Summer is in full swing right now. And it is in this sultry and hot time that each of us is looking for coolness, which is so necessary for us for comfort. And even though everything is simpler in the country - the good old air conditioner comes to the rescue - but on the site we have nowhere to look for salvation. So what to do? There is one rather original method, which I would like to talk about in today's article. But let's not get ahead of ourselves.
Fog on ... summer cottage!
There are so-called fogging systems that can not only create a vivid and unforgettable visual effect, but also significantly lower the temperature by. What is the principle of operation of such a system? It is extremely simple: water is sprayed through special nozzles at very high pressure (about seventy bar).
Fogging systems can be of two types - mobile and stationary. Mobile devices are characterized by the fact that the compressor in them, the nozzles and the pipeline are located in one module.
Functions of misting systems
Fogging systems perform several functions simultaneously. So, here's how artificial fog will help us in our summer cottage:
1. It creates an impressive visual effect.
2. Significantly cools the air.
3. Eliminates almost all odors present.
4. Adsorbs dust (which is very beneficial for our health).
A light evening fog that will smoothly spread over your site will not only make it really original, but will also cause the neighbors and passers-by to envy. Moreover, I recommend that you use fog in the event that the site already has a pool or any other body of water - it will be even more effective!
Fields of use of foggers
Artificial fog systems can also be used in the following areas:
1. On the summer terraces of cafes or restaurants. Such a simple trick will really attract even more customers. What do you think, in what environment is it better to spend time with friends or with family: under the scorching sun or in an atmosphere of coolness and comfort?
2. Artificial fog can also be used in industry, especially when overheating of some elements of the system is unacceptable. For example, enterprises with increased dustiness, oil refineries and so on.
3. Finally, in recreation and sports. Foggers can be used on tennis courts, parks, golf courses, stages and more.
In our country, systems for the formation of artificial fog are still not widespread. They are mainly used to create a special atmosphere in water parks, to cool outdoor summer cafes. But such fogging systems have a much wider scope. Let's take a look at their features.
Of course, today modern split systems are used to cool the premises, which do their job perfectly. But sitting indoors all summer is a shame and simply impossible. Foggers will help you escape from the heat on the street, which, even at a temperature of +45 degrees, can make staying in the heat much more comfortable.
Advanced gardeners install fog systems in greenhouses to create optimal conditions for a rich harvest. Sometimes such a system becomes an addition to drip or automatic irrigation. However, the fogger can be installed, for example, on a terrace, veranda, roof of an open gazebo, just near the pool of a country house.
A fairly simple fogger is a fan with water supply through nozzles. However, a more efficient fogging system designed for large areas is a pump and pipes with nozzles that produce tiny water droplets - this is artificial fog. Ideal working conditions for such a system are temperatures from +29 to +45 degrees and humidity from 40% to 80%. Under such conditions, the fogger can reduce the temperature in the area by 10 or even 15 degrees. Humidity will, of course, increase, but not so much that you become uncomfortable.
Fogging systems are divided into two types:
- Low pressure. In this case, the resulting water droplets will be quite large - about 100 microns. That is, they will not evaporate in the air, the floor and walls, for example, verandas, where you decide to install the system, will be wet.
- High pressure - from 50 to 100 bar. In this case, the droplets coming out of the nozzles will be no larger than 1-15 microns in size. Such droplets easily evaporate completely, there will be no wet surfaces.
It is up to you to choose a system, perhaps for areas near plants, the incomplete evaporation of fog drops will even be useful and will allow you to moisten the soil. But for verandas with garden furniture, it is better to choose a high-pressure fogging system.
The advantage of the artificial fog formation system is the ability to use it in any space. You can install just four nozzles at the corners of the gazebo to create a curtain of fog, you can surround the pool or large terrace with the system. In addition, such a fog curtain, installed around the perimeter of a certain area or structure, will perfectly repel insects, keep dust and hot dry air as a barrier. Inside the perimeter, a comfortable atmosphere will be created for relaxing on the site in the summer, the plants will also feel great.
But the fogging system also has enough minuses. One of them, quite significant - the high price. The cost of a fogging system can exceed 55 thousand rubles, and installation in case of contacting professionals - 5 thousand rubles per square meter. Installing a fogging system yourself is difficult, you need the right approach to design and installation in order for everything to work perfectly.
