While the space temperature in a refrigerated space may be used to control the refrigeration system, there is a lot more going on that we must also take control of. The thermostat initiates a pump down cycle to control/limit refrigerant migration to protect the compressor and enable defrost to occur more rapidly. Control over the temperature, humidity, velocity and direction of air leaving the unit cooler must be maintained to ensure that product is not dried out or frozen even when stored in temperatures above freezing. How product is placed within the cooler or freezer must be controlled so that sufficient airflow through the space and around the product occurs for quick and efficient heat removal.

Building an energy efficient house that is affordable! Raised on the Monterey Peninsula (California), Larry Weingarten has been self-employed most of his working life. He got his general contractor's license in 1982. Hot water has been an interest in its many forms, so Larry has been a member of the National Association of Corrosion Engineers (NACE) and The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE). In 1992, he and his wife completed the Water Heater Workbook. He has written articles on water heating and energy for various trade journals and has taught about these topics for PG&E, California State Parks, Affordable Comfort and others. Larry finished building an off-grid home in 2006 which was designed to be very efficient, comfortable and inexpensive. It was the 13th home to meet the '1000 Home Challenge', a competition for creating super-efficient homes. With over 50 years of dealing with man-made things and their makers, he has come to believe that self-sufficiency is an important goal to work towards. In episode 557 of the Fraternity Foodie Podcast, we find out where Larry's passion for hot water came from, what he learned by building an off-grid home in 2006 which was designed to be very efficient, comfortable and inexpensive, how enlisting the powers of openness, perspective, and a quiet mind can go far in helping you fix any problem, how mentors have impacted his life, what is a good investment when fixing run-down homes, what is the difference between responding and reacting, what cats do for him, and what is the value of life.

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 Q&A podcast episode, Bryan answers a listener-submitted question about circuit board troubleshooting: is there a quick way to learn how to check circuit boards, and if so, where are those resources? A circuit board is a bunch of components put together on a printed circuit board (PCB). There isn't a lot of helpful universal information about circuit boards available, as they vary quite a bit by model and manufacturer. However, many of the basic components will be the same across circuit boards: microprocessors, diodes, relays, capacitors, and transformers. If you understand what these are on their own, that will help you understand what they do in circuit boards.  You mostly need to know the inputs, outputs, and sequence of operation of a circuit board to diagnose it. The sequence of operation tells you when certain things are supposed to happen, such as in an integrated furnace control (IFC); the flame rectification process is a classic example. If the flame can be proven, the operation continues; if it can't be proven, then that will cause a lockout (possibly due to improper grounding or poor placement and NOT necessarily because of the board). A lot of issues with the board can be diagnosed if you understand the inputs and outputs (e.g., 24v signals) or observe it with your senses, such as bloated capacitors or ant nests. Becoming a master of the obvious and checking the manufacturer's literature are the top two things you can do to diagnose circuit boards.   HVAC Control Systems by Ronnie Auvil Electricity for Refrigeration, Heating, and Air Conditioning by Russell Smith Have a question that you want us to answer on the podcast?

In this episode of the HVAC School Podcast, Trevor Matthews and Bryan dive deep into the transformative potential of artificial intelligence (AI) in the refrigeration and HVAC industries. They explore how AI is not a new concept in their field, discussing how manufacturers like Copeland, Sporlan, and Danfoss have long incorporated AI-driven tools and repositories of information into their applications. The conversation goes beyond simple technological novelty, positioning AI as a powerful learning and troubleshooting assistant for technicians. The discussion highlights AI's role as a supportive tool rather than a job replacement. Trevor emphasizes that AI cannot physically perform trade-specific tasks like climbing ladders or brazing pipes, but it can provide invaluable guidance, explain complex procedures, and help technicians quickly access specialized knowledge. Particularly beneficial for less experienced technicians working late-night shifts or challenging service calls, AI can serve as an instant reference point, helping to jog memory and provide step-by-step troubleshooting guidance. Bryan and Trevor both stress the importance of approaching AI with curiosity and critical thinking. They advise against treating AI-generated information as absolute truth, instead recommending users ask follow-up questions, verify information, and use AI as a conversational learning tool. Trevor is actively developing a specialized AI platform for refrigeration training, working to train the system with industry-specific knowledge and real-world experience to create a more accurate and helpful resource for technicians. Key Topics Covered: AI's current applications in refrigeration and HVAC industries How AI can support technician learning and troubleshooting Strategies for effectively using AI tools The importance of maintaining technical knowledge while using AI Trevor's ongoing development of a specialized refrigeration AI training platform Practical examples of AI use in technical and non-technical scenarios Addressing concerns about AI potentially "dumbing down" the industry   For those interested in participating in Trevor's AI beta test, email info@refrigerationmentor.com with the subject line "Looking to be included in the beta test for the refrigeration training AI."

Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves by Nicola TwilleyPrime Future Newsletter by Janette BarnardThe Great Beef Bonanza and the Fall of the Cattle Kingdom"Our ancestors learned to control fire before modern humans even evolved. But our ability to command cold at will dates back a little more than 150 years. Mechanical cooling refrigeration produced by human artifice as opposed to the natural chill offered by weather dependent snow and ice wasn't achieved until the mid 1700s and wasn't commercialized until the late 1800s, and it wasn't domesticated until the 1920s."That is a quote from the book that we're gonna be talking about here today, Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves by Nicola Twilley. I'm very excited to dive into this book. There's so much here on the history of refrigeration and we take for granted how much refrigeration has changed our food system and our world in a number of profound ways.But I'm also excited to not be tackling this massive project by myself. Coming back for another episode is my good friend, animal agtech venture capitalist, and creator of the Prime Future newsletter, Janette Barnard. Also from Twilley's book: "It's impossible to make sense of our global food system until you understand the mysterious logic of the all-but-invisible network of thermal control that underpins it. We overcame not just rot, but seasonality and geography as well."Listen as Janette and Tim unpack their takeaways from this incredible book about the history of refrigeration.
