Energy saving potential of air heat exchanger in chilled ceiling air conditioning systems

Calculates the fresh air energy comsumption of chilled ceiling system combined with displacement ventilation and mixing ventilation respectively by adopting different air heat exchanger combination schemes. The results indicate that the double air heat exchangers used simultaneously in ventilation system can eliminate the energy wasted in reheating of fresh air, and that the latent heat recovery of exhaust air is more important than eliminating reheat energy of fresh air in hot-humid area in summer. Therefore, the total heat exchanger should be used prior to others.