Another disadvantage is the consumption of water and electricity. Of course, the costs are small if a modern energy-saving system is chosen, but they are there.
Whether to buy a fogger is, of course, up to you. It seems that such an option for cooling certain areas of a summer house or a country estate deserves your attention in any case.
Happy first day of summer everyone! Although the summer is rainy, I believe the heat will come, so the review is dedicated to hot weather - you need to prepare for it in advance!
Walking around the city in the summer, I repeatedly met “fog” sprayers suspended at the top, usually made using special high-pressure pumps. I live in a rather hot climate, it is quite natural that I have been “drooling” on this device for a long time, but the price stopped me.
An evening visit to the dinosaur park added fuel to the fire ... the illuminated fog among the thickets and tall trees, and the dinosaurs moving in it looked very impressive ... although I don’t seem to be bloodthirsty by nature, I caught myself thinking that it even gave me some pleasure;).
Well, since I almost constantly live in the country, and I like to be on the open veranda on summer evenings, I decided to look for something similar on Ali (of course, I meant not dinosaurs for my mother-in-law;).
Quite a lot of "rummaged through" the options ... First, I discarded the options with pumps, as they were completely unbudgetary and at the same time did not give a guarantee of obtaining the desired effect.
Then I removed the options with plastic nozzles and nozzles with a large hole diameter, with beautiful advertising (which I didn’t really believe). I wanted to get a dispersion most similar to fog, and not an “irrigation” system “on my own head” in the truest sense of the word.
As a result, there are very few options left.
Among them, there was a seller with a rather high rating of 98.8%, who, moreover, agreed to make some discount on his product - he could not resist. I decided to try "in action" :) And already in the spring I made an order.
Screenshot of the order
By agreement with the seller, it was sent (to reduce the cost) by simple mail - but I wasn’t in any particular hurry, I was supposed to use it anyway due to hot weather ... and the spring somehow “failed”, and so it constantly drips from above.
Arrived in a "sovdepovskaya" cardboard box
On the page there is such an advertisement for this “device” in action, not to say that I particularly trust this kind of photographs exhibited for any product (including those with pumps), but I wanted to get something at least remotely similar.
The store claims the following specifications and scope of delivery:
>one set includes:
A. Adapter 1pc
B. Quick connector adapter 1pc
C. Slip lock connector - 10 pcs.
D. Mist nozzle - 10 pcs.
E. Tubes 15 m
F. Plug - 1 pc.
G. Clip 10 pcs.
Understand which of them decided later ...
The seller also promised:
* Quick installation, simple and flexible, energy saving.
* Even after installation, the side of the tube can be changed freely.
* Special design of slip lock connector to make it more convenient and labor-saving to unplug.
* Kits include stainless steel clamps (clip). It is easy for them to be installed in narrow places and walls.
* DIY systems
Let's translate all this into a language we understand!
Doing so as we were taught from kindergarten Of course it's easier with pictures :)
This is the set I received: 
15 meters of hose (pretty stiff - probably rated for decent pressure) 
adapters for connecting this thin hose to a faucet or irrigation hose. 
Moreover, the adapter even has a mesh filter to prevent large particles from entering the atomizer system 
Clamps for fastening the hose in rubber, probably to prevent chafing of the hose by the side edges, well, for a more secure fit 
10 pieces, I don’t know what to call them - the “crap” that connects the pieces of the hose and into which the nozzle is screwed. A kind of connector with a thread for a sprayer. 
By the way, looking ahead, I will say that I VERY liked this “crap” - this connector is very cleverly made. It has holes for the hose on both sides, so these holes are quick couplings. 
Those. in the manner of garden irrigation systems - when squeezing the rings (there are on each side), the clamps converge / diverge inside, which fix the hose very firmly and hermetically. Once connected, the hose can be easily rotated, or quickly dismantled for reconfiguration of the entire system, or for storage. Credit to the manufacturer!
Well, further to our kit ... the most important detail is 10 pieces of injectors 
which have a declared diameter of 0.3mm and which should give out 10-30 micron drops (I wonder how they can be measured? :) 
on the reverse side of each nozzle there is a rubber sealing ring 
Well, probably the last “important” detail of this “LEGO” is the plug at the end of the hose. 
