Great videos! Thank you for putting the time into them. Do you have any plans on doing any videos specifically on glycol loops and ice banks?

[@lukelee6078]

Thank you so much for your nice video.

Thanks for sharing 😀👍

[@josedanielparajonperez6519]

Why do fluids in plate heat exchanger typically flow in opposite direction ? This design of heat exchanger is to provide a thermal equilibrium between the 2 fluids( Inlet and outlet). I asked myself that question 2 days ago as well. Excellent video . Thank you .

[@amedhossain6032]

very nice explanation....

[@waseem639]

Good knowledge thanks,,,

[@thelazycat_]

We use 3 stages plate heat exchanger to preheat the milk/custard/chocolate milk from 4> around 75 degree celcius before pasteurization or sterilization. After the pasteurization it flows back through the heat exchanger to cool it down and heat the cold milk.

[@brentongluck372]

Where do you work at? Kinda curious to see what companies use these

[@nalruponboonsathien1212]

Good job

[@prenitha7909]

Very hlpful vdo😊.can u explain abt the spray chamber???

[@proezastiranas9184]

excelente que buena pagina!

[@Digglets]

nice video. One question: which HX type is appropriate for flue gas base water heating ?

[@kennybush2004]

Fluid flow in the same direction by both fluids will give Thermal Equilibrium

[@jeremysmith2925]

Does it matter if you pipe your hot water in from a outdoor wood boiler to the top port flowing down or do you have to pipe hot water in on the bottom port flowing ip

[@yondaimehokage3343]

is it possible if i were use just high heat rtv or gasket silicone on my custom heat exhanger? tq

[@roberttomsiii3728]

I will comment and participate. The fluids run counterflow to be more efficient. The fluids running Against the Grain causes hottest fluids to mate with the coldest in order to push the two fluids closer to an equilibrium Or that's my hypothesis.

[@pawangupta7649]

Will you make video on Various type of Evaporators?

[@aartikhandare800]

Tell us regarding design of gasket type plate heat exchanger

[@nicholascarr6251]

Before finishing the video I'd say that the reason the flow is flipped every plate is because the heat will be as far as possible from the other heat source so that the water can cool down before it hits the warmer water(in the other plate) coming towards it and thus as you said the colder water will absorb the heat of the warmer plate. Otherwise, the plates will have no thermal difference thus no heat exchange.

[@04DynaGlyde]

I work for the University of Texas Arlington. Our Thermal Energy Plant started turning steam on yesterday 5-21-2020 and today I'm walking the buildings and some tunnels. My question, what should the guys in the HVAC Department check for on the steam tree, guages, pipes, condensate pumps, etc. in each mechanical room once steam is fully back on? Such as checking gauge PSI before and after. Meaning low/high, before Spence and after Spence PSI. And what to look for on a spence/spirax and pilot valve? What about pop offs? I'm still new to this field and want to learn best and safe practices to shut down and especially start up and after startup. Is there a checklist for the steam tree pipes, valves, and pumps, etc. Thank You, Carl Browning

[@1d9b7h8]

Can this heat exchanger be used for domestic hot water in a commercial building ?

only if someone uses this simple tech in PC water cooling. hmmm...... i wonder how good that'd be

[@sureshkumar-ux2nq]

Would like to know what frequency to clean heat exchangers ? How to know when to clean

[@Sam.1981]

More surface area for heat transfer

[@reubs91]

The answer to your question, I'm using water for the process and steam as the heating medium: The water entering the heat exchanger at the bottom has the largest temperature differential and will extract the most energy out of the outgoing steam condensate. As the water rises through the heat exchanger, the water within the heat exchangers upper region will have the smallest temperature differential, this gives small delta T provides the ability to 'control' the temperature of the outgoing water by modulating the heating medium. If it was reversed, you wouldn't be able to control at all, and you would have all sorts of issues with water hammer etc. in the steam and water side as both condensate and water flashed off and collapses.

[@davidmatthews2983]

Why do they flow on opposite directions? My answer: to maximise cooling or heating of medium and maximise most time and size of the exchanger?

[@shannontaylor4384]

I am a maintenance tech for a major automotive manufacturer. We have 1200 Hydrolic presses that use plate type heat exchangers to cool the hydraulic fluid. Water in one direction and oil in the other. My question is should the water that is leaving the heat exchanger always be on top since heat rises or does that make a difference at all since there is so much volume that flows thru?

[@pedrohugoneri]

The port of water/oil come out or in depends the designer, have to many variables. The transfer of heat will happen because the flow, check pump or sometimes you heat exchangers needs to be cleaned.

[@catesolarcatamaran252]

Can I use a stainless stel brazed heat exchanger for salt water 🤔

[@sbullock2976]

They follow in opposite directions to increase their relative velocity to each other, thus increasing the heat transfer coefficient.

[@thelazycat_]

It is just ti have the highest delta at the Tout

[@salimhaddad8289]

Can someone help me? I have 2 chillers and a PHX for “free cooling” im always confused on when to run the PHX instead of the chillers. I need a cheat sheet that says medium temp- low humidity= run PHX or high temp high humidity= run chillers I know I have to factor in wet bulb and those things. Thats why it gets confusing for me. That’s why I was hoping someone can help me understand

[@RAGNES7]

also, you promote Defoss, quite a lot. but i dont see any courses with certification option on the website as mentioned in this video couple of times 8:55 am i missing something here?

[@EngineeringMindset]

There is an exam at the end of each class :)

[@RAGNES7]

@@EngineeringMindset oh that's nice. So, that means all course offered have certification? Also, what will the certificate say on it, and what's the validity of it? How to prove it's authencity (other than knowledge, cuz I'm sure I'll be learning it all)

[@satendrapatel6441]

Sir I am using glycol water chiller of 5 TR for milk pasteurization and during this process I want to cool my milk to 4 'C but the temperature of milk is not maintaining as I want to maintain. I am using around 300 l of glycol water solution but temperature of milk maintained around 18 'C so what are solutions so that I can maintain 4 'C temperature of milk

[@azamgroup4544]

[@agustinushadi6604]

Please make video in indonesia langguage.

[@Jedward108]

The fluids flow in opposite directions because it's like a head-on car crash which has a lot more energy than if the cars collided whilst going in the same direction.

[@karanpunjabi3077]

To achieve maximum LMTD

[@souravkumar2522]

I have a big confusion plz solve it .. I see two types of plate heat exchanger , first type have all 4 nozzles is same side or same face , but second type have 2 nozzles on one side and 2 nozzles on opposite side of plate heat exchanger ....what's the cause???

[@EngineeringMindset]

Hello, please watch this video, we covered this here: kzbin.info/www/bejne/mKOWmJ6ojbmgmrs

[@MrGinotonix]

The one with 2 nozzles on either side is probably a two pass plate heat exchanger. Search it!

Because heat always travels towards cold? And high pressure ( hot) always flows towards low pressure ( cold)? I dunno
