Kusankha kondensa yosungiramo zinthu zozizira kumakonzedwa makamaka malinga ndi momwe zinthu zilili pa ntchito yosungiramo zinthu zozizira.
Chokondetsa mpweya (air-type condenser) ndicho chokondetsa mpweya chomwe chimagwiritsidwa ntchito kwambiri masiku ano. Chili ndi ubwino wambiri monga kapangidwe kosavuta, mtengo wotsika, zida zochepa zogwiritsidwa ntchito, kuyika kosavuta komanso kugwiritsa ntchito zinthu zosiyanasiyana, zomwe makasitomala amakonda. Chokondetsa mpweya (air-type cold storage condenser) nthawi zambiri chimakhala choyenera zida zazing'ono komanso zapakatikati zosungiramo zinthu zozizira, ndipo palinso zochitika zina zomwe zimagwiritsidwa ntchito m'mapulojekiti akuluakulu osungiramo zinthu zozizira m'madera omwe madzi akusowa.
Mzere wa air condenser ndi radiator yopangidwira makamaka ma compressor a semi-hemetic ndi fully-hemetic; pali mitundu inayi yopangira: Mtundu wa FN, Mtundu wa FNC, Mtundu wa FNV ndi Mtundu wa FNS; Mtundu wa FN, Mtundu wa FNC, Mtundu wa FNS umagwiritsa ntchito mtundu wa side outlet, Mtundu wa FNV umagwiritsa ntchito mtundu wa top outlet.
Pogwiritsa ntchito chubu cha mkuwa cha 3/8″ ndi pepala la aluminiyamu lokhala ndi pockmarked, pepala la aluminiyamu ndi chubu cha mkuwa zimalumikizidwa kwambiri ndi chubu chokulitsa cha makina, ndipo mphamvu yosinthira kutentha ndi yapamwamba. ; Itha kugwiritsidwa ntchito pa R22, R134a, R404A ndi madzi ena ogwiritsira ntchito firiji, ndipo imagwiritsidwa ntchito kwambiri mu zida zosiyanasiyana zosungiramo firiji za Freon. Ma condenser a mtundu wa FNS amagwiritsa ntchito mphamvu yayikulu, voliyumu yayikulu ya mpweya, ma mota othamanga pang'ono, komanso kuyika mkati, mawonekedwe okongola, phokoso lotsika, ikhoza kugwiritsidwa ntchito m'mayunitsi okhala ndi phokoso lotsika; condenser ya mtundu wa FNV ili ndi mbali yayikulu yolowera mphepo, mphamvu yabwino yosinthira kutentha, ndipo ili ndi mota ya 6-pole yokhala ndi phokoso lotsika; ingagwiritsidwe ntchito m'mayunitsi akuluakulu osinthira kutentha; mitundu yosiyanasiyana ikhoza kupangidwa malinga ndi zosowa za makasitomala.
Anthu ogwiritsa ntchito malo osungira zinthu zozizira nthawi zambiri amaganizira kwambiri malo osinthira kutentha kwa condenser mu chipangizocho, makamaka chifukwa chodera nkhawa kuti ngati kusinthana kutentha kwa condenser kuli kochepa kwambiri, kuthamanga kwa condensation kudzakhala kwakukulu kwambiri nthawi yachilimwe yogwiritsira ntchito zida, zomwe zimapangitsa kuti zida zizimitsidwe kuti zisatetezeke; koma anthu ambiri amanyalanyaza kuthamanga kwa condensation kochepa. Ngati kuthamanga kwa condenser kuli kochepa, kutsika kwa kuthamanga kwa valavu yokulirapo kudzachepa, ndipo firiji yomwe imapezeka ndi evaporator idzakhala yaying'ono, zomwe zimapangitsa kuti makina oziziritsira alephere.
Mu makina oziziritsira, ngati choziziritsiracho chayikidwa panja, mphamvu yotulutsa madzi (kupanikizika kozizira) ya makinawo imakhala yotsika nthawi yozizira (kapena m'malo otentha pang'ono).
Izi nthawi zambiri zimakhala zofala kumpoto. Pa makina oziziritsira mpweya, zimapezekanso pa zipangizo zosungiramo zinthu zozizira. Ngati mphamvu yoziziritsira mpweya ili yotsika kwambiri, valavu yowonjezera singathe kupeza mphamvu yokwanira yochepetsera mphamvu m'malekezero ake awiri, zomwe zimapangitsa kuti zikhale zovuta kupatsa evaporator mphamvu yoyenera. Kumbali imodzi, mphamvu yoziziritsira ya makinawo singakwaniritse zofunikira, ndipo izi zingayambitsenso ma alarm otsika mphamvu ndi zolakwika zina mu makinawo.
