Even though chilled water systems are a new idea to most people, the concept has been around since the time of the ancient Romans. To cool their buildings, the Romans would run water through the walls to cool the space inside.
It wasn’t until 1902 that Willis Carrier invented modern air conditioning. Then in 1926, Carrier invented the first centrifugal chiller, which made it possible to provide large-scale air conditioning for buildings.
Since then, chillers have undergone much innovation and there are many diverse types of chillers. However, the purpose of a chiller remains the same: To remove heat from water.
Chilled water systems provide cooling to a building by using chilled water to absorb heat from the building’s spaces. At the heart of the chilled water system, a chiller removes heat from water by means of a refrigeration cycle.
A chilled water system’s refrigeration cycle works by removing heat from chilled water in the evaporator of the chiller. The compressor is what drives the entire process. It also uses the most energy in a chilled water system.
In the condenser of the chiller, the heat is transferred to the condenser water, or directly to the outside air (we’ll talk more about this below).

Good

[@astondynamics6976]

Explain very clearly 👍

[@augmintech]

thank u

[@miladmajdi6720]

Thanks. What about supply line (from chiller) friction loss and terminal load pressure drop?

[@augmintech]

This is a 1/5 of a complete project. All the losses are taken into consideration in the complete project which is there in our main course

[@ajaykumar-lf8dh]

Great video sir.
Please make a video on electrical load calculation for hvac

[@augmintech]

Thank you Ajay
We already have a free course in our website about air terminal design
Check it out

[@rat123mumu]

What about system static head pressure?

[@ijasahmed6712]

what about the vertcal head

[@engineerane]

How to find NPSH on site

[@ahmedadam933]

what is the presentation app used , if you may ? Thanks

[@augmintech]

ppt

[@khaleelahmedshaik7857]

Nice info but have some questions
1. U have only considered from ahu return side through pump upto chiller coil..from chiller coil upto ahu supply also is not considered. Why? Please prrovide reason..since there are also valves n fittings in that ,which is also part of critical path
2. From poiny E-H, near pump header u took elbow, it shall be t and reducer of reducing t in practical

[@augmintech]

This lecture is a part of the main course. 1 of 5.

[@kamalgopu6757]

100 ton chiller the primary pump is only 2 HP ?

[@zamnadmp6870]

You need calculate the friction loss in supply line also

[@augmintech]

For supply line, friction and other losses are taken care by secondary pumps which is another part of this project and is a separate video.

[@zamnadmp6870]

@@augmintech kindly upload rest of video. All of them are misunderstood by this video.

[@Mohamedyasser-to6nh]

Excuse sir, I think Supply line should be calculated or this calculation should be multiply 2 .you calculate for return line only .

[@Naa529]

Hi.. I appreciate your efforts.. Such a very good Explanation.. Can you tell, why the friction loss csnt be more than 4 ft/100 for above 2" pipes

[@syedashfaq1359]

Anyone enrolled in HVAC design course?

[@hvacdesignsolutions]

How can you offer courses in HVAC hydronic design, if you don't understand basic HVAC design principles. You've made a fundamental mistake in your 'critical path' pressure loss calculation, which means the pumps are undersized.

[@augmintech]

Dear Damian
Actually this is one part of 5 part video series
What you are assuming mistakes are actually included later in other videos. I understand few pressure losses are not shown here in this video but as a complete 5 part videos series includes everything. It includes even what you are assuming as mistakes here.
Apart from piping losses, other losses can be distributed among primary and secondary pumps. So its a variable combination at advance level. I hope you get some idea what I am referring to .
