Pamene kutentha kwa nthunzi kwa makina osungiramo zinthu zozizira kuli kotsika kuposa 0 ° C, chisanu chidzaonekera pamwamba pa evaporator, zomwe zimakhudza momwe kutentha kumayendera bwino. Chifukwa chake, kusungunula nthawi zonse ndi gawo lofunika kwambiri pakusamalira malo osungiramo zinthu zozizira. Pali njira zambiri zosungunula. Pakadali pano, opanga nyumba zosungiramo zinthu zozizira amagwiritsa ntchito njira zisanu: kusungunula zinthu zopangidwa ndi anthu, kusungunula zinthu zamagetsi, kusungunula zinthu zozizira m'mpweya wotentha, kusungunula zinthu zozizira m'madzi, kusungunula zinthu zozizira m'madzi otentha.
1. Kusungunula chisanu ndi manja ndi kuchotsa pamanja chisanu pamwamba pa chubu chotulutsira evaporator. Njira iyi ikhoza kuchitika popanda kuyimitsa zida zoziziritsira. Njirayi imatenga nthawi yambiri komanso yotopetsa, ndipo kusungunula chisanu ndi koipa.
2. Kusungunula kwa magetsi ndi kukhazikitsa chotenthetsera chamagetsi pa evaporator kuti chisungunule ndi kutentha kwamagetsi. Mukasungunula, siyani compressor kapena siyani kupereka madzi ku evaporator. Kusungunula kwa magetsi kuli ndi ubwino wotsika mtengo komanso kosavuta kuwongolera, koma mtengo wogwirira ntchito ndi wokwera. Nthawi zambiri amagwiritsidwa ntchito posungunula zida zosungiramo zozizira, osati posungunula zida zoziziritsira. Pa kutentha kosiyanasiyana, zofunikira pa luso loteteza kutentha ziyenera kukhala zosiyana, ndipo mphamvu yoziziritsira yofunikira iyeneranso kukhala yosiyana. Kukhazikitsa malo osungiramo ozizira kuyenera kusinthidwa malinga ndi malo enieni ogwiritsira ntchito ndi momwe kasitomala amagwiritsira ntchito, pokhapokha ngati palibe chifukwa chapadera chotsatira njira yokhazikitsira.
3. Kusungunula mpweya wotentha ndi kugwiritsa ntchito nthunzi yotentha kwambiri yotulutsidwa ndi compressor kuti itulutse kutentha mu evaporator ndikusungunula wosanjikiza wozizira pamwamba pa evaporator. Dongosolo losungunula mpweya wotentha ndi lovuta ndipo mtengo wake ndi wokwera. Koma mphamvu yake yosungunula imakhala yabwino. Ikagwiritsidwa ntchito mu dongosolo la ammonia, mafuta omwe amasonkhana mu evaporator amathanso kutulutsidwa mu ngalande kapena m'malo osungira mpweya wochepa. Mu ndondomeko yosungunula mpweya wotentha, kuthamanga nthawi zambiri kumayendetsedwa pa 0.6MPa. Yesani kugwiritsa ntchito mpweya wothamanga kwambiri wotulutsidwa kuchokera ku compressor imodzi kuti musungunule. Nyengo yozizira ikhoza kukhala yoyenera kuchepetsa madzi ozizira kapena kuchepetsa kuchuluka kwa ma condenser, kuwonjezera kutentha kwa utsi, kufupikitsa nthawi yosungunula. Pa machitidwe a ammonia, ammonia yotentha yosungunula iyenera kulumikizidwa ku chitoliro chotulutsa utsi cha cholekanitsa mafuta.
4. Kusungunula madzi ndi kupopera madzi pamwamba pa evaporator ndi chipangizo chothira madzi kuti asungunule chisanu. Dongosolo losungunula madzi lili ndi kapangidwe kovuta komanso mtengo wake ndi wokwera, koma zotsatira zake ndi zabwino komanso mtengo wake ndi wotsika. Kusungunula madzi kumangochotsa chisanu pamwamba pa evaporator, ndipo sikungathetse mavuto omwe mafuta amasonkhana mu evaporator pa kutentha. Chofunika kwambiri ndi bolodi losungiramo zinthu zozizira, lomwe nthawi zambiri limapangidwa pasadakhale ndi wopanga bolodi losungiramo zinthu zozizira ndipo lili ndi kutalika, m'lifupi ndi makulidwe okhazikika. Bolodi losungiramo zinthu zozizira la makulidwe a 100mm nthawi zambiri limagwiritsidwa ntchito posungiramo zinthu zozizira kutentha kwambiri komanso kwapakati, bolodi losungiramo zinthu zozizira la makulidwe a 120mm kapena 150mm nthawi zambiri limagwiritsidwa ntchito posungiramo zinthu zozizira kutentha kochepa komanso zozizira.
5. Kusungunula madzi otentha mumlengalenga ndi njira ziwiri zosungunula madzi otentha ndi kusungunula madzi zomwe zimagwiritsidwa ntchito nthawi imodzi, zomwe zimaika patsogolo ubwino wa zonsezi, ndipo zimatha kuchotsa mwachangu komanso moyenera chisanu pamwamba pa evaporator ndikuchotsa mafuta omwe ali mkati mwa evaporator. Mukasungunula, mpweya wotentha umatumizidwa koyamba mu evaporator kuti ulekanitse chisanu pamwamba pa evaporator, kenako madziwo amathiridwa kuti atsuke mwachangu chisanu. Madzi akadulidwa, pamwamba pa evaporator "pamauma" ndi mpweya wotentha kuti ateteze filimu yamadzi pamwamba kuti isazizire ndikukhudza kusamutsa kutentha. Kale, opanga ma board osungira ozizira ankagwiritsa ntchito polyethylene ndi polystyrene ngati zipangizo. Tsopano pali ntchito yabwino ya polyurethane sandwich board. Kuchuluka kwa zinthu zoteteza thovu la polystyrene ndi kochepa, sikungathe kutetezedwa. Nthawi zambiri amagwiritsidwa ntchito muzipangizo zapadera. Polyethylene ndi chinthu chabwino chopangira zinthu zopangira. Kudzera mu chiŵerengero china, imatha kuchotsedwa thovu kuchokera ku kuchuluka koyenera, mphamvu yoteteza imakhala yabwino, mphamvu yonyamula ya zinthu zotetezera imakhala yolimba. Mbale ya polyurethane ndi yabwino, ili ndi ntchito yabwino yotetezera kutentha ndipo simatenga chinyezi, koma mtengo wosungiramo zinthu zozizira uwu ndi wokwera pang'ono.
