The central thrust of this paper is to develop a clear understanding of the performance and control requirements for a dedicated outdoor air-dual wheel system. The dedicated outdoor air-dual wheel system discussed here is specifically intended to decouple all of the latent cooling from the sensible cooling done with a parallel system. The control requirements include identification of each local loop, instrumentation, control devices, sequence of operation, and a sample graphic programming language diagram. The dedicated outdoor air-dual wheel system consists of a preheat coil, an enthalpy wheel, a deep chilled water dehumidification cooling coil, and a sensible heat recovery exchanger. The imminent design para-digm shift over to the use of dedicated outdoor air systems is being restrained, in part, because of a general uncertainty about how best to control the equipment.
