Chiyambi cha mawonekedwe a mufiriji wofulumira

Firiji yofulumira imakhala ndi magawo asanu motsatizana: kompresa, condenser, evaporator, fyuluta yowuma, ndi valavu yokulirapo.Kuchuluka kwa refrigerant kumalowetsedwamo, ndipo chipangizo chamagetsi chimayendetsa ntchito ya compressor malinga ndi zosowa za chilengedwe kuti zikwaniritse firiji ndi kutentha kutentha.cholinga cha.

kompresa

Makina amadzimadzi oyendetsedwa omwe amakweza mpweya wochepa kwambiri mpaka kuthamanga kwambiri.Mufiriji wofulumira ndiye mtima wa firiji.Imakoka mpweya wozizira kwambiri komanso wochepa mphamvu kuchokera ku chitoliro choyamwa, imayendetsa pisitoni kuti ikakanikize kupyolera mu kayendetsedwe ka galimoto, ndipo imatulutsa mpweya wotentha kwambiri komanso wothamanga kwambiri ku chitoliro chotulutsa mphamvu kuti ipereke mphamvu ya firiji. kuzungulira.Mwanjira iyi, kusinthasintha kwa firiji kwa kuponderezana → condensation → kukula → evaporation (mayamwidwe kutentha) kumachitika.

condenser

Mpweya wotentha kwambiri komanso wothamanga kwambiri wa refrigerant womwe umatuluka mu kompresa umatsitsidwa mufiriji yamadzimadzi kudzera mu kutha kwa kutentha, ndipo kutentha komwe kumatengedwa ndi refrigerant kuchokera ku evaporator kumatengedwa ndi sing'anga (mlengalenga) mozungulira condenser.

Evaporator

Refrigerant yamadzimadzi imasinthidwa kukhala mpweya wa mpweya pano.

zowumitsa zosefera

Mu firiji dongosolo, ntchito ya fyuluta youma ndi kuyamwa chinyezi mu firiji dongosolo, kutsekereza zonyansa mu dongosolo kuti asadutse, ndi kuteteza kutsekeka kwa madzi oundana ndi zonyansa blockage mu firiji dongosolo payipi.Popeza capillary (kapena valavu yowonjezera) ndi gawo lotsekedwa mosavuta la dongosolo, fyuluta youma nthawi zambiri imayikidwa pakati pa condenser ndi capillary (kapena valavu yowonjezera).

Valve yowonjezera yowonjezera

Kupondereza ndi kupsinjika kwa refrigerant yapamwamba kwambiri yamadzimadzi kuchokera ku chowumitsira madzi, kusintha ndikuwongolera kuchuluka kwa refrigerant yomwe imalowa mu evaporator, kuti igwirizane ndi kusintha kwa firiji, ndipo nthawi yomweyo kupewa nyundo yamadzimadzi. kompresa ndi nthunzi potulukira wa evaporator Kutentha kwachilendo.
