We cover essential concepts such as the refrigeration cycle, sensible and latent heat, superheat, subcooling, and critical system checkpoints.  It doesn't matter what level you're at in refrigeration, understanding the fundamentals is the most important thing for building confidence and being able to troubleshoot more effectively. This episode was recorded as part of a live presentation at the  2022 HVACR Training Symposium. In this episode, we discuss: -Importance of Repetition -Key terms and definitions -The Refrigeration Cycle -System checkpoints -Heat concepts -Superheat -Manufacturer specifications -Dew point and subcooling -Glide and temperature difference -Four main components of refrigeration systems -Sequence of operations in refrigeration systems -Refrigerant dynamics and system adjustments -Metering devices and liquid line diagnostics -Evaporator function and heat absorption -Compressor issues and floodback Helpful Links & Resources: Episode 295. A Compressor Story: The Key to Faster Troubleshooting Danfoss Coolselector®2  

This week Foo has leaves in his gutters and a pond that shreds fish. Battling the critters. Country dogs are different than suburban dogs. Foo deals with new time reporting. Gym has a coolant cap that destroyed itself and Melly's Subaru goes back into the shop. Foo goes to a protest with his daughter and Gym is proud. We go long on time to talk a little politics and voice our frustration. Plus more!

This podcast episode is Part 1 of a Kalos class on rack refrigeration given by Matthew Taylor. This first segment focuses on the basic refrigerant circuit and oil management of a parallel rack system, common in market refrigeration. Parallel racks follow the same general process as any other compression refrigeration system. However, they contain multiple compressors on a single rack. These systems have multiple suction lines that tie into one single suction header that feeds into multiple compressors. The suction side of the piping is usually a long distance with varying elevations; risers are vertical stretches of piping that carry oil and refrigerant up and pose a challenge for oil return. The compressor takes low-pressure vapor on the suction side and turns it into high-pressure vapor on the discharge side. From there, the condenser rejects heat from the refrigerant, which brings the superheated vapor down to saturation temperature and further rejects heat to make the refrigerant fully liquid (subcooled). Metering devices drop the pressure of the refrigerant, and the cases contain evaporators that absorb heat and boil off refrigerant, which travels to the compressors via the suction lines. Parallel racks come in multiple varieties, but the ones in this podcast are of the direct expansion (DX) variety. Saturation remains a critical principle in these systems: superheat, subcooling, and the pressure-temperature relationship all drive system operation.  Matthew also covers: Different types of rack refrigeration systems Customized variations between racks  Looking up case information and reading legends Oil return and controlling velocity Mechanical subcooling Full load amps (FLA) and locked rotor amps (LRA) Temperature glide: dew point, bubble point, and midpoint EPR installation Evaporator efficiency and superheat Compressor types Compression ratio and liquid or vapor injection Oil management components and controls   Have a question that you want us to answer on the podcast?

On a recent call, after some basic troubleshooting. I found that air was bypassing the evaporator coil. I explain how I came to that conclusion on this episode.

  Vidcast:  https://youtu.be/kEjjai5xFkg   The CPSC and the DCT, formerly Goodman, company have extended their recall of molded plastic evaporator drain pans installed in condensing and non-condensing gas furnaces with an up-flow coil configuration. This extension also recalls DCT pains installed in competitor-branded furnaces, that is not Goodman, DCT, or Amana models.    These pans may overheat, deform, and melt creating fire and burn hazards.  About 298,300 of these pans were sold in the US an about 44,000 were sold in Canada.  If you have one of these pans or think that you may have one, contact DCT at 1-888-520-0579 to determine if your pan is included in the recall.  If your pan is recalled, you can register for a free repair by a qualified technician.   https://www.cpsc.gov/Recalls/2022/Daikin-Comfort-Technologies-Manufacturing-formerly-Goodman-Manufacturing-Company-L-P-Expands-Recall-of-Evaporator-Coil-Drain-Pans-to-Include-Those-Installed-with-Non-Condensing-Gas-Furnaces-Due-to-Fire-Hazard   #evaporatordrainpan #melt #fire #dct #Goodman #amana #recall  

Nathan Orr joins Bryan to talk about some logical fallacies, namely the false cause and strawman. They explain how those fallacies show up in the trade. It's difficult to present arguments without using fallacies, but people tend to rely on fallacies to uphold extreme religious or ideological viewpoints or conspiracy theories. Fallacies are also often easier to communicate than nuanced science and data. “False cause” relates to the phrase “correlation does not equal causation.” It can be tempting to link coincidences and say that one thing causes the other, but that could very well not be true. For example, more compressors fail during lightning storms. It's reasonable to assume that lightning causes the failures, but lightning is not simply striking all of the compressors; other power outages and other conditions that happen during storms are more likely plausible causes. Confirmation bias also makes it easy to cling to a false cause. People are likely to disregard data that doesn't align with what they already believe. A strawman misrepresents (or deliberately misstates) another argument to make it easier to attack. People often apply the strawman fallacy to conversations about forming ice in a system during vacuum and duct sizing. Strawman arguments happen more often in business matters, especially if people impugn the intentions of the other party. In many cases, being open to new information will prevent you from falling prey to logical fallacies. Nathan and Bryan also discuss: Flat-earthers Inverter board failures at night Evaporator coil corrosion Simultaneous capacitor and fan motor failures Logical fallacies in chance and gambling The pitfalls of anecdotal evidence and small samples Appeal to emotion Defining “better” Mounting TXV bulbs Heuristics and mental shortcuts   If you have an iPhone, subscribe to the podcast HERE, and if you have an Android phone, subscribe HERE.

Rajan Rajendran and Jennifer Butsch from Emerson join the podcast to discuss the Helix and some refrigerant changes that are coming. Jennifer is the Director of Regulatory Affairs, and Rajan is the Global Vice President for Environmental Sustainability and former director of the Emerson Helix. Lately, there have been more environmental efforts to reduce greenhouse gas emissions, and plenty of large corporations have “net zero” initiatives. Sustainability requires a holistic, systemic approach in our industry; the Helix Innovation Center conducts the research needed for us to handle these sustainability initiatives as effectively and safely as possible. However, the sustainability initiatives frustrate a lot of technicians. There will likely be multiple refrigerant transitions as our industry progresses. Education and knowledge provided by manufacturers and HVAC organizations will be the key to smooth transitions. Many of the replacement refrigerants, including R-32 and R-454B, are A2Ls. These mildly flammable refrigerants have different handling, transportation, and charging procedures than what we're used to. However, we are unlikely to see changes in oils; POE and PVE oil will likely remain dominant in the market. Eventually, we may see more GWP changes. We would also be prudent to focus on preventing and rectifying equipment leaks. Proper maintenance will help us navigate current and possible future changes. Rajan, Jennifer, and Bryan also discuss: The AIM Act and HFC reduction in 2024 GWP-limit petitions in HVAC vs. refrigeration Refrigerants that manufacturers are embracing Refrigerant testing processes Natural refrigerants The weight of refrigerants vs. the weight of air Evaporator coil manufacturing and leakage Built-in leak detection Refrigerant pricing   To learn more about these coming refrigerant changes, check out the AHRI Safe Refrigerant Transition Task Force's resources HERE or Emerson's E360 Platform HERE.
