I have a bit of an ambitious project on hand and was looking for some advice/ideas.
My team and I are working on a project that involves retrofitting a commercial grade freezer (model MasterBilt IHC-48) into an environment chamber that would be used for HASS testing. HASS testing involves perform a rapid temperature cycling test and vibration/shock test, which would be used to stress electronic products.
As an example this rapid temperature cycling might involve going from +65C to -10C in 2 minutes and vice versa.
The medium inside the chamber would be air. The dimensions inside the freezer are 27"x58"x46" (0.686m X 1.47m X 1.17m).
The gray area for me is how to achieve this rapid cooling. What I am looking for are ideas/suggestions on how to retrofit this freezer to achieve this rapid cooling.
Any ideas/comments are welcomed.