This is how the “piece” of the assembled connector with the nozzle looks like 
To begin with, I decided to see, “was it worth it”? And before assembling the whole structure, I assembled the system for one nozzle using the entire cable (then I was tormented to drive water out of it - there was a puddle :) 
connected it in the garden to a standard watering system 
well, I actually turned it on ... to be honest, the result was somehow not particularly impressive: (something, of course, splashed, but not quite what I wanted to see ... 
it seemed somehow not too fine dispersion turns out ... okay, let's go. We need to see what happens when connecting a large number of nozzles - how much the spray will change and how it will look. One nozzle does not give a normal performance.
Well - we take the tool and proceed to the test assembly?
You will need a tape measure and a knife itself. 
We estimate at what distance and how many nozzles we want to place and cut the hose into pieces of the required length, since it has a margin. I proceeded from about 4 meters of the length of my veranda and 10 nozzles, so I cut about 9 identical pieces + one longer inlet - to connect to the water. 
We equip all connectors with nozzles 
by the way, this is what the clamp looks like - it sits quite tightly even without compression. 
well, voila - the assembled system ... It all took ... and hell knows how much, I forgot to detect the time! Pretty fast and easy! 
Naturally, I immediately went to try it!
… what can I say!? And it works… and even quite decently! Photos do not show the size of the dispersion well, only in general. 
At some angle, a rather contrasting rainbow is visible, which shows the presence of a large number of rather small particles. 
Since the use of this irrigation system is not only cooling "resting places", but can also be used to create a very humid environment, for example, in a greenhouse (the seller also offers the option of air purification and dust precipitation in a similar way indoors), here is a photo of how it can be used in a greenhouse 
As we can see, everything looks pretty decent. Of course, questions remain, how quickly it can clog, etc. Although, in part, I took exactly this kind of nozzles, with the possibility of their subsequent cleaning (if necessary).
A short video of work in the greenhouse ...
Well, it's time to "try on" on the veranda? :)
There was still no weather to cool off ... I waited a lot of days. Some kind of spring ... damp and cool and without additional moisture (I noticed this more than once - you install a split - the summer is cold, you buy a cool stove-fireplace, winter is frost-free). Tired of waiting decided to try the "cold".
Attached to the top of the veranda with self-tapping screws ...
there was a garland from the winter nearby, but in principle it is protected from precipitation.
What can I say ... the first pancake was lumpy ... while I was running I turned on the "sprayer" I realized that I needed to run even faster to turn it off :)))) 
Somehow I did not calculate the position of the nozzles clearly. Everything around is wet and, interestingly, the nozzles continue to water for quite some time after the tap is closed. Probably a little residual pressure in the hose is enough. After a couple of minutes of waiting, I had to turn off the hose - the water consumption is small, you can wait a long time otherwise.
I outweighed it with a margin and placed the nozzles a little differently, checked it - IN! Practically what is needed, except that it seems that there are “not enough” injectors, although who knows - you need to test it for a longer time and in fact determine it already :)
Looks EXACTLY like this! Approximately, because the photo conveys all this suspension / fog very poorly. 
View from afar of the place of rest, the fog itself, of course, is not particularly visible :( 
Therefore, a few fragments of the video - the atmosphere is somewhat clearer there ... and yes, everything is dry now :)
In short, so far I am satisfied with the purchase ... Time will tell how comfortable it will be in the heat - until the weather is hot and stuffy enough outside to give an unambiguous answer - will there be any use other than external “decoration” with fog. But you need to post a review now if you want to be in time with the purchase before the heat sets in;)
You need to understand that the dispersion of particles of this "sprayer" is approximately equal to any kind of spray in cans, and larger than that obtained, for example, by ultrasound or nozzles under significant pressure, but for "its" purposes it is very good, even better than expected. Those. not a fog in the full sense of the word, but a very fine mist...
Pluses quick and easy assembly / disassembly, and repeated is allowed! Good spray quality without the use of special pumps - just from the tap. Very low water consumption.
Minus, well, just the price, perhaps, it could still be cheaper ... The rest of the minuses will probably appear over time - I haven’t found it yet.
ZYZH I recommend the seller - sociable and decent in appearance, you can "beg" for a discount;) And the price list for this particular type of kit is perhaps the cheapest, cheaper with similar nozzles and mounts could not be found - I was looking for a long time.

