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?

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?

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.

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?

Well done! Now if I can get my junior engineers to stop playing with their bloody iphones long enough to learn how 'our' chiller system works, it will be a good day. How they passed thermo and heat transfer is beyond me.

I have a question. Within the evaporator there is gas and liquid. Gradually the amount of liquid will full the evaporator, so how could to maintenance the amount of liquid in the evaporator? Thank you.

Videos are great visuals are very educational. just started going to school for refrigeration machine operator engineer (NYC) and your videos put images to all the book words
Thanks a lot keep'em coming

Please let me get lost already. Does the device used in water/gas (cooler controller type R32, etc) or water/water and water devices have water or gas flowing in the evaporator? Greetings from Poland

I am currently working in Dubai and doing condition survey on buildings, till now i havent worked with chillers, but only district cooling system, ur videos helped me a lot to get clear pictures

sir please make a documentary on one famous project hotel or hospital for how hvac system work with proper amount of heat calculation.
sir this might be very useful who can't afford

Hi love your videos is this a flooded evap can you do a video explaining this. Also I might be wrong did you not say in this video you had a return and feed temp both at 12c?
Thanks

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.

Thanks for your video, I have one doubt how does Liquid Refrigerant move towards the evaporator at a higher level, what's the driving force to move to higher elevation.

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?

Is it safe to cut into an abandoned Chiller to remove the copper tubing with a set of cutting torches? Is there flammable gases inside the chiller? Thank you

Your videos are well-done and have helped me learn the basics of refrigeration and chillers. Do you have any plans for a video about air-cooled chillers?

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.

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?

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

Hey Paul, your videos are so good. have helped me learn so much as an engineer. Are you thinking of going a domestic / drainage public health series?

i have seen lot of videos of refrigerant but i have never seen R22 or R410A as refrigerant in HVAC. is there any other reason beyond economically?

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?

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

Very useful video, water entering in the condenser is from the cooling tower, how about water entering to the evaporator? thanks
