00:00:01

and making improvements to it,

00:00:03

it’s time to share the

00:00:05

test results with you, but first

00:00:07

I’ll tell you why a recuperator is needed. In

00:00:09

principle, the essence of its work is removed from the

00:00:11

room from work to the air to the street

00:00:12

through a heat exchanger, at the same time you heat

00:00:14

the flames and clean water is already supplied to the house

00:00:17

heated air from the streets, that is, do not

00:00:19

cool down the house with clean air, in the

00:00:21

comments they wrote what the problem is;

00:00:23

open the window, here’s the air,

00:00:24

but you won’t keep the window open all the time,

00:00:26

and indoors with a closed

00:00:28

window, the air is quite quickly saturated with

00:00:30

carbon dioxide,

00:00:31

which has a very detrimental effect on health,

00:00:33

here you go a simple example is a room of 17 meters

00:00:36

and three people are sitting in it talking

00:00:38

and this is the co2 level and it rises 600

00:00:41

units to a critical one and a half thousand in

00:00:44

three hours, in addition to it the concentration of

00:00:45

formaldehyde and other harmful impurities increases,

00:00:48

that is, when you sleep the

00:00:50

same thing happens and it happens that it hurts in the morning head

00:00:52

but there is no bad sleep from the high

00:00:54

co2 content

00:00:55

you can sleep with an open window but in

00:00:57

winter it can be quite cool

00:00:59

and the air on the street is always clean or

00:01:01

sued unpleasant

00:01:03

odors allergens other evil spirits can get into the house also

00:01:06

air filters would be useful but that will

00:01:08

start with this model later and I

00:01:10

designed a specially short one so

00:01:12

that it could be installed in this

00:01:13

wall; making this model without a 3D

00:01:16

printer is quite problematic; not

00:01:18

everyone has a 3D printer, and ordering parts on the side

00:01:20

costs, as I read in the

00:01:22

comments, unrealistically expensive, but I’ll tell you

00:01:24

straight, it’s not very effective as a recuperator

00:01:26

from -due to the small area of aluminum plates

00:01:28

inside, its efficiency is around 30 percent

00:01:31

for ventilation, the model is well suited

00:01:33

in an apartment with central heating where you do

00:01:35

n’t need to worry too much about

00:01:37

heat conservation, but I’ll still conduct a test with it

00:01:39

to clearly demonstrate its

00:01:41

work in numbers, finally the anemometer arrived

00:01:43

and you can see what kind of air flow the

00:01:45

fans create, the air flow is

00:01:47

around one and a half cubic meters per minute for

00:01:49

blowing out and about the same for blowing in.

00:01:51

In the comments they asked why

00:01:53

I installed this prototype instead of a window,

00:01:54

which I am testing;

