Labs run high air-change rates with potentially hazardous exhaust. Recovering that heat is valuable, but streams must never mix.
Safe recovery options
- Plate (sensible): fully separated, washable, the default for most labs.
- Heat pipe: separated and robust, good for fume-hood exhaust.
- Avoid rotary wheels: any carryover is unacceptable with hazardous exhaust.
Payback
Lab HVAC is energy-intensive; even 70% recovery on constant exhaust is a strong saving. Combine with heat pipes and the efficiency guide.
