Short term, Light weight, Low volume Refrigeration Design

AI Thread Summary
The discussion focuses on designing a lightweight and compact refrigeration system to maintain a temperature of approximately 5 degrees Celsius in a shoe box-sized volume for 20 minutes. The project constraints emphasize a weight limit of less than 1 kg and minimal space usage. Participants suggest exploring alternatives to dry ice for temperature control. Ideas for achieving efficient cooling within these parameters are encouraged. The conversation highlights the challenge of balancing performance with size and weight limitations.

Hello Guys,

This is my first time posting here - just wondering if anyone has some insight on a project that I am working on. I want to be able to temperature control an insulated shoe box sized volume at ~5 degrees Celsius for about 20 minutes. The main constraints are that I would need the temperature control system to be lightweight (<1kg) and occupy only a small fraction of the shoe box volume.

Any ideas would be welcomed! I would rather not just throw a block of dry ice in the container, though.

You've about optimized it.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
