Za chiller unit

Chiller unit (yomwe imadziwikanso kuti firiji, unit ya refrigeration, ice water unit, kapena zida zoziziritsira) ndi mtundu wa zida zopangira firiji. Mu mafakitale a firiji, zozizira zimagawidwa m'magulu oziziritsidwa ndi mpweya komanso madzi. Kutengera kompresa, amagawidwanso kukhala screw, scroll, ndi centrifugal chillers. Pankhani ya kuwongolera kutentha, amagawidwa m'mafakitale otsika kutentha komanso oziziritsa kutentha. Kuzizira kozizira bwino nthawi zambiri kumayang'aniridwa mkati mwa 0 ° C mpaka 35 ° C, pomwe zozizira zotsika nthawi zambiri zimayendetsedwa mkati mwa 0 ° C mpaka -100 ° C.

Zozizira nthawi zambiri zimagawidwa m'njira zoziziritsa ngati zoziziritsidwa ndi madzi kapena zoziziritsidwa ndi mpweya. Mwaukadaulo, kuziziritsa kwamadzi kumapereka 300 mpaka 500 kcal / h kuposa kuzirala kwa mpweya.

Mpweya Woziziritsa Chiller
Mawonekedwe
1. Palibe nsanja yozizirira yomwe imafunikira, kukhazikitsa kosavuta ndi kusamutsa, yoyenera kugwiritsa ntchito komwe madzi akusowa.
2. Galimoto yamafani yaphokoso yotsika, yoziziritsa bwino komanso yokometsera, kachipangizo kokhazikika, komanso kuletsa dzimbiri.

Madzi ozizira ozizira
Mawonekedwe
1. Gulu lopangidwa ndi ergonomically, kuwongolera kokhazikika, komanso kuwongolera kutentha kwamagetsi kumatsimikizira kugwira ntchito kwanthawi yayitali.
2. Zotenthetsera zamphamvu kwambiri zimachepetsa kuzizira, zimathandizira kuti mafuta abwerere, ndikuletsa machubu otengera kutentha kuti asaundane ndi kusweka.

Chozizira chozizira ndi madzi chimagwiritsa ntchito chipolopolo ndi chubu evaporator kusinthanitsa kutentha pakati pa madzi ndi firiji. Firiji ikatha kuyamwa kutentha m'madzi ndikuzizira madzi kuti apange madzi ozizira, kompresa imabweretsa kutentha ku chipolopolo ndi chubu condenser. Kutentha kwa refrigerant ndi madzi kuti madzi atenge kutentha ndikuchotsa kutentha kunja kwa nsanja yoziziritsa kunja kudzera m'mipope yamadzi kuti iwonongeke (kuzizira kwamadzi). Poyamba, kompresa imatenga mpweya wotentha kwambiri, wochepetsetsa wa refrigerant pambuyo pa evaporation ndi kuzizira, ndiyeno amaupaka mu mpweya wotentha kwambiri, wothamanga kwambiri ndikuutumiza ku condenser; mpweya wothamanga kwambiri, wotentha kwambiri umatsitsidwa ndi condenser ndikusungunula mumadzi otentha, othamanga kwambiri; pamene yachibadwa-kutentha, mkulu-anzanu madzi umayenda mu valavu matenthedwe kukula, ndi throttled mu otsika kutentha, otsika-anzanu chonyowa nthunzi ndi umayenda mu chipolopolo ndi chubu evaporator, kuyamwa kutentha kwa madzi ozizira mu evaporator kuchepetsa kutentha kwa madzi; refrigerant yamadzimadzi imayamwanso mu kompresa, ndipo mkombero wotsatira wa firiji umabwerezedwa.

Air-Cooled Screw Chiller
Mawonekedwe
1. Mpweya woziziritsa mpweya ndi mtundu wa fin, mafuta awiri opangidwa ndi hydrophilic aluminium platinamu. Amapangidwa pogwiritsa ntchito zida zaukadaulo zosinthira kutentha, amakhala ndi mawonekedwe ophatikizika, kukula kochepa, kulemera kopepuka, komanso kutentha kwakukulu. Ili ndi chowotcha chothamanga kwambiri, chamtundu waukulu wa axial flow, chomwe chimachepetsa phokoso lantchito komanso chilengedwe.
2. Dongosolo loyang'anira ma unit limagwiritsa ntchito chowongolera chopangidwa ndi PLC chotumizidwa kunja chokhala ndi chiwonetsero chachikulu chokhudza mawonekedwe osavuta komanso owoneka bwino.
3. Chigawochi chimakhala ndi zipangizo zodalirika zotetezera chitetezo, kuphatikizapo zotetezera zowonongeka kwambiri ndi zotsika, zotetezera kutentha kwa mpweya, compressor motor overheat protectors, overload current protectors, antifreeze kutentha otetezera, madzi otetezera madzi, masiwichi oyimitsa mwadzidzidzi, mapulagi a fusible osamva kutentha, ndi ma valve otetezera. Madzi Wozizira Screw Chiller

Mawonekedwe
1. Mapangidwe osavuta, kusinthana kwa kutentha kosasunthika, kugwira ntchito kwa nthawi yaitali, ndi kukonza kosavuta.
2. Dongosolo loyang'anira gululi limagwiritsa ntchito wolamulira wopangidwa ndi PLC wotumizidwa kunja, ndipo mawonekedwe a makina a anthu ali ndi mawonekedwe akuluakulu okhudza, omwe amapereka mawonekedwe osavuta komanso omveka bwino komanso osavuta.
