After years of doing residential a/c i got a job learning chillers and boilers starting next week. Nice explanation of the mechanics ty

[@MEPAcademy]

Learning about chillers and boilers will definitely expand the demand for your services. Good luck, and thanks for watching.

Brilliant! Thank you for de-mystifying chillers, MEP Academy!. The way you connected it to the conventional refrigeration cycle was the key to my comprehension.

[@MEPAcademy]

Thanks for Watching.

[@sharonpaul2824]

Concepts explained crisp and clear! Wow! I finally understand how Water-cooled chiller works!

[@MEPAcademy]

Thanks for watching.

Clear, concise, great graphics, accurate and everything I'm looking for! Subbed.

[@MEPAcademy]

Thank You.

Beautiful video am learning about chilled system as i have being doing spilt on fridges for 2yrs now

[@MEPAcademy]

That's great. Keep learning as the industry needs more experienced technicians.

[@nabeelahmad195]

This is fantastic work! I mean I've been scavenging through a ton of videos... Looking for some simple, yet detailed video on how utilities work. I've just started with chillers now and I think I'm gonna go through the entire playlist! Notes on the goooo ❤️❤️ I've started a new role and in legit struggling. So this is really good for me. Thanks a million!!

[@MEPAcademy]

Glad it was helpful! Thanks for watching.

Thank you for reminding us to be aware of where the subtitles and images may overlap. We'll try to be careful on future videos.

There's a thing I don't actually understand. How does the water coming from the cooling tower cool the refrigerant enough? The water enters the tower at 35 degree C and leaves at 29. I mean 29 is still a high temperature. What is the refrigerant's entering and leaving temperatures in the evaporator?

[@MEPAcademy]

Remember that you need a difference in temperature to move heat from one location to another. The greater the difference or Delta-T, the greater the amount of heat that can be moved. The condensing temperature of the refrigerant in the condenser can vary, but 95F-100F (35C-38C) are good examples for a water-cooled chiller.

[@kaan2215]

@@MEPAcademy I don't understand. As far as I know, boiling points of R32 and R410a are about -52 degree C. The temperature of the refrigerant needs to drop to -52 before it leaves the condenser, right? According to the heat transfer principle, how can you do this by using 29-degree air or water? At best, in the condenser, you can drop the temperature of the refrigerant to that of water or air which is 29.

[@MEPAcademy]

@@kaan2215 You're thinking is good, but you're forgetting about the pressure. If you look at a refrigerant chart for say R32 and a condenser pressure of 280 to 320 PSI (19.3 to 22 Bar) you'll get your temperatures. The work of the compressor raises the pressure of the refrigerant in order to make it useful for absorbing the heat from the tower water. Hope that helps.

Where the chilled water is going can you explain

[@MEPAcademy]

The chilled water is produced and delivered to air handlers and fan coils. The air handlers and fan coils absorb heat from the spaces, thereby cooling the room air. The air handlers and fan coils have chilled water coils. See our other video on how air handlers work. kzbin.info/www/bejne/e5-Ve39-q7eUec0
