As policies and regulations change, a transition is being made toward low global warming refrigerants and new codes. Here we will discuss ASHRAE 34 and 15, as well as the adoption of new codes and standards and how they can vary from state to state.
Previously we have looked at federal minimum energy efficiency levels and the metrics used today to rate air conditioning systems (such as SEER, integrated energy efficiency ratio, or full load EER). Now we are shifting focus and looking at system efficiency and where it is headed in the future.
This article is going to take a look at efficiency and what that looks like in the landscape of regulations. The focus here will be on energy efficiency regulations and what impacts they are expected to make in the next three years, both from the residential standpoint and also commercial.
In part 2 of this series, this next episode continues the discussion between host, Lindsay Headings and HVACR industry experts Tersh Blissett, Michael Mayberry, Eddie McFarlane, Jerry Rollins, Bryan Orr, Jessica Bannister, and Bill Spohn. These guests toured The Helix Innovation Center in Dayton, Ohio, and the new Emerson labs in Sidney, Ohio. The group discussed highlights of the tour like the Residential Connected home located inside The Helix and brainstormed ways to promote the skilled trades.
With the HVAC industry undergoing changes and becoming more innovative, once-commonplace HFC (hydrofluorocarbon) refrigerants such as R-410A are beginning to phase out. Low-GWP (global warming potential) refrigerants, are in the process of replacing HFC refrigerants. Most of these new refrigerants are classified by ASHRAE as A2L, which means that they are classified as mildly flammable but show promise for energy efficiency and positive environmental impact.
In this episode, Lindsay Headings sits down with HVACR industry experts Tersh Blissett, Michael Mayberry, Eddie McFarlane, Jerry Rollins, Bryan Orr, and Bill Spohn at The Helix Innovation Center in Dayton, Ohio. Jessica Banister also joins us remotely. Our conversation begins with personal back-stories from the experts, including their passion for HVACR, and how that led them to start their social channels.
HVACR service technicians find themselves at the forefront of the refrigerant transition in AC and commercial refrigeration. As hydrofluorocarbon (HFC) refrigerants with high-global warming potential (GWP) are being phased down, mildly flammable A2L refrigerants have been identified as potential lower-GWP alternatives. But information about A2L servicing requirements is largely unknown in the U.S., which raises many questions within the technician community. If you’re an HVACR technician, the chances of soon encountering A2Ls is very likely. It’s important to gain a better understanding of A2Ls to maximize safety and assist your customers with installation and service calls.
In this episode, HVAC School podcast host Bryan Orr is joined by Ryan Gorman, CEO of Coldwell Banker, to give a fresh perspective on a trending topic: College vs. Skilled Trades. A subject that is top of mind for many,
As a contractor, it is important that you are aware of the different federal minimum efficiency levels and compliance requirements across regions. Understanding the new standards and metrics (SEER2, EER2, HSPF2) will help both you and your clients feel confident moving forward with these changes.
While many homes still use the standard single-stage air conditioner, two-stage and variable speed systems are proving to offer better energy output, efficiency, and dehumidification. Learning more about their differences and benefits can help you guide customers toward making the best choice for their home.
