I went yesterday to the exhibition Climate World - 2019. I see what's new and interesting for domestic ventilation. A lot of things came.


Perhaps the most interesting thing is that I met there - cheap ventilation system with heat recovery, created by the company Fresh air from Ufa.


The system is not the case - uses standard plastic air ducts and duct fans. The basic idea - long (74 cm) of aluminum heat exchanger tubes are inserted into the duct.


Outside the tubing is passed from the room air outside, the heating tube. Through the tube goes outside air into the room, warm from the tubes. It is alleged that the recovery efficiency of 87%.
In teplobmennike duct 154 60x204 mm tube with wall thickness of 0.2 mm.


Such heat exchangers are produced for different types of ducts.


Since ducts are sold in any hardware store, you can buy not the system as a whole, but only the heat exchanger. it costs 5950 rubles (heat exchanger area of ​​1,342 m²) for 60x204 mm air duct 55x110 mm - 9550 rubles (2,552 m²).

If we consider the ventilation system as a whole, its enormous advantages - recovery and low price. Cons - noise and primitive air filtration.

The second interesting thing discovered in the exhibition - a new ventilator Brezza.


It is similar in design to the Tion and Ballu Air Master. Air is drawn from the bottom, passes through three filters, a heater and a fan. It is possible to take air from the room to filter.


Is blown out at the top. The manufacturer claims that although the fan and is located directly in front of the bars blowing, low noise through the use of high-quality fan.


The main "chip" of the ventilator - a very slim body (13.5 cm).


The ventilator will be available in May. Pre-announced price of 26,000 rubles. It seems that there was a serious competitor Tion and Ballou.

By the way, tion has finally released for sale at the price of 19,990 rubles small breather Lite, An announcement which I I wrote years ago.


In the comments to my every review ventilators someone will write "why so expensive? box fan, filter and heater should cost no more than 10,000 rubles! "and complain that does not appear cheap Chinese counterparts. The exhibition was seen by Chinese ventilator Nilan iFresh-150.


He has a CO2 sensor, PM2.5 and VOC. You know how much it costs? 530 dollars! Not less ours.


Russian company Miniboks released another ventilator called Airnanny (Aeronyanya).


The ventilator integrated ultrasonic humidifier. A strange decision - with the flow of air does not cost much more to make quality and safe natural moisturizing.


Air is blown through the two gratings, such as small as that Tion 3S or less.


Three ventilator modification cost from 41900 to 54900 rubles. With such prices to compete with Tion, Ballu, iFresh and new Brezza it will not be easy.

If you think that this is the most expensive ventilator, look at the German Zehnder. It costs 1800 euros! It differs from all others by the presence of heat recovery.


Reverse recovery system Marley known for a long time: 180 mm hole placed in the wall of the ceramic heat exchanger and fan drives the air from 70 seconds room outside, heating heat exchanger, and then 70 seconds with the preview in a room, while outdoor air is heated by heat exchanger.


The big problem of such a system is taken from the air blowing into the street. If all windows and vents closed and air will inevitably be sucked from obschedomovoy ventilation with all the smells from neighbors.

In Novosibirsk, we created a ventilation system with a reverse recovery Vakio.


Its heat exchanger and a fan mounted in the duct of 125 mm and can be mounted on the valve seat KIV.


Fan physically separate motor turns over every forty seconds. To ensure sufficient ventilation fan is applied at a speed of 10,000 revolutions per minute and the entire indoor unit is essentially a silencer. The filter should one class F6. It is worth such a system is 15 900 rubles.

I do not know how much that ventilation is effective and, most importantly, low noise. Pre-arranged to take her to the test, we'll see.

Domestic ventilation units to the placement on the outer wall of the house is still very expensive. VentMachine Satellite costs from 102 000 to 132 000 rubles.


VentBoks-300 from 90 000 rubles.


In fact, my plywood makeshift home ventilation systemThat cost me less than 5000 rubles, can be considered an analogue of these systems, as well as Zaporozhets can be considered analogous to the Mercedes. :) I use cheap industrial fan, there should ebmpapst, worth 20 thousand. I drive the speed of the fan using Latro hand, there EC fan with a control input, beautiful color control panel with touchscreen and control with smartofna, I have a box of plywood, from there steel. I have a cheap car cabin filters, there are specialized. I do not have a heater (however, the price - 600 rubles from any type of heater Chinese Breeze), there is a ceramic with automatic electronic control. I as a damper is now a rag, there elektrozaslonkoy control processor. :)

The exhibition will run until March 7, 2019. If you want, go look at it all with my own eyes.

P.S. I apologize for the quality of the photos: forgot to wipe the lens of the smartphone, the consequences can see for yourself.
