cooling load of corpse

[wenda]

Hi all..
anybody know how to calculate the cooling load corpses?
I was working on the final assignment about design of the refrigerator corpses and I am confused to calculate the cooling load.. maybe you can share with me..
thank you .. :)

The only number I know is 3470 J/Kg

Or 3.47 kJ/Kg

Hope that helps.

It's ZERO. A corpse does not produce any heat. If you want to know how much energy you need to cool it from x°C to y°C, just consider that the corpse is 70% water in weight

This is not so!

Dead bodies suffer chemical reactions called Autolysis which is basically the decomposition of the cell's enzymes and Putrefaction which is the eating of the body by bacteria that normally live inside the body.

These reactions slow down at lower temperatures, but the rate of the reactions will depend heavily on what happened to the corpse since death, specially ambient temperatures.

Pork shoulder is 2.47Kj/kg and scientists say we are simmilar to Pork.

Wives say we are similar to pork also:D

Only if your corpse were eviscerated right after death and cleaned like pork!

Maybe on the outside? :)

Most corps are cleaned from internal parts and most liquids, filled with chemicals to stop decomposition, some of them are months inside the fridge, I had the privilege of replacing an evaporator fan once in the hospital morgue, no one seamed to give a hand......

No, corpses are first classified by the cause of death, only if it is known they are treated with things like formaldehyde and this should absorb some of the thermal load.

But usually corpses arrive and are put directly into the cooler. Besides the number of corpses is variable.

I've also seen these refrigerators even with hosts inside, an 8 bed cooler with a TFH4518Y but it did have capacity control problems.

I rightfully assumed the man wants to store a corpse before it starts rotting. :rolleyes:

No again. The question is to calculate the cooling load, corpses may come under varying conditions thus I find it very difficult to give any value.

For example if it were already rotting the body's temperature could well be above it's normal temperature, less mass though.

You mentioned the water content and maybe this is a good way to estimate the load but with the body's initial water content because you can't anticipate that they will be at 70%.
