These are the characteristics of an ultrasonic fogger at less than 10 € ...

Material: Aluminum alloy.
Nebulizer head: a head.
Nebulizer slices: 20 parts (included).
Output capacity: 400 ml / h.
Operating voltage: 24 V DC.
Best position of immersion in water: 5 cm.
Product dimensions:
Diameter: 4,6 cm.
Width: 4 cm.
Cable length: 1,3 m.

USA power adapter (with EU adapter).
Power supply: 100-240 V AC 50 / 60 Hz.
Output: 24 V DC, 1 A.


0,4 L / h Evaporation = 400 / 3600 * 2450 = 270 Watts ...
For 24W consumed (max). We therefore remain in the same order of magnitude of COP ...

Add a PC windillo 10W-15W ... (which is not bad) where to simply make a tank glued to a classic fan ...

The greatest technical difficulty will be to maintain the optimum level of immersion water.

Otherwise there are "high" end fans (= 100 to 350 € so the price of a real air conditioning ... if you look carefully) which offer an integrated misting system ... with reserves of several liters ...

A model with 350 € has its characteristics:

Refurbishes an area of ​​50m² of more than 10 ° c
Autonomy up to 5h thanks to its 10L tank
3 speeds and mist flow control
Watt: 100 Watts


If we consider all these figures as real (not on) ... So we have a cooling capacity of evaporation of:

2 L / h Evaporation = 2000 / 3600 * 2450 = 1350 Watts ...
For 100W consumed (max). We therefore remain in the same order of magnitude of COP ... : Mrgreen:

But 350 € is the price of the first real mobile air conditioning (and reversible in winter ... just fuck outside! : Cheesy: ) ... then the purchase argument is only for savings in use ... so personally I will abstain from putting 350 € in a fogging fan ...

One of the smallest model I've seen consumes in the 800W for cold 2,1 kW ...

The portable air conditioner that refreshes up to 2,1 kW in class A while ensuring minimal impact on the environment. Move it where you want or lend it to whoever you want thanks to its compact design: 35cm width on only 70cm height.

Rated cooling capacity: 2,1 kW *
Cooling capacity: 8.000 BTU / h **
Energy efficiency class: A *
Nominal Energy Efficiency Coefficient: EER 2,7 *
Dehumidification capacity: 1,8 l / hour ***
Refrigerant gas R290 load 0,13 kg
Min-max sound pressure level dB (A) 47-52 ****
Sound power level dB (A) 63 *****
Flexible hose for evacuation outside hot air 1500 mm * 150 Ø
No tank: automatic condensate removal
Multifunction remote control
LCD screen
Programming possible up to 12h
Practical side handles
Window kit supplied
Casters

* Test conditions: data refer to EN14511 standard
** 35 ° C / 80% UR
*** 30 / 27,1 ° C (DB / WB) in dehumidification mode
**** Test data declaration in semi anechoic chamber at 2 m distance
***** EN12102


ps: pardon is more to say COP in case of fridge machine but EER ...

You write:
The greatest technical difficulty will be to maintain the optimum level of immersion water.

It is easy to install a reserve with the pipe that plunges into the nebulizer tank and, by siphoning (such as water troughs), continuously adjusts the water level, after trial and error adjustment ...
Otherwise, for those who would like a more ambitious installation ... and for cheap (there you really load!), Here is what I had done: a small pump for a drinks vending machine *, a "pressure" pvc ramp **, glue-in tees and oil burner jets *** ... Cheaper, you die! And efficiency question, just a bit less efficient (there are a few micro drops which do not generally interfere with anything) than the American system from which I was inspired by outrageously simplifying and which cost the skin of the buttocks ...

* Recovery...
** It's thicker than the exhaust pipe, but it's so easy to tease.
*** The drink dispenser pump and the burner pump both work at 10 bars: it was when I learned this correspondence that it tilted in my little head! : Idea:

Butter and butter money :?:

It is 2250 j / g the latent heat of vaporization at atmospheric pressure, 1250 Wh for 2 l and not watts.

This energy is not drawn from anywhere but from the ambient air. : Mrgreen:

Since the specific heat capacity of the air is 1004 J / kg / K, it is necessary to cool 1494 kg (1156 m3) with 3 ° C air to obtain the necessary energy, otherwise very quickly it will stop as soon as the hygrometry will exceed 60% (in a room 40 m3) ... Otherwise will open the windows in large and let in the warm air outside : Twisted:

Except that this value depends on the temperature ALSO ...

At 100 ° C it is 2250 j / g ... at 20 ° C it goes up to 2450 j / g, you still want to give me lessons? One more proof that you do not really know the subject... but I think that we will definitely not agree in this discussion, I leave you in your thermodynamic mistakes ... with your personal judgments that go with : Evil:

https://energieplus-lesite.be/theories/ ... r-latente/

Note that the heat of vaporization varies according to the temperature of the water that evaporates: 2 257 kJ / kg at 100 ° C, the heat of vaporization is 2 454 kJ / kg at 20 ° C and 2 501 kJ / kg at 0 ° C. It is therefore a little easier for a droplet to go into the vapor state when it is already at 100 ° C.

