The present invention relates to supplying air to a manufacturing site. In order to provide an air supply for a manufacturing site with improved energy efficiency, where contaminated air can also be handled, an air supply system (10) for a manufacturing site is provided that comprises a desiccant and evaporative cooling arrangement (12) and an exhaust air scrubber (14). Further, first air supply conduits (16) from the desiccant and evaporative cooling arrangement to at least one contaminated air generating indoor space (18) are provided, and secondary disposal conduits (20) from the at least one contaminated air generating indoor space to the exhaust air scrubber and to the desiccant and evaporative cooling arrangement. The desiccant and evaporative cooling arrangement is configured to condition fresh outdoor air (22) as input air for the use in the contaminated air generating indoor space. The first air supply conduits are configured to provide the conditioned air as supply air (24) to the at least one contaminated air generating indoor space. The secondary disposal conduits are configured to conduct contaminated exhaust air (26) from the at least one contaminated air generating indoor space to the exhaust air scrubber, and to provide the scrubbed air to the desiccant and evaporative cooling arrangement. The exhaust air scrubber is configured to remove air contamination (30) to a predefined amount, wherein the predefined amount is set such that the air can be used further in the desiccant and evaporative cooling arrangement. Further, the scrubbed air is used for at least one of the group of cooling the input air by heat recovery, and desiccating a drying agent of the desiccant and evaporative cooling arrangement. |
