Refrigeration question

[R3v3lation]

hey everyone. I had a question about fridge cooling.

Could you combine multiple smaller systems(that alone could maybe reach temps of -10c or so) to get a lower temp, or would it still not be able to get past -10c?

yea it would work but adding a peltier might be a lot less bulky

You can combine multiple units but they should be matched. This would be useful for staged cooling. An example would be if you have a high cooling requirement then combining say two units that both have terminal temp of -10C you could run the coolant into a primary res containing the first evaporator and then have an overflow arrangement into the second res where the pump would feed back into the circuit. You cannot have two units that are not identical. Say the main unit working at -25C and the other at -10C. The reason for this is that coolant is heated roughly 0.2C as it passes through the w/b. The coolant would be at -25C out of the main res but passed to a second res at -10C thus heating the coolant.

Or you could get one big unit that pulls tons of btu's

still wouldn't cool as well as 2 stages

Apparently you've never worked on a blast chiller, lol

Tiger, I don't really know enough about this to understand what you said, but thanks anyways.

Could someone maybe point me to a web page that has more info on this, so I could read up on it some more?

thanks

One of the fastest around that I know of is using chilled water on tecs to get extreme speed.

personaly id get a small refridgerant system for your self and then hook up a decent watt low delta T peltier they are around you have to look for them or get them custom made. like somthing that can transfer 150W of heat at a delta T of like 20-30C you could get your cpu realy close to the -40C limit
