Designing a Dedicated Outdoor Air System with Ceiling Radiant Cooling Panels

The concept of a dedicated outdoor air system (DOAS) with parallel sensible cooling was born from the decoupled system concept, which can be summarized as decoupling of ventilation and air-conditioning functions, or decoupling of sensible and latent load functions. First, remove the latent loads from the outside air (OA) intake and generated in spaces using a 100% OA ventilation system (i.e., DOAS). Second, remove the space sensible loads using a parallel mechanical cooling system, such as fan coil units, conventional variable air volume, and ceiling radiant cooling panel (CRCP) independent of the ventilation system.
