Modern HVAC Systems' Reliance on Refrigerant In 2020, nearly 90% of homes used air conditioning systems in the United States. Heating, ventilation and air conditioning (HVAC) systems are used by both homeowners and businesses alike, with their usage only expected to rise as climate change increases global temperatures. Refrigerant, a chemical compound that is capable of transitioning from liquid to gas and back again, has been an important part of indoor cooling systems since modern AC systems were invented in 1902. Its ability to cool as it vaporizes and heat up as it condenses facilitates heating and cooling. As part of both air conditioner and heat pump systems, refrigerant either helps transfer heat and humidity out of one's home for conditioning or draws heat from outdoor air and brings it inside for heating. Refrigeration technology has historically relied upon gases like chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) to promote cooling in appliances, due to their effectiveness at transferring heat within a refrigeration system. While effective, these gases are hazardous for the environment. HFCs have a global warming potential (GWP) that can be hundreds to thousands of times greater than that of carbon dioxide. Gaseous CFCs have a high ozone depletion potential (ODP), meaning there is less protection from the sun's rays and greater exposure to UVB radiation, negatively impacting human and ecological health. Instead of relying upon harmful CFCs and HFCs in refrigeration technology, UC Berkeley researchers are on the cusp of developing a new alternative known as “ionocaloric” refrigeration, which utilizes salt water to provide cooling. How does Ionocaloric Cooling work?Created in 1987, the Montreal Protocol regulates the production and consumption of nearly 100 human made chemicals classified as ozone depleting substances (ODS). The Montreal Protocol mandated the eventual phase-out of CFCs and HCFCs, instead turning to HFCs as a replacement. Although HFCs do not deplete ozone, they were later found to have a significant GWP, prompting a recent amendment to reduce HFC usage by 80% in the next thirty years. As HFCs are phased out, ionocaloric cooling has been proposed as an alternative for refrigerant. Ionocaloric cooling relies on the principle that liquids release energy, or heat, when solidified, and solids absorb energy when liquified. In an ionocaloric refrigerant system, a mixture of a liquid and salt is frozen and melted. When a current is added, ions flow and change the material from solid to liquid, which allows them to absorb heat from their surroundings. Similarly, when ions are removed, the material crystallizes into a solid, releasing heat. The mixture is easier to manage as it is never in a gas state and is unable to enter the atmosphere. Additionally, certain solvents like ethylene carbonate, which have been used to test the technology, can be carbon-negative due to their ability to be produced from CO2 supplied by carbon capture. This means that ionocaloric cooling can prevent current emissions with high GWP and ODP, while also removing emitted gases from the atmosphere. Promise of Ionocaloric CoolingIonocaloric cooling has the potential to modify current HVAC systems, which rely upon high GWP gases that act as refrigerants. By using solid and liquid components as opposed to HFCs to function, ionocaloric refrigeration prohibits these harmful gases from ever entering the atmosphere. In addition to its cooling purposes, this technology can also be used for heating. Ionocaloric technology has the potential to compete with or even exceed the efficiency of gaseous refrigerant. Currently, ionocaloric cooling technology is still being developed. If proven successful, this innovative technology could transform the current landscape of HVAC systems. Hurdles to OvercomeAs of now, ionocaloric cooling is not fully developed. Although the material cost for the salt water is cheap, it is unclear the cost of every component needed on a larger scale. The research currently being conducted for ionocaloric cooling experimentation is heavily subsidized. As it is still under R&D, this technology's viability on a larger-market scale will be continually determined. To facilitate a transition away from gas refrigerants, ionocaloric cooling will likely need government incentives, such as consumer rebates, to make the technology competitive with conventional units.Dr. Lilley's Insights into Ionocaloric CoolingIn addition to being environmentally harmful, gas refrigerants have proven to be costly and difficult to dispose of. Dr. Lilley believes that ionocaloric cooling can thus be an advantageous solution in a variety of ways. The end of life management (or disposal) of output components from ionocaloric cooling will be much easier as it relies upon liquid inputs. Additionally, Lilley notes that there is no way to completely seal refrigerants from the atmosphere, so a liquid refrigerant eliminates that problem altogether. As the technology becomes more advanced, Dr. Lilley believes that initial cost concerns will fade with state subsidies and market adoption.About our guestDr. Drew Lilley is the CEO and co-founder of Caliion Technologies. He holds a PhD from UC Berkeley in Mechanical Engineering, where his research is focused on alternatives to current refrigerants. His main research focus is on the R&D process of solid-to-liquid ionocaloric cooling. ResourcesAC Direct, Ionocaloric Cooling is Revolutionizing Heating and Cooling TechnologiesBerkeley Engineering, Keep it CoolBerkeley Lab, Berkeley Lab Scientists Develop a Cool New Method of RefrigerationDr. Drew Lilley, Calion TechnologiesIndustrial Refrigeration Pros, The Evolution of RefrigerantsThe American Society of Mechanical Engineers, New Refrigeration Method Relies on Ionocaloric CoolingFurther ReadingCarrier, AC Refrigerant BasicsClimate & Clean Air Coalition, HFCsEIA, Nearly 90% of U.S. households used air conditioning in 2020EPA, Basic Ozone Layer ScienceUNEP, Montreal Protocol Timeline and HistoryUNEP, About the Montreal ProtocolFor a transcript, please visit https://climatebreak.org/out-with-classic-refrigerants-and-in-with-ionocaloric-refrigeration-with-dr-drew-lilley/.

