can be no voltage feedback

to the inverter. Therefore when the bypass contactor is closed and the bypass is in operation, the

contactors on either side of the inverter must be open.

Starting and Ramp Up

An inverter is capable of delivering a soft start, but at the same time care must be taken to

ensure that stalling does not occur. The inverter must be able to deliver sufficient power at the

lower frequencies to ensure that the compressor accelerates to nominal speed in approximately

3 seconds or less. Only general guidance can be given here, because the exact torque

requirements will depend on system pressures at the time of start up. Longer ramp up times

could result in inadequate lubrication. It may be necessary to set the inverter to deliver a slightly

increased. Voltage (compared to the normal V/f rule in Section 4.5) at the low frequency

applicable during ramp up, but this should not result in deviation from the V/f rule during normal

operation.

Electrical Screening and Voltage Rise

Wiring of the electrical enclosure and the installation must be carefully conducted in accordance

with EMC recommendations. High quality, high reliable pressure sensors must be used and it is

necessary to follow EMC measures to ensure that the inverter does not disturb the signals from

pressure transducers. Suction and high pressure sensors signals must be noise-free to the

controller input. The inverter itself should be fitted with suitable EMC filters. Because the

waveform generated by the inverter is built up from pulses, there is a danger that the rate of

voltage rise on an individual pulse can be too fast. Generally this is measured in kV per

microsecond, and limits at the motor terminals which should be adhered to during the first

microsecond.


[14]

Vibration

A compressor running at fixed speed imposes vibrations on its associated framework at a set

group of frequencies. The framework can of course be designed such that its natural frequencies

differ from the imposed frequencies. A compressor driven at variable speed will impose different

frequencies at each speed, so the framework design to eliminate vibration throughout the speed

range is more complex. The framework structure should be stiff enough such that its resonant

frequencies are above the maximum frequency, i.e. 60 or 65 Hz. Designing with natural

frequencies below the minimum speed 20 or 25 Hz, could lead to vibration problems during start

up. Spring mounts should not be used as they have a natural frequency below 65 Hz.

The operation of internally compounded compressors at variable speed may require the

selection of a different liquid injection interstage cooling expansion valve.
