Recover cooling energy from Nitrogen Vapour Exhaust / Air mix
Recover cooling energy from Nitrogen Vapour Exhaust / Air mix
(OP)
Does anyone know of a way to recover the cooling energy from a liquid nitrogen vapour / air mix coming out of a Liquid Nitrogen freezing process? The vapour mix is at -80F and flowing at 3000 CFM. Snow flakes are generated at the fan exit on the roof from the moisture in the air from the process room. A dual exhaust fan set-up is being used because the stainless squirl cage fans do freeze up occasionally.
Goal is to transfer some of this cooling energy to cool an existing room.

A single pass exchanger would leave you with a block of ice on the warm side.

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor
