Mhepo yese yemudenga ine imwe huwandu hwemvura yemvura. Zvino, fungidzira mamiriro ekunze seyekuputika kukuru, zvishoma zvinonyunguduka. Kana tikanyudza chipanje kwazvo chakaoma, mvura yakadonhedzwa inodonha kunze. Izvo zvakafanana zvinoitika kana mhepo ikamanikidzwa, zvinoreva kuti kusungwa kwemvura kunowedzera uye aya mvura yemvura inodzora mumvura yemvura. Kuti udzivise matambudziko neiyo yakarongedzwa yemhepo system, uchishandisa iyo yekutonhorera inotonhorera uye yekuomesa michina inodiwa.
Silica Gel, activated alumina uye molecular sieve inogona adsorb mvura uye zadzisa chinangwa chekubvisa mvura mumhepo yakamanikidzwa.
Joozeo mutengesi munhu achataura zvakasiyana adsorption mhinduro, maererano nezvinodiwa zvakasiyana, Dew Point zvinodiwa kubva -20 kusvika -80 ℃; Uye zvakare ipa vatengi ne adsorption uye desorption data ye adsorbent pasi pemamiriro akasiyana ekushanda.
