Zigawo zinayi zazikuluzikulu zama firiji zamafakitale ndi kompresa, condenser, throttling element (ie valavu yokulitsa) ndi evaporator.
1. Compressor
Compressor ndi mphamvu ya firiji kuzungulira.Imayendetsedwa ndi mota ndipo imazungulira mosalekeza.Kuphatikiza pa kutulutsa nthunzi mu evaporator mu nthawi kuti asunge kutentha kochepa komanso kutsika kwapansi, kumapangitsanso kuthamanga ndi kutentha kwa nthunzi ya refrigerant kudzera kupsinjika, ndikupanga mikhalidwe yosinthira kutentha kwa nthunzi ya refrigerant kupita kumalo akunja achilengedwe.Ndiko kuti, kutentha kwapansi ndi kutsika kwa mpweya wa refrigerant kumapanikizidwa kumalo otentha kwambiri komanso kupanikizika kwambiri, kotero kuti mpweya wa refrigerant ukhoza kuchepetsedwa ndi kutentha kwabwino kapena madzi ngati malo ozizira.
2. Condenser
Condenser ndi zida zosinthira kutentha.Ntchito yake ndikugwiritsa ntchito njira yoziziritsira zachilengedwe (mpweya kapena madzi) kuti ichotse kutentha kwa kutentha kwambiri komanso kuthamanga kwambiri kwa refrigeration nthunzi ya self cooling compressor, kuti kuziziritsa ndikuchepetsa kutentha kwambiri komanso kuthamanga kwambiri. refrigerant nthunzi mu refrigerant madzi ndi kuthamanga ndi kutentha yachibadwa.Ndikoyenera kutchula kuti posintha nthunzi ya refrigerant kukhala madzi a refrigerant, kukakamiza kwa condenser kumakhalabe kosasinthika ndipo kukadali kuthamanga kwambiri.
3. Chinthu chogwedeza (mwachitsanzo valavu yowonjezera)
The refrigerant madzi ndi kuthamanga kwambiri ndi kutentha yachibadwa mwachindunji anatumiza kwa otsika kutentha lonse evaporator.Malinga ndi mfundo ya machulukitsidwe kuthamanga ndi machulukitsidwe kutentha - makalata, kuchepetsa kuthamanga kwa madzi refrigerant, kuti muchepetse kutentha kwa refrigerant madzi.The refrigerant madzi ndi kuthamanga ndi kutentha yachibadwa anadutsa mavuto kuchepetsa chipangizo throttling chinthu kupeza refrigerant ndi otsika kutentha ndi otsika kuthamanga, ndiyeno anatumiza kwa evaporator kwa endothermic evaporation.Machubu a capillary nthawi zambiri amagwiritsidwa ntchito ngati zinthu zopumira m'mafiriji ndi ma air conditioner m'moyo watsiku ndi tsiku.
4. Evaporator
Evaporator ndi chipangizo chosinthira kutentha.The throttled otsika kutentha ndi otsika-anzanu refrigerant madzi ukuphwera (zithupsa) mu nthunzi, zimatenga kutentha kwa utakhazikika zakuthupi, amachepetsa zinthu kutentha, ndi kukwaniritsa cholinga kuzizira ndi refrigerating chakudya.Mu air conditioner, mpweya wozungulira umakhazikika kuti uziziziritsa ndi kuchepetsa mpweya.Kutsika kwa kutentha kwa mpweya wa refrigerant mu evaporator, kumachepetsa kutentha kwa chinthu kuti chizizizira.Mufiriji, kutentha kwa mpweya mufiriji wamba kumasinthidwa pa -26 C ~-20 C, ndipo kumasinthidwa kukhala 5 C ~8 C mu air conditioner.
