Frequency Controlled Semi-hermetic Screw Compressors SP-111-1

Product catalog summary

Specifications:
The document outlines detailed specifications for compressors using R134a refrigerant, recommending polyol-ester oil (BSE170) for optimal performance. It categorizes compressors by type: HSK7471-70VS, HSK8561-90VS, HSK8571-110VS, and HSK8591-140VS, with performance data for 30 Hz, 50 Hz, and 90 Hz frequencies.

Performance Data:
Performance data is provided for various operating frequencies (30 Hz, 50 Hz, and 90 Hz), detailing cooling capacity (in Watts) and power consumption (in kW) across different evaporation and condensation temperatures, essential for assessing efficiency and energy needs.

Procedures and Recommendations:
The document stresses the importance of using an oil heater to maintain oil lubricity during long standstill periods, particularly for outdoor installations, extended shut-off periods, high refrigerant charge, and risk of refrigerant condensation in the separator, to prevent refrigerant dilution and maintain viscosity.

Technical Data:
Technical data includes displacement volume at minimum (20 Hz) and maximum (90 Hz) frequencies, oil separator types for DX systems, maximum working current, and frequency inverter specifications, along with voltage requirements and oil charge specifications.

Accessories and Oil Charge:
It specifies a self-regulating heater at the oil separator, with voltage requirements of 200-230 V and a power rating of 200 W for models OAH 2888 and OAH 7088. The oil charge type is BSE170 for R134a refrigerant.

Key Parameters:
- Refrigerant: R134a
- Oil Type: Polyol-ester oil (BSE170)
- Frequency: 30 Hz, 50 Hz, 90 Hz
- Voltage: 200-230 V
- Power Consumption: Varies by model and frequency
- Cooling Capacity: Varies by model and frequency

Limitations and Best Practices:
Ensure the use of the specified oil type and maintain the oil heater during standstill periods to prevent refrigerant dilution and maintain oil viscosity. Follow the specified voltage and frequency requirements for optimal compressor performance.
