Ikki yil oldin TED da emlash mahsulotlarini saqlash
00:16
based on some comments that were made
1
4000
3000
ehtiyoji haqida qilingan
00:19
at TED two years ago
2
7000
1000
fikrlarga asoslangan holda
00:20
about the need for the storage of vaccine.

hozirda biz bu ish ustida ishlayapmiz

(Video) Narrator: On this planet,
5
13000
1000
1.6 milliard kishi
00:26
1.6 billion people
6
14000
2000
elektr ta'minotisiz
00:28
don't have access to electricity,
7
16000
2000
muzlatish
00:30
refrigeration
8
18000
4000
yoki yoqilg'i saqlash
00:34
or stored fuels.
9
22000
2000
muammodir.
00:38
This is a problem.
10
26000
2000
Va buning natijasida
00:40
It impacts:
11
28000
2000
Kasalliklar.
00:44
the spread of disease,
12
32000
2000
ovqat va dorilarni saqlash muammosi,
00:46
the storage of food and medicine
13
34000
3000
sifatsiz hayot tarzi kelib chiqadi
00:49
and the quality of life.
14
37000
3000
va mana sizga yechim: qimmat bo'lmagan elektr ta'minotsiz muzlatish
00:52
So here's the plan: inexpensive refrigeration that doesn't use electricity,
15
40000
3000
... propan, gaz, kerosin yoki kerakli moddalar
00:55
propane, gas, kerosene or consumables.
16
43000
5000
termodinamika bilan o'tkazilgan vaqt
01:00
Time for some thermodynamics.
17
48000
2000
Qisqasi, 29 yil oldin, mening Termokimiyo ustozim
01:02
And the story of the Intermittent Absorption Refrigerator.
18
50000
3000
absorbsiya ( singdirish) va muzlatish haqida gapirgan edi
01:05
Adam Grosser: So 29 years ago, I had this thermo teacher
19
53000
3000
Va uning gaplari haqida ko'p o'yladim.
01:09
who talked about absorption and refrigeration.
20
57000
1000
U ko'proq Stilring dvigateliga o'hshardi
01:10
It's one of those things that stuck in my head.
21
58000
2000
-judayam qiziqarli lekin u bilan nima qilishningni bilmaysan.
01:12
It was a lot like the Stirling engine:
22
60000
1000
Va u 2858chi yili Ferdinand Carre tomonidan o'ylab topilgan ediyu,
01:13
it was cool, but you didn't know what to do with it.
23
61000
2000
lekin u, dvigatel bilan hech narsa yarata olmadi,
01:16
And it was invented in 1858, by this guy Ferdinand Carre,
24
64000
3000
sababi u vaqtda, yetarli asboblar bo'lmagandi.
01:19
but he couldn't actually build anything with it
25
67000
1000
Va bir ajoyib Kanadalik, Povel Crosli
01:20
because of the tools of the time.
26
68000
3000
1928 yili muz-shari degan narsani reklama qildi,
01:23
This crazy Canadian named Powel Crosley
27
71000
3000
va bu judayam yahshi fikr edi,
01:27
commercialized this thing called the IcyBall in 1928,
28
75000
2000
lekin men hozir bu nima cuhun ishlashga qo'l kelmaganini aytaman.
01:29
and it was a really neat idea,
29
77000
2000
Lekin avval uning qanday ishlashini tushuntirib o'tay.
01:31
and I'll get to why it didn't work,
30
79000
1000
Hullas unda ikkita shar, orasida masofa bilan ajratilgan.
01:32
but here's how it works.
31
80000
1000
bittasida ishlatiladigan suyuqilik, suv va ammonia
01:34
There's two spheres and they're separated in distance.
32
82000
2000
va ikkinchisi esa kondensator.
01:36
One has a working fluid, water and ammonia,
33
84000
2000
Issiq tomoni yanada isitiladi.
01:39
and the other is a condenser.
34
87000
1000
Va ammoniya bug'lanadi
01:40
You heat up one side, the hot side.
35
88000
2000
va ikkinchi tomonida esa u to'planib boradi.
01:42
The ammonia evaporates
36
90000
1000
va uni hona temperaturasigacha sovishini kutamiz,
01:43
and it re-condenses in the other side.
37
91000
2000
undan keyin, ammoniya qayta bug'lanib suv bilan qo'shiladi.
01:46
You let it cool to room temperature,
38
94000
1000
ilgarigi issiq tomonida esa
01:47
and then, as the ammonia re-evaporates and combines with the water
39
95000
4000
juda katta sovitish ta'sirini beradi.
01:51
back on the erstwhile hot side,
40
99000
1000
Aslida bu narsaning ishga tushirlamgani yahshi bo'ldi: chunki u yorilib ketdi.
01:52
it creates a powerful cooling effect.
41
100000
2000
Chunki, ammoniya ishlatish bilan juda yuqori bosim paydo bo'ladi
01:55
So, it was a great idea that didn't work at all: it blew up.
