Abstract: Laboratories with air-conditioning system in hot and humid areas consume much more air-conditioning energy than conventional public buildings. One of the most important reasons is that energy consumption from air-conditioning fresh air, caused by exhaust air, accounts for a large proportion of air-conditioning energy consumption in the laboratories in hot and humid areas. An independent fresh air-supplementary air system is proposed to minimize the fresh air volume and load from fresh air in the laboratories, and the energy saving effect of this system is analyzed in combination with a practical case. The results show that the energy saving rate of the "multi-split air conditioner + divided function fresh air-supplementary air" air-conditioning system based on the divided function design is up to 65.6%, compared with the conventional "multi-split air conditioner + fresh air" air-conditioning system.

Key words: laboratories, air-conditioning and ventilation, fresh air, energy consumption
