Need suggestions for load calculations for ultra cold rooms

Need suggestions for load calculations for ultra cold rooms

(OP)
Hey guys, let's see if I can pick your brains.

I have a project in a research facility that will have an ultra cold room serving as a research area that will be held at -65F.  Yeah.
I have various options in terms of refrigerants and heat sinks, and I'm trying evaluate them better, so I'm looking for some software that will aid me in this.  Ideally, it would be software that would allow me to enter the room and load specifics, calculate the total load, then allow me to simulate how systems based on various refrigerants will perform in this service.

Any ideas?

Ahh, I hit 'post' too soon.  I wanted to mention that I've looked around and found various "cold room" applications.  However, these just calculate loads for product holding rooms (think large frozen food freezers), aren't suitable for my application, and really won't calculate down to -65F.

Also, if you know of two different applications that'll help me, I'm open to that.  Perhaps one to do the room loading and one to simulate the refrigeration systems.
