Page 7: Cut Away Dsf 270-530
How do IDVs work? Figure 3: Intermediate Discharge Valve (IDV) Danfoss Intermediate Discharge Valves (IDVs) are located close to the discharge side of the compressor. They reduce excessive compression of refrigerant under part-load conditions while maintaining the same cooling capacity. The IDVs open when discharge pressure falls below the built-in optimization point. -

Page 15: Mechanical Vibrations
A compressor generates some vibrations that propagate into the surrounding parts and structure. The vibration level of a DSF compressor alone does not exceed 120 µm peak to peak for DSF090 to DSF200, and 154um peak to peak for DSF270 to DSF530.. However, when system structure natural frequencies are close to running frequency, vibrations are amplified due to resonance phenomenon. -

We can consider two means to reduce compressors sound radiations: Acoustic hoods are quick and easy to install and do not increase the overall size of the compressors. Acoustic hoods are available from Danfoss as accessories. Refer to the tables above for sound levels, attenuation and code numbers. -
Page 42: Manage Operating Envelope
If an unacceptable level is identified, a discharge muffler with the appropriate resonant volume and mass can be installed. Mitigation methods Mitigations methods: To ensure minimum vibrations transmission to the structure, strictly follow Danfoss mounting requirements (mounting feet, rails etc..). For further information on mounting requirements, please refer to section Design compressor mounting. - Page 43 No risk of operation beyond the application envelope. No DGT protection required. DSF090 to DSF200 have no integrated discharge temperature protection, an external protection is required. This external protection device can be a thermostat or a temperature sensor. The discharge gas temperature protection must trip the power supply when it reaches the setting point to protect the compressor from overheating.

The significant silver content in these brazing alloy will help the brazing operation, providing an excellent fluidity and a limited heating temperature.
- Page 56 Scroll compressors, DSF090 to DSF530 | Application The use of self-flux alloys (as phosphorous alloys) is not recommended by Danfoss. This type of brazing require a higher working temperature, that may overheat the connectors, damaging the thin layer of copper, resulting in phosphides creation and joint zone embrittlement.
