Kuzizira: njira yogwiritsira ntchito gwero lotentha lotsika lomwe limapangidwa ndi firiji kuti liziziritse chinthucho kuchokera kutentha kwabwinobwino kenako nkuchizizira.
Kusunga mufiriji: Njira yogwiritsira ntchito kupeza gwero lotentha pang'ono pogwiritsa ntchito kuzizira komwe kumachitika chifukwa cha kusintha kwa momwe thupi la refrigerant lilili.
Mitundu ya zida zoziziritsira: kupanga zinthu zozizira (mufiriji), kuzizira kwa zinthu, kuziziritsa.
Njira zosungiramo firiji: mtundu wa pistoni, mtundu wa screw, gawo la compressor yoziziritsira ya centrifugal, gawo la mayamwidwe a firiji, gawo la mafiriji a nthunzi ndi nayitrogeni yamadzimadzi.
Njira yoziziritsira: yoziziritsidwa ndi mpweya, yolowetsedwa, komanso yoziziritsira kudzera mu chubu chachitsulo, khoma ndi chipangizo choziziritsira kutentha chokhudzana ndi zinthu.
ntchito:
1. Kuziziritsa, kuzisunga mufiriji komanso kuzinyamula m'firiji.
2. Kuziziritsa, kusungira zinthu zozizira, kusunga zinthu zozizira komanso kunyamula zinthu zaulimi ndi chakudya m'mlengalenga wowongoleredwa.
3. Kukonza chakudya, monga kuumitsa mufiriji, kuzizira kwambiri ndi kuziziritsa zinthu, ndi zina zotero.
4. Mpweya woziziritsa m'mafakitale opangira chakudya.
Mfundo Yoyendetsera Nthawi Yozizira
Zipangizo zazikulu: compressor yoziziritsira, condenser, valavu yowonjezera, evaporator.
Mfundo ya kayendedwe ka firiji: Pamene firiji imatenga kutentha mu mkhalidwe wa madzi otsika kutentha ndi otsika kuthamanga, imasanduka nthunzi yotsika kutentha ndi yotsika kuthamanga, ndipo firiji yomwe imasanduka nthunzi imakhala mpweya wotentha kwambiri komanso wokwera kuthamanga pansi pa mphamvu ya compressor, ndipo kutentha kwambiri ndi kuzizira kwambiri kumakhala madzi otsika kuthamanga, madzi okwera kuthamanga kwambiri. Imakhala madzi otsika kuthamanga kudzera mu valavu yowonjezera, kenako imatenga kutentha ndi kuzizira kachiwiri kuti ipange kayendedwe ka firiji.
Mfundo ndi Mfundo Zoyambira
Mphamvu ya firiji: Pazifukwa zina zogwirira ntchito (ndiko kuti, kutentha kwina kwa evaporation ya refrigerant, kutentha kwa condensation, ndi kutentha kwa subcooling), kutentha komwe refrigerant imatenga kuchokera ku chinthu chozizira pa nthawi iliyonse. Imadziwikanso kuti mphamvu yozizira ya refrigerant. Pazifukwa zomwezi, mphamvu ya refrigerant yoziziritsa ya refrigerant yomweyi imagwirizana ndi kukula, liwiro ndi magwiridwe antchito a compressor.
Kuziziritsa mwachindunji: Mu nthawi yoziziritsa, ngati evaporator yomwe firiji imayamwa kutentha imasinthasintha kutentha mwachindunji ndi chinthu chomwe chikufunika kuziziritsidwa kapena malo ozungulira chinthu chomwe chikufunika kuziziritsidwa. Nthawi zambiri imagwiritsidwa ntchito mu zida zoziziritsira zomwe zimafunikira kuziziritsidwa m'mafakitale, monga ayisikilimu firiji, malo osungiramo ozizira ang'onoang'ono komanso firiji yapakhomo.
Refrigerant: Chinthu chogwira ntchito chomwe chimazungulira mosalekeza mu chipangizo choziziritsira kuti chiziziziritsa. Chipangizo choziziritsira chopondereza nthunzi chimapangitsa kutentha kusamuka kudzera mu kusintha kwa momwe firiji imakhalira. Refrigerant ndi chinthu chofunikira kwambiri kuti chiziziziritsa chopangidwa.
Kuzizira mosalunjika: Gwiritsani ntchito zipangizo zotsika mtengo ngati zonyamulira kuti muzitha kusinthana kutentha pakati pa zipangizo zoziziritsira ndi malo kapena makina ozizira.
Refrigerant: Samutsani kuzizira komwe kumapangidwa mu evaporator ya refrigerant ya chipangizo choziziritsira ku kutentha komwe kumatengedwa ndi chinthu chomwe chiyenera kuziziritsidwa, kenako muzisamutsire ku refrigerant mutafika pa chipangizo choziziritsira, kenako muzizibwezeretsanso kuti zizizire.
Mfundo Yokhudza Kuzizira Kosalunjika
Mfundo yosungiramo zinthu zosalunjika: Madzi amchere akamayamwa mphamvu yozizira kuchokera mufiriji yomwe ili mu evaporator, amalowa m'malo osungiramo zinthu ozizira kudzera mu pampu yamadzi amchere, amasinthanitsa kutentha ndi chinthu chomwe chiyenera kuziziritsidwa kapena cholumikizira kuntchito kuti chiyamwitse kutentha, ndikubwerera ku evaporator kuti asinthe madzi omwe atengedwa. Kutentha kumasamutsidwira ku refrigerant, yomwe imadzibwezeretsanso kuti izizire.
