I just replace a 600 amp circuit breaker on a Trane chiller yesterday. I've been an electrician for 30. It very interesting to me how the mechanical side of equipment operates.

Rocking the YT in the thumbnail. Therefore you get a thumbs up from me 👌🏻🙌🏻 edit to add - if you really want to blow your mind, look up the YZ. Chillers have gone full circle with refrigerants. We have three going in the hole in about 2 months time.
Sir please make a video on fault analysis in electric transmission line and surges travelling in long transmission line .... With your visual intuition it will be very helpful
Can you please make a video on how mobile phone controlled smart bulbs work? Thank you so much for your amazing videos, I have learnt so much from them!
In minute 6, it is mentioned that chiller efficiency is lower when approaching full load. As far as I know, for centrifugal chillers, the best efficiency is when they are running at 100% chiller load. Kindly correct me if I am wrong.
Hey guys is it possible to use VFD motor as a synchronous (Constant speed) motor in chiller during the peak load months (by bypassing VFD related Power electronics).
Yes, VFDs will often have a bypass mode to allow power to bypass the power electronics in case the VFD fails. If you need to operate at full speed anyway, it's more efficient to bypass the VFD since there are some losses in the VFD. Idk if that's an operation that can be automated easily however.
Which of the following Chilled water system mechanical component has the highest level of individual Coefficient of Performance (COP) above 300 kWr? Chiller,cooling tower or chilledwater pump
1kw of electrical energy is used tk collect 5kw of thermal energy from the environment. We are just using the electrical energy to collect thermal energy from lots and lots of air/water and store it in a much smaller volume.
As the Channel has mentioned, Compression Heatpumps such as this one can reach COPs of greater than 1, which often confuses people. COPs are calculated much the same way classical efficiencies are calculated, but precisely because they can exceed 1, they are not called that to not cause confusion. A heat pump doesn't generate heat specifically, but rather moves heat up a temperature slope. Think about temperatures as hills, heat always travels down hill, from high temperature to low temperature. A heat pump moves the heat against this gradient and uses energy for that. The reason for why it uses energy are a bit more complicated, involving entropy and other themodynamic principles. Now, for various application, the useful thermal unit is different. Either you need the cooling, like in a refrigirator or you want the heat, like a classical compression heat pump for our house. Depending on what energy you want, you disregard the other source. For an instance, the backside of you refrigirator gets warm if it's running. That's because the heat from the inside is move out. But since you don't care about that additional heat in your room, you disregard it and calculate the performance only using the useful cooling energy. If you want to heat your rooms with a heat pump, the principle is opposite, you want to have heat and you take it from outside, either from the air or from the ground. But since the low temperature thermal energy of the air of ground are nearly infinite, you disregard them in the calculation.
5kw of heat is being moved from the cold side (cooling it further) to the hot side (heating it further). It takes 1kw of power to move that 5kw of heat. therefore the hot side has to dissipate 6KW of heat in total. while 5KW is being extracted from the cold side.
Refrigerators are called heat pumps. An electrical resistance heater simply convert electrical energy into heat and is 100% efficient, its cop is 1. Heat pumps move heat from cold region to hot regions using electricity or other forms of energy. -273 C or 0 k is called absolute 0, at this temperature there is no heat remaining in the region, theoretically as long as the temperature is above 0 deg k, there is heat energy in the region. That is why reversible ACs are about 30% more efficient in heating the room compared to using electrical resistance heating because they use electricity to move heat from cold region to hot region not electricity converted into heat.

Think I can shout you an americano.
at 3:03 there is no need to add 273.15 to both sides of the operation. the delta c is the same as the delta k, you just added steps needlessly.

We have lots of chiller videos if you'd like to learn more
@@EngineeringMindset I'll check those out. Do you have any videos on the programming systems? I know every company. But are they similar?
@@bah5310 600amps. wow. I mean WOW.
👍🏼 The world needs more people who understand the design, installation, and operation of high efficiency chillers! Have at it, gang! 😎✌🏼
Why?
Because énergie is more expensive.

As a mechanical engineering student, I really enjoyed this video
Just refreshed me on my lessons from school. Great video bro.
Thank you. For sharing these knowledge

Thankyou so much for this video
What an explanation 👍.keep it up
I love your videos ❤️
Good job
Great
Can you make a video for operation parameters maintain during operation like sst, ssh, dsh, approach etc with readings
Chiller is a Super amazing machine
In your video how calculate COP of chiller pl explain formula values.
Awesome
Please get into more details of part load efficiencies of constant and variable speed compressors.
In minute 6, it is mentioned that chiller efficiency is lower when approaching full load. As far as I know, for centrifugal chillers, the best efficiency is when they are running at 100% chiller load. Kindly correct me if I am wrong.
They do operate best at full load, however not when a VSD/VFD is installed
Hey guys is it possible to use VFD motor as a synchronous (Constant speed) motor in chiller during the peak load months (by bypassing VFD related Power electronics).
Yes, VFDs will often have a bypass mode to allow power to bypass the power electronics in case the VFD fails. If you need to operate at full speed anyway, it's more efficient to bypass the VFD since there are some losses in the VFD. Idk if that's an operation that can be automated easily however.
@@samfisher874 Thank you for reply.
Please tell me what is the use of free energy generator which is made of magnets.shaft and bearing etc.
It's to extract money from morons who think there's such a thing as "free energy".
Which of the following Chilled water system mechanical component has the highest level
of individual Coefficient of Performance (COP) above 300 kWr? Chiller,cooling tower or chilledwater pump
I have a question. How can 1kw of energy can produce 5kw energy. Is it different kw?. It got me confused
1kw of electrical energy is used tk collect 5kw of thermal energy from the environment. We are just using the electrical energy to collect thermal energy from lots and lots of air/water and store it in a much smaller volume.

Less electrical energy used to CONCENTRATE heat energy from the environment (which is not created but relocated)

I suggest a videp for solar power. Pleaseeee

what does 'hvacr' in the video headline stand for?
Heating ventilation air conditioning refrigeration
@@EngineeringMindset Thank you! I have just started learning HVAC engineering in Sweden and the 'r' at the end confused me.
@@anbtebist5961 R for refrigeration
Please Could you explain about electric car that why it uses AC motors.
Pl tell Volume flow rate value of 0.0995 M3/s how????
First comment
Well done
But always the efficiency should be less than 1, how is it possible to extract more power from a given amount of input power?
Discussed in comment below
First
2nd but very close

Nice!
