In this episode we have my good friend Nelson Sierra join us on CO2 Mondays. Nelson has developed a tool for Troubleshooting any refrigeration system with artificial intelligence (AI). It involves utilizing advanced algorithms and data analytics to diagnose and resolve system issues. He also share with us how he developed the AI tool and how it will help you as a technician troubleshoot better and faster. For end users it will reduce downtime and help you be more proactive in your service and replacement of equipment.
Here's a general overview of how this device can be used for troubleshooting:
Real-time Data Collection: This device will use AI-enabled sensors and monitoring devices and collect real-time data from the compressor in the refrigeration system, such as temperature sensors, pressure transducers, current and volt meters. This data is continuously fed into the AI system.
Anomaly Detection: AI algorithms analyze the collected data to establish normal operating patterns and establish baseline performance parameters for the refrigeration system. Deviations from these baselines are flagged as anomalies, indicating potential system issues or malfunctions.
Fault Diagnosis: When an anomaly is detected, AI algorithms analyze the data further to identify the root cause of the issue. By comparing the current data patterns with historical data and known fault profiles, the AI system can suggest probable causes for the anomaly.
Predictive Maintenance: the AI algorithms can also predict and anticipate future system faults based on historical data and pattern recognition. By identifying early warning signs, the AI system can schedule proactive maintenance or repairs to prevent equipment failure or system breakdowns.
Troubleshooting Recommendations: Once the AI system has diagnosed the issue, it can provide troubleshooting recommendations to address the problem. These recommendations can range from simple adjustments to complex repairs, guiding technicians on the necessary steps to rectify the problem efficiently.
As Nelson mention it's important to note that AI-assisted troubleshooting is not meant to replace human expertise but rather to augment it. Technicians still play a crucial role in interpreting AI-generated recommendations, performing repairs, and ensuring the proper functioning of the refrigeration system.
By leveraging AI for troubleshooting, organizations can benefit from faster and more accurate fault detection, reduced downtime, proactive maintenance scheduling, and improved overall system performance.
Please give Nelson a follow and thank him for this contribution to the refrigeration industry:

I had the opprotunity to have Jim VanderGiessen CEO of Pro Refrigeration join us for a amazing conversation on Pros journey into the CO2 world. They built the 1st CO2 transcritical chiller in North America. How they did it was by getting outside their comfort zone, not listening to the naysayer and taking action towards a vision of natural refrigerants in Chillers. Over the years they have built strong relatinships with customers and clients who were willing to work with them and it is all paying off. They road was steep and they are still coninuting to climb but they are pushing through and making a mark on the CO2 industry. I know they are just getting started. Enjoy.

Getting into the learner's mindset is super important.
It doesn't matter what you're doing whether it's for a technical course,
or just a knowledge base course
It's about getting in and understanding where you're at that point and where you want to be.
I see many people getting into courses, just to get into studies, or to learn a little bit more, but don't put the time and effort into the course.
And that's why I really want technicians, Refrigeration Professionals to understand if you're going into a course
-you want to put the effort in,
-you want to put the time in,
Because it's only going to benefit you the more effort you put in, the more you'll learn.
Today, we're going to learn more about investing in yourself and growing in the Refrigeration industry.

You might be thinking the lights are flashing and they must be okay.
It's always flashing green must mean good.
But it doesn't always mean good.
Flashing lights are not always good.
Usually, solid lights are good. And solid red lights are not very good.
Today, we're going to talk about electronics.
We'll dive into a lot of different aspects and there are so many areas you can take in compressor electronics because that's one of the things that I believe a lot of technicians just walked by.

I did a lot of construction and I've done thousands of feet of piping and I burned a lot of pipe during those days.
It's been 15 years but the thing that I remember is that I've looked at the piping schedule, I grabbed the pipe that I needed, and then I went and started burning it in and doing this constantly adding insulation and stuff.
Today, there are a lot of technicians in construction, who just do all the piping, with some expert pipers in there.
In this episode, as you continue to develop yourself to understand those pipes, we will dive into the following discussions:
-The importance of knowing pipe sizes
-What is the purpose of sloping them and putting hangers on
-Importance of knowing the correct line sizes
-Understand fundamentals of pipes

In our previous episodes, we talked a lot about different topics like compressors and some high-level compressor issues.
We've also talked about piping getting into some refrigerant retrofits and co2.
We also got into personal development and professional development.
So today, we'll talk about some of the refrigeration tools that I use.
Softwares really helped me out in troubleshooting a problem and helping somebody else out.
It's really important to know where to find the information you're looking for.
Because sometimes it can be really hard.
Like when you go to the manufacturer websites and there's so much stuff that doesn't matter which they have so many products and so much information and brochures and technical document
Sometimes it's hard to weave your way through that.
So I highly suggest that you become a good researcher to find the right information, the right documents, and cross-reference data.
In this episode, we'll go through some of that, and some of the software that I use.

We spent the last two episodes talking about co2 as a refrigerant and we had some good conversations.
And now is Part 3 of the episode on (R-744) CO2 as a Refrigerant.
And I really like having CO2 conversations with people who are new to it, as well as people who are experienced in it.
Today I want to share things on co2 that we didn't really dive into and a lot of this is just a high-level overview that I'm going through.
Nowadays, it's easy to gather CO2 information and you'll find more manufacturers have manuals, from components to equipment manufacturers which makes it easier to start learning the process of CO2 knowledge.