Of course if he is there phd.

But hey, it's a bit complicated with a guy like you. Because of course, you own Truth. The leader speaks and all the airs applauds. Well no. Sorry

On the other hand, as far as I am concerned, I will remain courteous, to change.

So let's pick up point by point in this jumble.

you make everyone laugh with this comparison since you visibly confuse humidity contained in the air and water vapor ...


I will not answer but just give a link, I suppose still some horns
http://www.meteofrance.fr/prevoir-le-te ... s/humidite

Do you understand the absurdity of your comparison between these 2 dew points if the humidity of the air condensed from 47 ° C ... all interior walls of houses, colder than 47 ° C, would be constantly under the dew point and therefore dripping condensation!


There is no absurdity because I did not speak the same things. In the first post, I mentioned the air treatment with the different reactions of the humidity naturally present in the air in the form of steam according to its situation, the relative humidity of an air representing the weight of vapor content based on a%, the 100% representing the saturation weight.
While in the second, I answered a question about condensation in boilers where the situation is completely different since in this case, a large amount of steam linked to combustion has been added and therefore has nothing to do with the first case.

The only case where there is condensation of water vapor in a house is when you boil water in the kitchen ... because there is water vapor that condenses! And when taking a shower, the mirror (and any other surface) can condense moisture from the air because the air gains a lot of moisture without the surfaces having time to warm up enough and can even become saturated (fog) in the case of long hot showers ...


So there for once, I think that precisely, do not show this to a specialist. I only know 3 water conditions: vapor, liquid and solid. The humidity state does not exist.
Moreover to take your two examples that are of course speaking, it is not the fact of boiling water that systematically condenses but boiling adding a weight of water to the air will increase d as much as the corresponding dew point. This is also the same phenomenon for the shower but for you it is no longer steam.

you still want to give me lessons? One more proof that you do not really know the subject ... but I think that we will definitely not agree in this discussion, I leave you in your thermodynamic mistakes ... with your personal judgments that go with


And frankly, it's the pompom. The chef is right and knows absolutely everything about the air and its treatment. Would not it be a little oversized ego? I understand that you have some knowledge of the subject of water injection into the engines, although the term is a bit inappropriate. This is a very specific and probably very interesting topic but it does not allow you to pretend that you know everything in these very specific areas.

The same is true between the combustion of a fuel in a boiler and in an engine, even if there are common points, they are two very different applications and the specialists of one are not the specialists of the other.

I do not even hope to convince you, but what I'm sure of is that you can learn at any age, yet you have to admit it.

Sincerely, phd

Ok, you must be right for that, I trusted this chart https://www.thermexcel.com/french/tables/vap_eau.htm, or for example, line 2, 24.1 ° no longer corresponds to 1 bar, but 0.03?

On the other hand, it means that to evaporate 2 l of water, it is necessary to cool with more volume of air than the 1156 m3 previously calculated.

What does phd think?

Absolutely, he is perfectly right. It also depends on atmospheric pressure, weather and altitude fluctuations will change the game.

So in practice, we take average values ​​to make sure that it works in all cases of weather changes. And for altitude, we must review the parameters, all!
the link below will give you some indications.

I was answering izentrop who did not miss me to make personal peaks, confused condensation of boiler and ambient air and displayed his bad faith ... without recognizing it ...

In short ... why take for you the answer (s) I made him?

The last measurements I made confirmed that we have 100W evaporation power ... for 7,5W consumed ... which validates the concept. So what? And strangely none of you 2 has reacted on these measures ...

Obviously the cold power remains limited (I never claimed the opposite: except that my 1ere measure was increased because based on optimistic measures and manufacturer figures not necessarily realistic .... So I say so much better if thanks to you I made a measurement more precise and realistic!).

In short in direct cooling is better than a fan 50W ...

We still need to go around in circles?

I admit that I went looking for calculations more complicated than you on this humid air fan that is akin to a mini fogger.
Since it is a wet sponge that is dried by forced ventilation, its calculations are quite appropriate:
Drying clothes at room temperature

You must be among the most satisfied apparently:

So here, for once, I will take the defense of our tester, because I do not think we can question his seriousness. And for the result, I validate. And you will notice that the results given are in W, so that everyone understands.

I liked the article on drying clothes. I still hope that the author did not file a copyright : Cheesy: .

And what is this disease to use joules. This may be the ISO standard. Nobody in the profession uses it. It's true that it allows you to fart a little. The guy is going to buy a boiler of 82800 joules. It's even more fun for the strong power. As a central air 1.62e9 joules.

As for opinions on amazon or others, no one can rely on it, especially in a field like this.

So today, this morning, in my home, I recorded 23 ° C and 72% of HR. Stormy weather, what. The device still works ?? And in my basement, the soil is wet with puddles in places. I disconnected my thermodynamic water heater from his pipes to make him breathe in the basement air. He condenses a max and it is not enough yet.
