Chiller to cool freon
Chiller to cool freon
(OP)
Hello,
Is there a device similar to a chiller that uses a refrigeration cycle to cool freon instead of water/glycol? i.e. the freon is the process liquid, to be used as a coolant. What is this device called? Where can I find information?
Thanks in advance

Imok2 is correct, cascade referigeration systems consist of two refrigeration systems, with the evaporator of the first stage, cooling the condenser of the second (low temperature) system.
They are used in low temperature applications from -30.C, I have worked on systems as low as -100.C. Cascade systems are used in the aerospace industry for environmental testing.
I have bought a couple of these chambers from a company called Montford, they worked really well.

It's not clear whether freon is to be kept in the liquid state all the time.

I have done something similar, except I used LN2 as the primary cooling and R22 as the secondary loop. R22 was chosen because at low operating temperature there is little change in viscosity thus pump requirments were not heavly impacted. R22 remained in the liquid state all the time due to system pressure and temperature range. Also the customer had severe restrictions regarding spillage, residue, etc...
We can speculate why "washford" wants to use a refrigerant for his purpose, but what he/she is asking is real and possible.
"washford" if you can please supply more information so we all can chime in with good ideas and advice.
Good Luck
