![]() Subjects covered in the whitepaper include: The whitepaper also covers the impact of regulations, including national and international regulation, GWP limits, and taxes on high-GWP refrigerants, and provides an overview of the most promising alternative refrigerants currently available on the market. Selecting new alternatives implies investments, costs, and educational burdens, but we believe that if these selections are made correctly, and with an innovative approach, they can open doors to new opportunities. However, a balance of these factors can't be found in just one refrigerant for all applications. Selecting suitable refrigerants is a decision that will impact users for years to come, and experts suggest that safety, affordability, and environmental friendliness are the most important factors to consider when building a system. The whitepaper discusses the history of refrigerants, predicts the continued dominance of vapor-compression systems, and anticipates a dramatic increase in refrigerant consumption due to the growing demand for green energy and emerging economies. Exploring trends and drivers in refrigerant selection It contains a summarized look at Danfoss’ experience and knowledge, describing the background, trends, and drivers that frame the scenarios for present and future refrigerant selection. This whitepaper is examining the trends and drivers in selecting refrigerants for heating, ventilation, air conditioning, and refrigeration (HVAC/R) systems. This will result in safer skies, with practically zero margin for flight error.New and evolving regulations on refrigerants can make it a challenge to stay up to date on current trends, with new regulations impacting everything from component selection to designing future systems. ADS-B is a major change in surveillance philosophy – instead of using ground based radar to interrogate aircraft and determine their positions each aircraft will use GPS to find its own position and then automatically report it. ADS-B replaces or supplements traditional radar based surveillance of aircraft. We have been working on next generation synthetic display systems capable of displaying RNP and Automatic Dependent Surveillance Broadcast (ADS-B) symbology. RNP approaches with RNP values allow aircraft to follow precise 3 dimensional curved flight paths through congested airspace, around noise sensitive areas, or through difficult terrains. RNP is a type of performance-based navigation that allows an aircraft to fly a specific path between two 3D-defined points in space. RNP (Required Navigational Performance) procedures, part of the NextGen program mandated by the FAA (Federal Aviation Administration, USA) are fast being embraced across USA and Europe and will soon become the global standard. This is being done by shifting navigation guidance from ground based radar systems to satellite dependent GPS systems. The challenge is to optimize air-travel, increasing traffic in the lanes – by leveraging technology. ![]() Increased air-traffic and density are raising safety & navigational concerns, not only in India but also globally. The economic boom, increased tourism and need for connectivity have led to increased demand for air-travel and connectivity for Tier-2 & Tier 1 towns. The privatization and open-sky policy have led to an influx of niche-players in the skies, who offer no-frills air travel.
