Chowumitsira chimatanthawuza chipangizo chomwe chimagwiritsidwa ntchito poumitsa chinthu pogwiritsa ntchito mphamvu ya kutentha pofuna kuchepetsa chinyezi cha zinthu.Chowumitsira chimatulutsa chinyezi muzinthu (nthawi zambiri chimatanthawuza madzi ndi zigawo zina zamadzimadzi zosasunthika) potenthetsa kuti tipeze chinthu cholimba chokhala ndi chinyezi chodziwika.Cholinga cha kuyanika ndikukwaniritsa zofunikira zogwiritsira ntchito zinthu kapena kukonza zina.Zowumitsira zimagawidwa m'mitundu iwiri, zowumitsira zowumitsira wamba ndi zowumitsa, kutengera mphamvu yogwira ntchito.Mfundo zogwirira ntchito za zowumitsira adsorption ndi zowumitsira kuzizira zimayambitsidwanso mwatsatanetsatane.

1. Ntchito Mfundo ya Adsorption Air Dryer

Chowumitsira adsorption chimakwaniritsa kuyanika ndi "kusintha kwapanikizi" (mfundo yosinthira kusinthasintha kwa adsorption).Chifukwa mphamvu ya mpweya yosunga mpweya wa madzi ndi yosiyana kwambiri ndi kupanikizika, mpweya wina wowuma (wotchedwa regeneration air) umafooketsa ndikuwonjezedwa ku mphamvu ya mumlengalenga.Kusintha kwamphamvu kumeneku kumapangitsa mpweya wowonjezedwa kuti uume kwambiri ndikudutsa mumpweya wosalumikizana.Mu gawo lopangidwanso la desiccant (ndiko kuti, nsanja yowumitsa yomwe yatenga mpweya wokwanira wa madzi), mpweya wowuma wowuma umatenga chinyezi mu desiccant ndikuchichotsa mu chowumitsa kuti chikwaniritse cholinga cha dehumidification.Zinsanja ziwirizi zimagwira ntchito mozungulira popanda gwero la kutentha, mosalekeza kupereka mpweya wouma, woponderezedwa ku makina a gasi.

2. Mfundo yogwiritsira ntchito chowumitsira mpweya mufiriji

Chowumitsira firiji chimachokera pa mfundo ya refrigeration dehumidification.Mpweya wopanikizidwa womwe umatulutsidwa mu kompresa ya mpweya umatsitsidwa ndi firiji yotsekedwa kwathunthu, ndipo kuchuluka kwa nthunzi yodzaza ndi madontho amafuta omwe ali mmenemo amalekanitsidwa.Kuchita.Pomaliza, potulutsidwa ndi chowumitsira chodziwikiratu, gasi wotenthetsera wotenthedwayo amalowa mu chowumitsira kutentha kwanthawi yayitali, kusinthanitsa kutentha ndi mpweya wowuma wotsika kuchokera mu evaporator, ndikulowa mu evaporator ya chowumitsira choziziritsa.Kuziziritsa firiji dongosolo pambuyo kuchepetsa kutentha.Kusinthana kwachiwiri kwa kutentha ndi mpweya wa refrigerant kumachepetsa kutentha kwapafupi ndi kutentha kwa vaporization kwa refrigerant.Pazigawo ziwiri zoziziritsa, mpweya wamadzi mu gasi woponderezedwa umakhazikika kukhala madontho amadzi amadzimadzi omwe amalowetsa mpweya mu cholekanitsa cha nthunzi kumene amasiyanitsidwa.Madzi amadzimadzi akugwa amatulutsidwa kunja kwa makinawo kudzera mu drainer yodziwikiratu, ndipo mpweya wowuma wowuma womwe kutentha kwawo kwatsika umalowa mu pre-cooler ndikusinthanitsa kutentha ndi pre-cooler.Mpweya wonyowa kumene walowa kumene, womwe wawonjezera kutentha kwake, umapereka mpweya wouma wouma womwe uli ndi chinyezi chochepa (mwachitsanzo, mame otsika) komanso chinyezi chochepa pamlengalenga wa chowumitsira kutentha.Panthawi imodzimodziyo, gwiritsani ntchito mokwanira mpweya wozizira wa mpweya wotuluka kuti muwonetsetse kuti makina a firiji amatsitsimutsidwa ndi mpweya wabwino pamakina a makinawo.Zowumitsira firiji zakhala chisankho choyamba ngati zida zoyeretsera ma air compressor station m'mafakitale osiyanasiyana chifukwa cha magwiridwe antchito odalirika, kasamalidwe kabwino komanso mtengo wotsika.
