VALVELESS LOW PRESSURE AIR DEHUMIDIFIER

摘要

A low pressure air dehumidifier is disclosed in which damper means responsive to pressure caused by air flow from air intake blowers controls the flow of air through the dehumidifier. Where the dehumidifier includes two adsorbent beds having alternating drying and regeneration cycles, the blowers are operated alternately to thereby cause one vent means to open and allow moist air to flow through a drying bed. During this time the other blower is off and the other vent means is closed. The two adsorbent beds are connected on their downstream sides so that dry air leaving one of the beds flows through the other bed to thereby regenerate the latter.
