So sad how the third world country of America has some of the weakest, crappiest residential power, but truly developed countries in Europe run 3-phase to pretty much every home.

Feels like a trip around the world into the world of the most beautiful electric motor startups.

oooo, seeing a car v8 powering a buildings chiller units was cool. and no soft starting on an electric motor sounds so wierd (used to hearing them a lot at work)

First time I ever see gasoline automotive engines running a building's a/c chillers!

Why is it satisfying?? Because as men, as astonishment of the highest levels of what's mechanically possible is innate for our being. We are fascinated by technology, the cutting edge and speed, because our future existential selfs can only flourish through being better and more capable, as to continue our bloodlines. Understanding and participating in the cutting edge is thus crucial for us, and it's only not suprising to find a community of men looking at 3 phase motors. Beware the man who is not interested in the cutting edge, since he is not a man.

I asked Chatbot GPT that very question. The AI has some great thoughts: Essentially it was saying the anticipation of seeing the start, the power, the sound of intensity growing, and overall satisfaction of seeing a machine in motion.

The sound is so satisfying

6:35 scary how you can work there knowing that there are many motors and the sensation of suddenly getting sucked by a large fan

When i was on my schools welding shop we had this 16 inch metal cut off chop saw made by everett industries it had a 7 hp motor and it was super powerful everytime it was activated it made a initial hum then as it gained rpm there was a loud screeching from the belt and could be heard from out side the shop

"boom" that instant power 50hz

You can probably do the same thing but incorporate dry power (Belt Driven) hydraulic elevators

I'm so confused why they choose 2 big blocks for a chiller And also were did you get all this amazing footage from?

@NickSilcox3

Жыл бұрын

Are you talking about the GM 454 big blocks? In cities (Philadelphia PA) natural gas is cheaper in the summer and electricity is more expensive during summer as well. So some buildings went with a natural gas powered chiller, since not only cheaper then electric powered, it made Air conditioning for a high rise building, but also domestic Hot water at the same time (engine coolant goes through a heat exchanger)

Just about all of these motors are used for either a fan for an exhaust, or a supply fan for buildings. Others for circulating either hot or chilled water, but for the most part, it’s HVAC related

2 phase?

@NickSilcox3

7 ай бұрын

Yessir, 2 phase power is a 4 wire power feed with (2) separate phases that are 90 degrees out of phase of each other. It was primarily developed to make it easier and add power for single phase motors to start without needing assistance like a capacitor. This was quickly phased out due to 3 phase however some parts in old cities still has 2 phase equipment and 2 phase power feed.

Holy no way! What sort of place is it that uses internal combustion for its chillers just because they want to run on natural gas? And why would they run chillers on natural gas instead of electricity even though it's not even portable (not an RV, etc.)? And even then, RV gas fridges don't use engines, so why are these using them?

@NickSilcox3

17 күн бұрын

Commercial buildings get charged for electrical peak demand. Since natural gas is commonly cheaper in the summer/winter, some high rise buildings opted for natural gas powered screw chillers vs electrically driven to save thousands on their electric bill. Another benefit to natural gas chillers is the engine coolant is also producing domestic hot water (ran through a heat exchanger)

@HelloKittyFanMan.

​@@NickSilcox3: So during the spring and autumn (or at least the most mild parts of those two seasons) they use electric chillers, but then they switch over to these combustion ones during the two extreme seasons (and maybe the extreme ends of the other two)? Also, why does it have to work in this way instead of just the kind of silent gas-powered fridges that you can switch some RV fridges into running on? Heh, permanently installed, stationary engines running a main service instead of as just a backup are so freaky!
