AI Thread Summary
The discussion focuses on comparing two mini split air conditioners with the same cooling capacity but different current ratings. The first unit has a rated current of 9.56 A, while the second has a current of 9.9 A and a rated current of 16 A. The higher rated current of the second unit may indicate it can draw more power, potentially leading to increased energy consumption and higher bills. However, if both units typically operate around 9.5–10 A, the difference in energy use may not be significant. Understanding the power usage and efficiency ratings is crucial for making an informed decision.

Hello,



I am seeing two mini split ACs with the same cooling capacity in two different companies. Both 24000 BTU and Inverter.



The first one said Rated Current is 9.56 A and didn't write Max current or current.

The second one said the Current is 9.9 A and the Rated Current is 16 A.



Does it mean the second one can draw up to 6 A more? (more electrical consumption? and more electrical bills?



Thank you

No, that's just startup current. Look at the power usage and/or EER/COP.

Thank you, but I don't understand. The first one Rated Current is 9.56 and the second one is in 16 A.
 
I don't think "rated current" is an established technical term and they are using it differently.

Though maybe the second unit has electric resistance backup heat?
 
Only if the ductless mini split air conditioner consistently runs at a higher current. If both units normally run around 9.5–10 A, you won’t see a big difference. But if the second ductless mini split air conditioner often ramps up to near its 16 A, it could consume more energy over time.

Here's a video by “driving 4 answers” who seems to me to be well versed on the details of Internal Combustion engines. The video does cover something that's a bit shrouded in 'conspiracy theory', and he touches on that, but of course for phys.org, I'm only interested in the actual science involved. He analyzes the claim of achieving 100 mpg with a 427 cubic inch V8 1970 Ford Galaxy in 1977. Only the fuel supply system was modified. I was surprised that he feels the claim could have been...
TL;DR Summary: Heard in the news about using sonar to locate the sub Hello : After the sinking of the ship near the Greek shores , carrying of alot of people , there was another accident that include 5 tourists and a submarine visiting the titanic , which went missing Some technical notes captured my attention, that there us few sonar devices are hearing sounds repeated every 30 seconds , but they are not able to locate the source Is it possible that the sound waves are reflecting from...
