An investment providing a lifetime of savings Danfoss solutions provide a lifetime of savings Driven by the global need to reduce CO2 emissions, new legislations around the world are demanding air conditioning systems with higher energy performance as well as non-ODP(1) and lower-GWP(2) refrigerants. These legislations affect all unit types and lead to the redesign a large number of HVAC ranges.

Danfoss compressors for air conditioning – a lifetime of savings To meet the needs of an increasingly complex HVAC market, our extensive range of compressors offer functional benefits and savings throughout the lifecycle of the system from development and operating costs to servicing and maintenance.
Savings on development costs Commercial and office buildings, hotels, shopping malls, airports, hospitals, data centers, schools, museums… Every type of building, occupancy, comfort requirements and climate, place different demands on HVAC system design and technological options.
Applying variable speed technology keeps getting easier Variable speed technology offers flexible design possibilities with a wide range of cooling capacities to match different applications and needs. It offers savings in reduced inventory and complexity. In addition, some system components are not always longer needed, including soft starter, phase protectors, etc., and water buffer tanks have been either reduced or eliminated – all of which helps to ensure the competitiveness of development costs.
Savings on running costs with the widest portfolio for superior part-load efficiency 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 energy use.
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 Gas discharge Danfoss IDVs Danfoss Intermediate Discharge Valves (IDVs) mechanically reduce excessive compression of refrigerant under part-load conditions while maintaining the same cooling capacity.
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).
Savings with Danfoss Turbocor® compressors TT 200 TR (700 kW) Air-cooled Chiller Danfoss Turbocor® oil-free centrifugal technology The Turbocor® family of compressors delivers outstanding energy efficiency in full- and part-load operation with energy savings of more than 42% compared to traditional compressors. The outstanding integrated part-load efficiency is the result of optimum energy performance through the entire operating range from 100% to ~20%.
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.
Extended equipment life and minimal scheduled maintenance with oilfree Danfoss Turbocor® compressors Reduced maintenance and mechanical complexity are primarily driven by the elimination of oil from the refrigerant circuit. Friction-free magnetic bearing technology eliminates the cost of oilrelated equipment and management hardware as well as the maintenance costs associated with oil service. This improves long-term heat exchanger performance and delivers outstanding sustainability and long service life.
