Compressors for Commercial Air Conditioning Savings now and for a lifetime Danfoss compressors reduce costs across the entire product lifespan in the application. Build your business with a 360° perspective and experience the benefits of true savings. Development, operations, servicing: 3 levers for a lifetime of savings

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 very few current systems will pass the minimum efficiency requirements. As well as conforming to strict new standards, next-generation systems need to meet the challenges of complex applications, increased energy efficiency and varied climates, while...

A global overview of CO2 emissions and regulations impacting HVAC markets Numbers in bubbles: CO2 emissions from the consumption of energy in millions of tons in 2012 % of growth of CO2 emissions 2002/2012.

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. Development costs Running costs Service costs The versatility, flexibility and efficiency of Danfoss compressors ensure competitive design costs and short development times Danfoss technologies offer the widest portfolio for superior full and part-load efficiencies to reduce the running 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. Whatever the target application or industry, Danfoss provides OEMs flexible and competitive design solutions for commercial rooftops, chillers, close controls, heat pumps and process chillers with shorter time to market and competitive applied costs. Manifold configurations enable competitive design costs and staged modulation Several...

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 no longer needed, including soft starter, contactors, phase protectors, etc., and water buffer tanks have been either reduced or eliminated – all of which helps to ensure the competitiveness of development costs. Danfoss inverter scrolls VZH 2nd generation of Danfoss inverter scrolls have been...

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 Manifold compressors 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. Energy performance is further enhanced with Danfoss IDV technology. In other terms, the benefits for the running...

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 Danfoss IDVs Danfoss Intermediate Discharge Valves (IDVs) mechanically reduce excessive compression of refrigerant under part-load conditions while maintaining the same cooling capacity. They adapt the effort of the motor to the pressure conditions in the system by opening when condensing pressure and pressure ratio (part-load) fall below the built-in optimization point of the scroll. This reduces the effort of the motor and its...

EERnet SEER Annual En. Input (kWh) Running cost (€) (*) CO2 emission (metric Tons) (**) 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...

Savings with Danfoss Turbocor® compressors TT200 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%. The Danfoss Turbocor® compressor uses an integrated variable frequency drive to reduce compressor speed and maximize energy cost savings as...

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 Danfoss has over 10 years of experience in R410A scroll compressors and billions of compressor operating hours in...
