A complete guide to understanding the types of Danfoss compressors

Danfoss is the world leader in inverter-based compressors for commercial HVAC and provides uncompromising efficiency with its compressor capacity ranging from 3 to 350 tons.  Danfoss compressors enable cost-saving throughout the product lifespan through wide-ranging HVACR applications in industrial and residential buildings, data centers, telecom facilities, IT system cooling, etc. The blog gives a detailed insight into the advantages delivered by Danfoss’ technologically advanced compressor solutions.

Danfoss Turbocor compressors

Danfoss Turbocor oil-free compressors have redefined the industrial HVAC systems with state-of-the-art technology that has set new benchmarks for the lowest operating costs over a prolonged lifetime in chiller applications. Danfoss Turbocor centrifugal compressors are the world’s leading oil-free compressors, featuring innovative & proven technologies like magnetic bearings, advanced digital controls, and variable-speed centrifugal compression.

Danfoss Turbocor TTS and TGS compressor models have a compact size and low weight that allows OEMs and other contractors to target cost-efficiency in the installation and a smaller footprint compared with conventional compressors. These compressors have extraordinary low-noise operating features with no vibration. This disregards the need for noise protection systems. The Danfoss Turbocor oil-free compressors offer excellent energy efficiency in full and part-load operation, saving up to 42% more than traditional compressors. Every Danfoss Turbocor compressor has an inbuilt soft start module that significantly decreases the in-rush current during the start-up, benefits the line power systems, and reduces thermal stress.

Danfoss Scroll compressors

Danfoss scroll compressors provide the highest efficiency and reliability even in low-temperature ranges. The 3rd generation of Danfoss inverter-based scroll compressors have been enhanced for part-load functions to deliver the highest efficiency across a wide range of applications. The prequalified scroll compressors and drive packages curtail the development time and increase the reliability in varied operations. The Danfoss inverter scroll VZH with IDVs has a wide-ranging capacity spanning 4 to 26TR in one circuit, also 52TR when employed in hybrid tandems at full speed functions.

Danfoss VZH inverter scroll compressor responds to environmental and energy-related challenges using Interior Permanent Magnet (IPM) motor, which provides higher efficiency. These scroll compressors have been designed for varying pressure ratios to achieve the highest efficiency across a wide range of applications.

The scroll compressors sport a precise cooling feature that regulates temperature and humidity for the best comfort and process, data availability, and product quality. These features enhance the energy savings and provide a shorter payback period of 3 years for most end-users. These compressors' have a 30% less footprint than their alternative, reducing logistics costs and making the overall system compact.

Danfoss Reciprocating compressors

Danfoss Maneurop - VTZ inverter-based reciprocating compressors are used for cooling and commercial applications. These reciprocating compressors avert you from using oversized and short cycling systems as they automatically adapt to the applied current load in commercial systems like chillers, air conditioning, and rooftops. Using these variable speed compressors, you can target precise and stable temperature regulation up to ±0.3°C that improves process & equipment reliability.

Reciprocating compressors are fitted with VTZ drives that vary the rotation speed within a frequency range of 30 - 90 RPS based on the cooling requirements. Hence the compressors are compact in dimensions concerning the cooling functions and deliver a high COP across the whole operating range. The variable-speed compressor models are designed several sizes smaller to match the nominal system load; hence the efficiency is increased for every capacity load. Furthermore, the energy consumption of the VTZ compressor is lower when the compressor operates at a reduced speed. Also, the product competitiveness is augmented with the high efficiency (at part load) and with improved SEER.

In conclusion

Danfoss AC compressor innovations support OEMs to compete in the challenging technology space and improve the part-load efficiency, maintaining the full-load performance while making a transition to low-GWP alternatives. In the whole process, the development costs are maintained at competitive levels to provide lifetime savings. Using Danfoss advanced compressors drive solutions you can build or redesign your business with a 360° technology perspective and top-notch industry experience which will drive efficiency as well as cost savings in your HVAC applications.
