*** Save time. No big picture / executive summary at the beginning. Start at 1:22:00 (one hour 22). You get to miss the ozone gwp lecture and start with the benefits of CO2. The main course still is an additional hour away. The slides are nearly useless because they re difficult to read. The key portion of transcritical, all co2 system technology is rushed to a fault at the end.

i fell asleep watching a build a shed video and woke up to this. Maybe the KZbin algorithm and our AI overlords think we have the brain capacity to watch this because we watch Breaking Bad and geek out elsewhere like electrical engineering or something. Kind of flattered actually.

The audio is distorted because the pre-amp in the audio system is being overdriven. The volume is too high on some device in the audio production chain.

the biggest problem with selling dry ice is the storage of the product. the temperature of dry ice is close to -100 degrees, so a normal freezer isn't cold enough. this means you're loosing a lot of product if its not sold right away.

Is there something about CO2 that makes it more of an asphyxiation hazard than any other class A (low toxicity) refrigerant? The CFC, HCFC, HFC, and HC refrigerants we are used to working with will all displace oxygen and are all denser than air, so how is CO2 worse?
@randymoreno9345
@randymoreno9345 10 ай бұрын
The leak rate (due to its higher pressure) and the expansion ratio of liquid to vapor, decreases the time it takes to displace the oxygen in the room.

There are times where i go to a service call at an absolute dump of an apartment complex, the management doesnt care, the tenants dont care, and they dont want to pay for the job to be done correctly, i find it very had to do a good job in those situations.

Does anyone else purge and pressure test with co2 instead of nitrogen? A bottle of co2 lasts like 10 times longer because its liquid, co2 is cheaper, and co2 is still inert at those pressures.

I worked on an r-290 system for the first time a couple years ago. Three ounces is difficult to weigh in. CO2 will prove to be the most dangerous to technicians it think. 1600 psi is no joke.

#8. No limit on the amount of income that is subject to FICA withholding. If your taxable income is a million dollars you pay social security tax on a million dollars. Yes there will be tax cheating but even with that it will still solve the insolvency problem and I very short order.

And don't get me wrong here, UV protection from ozone is also very important, and we should do everything possible to make sure this layer does not get damaged any further. I love the idea of CO2 as a refrigerant, I love the idea of CO2 capture to use it as a drilling and extraction aid for gas and oil. And please do not mention dino anything when speaking of petroleum products......the dinosaur story is just that.......a story. We should be preparing for the super flare/cme event that is going to cripple us as our magneric field continues to weaken at faster rates than anticipated. All these electrically powered systems are going to be obliterated unless we start to innovate and produce better protection systems for grids worldwide. S. Obsrvr.

Dude CO2 isn't demonized, people are mad at the politicians and lobbyists who used Fox News to dupe people into thinking stuff like CO2 is irrationally "demonized". Or that letting companies release as much pollution as they want was a completely consequence free policy.
