[ayat]

Is there somebody help me ?
I want to make a freezer with -40 C ,
single stage , R22 refregerant , single phase power,
about 0.8 cubic meter volume 80W 100H 100L Cm, capacity about 150 KG of stuff,
speed of cooling rate is 4 hours +40 to -40, ambient temp. is +40 C, isolation is 7.5 Cm rock wool.

at -40sst and 45sct you are asking a lot out of an R22 single stage machine, you would be better off with 2 stage or a different refrigerant.

you can download copeland select from here: http://www.ecopeland.com/download.cfm?what=download


you say load is 150kg of "stuff", what sort of "stuff"?

Thank you for your advice, and about stuff I think we can simulate it by 150 Kg of iron.
