One year ago,I worked in Production Department,which requires me to deal with Production Output everyday and it was kinda boring for me. From then,I found your channel, studied on HVAC system and make your video as my primary reference regarding Chiller operation.Now I've become a Facility guy in another Company thanks to your wonderful videos. Please keep producing videos like this. Your videos help me to change my life.

@abdullahalabdulhadi5079 2 года назад

Thank you for the video. Does refrigerant enter the evaporator as liquid or a mix of liquid and vapor?

@christopheradam1969 3 года назад

Have you done a video about the operation of different types of Evap, Flooded, Spray Flooded, Plate etc?

@EngineeringMindset 3 года назад

Flooded and plate yes. We also have the chiller terminology video which is a gold mine of info.

@davidwyness7746 3 года назад

Thanks for the video. For the plugged pipes, how would you identify which tubes are leaking water to the refrigerant, especially if it’s a smaller leak?

@EngineeringMindset 3 года назад

You test the tubes and if it can't hold pressure then it has a hole

@waleedraza8374 7 лет назад

Thanks for such a brilliant presentation.I have Some questions How refrigerant absorb all the heat ? Which thing is in the evaporator that made the refrigerant to suck all the heat from chilled water? As the tube contain the water and refrigerant is all around the pipe how come the absorb heat did not affect again to the pipes?

@EngineeringMindset 7 лет назад

Hi Waleed, The refrigerant has very low boiling point and when it evaporates it takes some of this heat with it, much like it you boil a pan of water, the water evaporates and will carry the heat away as steam. The only thing that makes the refrigerant "suck away" the heat is the temperature difference and specific heat capacity. Hot always moves to cold.

@samuelmajekodunmi586 7 лет назад

I love your presentation. Well done. If I may ask, what are the likely causes of suction pressure fault in a chiller? Thanks.

@EngineeringMindset 7 лет назад

Hi Samuel, there could be many reasons. Probably there is a blockage, over/under charged with ref gas, wrong gas, low detla T, broken sensor. It would be best to bring in a service specialist. If you do, make sure you see what they do and ask lots of questions to learn.

@EngineeringMindset 6 лет назад

We just covered chiller faults in our recent video! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Zu0LVVNNVSw.html

@alejandrogalasso2352 3 года назад

Great video! You say that chilled water enters the evaporator, but I thought the water in it would come from the terminals in the building, i.e. it would be water carrying heat collected from the ambient. How does that work?

@jbaker8871 3 года назад

Yes chilled water enters the return side of evaporator from a terminal and leaves chilled on the supply side of evaporator to a terminal. Heat is transfered through refrigerant to condensing barrel.

@mohammedyaseen1894 7 лет назад

Thanks a for presentation.may I ask you for the types of refrigerant used in these types of chiller units,and their properties, especially boiling point of refrigerant.

@EngineeringMindset 7 лет назад

R134a is used on many chillers, check the website of manufactures such as Trane and Daikin Applied. You can find the data for the refrigerants by googling "R134a properties"

@vzclubbie 7 лет назад

If the expel its heat in the pipe, would it possible that there can be moist in the evap pipe that possibly be mixed in the refrigerant?

Hi, what caused the existing ice flakes from evaporator sight glass ?

@michaelsalinas8202 5 лет назад

I'm a bit confused you are pointing to evaporator in the diagram at 1:03 located on the bottom looks like the Condenser is moving fluids into the AHU.

@hvinceac9211 7 лет назад

well done very well done comma I have a question. In a chiller with with refrigerant 123 is it possible that air in the system will also cause a surge.?

@EngineeringMindset 7 лет назад

HVince AC yes it could lead to surge. if the refrigerant level was low also or if non compressible fluids entered the compressor.

@hvinceac9211 7 лет назад

The Engineering Mindset thanks for the reply.

@TheAkshay09 7 лет назад

5:30 I think you meant 'the chilled water leaves the evaporator at 6 degrees celsius'

@EngineeringMindset 7 лет назад

Well spotted. Thank you. Yes it should enter at ~12*c and leave at ~6*c depending on the setpoints.

@mackenziemisner4815 5 лет назад

@michaelmorrison5675 5 лет назад

@nburaq 5 лет назад

According to animation in this video evaparator is shown at bottom but in your 3d drawing it was located at top part of chiller and bottom as condenser right?

@alfredomarquez1485 Год назад

Wait I thought the refrigerant was in the copper pipes and not the water.

@Jason-wc3fh 3 года назад

I can't imagine the pressure reliefs for the refrigerant would just vent to the atmosphere, that would be completely against the law over here in North America. At the very least, it would have to vent into some sort of a sealed tank/cylinder.

@EngineeringMindset 6 лет назад

More paases means more heat exchange as larger surface area. That also makes it shorter in length although larger in diameter. More chance for the heat to be full utilised.

@ajithkhan7314 7 лет назад

at 9:15 you said "chilled water entering into the evaporator.." but correct me if iam wrong, actually the hot water is entering into the evaporator from AHU and gives up the heat to cold refrigerant and get cooled ans leaves it as cold water. So HOT WATER IN and COLD WATER OUT. Right ?

@EngineeringMindset 7 лет назад

Ajith Khan correct, but the water in that loop is referred to as the chilled water loop regardless of temperature.
