ABSTRACT:
An air conditioning apparatus for a clean room has a filter for removing harmful chemicals provided in the return opening of an air-conditioner. In normal operation where there is no chemical leakage, circulating air in the clean room by-passes the filter. When chemicals and the like leak, the circulating air is caused to pass through the filter by operating shutters in order to remove the chemical mist and the like contained in the circulating air.