Mu nyengo yozizira, makina oziziritsira amakhala ndi vuto lolephera chifukwa cha kutsika kwa mphamvu ya madzi, choncho kodi pali njira iliyonse yomwe tingapewere kuti kutsika kwa mphamvu ya madzi kukhala kochepa kwambiri mu nyengo yozizira?
1. Gwiritsani ntchito chowongolera kuthamanga kwa mpweya kuti muwongolere kugwira ntchito kwa fan nthawi ndi nthawi;
Kugwira ntchito kwa fan nthawi ndi nthawi n'kosavuta komanso kosavuta kugwiritsa ntchito, ndipo ukadaulo wake ndi wachikulire. Chowongolera chomwe chimagwiritsidwa ntchito ndi chowongolera kuthamanga, chomwe chimatha kuwongolera kuyambira ndi kuyima kwa fan nthawi ndi nthawi;
Ngati kupanikizika kuli kotsika kwambiri, zimitsani fan; ngati kupanikizika kuli kokwera kwambiri, yatsani fan; kupanikizika kwakukulu kumodzi kungasankhidwe, monga Danfoss KP5, ndi zina zotero, ndipo mtengo wokhazikitsa kupanikizika umakhazikitsidwa malinga ndi momwe zinthu zilili.
Kawirikawiri, pa mayunitsi ang'onoang'ono, mafani awiri kapena kuposerapo amagwiritsidwa ntchito, limodzi mwa iwo nthawi zambiri limakhala lotseguka, ndipo mafani ena onse amayendetsedwa ndi chowongolera kuthamanga kwa mpweya. Kuyamba kapena kuyimitsa kwa mafani kumayendetsedwa ndi kuchuluka kwa kuthamanga kwa mpweya.
2. Kuwongolera liwiro la fan ya condenser;
Njira yowongolera liwiro la mafani ndi njira yomwe yakhala ikukhwima kwa zaka zambiri. Zigawo zazikulu zamagetsi zomwe zimagwiritsidwa ntchito ndi ma frequency converters (magawo atatu) kapena ma speed governors (magawo amodzi).
Mfundo yaikulu yogwirira ntchito ndi kudzera mu chitsanzo cha mayankho a kuthamanga kwa utsi (kutentha kozizira) (1 ~ 5V kapena 4-20ma).
Lowetsani ku chosinthira ma frequency (speed governor), chosinthira ma frequency chimatulutsa (0~50HZ) ku fan malinga ndi malo ake, ndipo chimazindikira momwe fan imagwirira ntchito mosinthasintha.
Koma nthawi zambiri mtengo wake umakhala wokwera kwambiri.
3. Gwiritsani ntchito chida choziziritsira mpweya kapena fani kuti muzitha kuyendetsa mpweya nthawi ndi nthawi;
Chigawo chachikulu ndi chipangizo chowongolera kuchuluka kwa mpweya chomwe chili ndi louvered air voliyumu. Mfundo yake ndikugwiritsa ntchito chida chowongolera mpweya chotchedwa piston chomwe chimayendetsedwa ndi refrigerant yamphamvu kwambiri. Chipangizo chowongolera ichi chimatha kupeza mphamvu yokhazikika yotulutsa utsi monga chowongolera liwiro la fan;
Chofunika kwambiri ndichakuti mphamvu yolowera ya valavu yowonjezera isasinthe kwambiri monga momwe fan imagwirira ntchito nthawi ndi nthawi.
Chipangizo chotchingira mpweya chikhoza kuyikidwa pamalo olowera mpweya kapena pamalo otulutsira mpweya;
4. Gwiritsani ntchito chipangizo chodzaza ndi condenser.
Mfundo yogwira ntchito ya chipangizo chodzaza ndi condenser ndikugwiritsa ntchito refrigerant yochulukirapo kuti muwonjezere mphamvu ya condenser.
Chipangizo chodzaza ndi condenser chimagwiritsidwa ntchito m'malo otentha kapena otentha kwambiri kutumiza madzi ambiri mufiriji kuchokera ku accumulator kupita ku condenser, ndipo chimagwiritsa ntchito refrigerant yowonjezera kuti iwonjezere mphamvu ya condensation ya dongosolo, kuti tipewe mphamvu ya condensation kukhala yotsika kwambiri pa kutentha kochepa. Cholakwika.