00:02:02

air pollution is up to

00:02:04

300 units and I will watch how much

00:02:06

it cleans the room in one hour, he

00:02:08

quite quickly reduced the indicator from 300

00:02:11

to 180

00:02:12

and at this level the cleaning froze. To the

00:02:14

disadvantages of this model, I will add that it

00:02:15

works without air purification filters

00:02:17

in the past video to do with it and it

00:02:19

can handle air pollution in one

00:02:21

hour there was a room of 7 square

00:02:23

meters and this room is 17 square meters

00:02:25

now it’s the turn of a larger model

00:02:28

whose efficiency is higher and the fans are more powerful in the

00:02:30

last video I paid little attention to the

00:02:32

assembly and devices and why there were a lot of

00:02:34

questions about how it works now

00:02:37

I’ll handle it and show you all the process of assembling

00:02:39

those tubes is the heat exchanger of the

00:02:41

recuperator, we put plastic

00:02:43

parts on the ventilation duct on it, so the

00:02:45

duct air comes from the street and passes

00:02:47

inside these aluminum tubes,

00:02:49

it is better to use brass limit to

00:02:51

increase the efficiency of the

00:02:52

heat exchanger, I think the efficiency will increase

00:02:55

by 10-20 percent, but the cost of the

00:02:58

tubes will be about $100

00:02:59

aluminum stories 15 also deal with

00:03:02

the calculation to make it accessible

00:03:03

and through this hole the air leaves the

00:03:06

room to the street, warms the hands

00:03:08

from the outside, passing inside these tubes, the

00:03:10

air from the street flows into the house heated

00:03:12

due to the fact that the tubes are heated by the

00:03:14

flow of warm air leaving the

00:03:16

house; this is the principle of a recuperator, that is,

00:03:19

flows the air inside does not intersect,

00:03:20

then I’ll adopt a fan for the outgoing

00:03:23

air and a second one for the incoming air, a more

00:03:25

powerful one, it is necessary for the air to pass

00:03:27

inside the tubes, there is air resistance, let’s

00:03:29

further explain here the incoming and

00:03:32

outgoing fans are located next to each other,

00:03:34

ideally they need to be separated at a distance of

00:03:35

30-50 centimeters, let’s have a prototype

00:03:38

for for clarity, they are located side by side,

00:03:40

also inside the room, the entrance and exit

00:03:42

need to be separated by the same distance,

00:03:44

now the device is standing in a window for

00:03:46

testing, I

00:03:48

’m installing the final version inside the wall of the house, let’s check

00:03:51

what kind of air flow these

00:03:52

fans create, there is a very large hole, the

00:03:54

flow is almost not felt, so

00:03:56

I cut out such a plug to catch it the

00:03:58

entire flow is about one and a half cubic meters

00:04:00

per minute, both incoming and outgoing,

00:04:03

approximately the same as in the previous model,

00:04:05

although the fans are much more powerful,

00:04:07

but the air resistance is also higher due to

00:04:10

the heat exchanger, and so we proceed to

00:04:12

testing as last time, the incense

00:04:14

stick causes air pollution

00:04:16

with particles smoke up to 300 units and, like the

00:04:19

previous sample, it often cleaned the air from

00:04:21

300 to 170

00:04:22

and I

00:04:24

tried to install them without air filters and the result was

00:04:27

completely disastrous, I need to do something with the

00:04:29

fans since the problem is in them, the

00:04:31

design is very successful in my opinion

00:04:33

and efficiency more than 70 percent found on

00:04:36

aliexpress server fans of the 22nd

00:04:39

radial type came quite

00:04:41

quickly they work, how cool they are, but

00:04:44

there is a minus - this is the noise, I

00:04:45

decided not to bother with the

00:04:47

motor control circuit, but I change the

00:04:49

speed of the current, here it is from 5 to 12 volts,

00:05:04

the air flow is from 7 up to 15 cubic

00:05:07

meters per minute, which is a lot; even at the

00:05:09

lowest speeds, it creates an air

00:05:11

flow that is much larger than the fan that

00:05:13

was in the previous model. So far I decided to

00:05:15

adopt them so that I could check

00:05:17

the efficiency and at the same time installed

00:05:18

the car on a carbon filter,

00:05:19

let’s check what kind of air flow

00:05:21

is created at the minimum

00:05:23

air power the flow due to resistance

00:05:24

decreased to four and a half

00:05:26

cubic meters per minute for blowing in and to three and a

00:05:29

half for blowing out, but this is still a

00:05:30

very decent result.

00:05:37

I can say that

00:05:41

it did an excellent job, purified the air up to

00:05:43

70 units despite the fact that there was a carbon

00:05:46

filter which the previous fans did not

00:05:47

pull,

00:05:48

but there is also a downside: the noise next

00:05:51

to the device is about 60 decibels,

00:05:53

but at a distance of 1 meter the noise is no longer so

00:05:56

strong, 36 decibels despite the fact that the room the

00:05:58

noise level is about 20, I think if

00:06:01

you install it inside the wall that it will be

00:06:03

quite acceptable, but you will need to make

00:06:05

motor control boards so that you

00:06:07

can lower the speed to reduce the noise even

00:06:09

more because such

00:06:11

performance seems to me excessive, in

00:06:13

general I am more than happy with these motors and

00:06:15

will do the final I

00:06:17

also decided to make a breather version with them for the apartment,

00:06:19

the purpose of which will not be to

00:06:21

retain heat, but to

00:06:23

clean the air as much as possible from all possible

00:06:25

allergens, bacteria and other evil spirits. I’m currently

00:06:27

working on testing it and will

00:06:30

soon share the results with you,

00:06:31

thank you for watching
