E360 Webinar to Focus on Efficiency Regulations and Refrigerant Changes in Commercial HVAC

The commercial HVAC industry is facing significant changes to energy efficiency regulations, safety standards and refrigerant changes over the next several years. In our next E360 Webinar, “Are You Ready for the Upcoming Efficiency Regulations and Refrigerant Changes in Commercial HVAC?”, we will look at the convergence of these activities, their timing and what the potential impacts are to commercial HVAC operators. David Hules, Emerson Climate Technologies’ director of commercial marketing, air conditioning business, will present this informative Webinar on August 2 at 2 p.m. EDT. The Webinar will begin by outlining key industry trends and then discuss options available to address imminent regulations.

According to the U.S. Department of Energy (DOE), HVACR comprises 50 percent of all energy consumed in U.S. commercial and residential buildings. On Jan. 1, 2018, the DOE will nationally adopt the IEER portion of the ASHRAE 90.1-2013 standard in A/C packaged and split systems to help mitigate this energy consumption. Currently, this building energy code has been adopted only minimally at a state level.

Meanwhile, the global movement to phase down hydcrofluorocarbon (HFC) refrigerants will soon impact the A/C industry, specifically, proposed actions by the U.S. Environmental Protection Agency to change the status (delist) of common chiller refrigerants such as HFC-I34a, R-410A and R-407A. As a result, the industry is moving toward new alternative refrigerants that have a much lower global warming potential, among these being mildly flammable A2L refrigerants. In response, national and international standards are under revision to evaluate the safety of A2L fluids as manufacturers move to develop A2L-based equipment.

The Webinar will also present incentive opportunities for complying with the Consortium for Energy Efficiency’s unitary specification for A/C and heat pumps that went into effect earlier this year — specifically, the energy efficiency ratios and integrated energy efficiency ratios for part load efficiencies per size category, system type and tier level. To achieve these efficiencies, there are a number of technology options on the table that will be discussed, including: multi-speed blower and condenser fans, modulated compressors, large coil heat exchangers and electronic controls.

The impacts of achieving these higher part load system efficiencies will also be explained:

  • Potentially higher first costs, yet lower operating costs
  • Increased in system footprint from larger heat exchanger surface area
  • Reduction in system refrigeration circuits
  • Increased use of mechanical modulation and variable speed compression technology

Finally, the Webinar will present the timing of these converging regulations and provide an opportunity for attendees to get answers to their specific concerns.

Register to join this informative Webinar taking place August 2 at 2 p.m. EDT, and don’t let the coming changes catch you unprepared.