In this short episode, Bryan clears up the confusion behind pumping vs. compression. Pumping is usually associated with liquid. Liquid, like vapor, is a fluid, but it's a lot denser and is essentially incompressible because the molecules are close together. Liquid volume varies based on temperature and density, but we can't squish the molecules together. That's why compressors with very little axial and radial compliance fail when flooded; they can't compress the liquid. A circulator pump in a hydronic system is an example of a pump that pushes liquid along, but the pressure difference across the pump is minimal compared to that of a compressor; the same is true of liquid vs. vapor CO2.  However, vapor molecules are far apart and can be squished together to take up a smaller volume. That's why vapor can go through compressors, which take a fluid of one volume and apply pressure to shrink it to a smaller volume, raising the temperature in the process. Pneumatics, as opposed to hydraulics, utilize compression to move vapor around in a circuit. Recovery machines need to be able to compress vapor refrigerant and pump liquid into the recovery tank. Compressors and pumps can either be positive displacement or non-positive displacement systems. A positive displacement system creates a trap and forces a fixed amount of fluid through a system, like a scroll compressor or a circulator pump. Refrigerant volumes may vary because vapor density varies with temperature and pressure (the volume flow is the same, but the mass flow varies). A condensing fan motor, on the other hand, is dynamic and varies the volume of air it moves in response to pressure, as the mechanism relies on velocity and kinetic energy to move air.   Have a question that you want us to answer on the podcast?

The bad news: The refrigerants we use in air conditioners, fridges, and vehicles absorb hundreds to thousands of times more heat than carbon dioxide does. The good news: We're in the middle of a global effort to replace them with lower impact alternatives.  Will we replace them fast enough to hit climate targets? And in the meantime, can we prevent them from leaking into the atmosphere? In this episode, Shayle talks to Ian McGavisk, senior advisor at RMI for carbon-free buildings. An industry veteran, he recently co-authored a report on recovering residential AC refrigerants in the U.S., which have the carbon equivalent of 1.7 million cars. (Ian also works in business development at Transaera. Energy Impact Partners, where Shayle works, invests in Transaera.). Shayle and Ian cover topics like: The sources of emissions in the refrigerant lifecycle  The economics of recovering and reclaiming refrigerants Alternatives with low global warming potential and their tradeoffs, such as efficiency, flammability and concerns about forever chemicals Recommended resources RMI: Refrigerant Reclamation Project Drawdown: Refrigerant Management Project Drawdown: Alternative Refrigerants EPA: Transitioning to Low-GWP Alternatives in Commercial Refrigeration UN Environmental Programme: Montreal Protocol On Substances That Deplete The Ozone Layer, Report Of The Technology And Economic Assessment Panel, May 2024  Catalyst is brought to you by EnergyHub.

In this short podcast episode, Bryan talks about the CPS Molecular Transformator and what it does. The Molecular Transformator is a version of a tube-in-shell heat exchanger, which is a method of exchanging heat from one fluid medium to another fluid medium. Tubes containing a fluid pass through a shell containing water or glycol, and there is a heat exchange between that secondary fluid and the fluid being circulated in the tubes. In a Molecular Transformator, the fluid being circulated is recovered refrigerant, and the secondary fluid is water (in a bucket), which absorbs heat from the refrigerant and cools it down to make sure that the refrigerant enters the recovery tank as a liquid. Refrigerant recovery machines have condensers inside of them, but they are quite small and don't hold a lot of refrigerant by design; many recovery machines use microchannel coils. A lot of the time, the refrigerant leaving a recovery machine is a liquid-vapor mix and too high-temperature; a lot of people run a hose over the tank or put it in a bucket of ice. The "Molecular Transformator" tries to settle the vapor molecules down into a liquid; it transforms the vapor molecules using the same mechanism of a shell-in-tube heat exchanger. The main issue is that there will be leftover refrigerant in the Molecular Transformator after recovery. However, you can mitigate this problem with ball valves and proper purging. Do so responsibly to avoid venting refrigerant.   Have a question that you want us to answer on the podcast?

As environmental concerns continue to shape regulations, the HVAC industry is undergoing a significant shift away from R-410A refrigerant. The so called “GWP” (global warming potential) is what the EPA uses as an indicator of the “negative impact” of a gas on “climate change.” Todd Russo of REEIS Air Conditioning discusses what the transition means for new and current units plus the potential costs associated with them. The takeaway is be informed!  Avoid potential shady tactics about this transition.

