Relax, are you somehow afraid that by posting not-all-that-informative posts that he will catch up to your postcount and by doing so deflate your ego?!

Any contributions made on forums usually arrise from the OC-ers need to share knowledge though some times it is not exactly rocket science getting posted, though it is repetative even irrelevant at times, it is a part of the living forum. Personally, i would much rather have posts like 404's which were atleast written with good humor, than posts of envy, hatred or even a dead forum...

Oh, and cold_ice its the 10th by my watch we better start seeing some updates...:toast:

Thanks

Waiting for some new parts, the gases and for the special oil. Be patient, I hope there will be an update next week.

Today I changed the SC18CLX from the second stage for a new SC21CLX. I will use the SC18CLX in the third stage. Furthermore I changed the desuperheater for a new, and bigger one. This one will be used for all 3 stages. The receiver will bes used as expansion tanks for the third and fourth stage.
I have already ordered the Methane, I hope I will get a good offer for the Tetrafluormethane next week.

No expansion tank for the second stage? You'll need to put in a lot of ethylene I think.

You might be right. I have a very big receiver here (I think it has 3l), when I need one I can use this one.

just remember that you shouldn't charge while the system is running.

This thing is gonna be friggen insane. When are you going to have that seperate circuit breaker installed? :D

could someone expain the use of an expansion tank in detail? What's the profit on having more gas stored in a tank doing nothing??

what is bp of tetrafloromethane?

which is for forth stage methane or tetrafloro?

Expansion tank is used to decrease static pressure in unit when you use high pressure refrigerant. ET has very big capacity, so there is place for the refrigerant to expand (you have extra volume in the system, that allows to reduce static pressure).

Of course, it`s attached to suction line.

the_new_guy

is it same as a suction line accumulator?

Suction line accumulator is smaller than expansion tank will be, and ET should be connected by this way (not like accumulator):

One question, what size of captube and what lenght should be used to connect the expansion tank to the suction line?

Tetrafluormethane is R14, so the boiling point is about -128°

@cold_ice - You can use 0,9mm cap tube or 2,3mm, it will be ok :) Lenght...I don`t think so that it does matter, I used ~20cm of 0,8mm in my cascade and it worked well.

yeap, i doesn't really matter. but i would use 1/4" or 3/8" for a faster startup as i have to wait about 3-4 mins untill all the gas gets sucked out of my expansion tank through the 0.9mm cap tube

cold_ice

Ok thx. Maybe I will try 1/4" or really big captube.
