    Very good basic video, I am in water treatment. The mechanical knowledge is what many building engineers are looking for. You can take this video as far as one wants to go. I am seeing more and more scaled condenser tubes in the industry. This year alone, I would say I have witnessed more Eddy Current Testing than past years. Centrifugal, Reciprocating and Screw chillers is a good idea to discuss the advantages and disadvantages of each. Good stuff, young engineers need this information.

    Also noteworthy is that CHW loops and CW loops can be drawn OR pushed through the equipment. If your CWS comes out of the tower, then through the pump, then to the chiller - it is a drawn loop. if you return CHW from the building, run it through the pump, and then the chiller - you are pushing water through your chiller. Then you also have primary and secondary CHW pumps and constant volume bypass headers, etc, etc...

    on the AHU - the coil connections can be configured in a variety of ways. The supply connection is not always the bottom connection; but it IS ALWAYS the connection on the "leaving-air" side of the coil. You want your coldest water to interact with the incoming air last in order to maximize the heat extraction from that air.
    Keep in mind none of this equipment actually "cools" water or air. It "extracts heat" from water and air, resulting in a cooling effect.

    hi, great presentation, great.
    I'm barsileiro, live and work in Rio de Janeiro, I had a doubt Evaporator is not above, because the compressor suction in this cooller above, is what it seems! this is a chiller daikin macquay, and usually the condenser is below the evaporator, because the compressor is directly connected to the evaporator.
    my congratulations and Thanks for listening and post more videos.

  • @CallegriaofSoulbound

    The Air Handler takes chilled water (generally 45°F) from the evaporator barrel. This water is in a "closed loop system" meaning that water cannot escape. (although through maintenance and time some does and a make-up system will be uses here as well) This closed loop system will cycle through the building collecting the heat the air handlers are removing. When it gets back to the evap barrel the heat will be transferred to the refrigerant.

  • @hjeangful
    @hjeangful 11 лет назад

    2° When you compare the cooling towers, indeed they are not matching, the left one is called an open cooling tower exactly what you explained before, the right one is called a closed cooling tower, the water is circulating on top of the cooling tower in a closed coil (so the name closed cooling tower). There is a basin full of water at the bottom of the cooling tower; this water is continuously pumped to the top of the CT where nozzles are spraying the water on the condenser water coil.

  • @juanzingarello4005
    @juanzingarello4005 9 лет назад +3

    I always tell my interns this. Supply lines head towards the load. Return heads away from the load. Condenser water supply goes from cooling tower to chiller. Chilled water supply goes from chiller to load.

  • @hjeangful
    @hjeangful 11 лет назад

    3° The sprayed water is evaporating and cooling down the condenser water, the excess of water is dripping back to the basin. There is also a fan sucking air from the opening at the bottom and blowing it (hot and moisturized) at the top of the CT.

    @TheControlsFreak  11 лет назад

    I was at a Female Correctional Facility in Ocala, Florida that used underground water and heat exchangers for the water source heat pumps. A real energy saver. Though at the time the plates were getting changed out because they litterally were creating pools of water on the floor from all the holes. ;)

    4° When you draw the pipes, please consider that the water pipes are always connected at counter flow with the refrigerant (refrigerant is going down in the condenser as it condenses and going up as it boils in the evaporator) so exactly the opposite of what you draw there.
    Consider all these remarks as constructive

  • @TheControlsFreak
    @TheControlsFreak  11 лет назад

    DUDE! That is exactly what I thought when I started doing controls and came across my first cooling tower. I knew those big plumes were steam, but never knew what they heck they could be cooking that would need that big of an exhaust. LOL

    The refrigerant will transfer this heat to the condenser barrel which will transfer the heat from the refrigerant to the condenser water. The condensing water will go out to the water tower and be transferred to the air.
    The water in the closed loop system will also need to be treated. Since most chilled water piping is in black iron pipes the water will need inhibitors. Inhibitors prevent the iron from rusting in the pipe.

  • @outofreach024
    @outofreach024 11 лет назад

    you can also pair cooling towers with heat exchangers and water source heat pumps to provide what is essentially called "Cooling Water" to units in a building achieving the same principal results. In this situation I've also seen cooling towers and Tower Water Loops substituted with Well Water Loops to take advantage of naturally occurring (free) "cooler" water - which is simply pumped through the primary side of a heat exchanger.
    Theres all sorts of neat shit out there...

    It is also important to clean the tubes of the condenser barrel once a year to remove the scaling before it clogs the tubes.

  • @CallegriaofSoulbound
    @CallegriaofSoulbound 12 лет назад

    No. The cooling tower uses water that goes through the condenser barrel. This water is called condenser water. As this water is run through the water tower some of it will evaporate. Replacing the evaporated water is required to prevent it from eventually all evaporating. To do this we use a pipe system called make-up water that is pulled from the buildings supply water system. Because this water has minerals in it the water has to be chemically treated to prevent "scaling" on your tower fins.

    Hey control freak, i just wanted to make a correction about the motor, you said it is going to have some "gearing" to operate the fan. This is incorrect. With a motor vertical motor like that it is going to have a pully on the motor shaft and fan shaft and both be connected with a belt. If the motor was horizontal then the motor would be connected to a gear box with a drive shaft, and the fan shaft would be connected to the top of the gear box.

  • @TheControlsFreak
    @TheControlsFreak  11 лет назад

    Thanks for the comment, James. For now I am going to disagree with you that there 'never' is a situation where the fan is turned by something other than a belt. Maybe the one in the video, sure.
    But I have seen cooling tower fans that are 20+ feet in diameter and no belt I know is going to be relied on to spin that puppy!

    Sure... what you said. I know I messed up on the placement of the Condenser Water Pump, however the wording of Supply and Return should be used in relation to the Condenser Water Equipment. That usually means the Cooling Towers... and their job is to Supply cooler Condenser Water to 'whatever' is on the other end. A chiller, a heat exchanger... anything. The water that Returns back to the tower is well Condenser Water Return.

    Hi,
    You mentioned the reason why CHWS should be in the bottom of the AHU and the CHWR to be in the top. Is this applicable to the Chiller also? I mean, the CHWS leaving the chiller should be from the bottom pipe and the CHWR to the chiller should be the top pipe?

    awesome show...but probably their is a small defect in this installation ...in video shown both pumps of circulation heat and cool water are installed in return network installations..it's obligatory to placed pumps on return network or in other side ? my opinion is to inverse installation because velocity of discharge water is Superior to velocity of suction water for this argument transfer heat and cool within evaporator and condenser cannot correctly carry out . that means long time running of chiller .

    Hi, nice try.... but there are some mistakes,
    1° The evaporator is the upper vessel, you can see the suction pipe to the compressor coming out of the evaporator which is the upper vessel. When you explain the cooling tower, you may say you cool down the water by blowing air through it, it's correct but far from complete, you have to say that you cool down the water because a portion of this water is evaporating; it means the water temperature can reach the air wet bulb temperature.

    Regardless with the CDWS and CDWR if we say CDWS means the Condensing water supply that will RETURN to the Cooling tower going to the hot basin and drop to the cold basin and supply to condenser which is also called cooling tower water supply which is the Condensing water Return, i guess your Condensing water pump must be place in Cooling tower water supply "CDWR"
