Good evening. I want to ask something about compressor. Maybe one of you know about this. I have problem with my ammonia refrigerant compressor in plant. This is multistage compressor and driven by steam turbine. The speed (RPM) of the compressor is decrease time by time, and the valve of steam turbine is full open now. When i collect the data of the process, i find that vaporation in the suction compressor is increase, because any trouble in heat exchanger. Is that can make the speed of the compressor decrease? Is that choking?

Amazing videos, I work on a large cruise ship, we actually have 5 chillers that work in sequence. Huge power plant. And the compressor itself is equipped with VGD difusor.
And of course we use sea water inside the condenser to remove the heat of the freon.
I am relatively new to this position and your videos makes everything much much simpler.
Keep on the good work

Your explanation using the cylinder reducing the volume of the refrigerant is how a positive displacement machine works. Centrifugal compressors are not positive displacement machines. They are dynamic machines. They do not compress the gas. They raise the pressure by accelerating the gas.

Your arrows are pointed in the wrong direction. Tower water pumps push water into the chiller not towards the cooling tower. Also the chilled water pumps push water through the chiller to the AHUs. They dont pull water from the chillers.

Very interesting to watch how a large scale centrifugal compressor works. I should point out, however, centrifugal force is a direct consequence of centripetal force (the actual force causing something to rotate) by newtons III law.

Could you do a video on all Centrifugal compressor internal components and break down as I've never seen the internal workings of the high and low speed gears, wheen eye seals and thrust bearings.
Thank you

Hi, Sir.
Videos here were very informative. I really love watching it. Hope you'll make videos for the different type of compressors particularly scroll, danfoss turbocor and screw. Thank you.

Hi, as always, great video, question, Cooling temperature control is done through the compressor input spindles by centrifugation, but how is it controlled when the compression is by pistons?

The alternative to the centrifugal compressor is the twin screw compressor and they are both used on chiller systems which are only used on large buildings like sports arenas?

Typo in last slide. Last slide is power not work and enthalpy unit is kj/kg not kj. kg. Excellent series. Great explanation. Thank you so much for the effort.

Really really helpful,
One request Paul, could you please add video of Types of compressors with recommended Chiller capacity range?

Actually W [kJ/s] or the same [kW] is not a work itself, but power. Anyway, thanks a lot for your valuable efforts. Very good job!

Im thinking of a chiller and cooling tower for my house. Air conditioners are too small and undersized in my opinion

How does the diffuser slow down the air if its just a small gap? Wouldnt that increase the velocity?
