Savings on running costs with the widest portfolio for superior part-load efficiency Low Pressure Ratio, part-load, discharge pressure is low, IDVs open High Pressure Ratio, full load and heating mode, discharge pressure is high, IDVs close Reduce CO2 emissions and energy consumption to get to the energy efficiency standards: Danfoss provides three options to help OEM customers meet the challenge Enhancing part-load efficiency with staged modulation The number of compressors running at any one time can be adapted to building occupancy and demand levels. This improves cooling efficiency and reduces...

Savings on running costs Variable speed technology Continuously matches cooling needs with high efficiency Variable speed technology is the premium solution in commercial air conditioning when it comes to energy savings, optimal comfort, accurate humidity and temperature control and controlled impact on the electrical network. Around 85% of traditional commercial air conditioning installations are oversized to enable them to handle peak load conditions (about 3% of the operating time). Variable speed technology continuously matches building cooling demand under part-load conditions which is the...

Savings on service and maintenance costs HVAC units often operate under harsh conditions that can affect the lifetime and reliability of the unit itself: Frequent on/off cycling, high ambient start-up, defrost mode, low superheat conditions, high ambient operations, oil equalization and oil return at part-load operations can all have severe effects on the entire lifetime and compressor applications. Danfoss scroll DSH: a new level of compressor robustness and system reliability Extended equipment life and minimal scheduled maintenance with oilfree Danfoss Turbocor® compressors Danfoss has over...
