How cooling towers works

Hi friends,In this Article we're gonna check out the operation of a cooling system . 

  cooling tower diagram 

         So even as a fast overview of what to expect from this text we're gonna check out the operation of the cooling system here And we're gonna check out how the nice and cozy water, which is being sent from the chiller and contains the warmth from the building, which must be rejected.

    (cooling tower basics)That's getting to enter the header undergo this spray nozzle and be distributed over this packaging. That warm water will then loose a number of it's heat because it makes it's thanks to rock bottom here. it'll drip down and then collect into the basin and therefore the cooler condenser water is then collected from the basin sent backtrack to the chiller, where it'll devour that heat again and be sent up during a continuous loop there. cooling tower definition

 

 cooling tower basics  

    cooling tower power plant ,which humid air, you know it's lost some humidity here; that's then rejected by this fan and pushed out into the atmosphere. We're gonna check out each part of this in far more detail, Cooler towers, but these are really used on every single building, large building. Just the sort of cooling tower will change.      Some are going to be kind of open wet cooling towers and a few won't. It all depends on the planning criteria. we have got a touch model of a cooling system. during a world example of one among these sorts of cooling towers. We're gonna run through how one among these works and what it's used for. So in building services these are used on almost every single office block round the world counting on it's size. 
         (cooling tower diagram) Meanwhile cooler air /ambient air is being sucked in to the present cooling system . That passes within the opposite direction of the condenser water which picks up the warmth from the water. But because it does that it'll also devour a number of the water making this very humid and really moist. So we have got this drift eliminator at the highest here which will condense a number of that water so we will reclaim it and keep our operating expense down. 

       induced draft cooling tower   They're very effective at rejecting heat. So what happens is; you employ these to reject the warmth from the building. So all the warmth gets picked up from people, computers, machines,lighting, all the solar gain, all of that heat needs to be faraway from the building to stay it cool. So that's picked up by a chiller and it's sent from the condenser up into ones of those , which may be a cooling system . and therefore the purpose of this plant item here is to require water in at a particular temperature and put it back to the building at a way lower temperature in order that it can devour more heat again and send it back to be chucked out of the unit.

       So let's have check out some of the components in there. you will see on the highest we have got a lover . So this fan obviously spins and because it does so it pulls air out of the unit. Air flows in, fresh air, ambient air, air around you flows in from the panels, which it just filters. they have an inlet shield just to prevent sunlight and mud and bugs, maybe animals, even children getting into there. (laughing) therefore the air comes into now here then makes it's way up and gets pulled out of the cooling system at the highest here. And on the surface we have got a motor here And on this instance I've just made an easy belt drive system which pulls that fan. 

     application of cooling tower  But the motor might be mounted inside or it might be a gear ratio or something. But we're just keeping it very simple on this one, so I've put a belt system on there and truly let's have a look inside the unit here. So, this is often a peek inside the unit. And as you'll see we've got some pipes here with some funny looking plastic parts here and here. A couple of other little pipes, let's just change view there. So, the condenser water which is that the warm water that's being collected from the building and being sent up by the chiller, that enters through this pipe and it enters into the header which warm water is then sprayed out of those spray nozzles. 

     cooling tower , Within the world the spray nozzles coming down onto the packaging will look a touch. So these nozzles here quite this and they are just spraying down across the fill packaging. On to the present which is understood as the packaging or the fill. within the world the packaging will look something and therefore the purpose of this fill is that the water, the condenser water will run because it sprays in really fine particles and it collects and runs down the sides of this during a thin film. 

      Now the air which is rushing past the opposite way picks up heat from this because if you let it just quite run out then it's got a little area , but if you spread it out and convey the really thin film, across of these packaging sheets, which is formed of a kind of plastic then that increases the area . then you're maximizing the world that the air can reach or can touch. then once it does that it pulls the warmth out of that water. The water, the condenser water will then avalanche the side here and drip down and collect down here within the basin. 

     which warm air will enter through the sides or these panels, make it'sway up through these grills or the fill packaging,past this pipe work, up out through the drift eliminators, then out through the highest . As that water pours out of the pipe work and it sprays and becomes a skinny film along this fill packaging here what we're gonna find is that a number of the water will evaporate, which takes a number of the warmth away. But we're gonna lose moisture thereto also .

         Therefore the purpose of this which is called the fill packaging. No it isn't sorry it's called the drift eliminator. What happens is that the air enters into here, it's being pulled by the fan at the highest here and therefore the air is coming in at a high velocity and it's impacting, it'shitting against the surfaces. It's gonna make these really sharp turns to urge out of the system and obtain to where the fan is trying to pull it out through. So because it does this and it's colliding with the edges and that is giving the moisture within the air an opportunity to condense on the sides then run down.

       Therefore the more impact it makes the more it's condensing that vapor within the air and allowing it to condense and pour away. So we'll reclaim a number of that water, which might otherwise have lost and be sent bent the atmosphere. Down within the basin here we have got variety of pipes. We'll  the most important pipe here. It's a few six inch pipe and that's the outlet. So this is often the condenser water return, which is gonna go back down into the building and right down to the condenser of the chiller. up here we have got the water inlet which is connected to a valve . So because the water level gets too low this may allow more water to enter the tower. And keep this filled to a particular level. 

          Here we have got the over flow. So say this was to possess got stuck, something like the water would pour in here to fill it up, but there is no where for that to travel and you do not want it to refill and begin browsing the tower out the edges here. So we have got an overflow here. Just to require a number of that flow off . 

         The last part here we've got is that the drain. therefore the drain is sort of important because within the water that's entering this tower here, the water contains salts and bacteria and stuff like that and as this water evaporates it's gonna leave behind that salt and therefore the gunk and muck that's contained within the water. which salt won't evaporate. which will start to collect up here within the basin or abreast of the fill packaging etc. then once it reaches a particular level this may got to drain, therefore the cooling system are going to be told to dump tons of the water that's during this tower right down to drain while they add water . Not through that one,sorry through this one. They add water to the system in through here or through the condenser water inlet there. And once that has reached a particular amount of parts per million the minimum threshold, that drain will close and it'll continue init's cycle of operation. and that is really it for a cooling system . Well for this sort of induced draft open cooling system .
