In some HVAC systems, the chilled water pump may serve multiple AHUs. If turning off the AHU means that no cooling is required in any part of the building, it may be reasonable to turn off the chilled water pump to save energy. However, if there are other areas that still require cooling, you should keep the chilled water pump running.

The Chiller is using the water from Cooling Tower to Cool down the temperature of the Refrigerant. In Air Cooled Chiller, the chiller using Air to cooled down the Refrigerant Temperature. So, Cooling Tower is much important Component in a Chiller system. How Cooling tower works and How the water from the Cooling tower is used in the Chiller these are explained in the previous video.

Do you need the industrial chiller?

The Refrigerant is going inside the chiller between evaporator and condenser. I have explained this in the chiller working principle video. The link is here Chiller Working Principle ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HAxv0T3NVe4.htmlsi=AT5TjcffolLWGnig

It's based on the size of the area where we want to cool down. If the area is small, we can use FCU which is like AHU but small in size. FCU uses the chilled water from chiller and blows the cooled air. but, for the largest areas, AHU is the efficient one to cools down the room temperature.

The suction pressure can vary depend on the design and load.

Suction pressure should be 30-40psig and Discharge pressure should be 140-180psig

Actually the condenser water pump is pumping the water from chiller to cooling tower. The chilled water pump is pumping the water from chiller to AHU. The one pump is doing the both jobs. In some of the chiller plant we can see two pumps called Primary pump and secondary pump. Primary pump is used to pump the water to chiller and secondary pump is used to pump the water to AHU or cooling plant. But in some of the plants only primary pump is enough to pump the water to chiller and AHU or Cooling tower. Here I have mentioned primary pump chiller plant. Thank you asking your doubts. If you need more clarification please don't hesitate to ask.

@@zebralearningsenglish-pn6fl please correct in the animation also inlet

I think inlet is from downside and outlet is abov

@@zebralearningsenglish-pn6fl ok thanks

Thanks for letting me know. Actually I know that already. But I wanted to keep the pump in horizontal position that's why I made this animation like this.

It's wondershare filmora to make animation and video editing.

Yeah, that's I already mentioned in the comments. For the design, I changed that. However, the working principle is the same.

I can explain, bro but this channel is only for HVAC and Electrical content.

Yeah, I wanted to keep the pump in Horizontal direction only. That's why I designed like this. Thank you for letting me know.

The water entering the cooling tower at 35deg C where is that coming from?

The chilled water circulates inside the pipelines. But when there is a need for water due to water leakages, the water will be added from the makeup tank.

But how did the water get into the chiller in the first place that’s what I don’t understand Where did the water going into the evaporator to produce the chilled water come from? Is there a tank in the AHU that is sending water to the chiller? I understand the closed loop but the video didn’t really discuss how the water got in there in the first place

Now I can understand your question. There will be a tank called Makeup tank. From that tank, a pump is connected to the pipeline of the chiller. From that tank, water will be filled throughout the chiller pipeline first. Then the water continues to circulate in a closed loop. If there is any leakage of water in the chiller pipeline. From the makeup tank, the water is again added to the chiller pipeline through the pump.

Thank you for considering me for the opportunity in your company. I appreciate the offer, but at the moment, I've recently been promoted in my current role, and my commitments here are a priority. I'm also deeply passionate about teaching, which is why I dedicate time to creating educational HVAC content on my RU-vid channel. While I don't have extensive practical experience, my strength lies in theoretical understanding. Unfortunately, relocating isn't feasible for me right now. I hope you understand, and I'm grateful for the offer.

Hello

@@nickyotieno9255 Hi

Can you please explain? I have checked it's gong in correct direction.

The inlet water for cooling tower must in the top 35 c. Then the outlet must be in the bottom of the cooling tower 30 c ., and so on for the AHU.

Yeah, I checked now. You're correct the inlet for cooling tower should be at top and outlet should be at bottom. Thank you for letting me know.

The direction is wrong it’s supposed to go in 12 to 6 .. not 6 to 12

@@Dirtydollars020 6 ºC to 12 ºC is the correct one. The chiller will send the chilled water to the AHU and AHU will use that water and sends out at 12 ºC.

The flow direction is correct. Only the inlet and outlet position is wrong. That I already mentioned it. That's for the design I changed that. Next time it will be perfect. Thanks for your comment.

To make the pump horizontal position I designed like this.

Thank You 😊
