Hello, i am relatively new to subzero cooling. I have a little devil evaporator, 1hp condenser and an aspera 1/8 hp. I tried two times make it work, using r404a,but i failed. Can anyone help me fix it please?

It would seem that you need to do some reading and finding a friend with the same interest.

We cannot see your system from here and without any fact or figures your request is impossible to answer.

What exactly would you like to know. I have pictures, and pressures, which were wrong, and thats why it didnt work i think.

OK,

What are the pressures/temperatures
Sub-cooling, superheat

If you don't supply the information we are not going to spend time dragging it out of you bit by bit. :(

Subcooling it had about 1 bar, superheat around 6.7 bar. Reading more about single stages and asking i think that superheat preasure should be about 200psi on load.

Hello Nickolaos.

You have all the descriptions wrong mate.
It is either a lanuage thing or you don't quite understand
what is being asked of you.

We need to know specific pressures and temps throughout the
system to have any sort of idea.

I'll give you the benifit of the doubt and put it down to language.

So you need to give us

Suction pressures
Discharge pressures
Temp of suction pipe from the evaporator
Temp of liquid pipe from condenser

Then we need

Air onto and off of the evap and Condenser.

Then we need to know what you are cooling and what type of environment
it is in.

Extra things like is it cappilary, TEV, Temp range and other things like that.

If you give us all the information we might be able to talk about
things, but untill then we are just guessing.
