Efficiency Comparison Using AHRI-920 Efficiency Ratings for DOAS

DOAS Dedicated outdoor air systems are often applied in humid climates for improved indoor air quality. Various options are available for DOAS and recent ASHREA modelling method AHRI-920 provided a basis for design comparison. In this paper we look to compare various options for this including Desiccant systems, which would provide a quick guide for system viability. 
Part of the comparison will incorporate design considerations such and waste heat service use, and internal latent load assumptions to provide a comparative model.
