Hi paul , I know it's not a relevant topic but I have this question : What is the mathematical relationship between wattage and heat or temperature for AC I'm talking about an infrared cooker
@@imme1234 W [JS^-1] ... 'Heat' usually refers to U internal energy measured in J, a surface temp [K] at infrared is chosen to excite phonons to carry heat from the metal pan to the food if not mistaken (or by radiation). If you meant an electric oven cooker you can look up Stefan-Boltzman Law which is T^4 , but bear in mind that relationship by itself won't be useful for efficiency calculations because only a portion of the emission will actually be useful for heating the air/food by convection etc. There's actually a lot going on!
Your explanation and animation are super cool dude. I have seen every one of your videos. The very informative and easy to understand. Upload more are more videos about basis and Arduino. Thank you👍👍👍
Great video - super informative. I haven’t run into any electronic level controls; only magnetic level floats which are pretty much bullet proof. I see these electric level controls being an issue with how they are installed. There are contractors out there that don’t put isolation valves around their sight glass columns. I also see over torque being a problem with them being sensitive electronics (similar to knock sensors for on-the-road engines); most low pressure receivers run between -20” and 50psi, so you don’t have to tighten things too much like you would on steam or CO2 piping.
One thing I don't understand, why connect it to a alarm? Isn't the point of LLS'es to connect it to the system in a way so if level is high, it will run the system in a "overcooling" mode (meaning it will run the system harder than the call for cooling mandates, which of course means that if temperature control is important, you would need a "waste evaporator" somewhere that just dumps the cold somewhere) so to "consume" more ammonia (speeding up the pumps to the evaporator and adjusting the valve), while if the level is low, then cap the system by slowing down or locking out the pumps to the evaporator, to increase the level? And same thing for the receiver, but in this case then control the compressor based on demand so it keeps the liquid level in the receiver good. Of course it would need to raise an alarm if the liquid level is low more constantly, as that might mean there is a leak somewhere, and same if it high too often, because that might mean there is a constriction or blockage in some pipe. But most controllers can raise an alarm if the cooling system is capped too often or run in overcooling mode too often.
The graph in the video is typical for a notch filter (for images google: notch filter q ). A simple notch filter is based on a single resonance. So I guess the sensor emits a signal with a frequency from 4.9 GHz to 6.2 GHz and measures the frequency response to find the "notch".
Hi Paul, how r u? Your videos and explaination are awesome 👌 Can you post video related to BMS for HVAC like DDC controller, IO digital and analog points, etc as I have not found any video related to this topic, Once again thanks for your videos. Stay home and Stay safe.
Hi Vijay. I'd definitely like to cover basic HVAC bms controls in at least 1 video. I'll add it to the list, but it will be a while until that goes into production. Great suggestion thought.
⚠️ *Found this video super useful?* You can buy Paul a coffee to say thanks: ☕

Thanks a lot...
Randomly decided to watch this video, had pretty good chill out time.
I'm an Industrial Electrician. I work with this all the time. We also have a High Level Float.
This is very informative, thanks a lot for ur effort it really helps me as an engineering student.
Thanks a lot.... Best regards from Algeria....

Your animations are awesome. Nice video.

Thanks bro.Good explanation 👍
Please video on resistance, Resistors. How they work. How we choose Resistor for our circuit
Check out NEW resistor video, everything covered! ➡️ ruclips.net/video/DYcLFHgVCn0/видео.html
Hi. Do you have any recommendation on what preventive maintenance procedures are best for this Liquid level switches? Thank you!
Tq bro👍👍
So informative,and as others have mentioned - fantastic animation. You sound a lot like Heston Blumenthal 😀
haha I just checked, you're quite right. Might ask him to dub my videos
فديوهات مفيدة و جيدة شكرا لك .. نتمنى ترجمة الى العربية
Can you please make a video explaining pneumatics? Love your videos, thanks to you, I have started tinkering with arduino and electricity!
Great video as always...keep it up!!!
Informative video, but where the narration describes varying frequency the graphics depict varying amplitude.
The graph in the video is typical for a notch filter (for images google: notch filter q ). A simple notch filter is based on a single resonance. So I guess the sensor emits a signal with a frequency from 4.9 GHz to 6.2 GHz and measures the frequency response to find the "notch".
Great video very informative aa always 👌👌👌
Thank you
Very informative thanks a lot 🤩🤩

Do you have any videos that explain how an economizer or recirculating package on an industrial refrigeration system works? Thanks!
I love your videos please , keep uploading
verynice
Can I ask you a question ⁉️. Is accumulator, liquid reciever, liquid separator ate the same???
So is this just for ammonia or all types of Freon as well?
Which valve can cause liquid trapping, if closed and another valve is not opened
This doesn't apply to anything I do, but its a great video regardless.
Lets make the Water Computer with these
Can also upload a video of transistors.
Thank you

Sir can u make a video about how to make a dc brush less motor driver...

Just chilling out here ...
It's clever but wouldn't it be much cheaper and easier to have a floating bob with two limit switches?
