Research on energy-saving measures for high-level biosafety laboratories based on energy consumption simulation

To understand the energy-saving effects of different technical measures on high-level biosafety laboratories, an energy consumption model was established and the annual operating energy consumption was simulated and verified. On this basis, the operating energy consumption was calculated and analyzed under different air changes and return air ratios. A zoning design concept for air conditioning systems was proposed based on biological risk levels, and the energy-saving effect was analyzed. The results indicate that introducing return air has a more significant energy-saving effect than reducing air changes, but a thorough risk assessment should be conducted before design.
