Preparing air for air conditioned rooms - avoids mixing primary air with recirculated air by completely separate processes of extraction filtration and cooling

摘要

A method of preparing air for an air conditioning plant consists of extracting room air and succeeding fresh air in order to cool the room. This air is replaced by fresh outside air with minimal negative temperature difference. Room air in controlled quantities is extracted, filtered and cooled back by using the ice storage, and reintroduced into the room (10). The preparation of primary air and recirculated air is separated so that only the primary air, under strict avoidance of mixing with room air, is introduced into the work area. USE/ADVANTAGE - Improves hygiene in air conditioned rooms by preventing primary and recirculated air from mixing.