artificial fog
artificial fog obtained using special spraying installations equipped with nozzles that spray water jets. The installation of the GBS of the Academy of Sciences of the Russian Federation gives a finer spray (146 - 360 microns), identical to fog, and can work continuously and intermittently (20 s on, 1 min break). The TSCA installation gives larger drops, works intermittently - after 15 - 20 minutes it turns on for 1 - 2 minutes - and is widely used in practice when rooting cuttings on ridges. The creation of artificial fog installations made it possible to promote green cuttings in arid regions (Crimea, the Volga region), where before it was not used at all.
When using artificial fog on a TSCA plant, rooting of cuttings is carried out on open ground ridges, but under a film cover.
The best film cover is on a permanent frame of a block greenhouse, where the spraying devices are placed permanently. The film on the greenhouse is stretched annually.
Rooting in greenhouses can be carried out with electric heating of the substrate. Electric heating allows you to extend the terms of grafting in the middle zone and carry out the rooting of 2-4 batches of cuttings during the growing season (2-4 rotations).
Important in green cuttings is the substrate in which the rooting of the cuttings takes place. The substrate must provide the optimal ratio of moisture and air in the root formation zone and be sterile. Until recently, the classic substrate for all breeds was fine-grained river sand, which was washed and calcined before planting the cuttings. But different breeds, other things being equal, took root in it differently. Modern agricultural technology has at its disposal various substrates, which are used differentially for breeds.
Currently, expanded clay, perlite, vermiculite, their mixtures - perlite with sand (1: 1), vermiculite with peat (1: 1), ion-exchange substrates are also used as substrates for rooting cuttings. Any substrate must have good water-holding capacity, aeration, thermal conditions and specific acidity for each species.
Vermiculite is an aluminum-magnesium-iron silicate in the form of mica plates, perlite is a free-flowing large-pore white material from volcanic acid rocks. Both substrates are obtained from natural materials by firing the latter in special furnaces at a temperature of 800-1300 ° C; have a volumetric weight 8 -8.5 times less (0.17 - 0.20 g / cm 3), and a moisture capacity 35 -40 times greater than sand; chemically inert; sterile - do not contain an infecting principle, like sand and peat, so the plants on them are not affected by diseases.
Expanded clay is a granule with a diameter of 2 to 50 mm, obtained by firing shale, loam and clay with organic fillers. For green cuttings, fractions of 3-5 mm are used.
With any technology of rooting green cuttings - in greenhouses, hotbeds, in open ground under temporary film cover, using a fogging installation or manual spraying, with different substrates for rooting cuttings - the place for planting the cuttings is prepared carefully. The surface of the greenhouse, the ridges are carefully shoveled and leveled. A layer of fertile disinfected substrate about 15 cm thick is poured onto this surface or a flat surface of the rack, which is also carefully leveled. A layer of rooting substrate 4-5 cm thick is poured onto this fertile layer, into which the basal part of the cutting is immersed to a depth of 0.5-1 cm so that the cut in no case touches the fertile layer. The fertile layer is needed so that the formed roots gradually move from the rooting substrate to the fertile soil and are able to actively supply the aerial part of the cutting with metabolites. Places for planting cuttings are marked with a marker.
Hydroponics can also be used to root cuttings. In this case, special containers in the form of a rectangular trough are filled with a low-moisture-intensive substrate - gravel, expanded clay, ion-exchange substrate, coarse sand. On top of this main substrate, a layer of substrate for rooting is poured 2-5 cm thick - a mixture of fine-grained sand with peat. After planting the cuttings, the container is filled from below with water to the level of a mixture of sand and peat; with the beginning of rooting (callus formation or the appearance of roots on the internodes), the water is replaced with a nutrient solution and the supply level is reduced by 2 cm. The composition of the solution in hydroponics is different, but should contain both macro- and microelements. The use of solutions ensures the best development of the resulting roots. With the hydroponic method, it is not necessary to spray the cuttings, since optimal air humidity is created under the film. During the rooting period, the cuttings must be cared for - choose fallen leaves, dead cuttings, destroy weeds.
Of considerable interest for practical use is aeroponics - the rooting of cuttings in the air. Rooting cuttings without soil and substrate (rooting layer) is economically beneficial.
With the aeroponic method of rooting, the bases of the cuttings are in space, periodically saturated with a solution containing the necessary elements through a spray device. At the same time, the lower part of the cuttings is also sprayed with this solution.
