00:01
And we have these requirements that is given to us.
00:05
Okay, temperature.
00:08
It's 3 celsius.
00:14
This entropy kilojou per kilogram kilogramme kelvin.
00:24
So, have this.
00:28
For vapor compression system, okay.
00:38
Point one, point two.
00:41
Let's call these two prime and core year two.
00:45
Or year three, year four.
00:51
Now, at this temperature, and the system is to work on a condenser temperature should be this, 30 degrees celsius, while at the evaporator, zero degree.
01:10
Okay? and the maximum pressure should not exceed 10 bar, 10 bar, and the minimum, and the minimum, minimum, one bar, all right? so which refrigerant? and we are given a list of refrigerants.
01:43
So which one are we going to use? okay.
01:48
So let's see.
01:49
Oh, we just need, let's just tabulate some things.
01:52
And see for ourselves.
01:55
We're able to meet that requirement.
01:58
We have refrigerants, refrigerant, refrigerant, refrigeratorant, okay, and we have at zero degree, zero degrees celsius, we have 30 degree celsius, okay.
02:36
We have bar, p in bar, pressure, bar, okay, and we have pressure bar, pressure in bar, okay? do something like this, okay? like this.
03:10
Now let's see, we have, let's say, for one of the restaurant is arrow refugent 22.
03:17
The other one is refrigerant, one.
03:25
34a other one is ammonia ammonia and another one is propane okay now you can see if we go to the property tables at the table at zero degree for okay we'll find out that uh this to be 4 .9 9 .1.
04:22
Sorry, 98...
