Application Guidelines

Inverter compressors

Single compressors

Compressor size

Frequency converter variants

Inverter technology oﬀers more ﬂexibility in compressor selection than ﬁxed-speed compressors. Selection of the right inverter compressor size can be made by diﬀerent methods:

1. Maximum cooling capacity: Select a compressor size which achieves the peak load system cooling capacity demand at its maximum speed.

2. Nominal cooling capacity: Select a compressor size which achieves the nominal system cooling capacity at a rotational speed of 3600 - 4500 rpm (60-75 rps).

Diﬀerent frequency converter variants are available according to: Frequency converter for VZH028-035-044 200V&400V: CDS803

1. Mains supply voltage:

- 200-240V/3ph/50-60Hz

- 380-480V/3ph/50-60Hz

2. IP class (CDS803 drives are available in IP20 or IP21 (requiring additional kit) housings)

3. Best Seasonal Eﬃciency Ratio: Select a compressor size which achieves the minimum system cooling demand at its minimum speed. Ensure that the compressor is able to cover the peak load system cooling capacity. This selection makes the compressor run for a maximum time at part load where the system eﬃciency is highest.

Performance tables at three speeds can be found in the following pages. Detailed performances can be found in datasheets and in selection programs.

3. RFI (Radio Frequency Interference) class H4

4. Printed Circuit Board (PCB) coated Frequency converter for VZH028-035-044 575V: CDS303

1. Mains supply voltage: 525-600V/3ph/50-60Hz

2. IP class: IP20

3. RFI class HX: No ﬁlter

4. PCB not coated

Compressor and frequency converter combinations

VLT Compressor Drives literatures

When the compressor size and mains voltage have been deﬁned in the above selection criteria, the code number tables from the “Ordering information and packaging” section provides the appropriate frequency converter sizes and up to eight corresponding code numbers for each compressor model.

VLT Compressor Drives User’s Manual (FRCC.ES.017.A1.02) introduces diﬀerent VLT

Note this compressor is equipped with a four-pole electrical motor so the applied frequency from the inverter will be 30 Hz for 15 rps (900 rpm) up to 200 Hz for 100 rps (6000 rpm).

Oil return management

Bearings lubrication

Oil return management function only works under auto mode: After running at low rpm (less than 40 rps) for 120 minutes, the internal lubrication algorithm in the drive will accelerate the compressor speed to 60 rps or above for 60 seconds to ensure suﬃcient lubrication of compressor moving parts.

Warning:

This function is enabled by parameter 28-10 as default setting. Please notice when hands on mode is selected, oil return management will

A speciﬁc oil pump ensures optimal bearing lubrication at all compressor speeds. The speciﬁc oil pump provides suﬃcient bearing lubrication

not work even if parameter 28-10 (oil return management) is set to on. If compressors run below 40 rps for more than 120 minutes, oil return fault alarm (A208) will report on LCP and stop the compressor. Please select hands on mode carefully and only select hands on mode if the OEM has implemented oil return management in the system controller and qualiﬁed oil management. Under such conditions, the compressor could run below 40 rps continually and meanwhile disable drive oil return management 28-10.

at low speeds as well as to avoid excessive Oil Circulation Ratio (OCR) at high speeds.

Sight glass / Oil level sensor

VZH compressors OSG versions come equipped with a threaded oil sight glass with 1"1/8 – 18 UNEF connection. It can be used for a visual check of oil amount and condition.

Schrader

The oil ﬁll connection and gauge port is a 1/4" male ﬂare connector incorporating a schrader valve.

Suction & discharge connections

VZH compressors are all delivered with suction and discharge brazed connections only. They are copper-plated steel connections.

Rotolock adaptors are available, refer to the “Accessories” section.
