+/-5 ndi -25 ℃ Zozizira zazikulu komanso zapakati

Mafiriji akuluakulu ndi apakatikati angagwiritsidwe ntchito m'makampani a chakudya, mafakitale a mkaka, malo osungiramo masamba ndi zipatso, malo osungira mazira, asilikali, ndi zina zotero. Chinsinsi cha kusungirako kuzizira kwa chakudya ndikusungirako kutentha kwa zinthu za mkaka, nyama, nsomba, nkhuku, masamba ndi zipatso, chakudya chozizira, maluwa ophika, zomera zobiriwira, masamba a tiyi ndi zakudya zina.

Mu unsembe waukulu ndi sing'anga-kakulidwe ozizira storages, mayunitsi refrigeration ntchito refrigerate, ntchito madzi ndi otsika kwambiri vaporization kutentha monga madzi ozizira kuti volatilize pansi muyeso wa pansi kuthamanga ndi makina ntchito zida, kugaya ndi kuyamwa kutentha kwaiye posungira, ndiyeno kupitirira madzi Cholinga cha kuzirala pansi. Chofala kwambiri ndi firiji yamtundu wa shrink, yomwe imakhala ndi firiji compressor, ozizira, ndi volatilization chubu.

Malinga ndi njira ya zida za volatilization chubu, zimagawidwa m'mitundu iwiri: kuzirala kwamadzi nthawi yomweyo komanso kuzirala kwamadzi kosavuta. Ikani chubu cha volatilization m'chipinda chosungiramo chozizira kuti madzi azizizira nthawi yomweyo. Pamene madzi ozizira ozizira amadutsa pansi kuthamanga volatilization chubu, nthawi yomweyo digests ndi kuyamwa kutentha kwaiye mu nyumba yosungiramo katundu kuchepetsa kutentha. Mu kuzirala kosavuta kwamadzi, chowombera chowombera chimayamwa gasi mnyumba yosungiramo zinthu mu zida zoziziritsira mpweya. Mpweyawo ukadzazunguliridwa mu chubu cha evaporating m'zida zoziziritsira madzi, umatumizidwa kumalo osungiramo katundu kuti muchepetse kutentha. Ubwino wa njira yoziziritsira evaporative ndikuti madzi amazizira mwachangu ndipo kutentha kwa malo osungirako kumakhala kofanana. Pamodzi, imatha kuchita zinthu zovulaza monga CO2 zomwe zimayambitsidwa ndi njira yonse yosungira.

Malo osungiramo zinthu zazikulu ndi zapakati pachisanu amagawidwa m'magulu a L, Q, ndi J. Mitundu ingapo ya kutentha yomwe imagwiritsidwa ntchito kwambiri ndi 5--5C, -10 -18c, -20--23C, ndipo malo osungiramo mazira apadera amafika pansi -30C. Zosowa zosiyanasiyana zingaganizidwe. Ndi malo abwino ozizira ozizira osungiramo nyama, zam'madzi, mazira, mkaka, zipatso, ndiwo zamasamba ndi zipatso, ndi zina zotero. Nthawi zambiri zimagwira ntchito ku mabanki akuluakulu ndi mayunitsi. Ndiwokonda zachilengedwe komanso yopulumutsa mphamvu, ndipo mufiriji amakhala ndi ntchito yabwino kwambiri yotchinjiriza kutentha. Itha kutulutsa mitundu yosiyanasiyana ndi mitundu yafiriji kuti ipereke zosankha, zomwe ndi zabwino kwa makasitomala kugwiritsa ntchito malo omwe alipo komanso malo amkati mosinthika.

Momwe mungasankhire zida zamafiriji zosungirako zozizira kwambiri?

Palinso mitundu yambiri ya mafiriji. Mafiriji ambiri m'zipinda zazikulu zozizira zozizira kwambiri amakonda kugwiritsa ntchito mayunitsi ofanana. Ubwino wake ndi wotani?

1. Makanema odziwika padziko lonse lapansi a Bitzer refrigeration compressor ali ndi mawonekedwe okhazikika komanso phokoso lochepa poyerekeza ndi zinthu zina zofananira.

2. Kudalirika kwa ntchito ndikokwera kwambiri. Ngakhale compressor iliyonse ya firiji ikalephera, sizingakhudze magwiridwe antchito onse a firiji.

3. Pali mitundu yambiri ya mphamvu yozizirira. Kugula kosungirako kozizira kocheperako kapena kusinthasintha kwa kutentha nthawi zina kumatha kukhala kwakukulu, ndipo mayunitsi ofananira amatha kupeza chiyerekezo chabwinoko cha kuzizirira.

4. Compressor imodzi mu unit ili ndi katundu wocheperako wa 25%, ndipo ikhoza kusinthidwa kwa 50%, 75%, ndi 100% mphamvu, yomwe ingagwirizane ndi mphamvu yoziziritsa yomwe ikufunika pakugwira ntchito panopa kwambiri, ndipo imakhala yothandiza kwambiri komanso yopulumutsa mphamvu.

5. Compressor ili ndi mawonekedwe osavuta komanso ophatikizika, mphamvu yopondereza kwambiri komanso magwiridwe antchito apamwamba a firiji.

6. Mapaipi ofananira ndi ma valve amakhazikitsidwa pakati pa machitidwe awiri odziyimira pawokha. Pamene firiji unit ndi zipangizo zipangizo pa condenser akulephera, dongosolo lina akhoza kusunga ntchito yake yaikulu.

7. The unit control ndi advanced PLC electronic control and display functio