42
103000
3000
agarda siz uni noto'g'ri isitsangiz.
01:58
Because using ammonia you get hugely high pressures
43
106000
5000
Bosim 400 pikseldan oshib ketgandi. Ammoniya esa zaharli modda. Va u hamma yoqqa sochilib ketgandi.
02:03
if you heated them wrong.
44
111000
1000
lekin baribir, bunday hosiyatli muzlatish usuli juda qiziq fikr edi.
02:04
It topped 400 psi. The ammonia was toxic. It sprayed everywhere.
45
112000
4000
Hullas, 2006 yildning nimasi zo'r
02:08
But it was kind of an interesting thought.
46
116000
2000
- komyuterlashtirilgan hizoblash usuli bor.
02:10
So, the great thing about 2006 is
47
118000
3000
Biz, Standfordagi Termodinamika bo'limidaglar birga shu ish ustida
02:13
there's a lot of really great computational work you can do.
48
121000
3000
ishlashga yig'ildik
02:16
So, we got the whole thermodynamics department
49
124000
3000
Juda ko'p harakatdagi suyuqilklar ustidagi hisoblashlardan keyin
02:19
at Stanford involved --
50
127000
1000
ko'pchilik ammoniya muzlatish jadvallar hato ekanligini asoslab berdik.
02:20
a lot of computational fluid dynamics.
51
128000
1000
Biz bi necha zaharli bo'lmagan va past bosimda ishlatsa bo'ladigan
02:22
We proved that most of the ammonia refrigeration tables are wrong.
52
130000
3000
muzlatadigan moddalrni topdik.
02:25
We found some non-toxic refrigerants
53
133000
3000
Britaniya birlashgan Qirolligidan bir guruh
02:28
that worked at very low vapor pressures.
54
136000
1000
muzlatgichlar bilan ishlay oladigan ajoyib odamlar kelishdi
02:29
Brought in a team from the U.K. --
55
137000
3000
Britaniyda ular bor-da!
02:32
there's a lot of great refrigeration people,
56
140000
1000
va biz sinov uchun apapratni qurdik, va
02:33
it turned out, in the U.K. --
57
141000
2000
chindanham, past bosimli, zaharsiz muzlatgiz ishlab chiqara oldik.
02:35
and built a test rig, and proved that, in fact,
58
143000
2000
Men sizga bu qanday ishlashini aytay endi
02:37
we could make a low pressure, non-toxic refrigerator.
59
145000
3000
Siz uni oddiy gulhan ustiga qo'yasiz
02:41
So, this is the way it works.
60
149000
1000
va bilamizki, dunyodagi ko'p odamlarda ovqat qilish uchun gulhan-o't yoqisha oladi,
02:42
You put it on a cooking fire.
61
150000
1000
o'tinning nima bo'lishidan qattiy nazar- tuyaning ahlatimi yoki otinmi, hullas
02:43
Most people have cooking fires in the world,
62
151000
2000
30 daqiqa davomida isitib, bir soat davomida sovitiladi
02:45
whether it's camel dung or wood.
63
153000
1000
va buni biror bi konteinerga, idishga solib qo'ysa
02:47
It heats up for about 30 minutes, cools for an hour.
64
155000
3000
24 soat davomida muzlatgiz rolini o'ynaydi.
02:50
Put it into a container
65
158000
2000
Va uning ko'rinishi man bunday bo'ladi. Bu beshinchi turi. Hali butunlay ishlab tugatilmagan.
02:53
and it will refrigerate for 24 hours.
66
161000
2000
Og'riligi 3.7 kg, va ishlash mehanismi bunday:
02:55
It looks like this. This is the fifth prototype. It's not quite done.
67
163000
3000
siz buni 15 literli ( tahmiman 3 gallon) sig'im ichiga qo'yasiz
02:59
Weighs about eight pounds, and this is the way it works.
68
167000
3000
va u muzlash darajasidan
03:02
You put it into a 15-liter vessel, about three gallons,
69
170000
3000
3 daraja yuqorigacha sovitadi.
03:06
and it'll cool it down to just above freezing --
70
174000
2000
24 sota davomida, 30 daraja bo'lgan joy uchun bu juda arzon usul.
03:08
three degrees above freezing --
71
176000
1000
Biz bunday kattalikdagi muzlatgichlarni 25 dollar atrofida harajat qilib qura olamiz...
03:10
for 24 hours in a 30 degree C environment. It's really cheap.
72
178000
3000
kichikroq hajmdagilarini esa 40 dollar desa bo'ladi.
03:13
We think we can build these in high volumes for about 25 dollars,
73
181000
3000
Va biz hamma ishlata oladigan
03:16
in low volumes for about 40 dollars.
74
184000
2000
muzlatgiz ishlab chiqara olamiz deb o'ylaymiz.
03:18
And we think we can make refrigeration
75
186000
2000
Rahmat.
03:21
something that everybody can have.
76
189000
1000
(Qarsaklar)
03:22
Thank you.
77
190000
