Abstract
An air conditioning system includes an outdoor air latent cooling treatment stage providing parallel airflow with a return air sensible cooling treatment stage. A mixer mixes the treated outdoor air with the return air to form the conditioned space supply air. A first relative humidity controller monitors the outdoor air relative humidity and separates the outdoor air from saturation to maintain relative humidity in outdoor air ducting below a predetermined mould growth limit. A second relative humidity controller monitors the conditioned space supply air relative humidity and separates the space supply air from saturation to maintain relative humidity in space supply air ducting below a predetermined mould growth limit. The outdoor air latent cooling treatment stage includes a dehumidification heat exchanger, combination pre-cooling and heat reclaim heat exchangers, or a heat transfer pump. The return air sensible cooling treatment stage includes at least a sensible cooling heat exchanger.
