Dear all,
I hope this is a place where I can ask a question in the forum.
WHO PQS-qualified refrigerators used frequently at the health facility level (E003) have a holding capacity measured by a particular WHO testing process. However, most fridges also have certain limitations on that holding capacity when used in practice. For example, the spatial geometry of the refrigerator or the ice-pack linings may result in unusuable dead space in the corners and edges. Also, shelf placement creates dead space in between vaccine carton packages. These conditions make it difficult to estimate the number of vials or doses of a particular vaccine that can fit in a fridge (including when given the secondary packaging's "dose-per-cc of cold chain space" measurements).
What is a reasonable estimate for the number of vials that can fit in a fridge with a payload storage volume of x liters? What might be a variance on this value, and what does the variance depend on? Put another way, what is an estimate for the amount of so-called "dead space" in a fridge of volume x liters?
Thanks very much in advance for this discussion.