There is one constant in life: change. We will continue seeking a more environmentally friendly, easy-to-handle refrigerant until the day we figure out how to remove heat without the use of refrigerant. That is a given. So what if the next best refrigerant is determined to be milk? How well would it function? What would the pressures be? What oil would it use, if any? Sometimes, we overthink the world we live in and should focus on the basics: what is the evaporator design temperature and the condensing design temperature? These two items are the driving forces of a system, not the pressures. The pressures are a result of the pressure/temperature relationships created by the refrigerants. Tune in to see what we would do if milk becomes our next generation of refrigerants.

This episode focuses on understanding and effectively utilizing various refrigeration system charts and measurements for troubleshooting and diagnostics. Joey Henderson, an HVAC veteran and trainer, shares his wealth of knowledge and experience on this topic. Joey starts by discussing the challenges he faced early in his career when trying to make sense of the confusing charts with arrows indicating high, low, high head, low head, etc. He emphasizes the importance of knowing the "supposed to be" values before attempting any measurements or referencing charts. Without this baseline understanding, the measurements become meaningless. He then delves into specific measurements like subcooling, superheat, evaporator temperature/suction saturation, condenser split, and compressor amperage. For each measurement, Joey explains the ideal range, how to interpret deviations, and how different factors like humidity, airflow, and refrigerant type can affect these values. He also highlights the differences in approaches for fixed metering devices versus TXV/EEV systems. Topics covered in the podcast: Understanding refrigeration system charts and their limitations Importance of knowing "supposed to be" values for meaningful diagnostics Measuring and interpreting subcooling Measuring and interpreting superheat Determining evaporator temperature/suction saturation Calculating and understanding condenser split Evaluating compressor amperage Differences in charging fixed metering devices vs. TXV/EEV systems Impact of humidity, airflow, and refrigerant type on measurements Using psychrometers and measuring wet bulb temperatures accurately Calculating and interpreting Delta T (wet bulb/dry bulb split) Resources like the Efficient Comfort website and Dick Wirz's RefTech app   Check out some of the resources discussed at https://efficientcomfort.net/.

Standard 310 is a technical workflow created by ACCA, ResNet, and ANSI for grading the installation of HVAC systems, typically in new home construction. It plays a crucial role in obtaining Energy Star certification, which can qualify homeowners for tax credits under the Inflation Reduction Act. The five steps of Standard 310 are design review, duct leakage test, total system airflow, blower fan watt draw, and refrigerant charge verification. In this podcast episode, host Bryan Orr is joined by guests Chris Hughes and Eric Kaiser to discuss Standard 310 and its implications for HVAC contractors. The standard aims to ensure that HVAC systems are installed correctly and operate as designed. The process involves a third-party HERS rater conducting various tests and measurements, which contractors need to be prepared for. Proper duct sealing, airflow settings, and refrigerant charging are critical for passing the assessments. One of the challenging aspects highlighted is the refrigerant charge verification step. The standard requires either non-invasive testing (which has temperature limitations) or weigh-in verification with geotagged photos. Chris Hughes suggests manufacturers could develop more consistent commissioning protocols to streamline this process. Topics covered in the podcast: Overview of Standard 310 and its five steps Importance for Energy Star certification and tax credits Role of HERS raters and HVAC contractors Duct leakage testing and proper sealing Airflow measurement methods Blower fan watt draw challenges Refrigerant charge verification options Need for consistent commissioning protocols Coordination and documentation required Future improvements to the standard   Have a question that you want us to answer on the podcast?

Don Gillis and Dr. Chuck Allgood from Chemours join the show to discuss their new easy as "1,2,3" branding around the A2L refrigerants R454A, R454B, and R454C. They explain that A2Ls are not actually flammable like hydrocarbons; they are just mildly combustible with much lower burning velocity and energy than propane or butane. The key is that A2L refrigerants can only be used in equipment specifically designed and tested for them. They outline several equipment changes, like the inclusion of sensors that detect leaks and mitigate risks by shutting down systems. Service ports will be red to denote flammability. Refrigerant cylinders will move away from colors and instead use red bands/markings to signal A2L, along with left-handed threads and updated pressure relief valves. Best practices like nitrogen purging, confined space protocols, and leak repairs will become outright requirements. Tools like recovery machines and leak detectors will need A2L ratings, but most from the past 2 years likely already have them. In closing, the guests emphasize that A2Ls contain no propane or hydrocarbons and cannot be retrofitted into existing A1 equipment. Contractors should get trained, adopt the solutions coming, and not fear progress. But they should spread the word that A2Ls are not simply being dropped into old equipment. Topics Covered: Differences between A2Ls and flammable refrigerants Required safety features in A2L equipment Changes to refrigerant cylinders Updating tools and practices for A2Ls Retrofitting existing systems with A2Ls (not allowed) Spreading proper understanding about A2Ls   Learn more about the 5th Annual HVACR Training Symposium at https://hvacrschool.com/Symposium24.
