[T Samarasinghe]

Thank you very much

[Birdman]

You are welcome. If my answer helped, can you accept it?

[T Samarasinghe]

I accepted it.

[T Samarasinghe]

Do you know the way of connecting this refrigeration system to another system

[Birdman]

What do you mean by connecting?

Answer 2

[T Samarasinghe]

I want to use this refrigeration system to cool another system. Can't I use it?

[Birdman]

Of course you can use it but I can not give more detailed answer unless you provide me some detail.

[T Samarasinghe]

This is my system. and in this system I need to connect this refrigeration system to flow resistance tube hence it is at 1100 degrees. and thereafter I want to get the differential pressure between port A and B

[T Samarasinghe]

and I include this system to the refrigeration compartment environment temperature component. Also I used this to environment temperature component too. but still there is no change in differential pressure.

[Birdman]

Ok. What does flow resistance tube look like? Where is it?

[T Samarasinghe]

[Birdman]

Is it just the orange part?

[T Samarasinghe]

no, the pink colour thing, local restriction (G)

[Birdman]

Seems like you made some connections. Do you receive modelling error or logic error?

[T Samarasinghe]

no..i didn't receive any error

[T Samarasinghe]

This is my system

[T Samarasinghe]

in this system I want to connect this refrigeration system (instead of pressure and temperature sensor 1)to port A and port B of local restriction (G).

[Birdman]

I still didn't understand what you ask. You saw that you can connect two systems. So?

[T Samarasinghe]

I want to cool down the local restriction. so how I need to connect this local restriction and the refrigeration system.

[Birdman]

Ok, then the first thing is to ask this:

-How did you connect those two systems? According to a mathematical background, or randomly?

[T Samarasinghe]

mathematical background

[Birdman]

Can you share the mathematic of it so that I will understand both systems?

[T Samarasinghe]

do you mean the logic ?

[Birdman]

Yes, the formulas.

[T Samarasinghe]

there are no formulas. However, what we need to do is to measure the differential pressure between port A and Port B and then we have to connect the refrigeration system to cool the local restriction. Then through the refrigeration system we need to measure the differential pressure between these two ports.

[Birdman]

But to do so, first you need to known the physical background of it. After that, try something and then ask questions. This way I might not be much help to you.

[T Samarasinghe]

the physical background is the differential pressure is proportional to the density and the mass flow rate of the air. here I am considering constant mass flow rate. therefore the only variable is density. and due to the temperature variation (before and after the installation of refrigeration system) the differential pressure should be reduced. But for my connections the reduction doesn't happen.
