Sir
I am just a beginner in HVAC field and your videos are very helpful for learning. Sir i have a doubt. From where this chilled water is supplied. In video its showing, supply and return is connected with evaporator. But my question is inorder for chilled water to circulate it should be supplied initially from some point. Right?
So, sir from where does it come from. Please answer. I watched so many videos still not getting an answer for this.
Thanks

I have an Aqua Euro 1/4 hp chiller, and the regulator has become non-operational. Is there a video, or pictorial guide in re how to replace the regulator? I have the replacement part. It is for my 120 gallon Discus tank in the garage; thus the water temp. is crucial. The space for working with the chiller is limited as it is in the rear of the tank where the chiller sits is near the side garage wall. Any suggestions?

You seem to have missed out a unique category but really common set up. It is mostly found in hotels, individual rooms are equipped with self-contained air conditioning units but the condensing unit is the refrigerant pipe that runs inside a larger water pipe that goes to the spraying tower. In this setup, there's no refrigeration of the water, just the water tower equipped with water pumps.

Can someone help, we have this chiller on our building and on our room, its not getting cold like before. Ac technician said they already cleaned the filter, what other factor could they consider? sadly the ac tech is not cooperative, since this is free maintenance service.

Hi there. I believe you have the piping from the chiller to the pumps switched around like in your other video.
Correct me if I'm wrong. I'm an Elec PE for an MEP firm trying to get a basic understanding of HVAC systems.

How much should be the Grill temperature of an AC i e temp at discharge in room.
The ACi have bought recently is showing 20. 3 deg c and i beleive this is too high.
Does the Grill temp vary with the room temperature

Maybe good to add also the possibilities of cross stream heat exchangers, keeping heat in when needed and als create a possibility to use free cooling instead of just the DX to do so.

Is the difference in temperature of hot air coming to cold water enough so that energy could be converted to electricity, or dumped into a battery instead of dumping into the atmosphere?

If floating foundation on water then it can cool building, fighting fire, and antiprojectle from missile to airplane because it can had up to million psi system if needed

2: 51 Is there a particular reason why buildings have the same amount? Is it a manner of volume of medium displacement needed? Can someone explain?

Thank you for the helpful videos! Is it possibly to convert a 4 story office building, 95K Sf from cooling tower/AHU system to RTU system?

What you were to run water thru the window frames keeping at a pressure so that it evaporates and send it to condenser inside the building.

This could balance department if transportation without cost of gasoline and kept earth orientation the way needed in case missile strike

Any help is appreciated, would an AHU be connected to a RTU to distribute the conditioned air, or would the RTU do all of this itself?

Did the VRF system videos get taken down? Was trying to find the playlist for a coworker. Thanks again for all your hard work!
