Integrated hygienic cross-flow plate heat recovery units into the fresh air handling system of a pharmaceutical cleanroom, achieving 72% heat recovery efficiency, saving 860,000 kWh electricity per year and reducing HVAC energy share by 35%.
For medical clean areas such as hospital operating rooms and ICUs, a liquid-circulation energy recovery method recovers exhaust cooling or heating while preventing cross-contamination between fresh and exhaust air, reducing cleanroom HVAC fresh-air energy consumption.
