Ilimin damfara na firiji

1. Me yasa damfara (compressor) dole ne ta ci gaba da aiki na akalla mintuna 5 sannan ta tsaya na akalla mintuna 3 bayan ta kashe kafin ta sake farawa?

Tsayawa na akalla mintuna 3 bayan kashewa kafin sake kunnawa yana nufin kawar da bambancin matsin lamba tsakanin shigarwar compressor da sharar gida. Domin idan bambancin matsin lamba ya yi yawa, karfin farawa na injin zai karu, wanda hakan zai sa wutar lantarki ta tashi zuwa wani mataki, za a kunna mai kariya, kuma compressor ba zai iya ci gaba da aiki ba.

2. Tabbatar da matsayin wurin da aka sanya sinadarin fluorine mai cike da na'urar sanyaya daki

Galibi ana iya ƙara firiji a wurare uku: condenser, ɓangaren ajiyar ruwa na compressor, da kuma evaporator.

Lokacin da ake ƙara ruwa a wurin ajiyar ruwa, lokacin da tsarin ya fara aiki, injin sanyaya ruwa zai ci gaba da yin tasiri ga silinda, wanda hakan zai sa injin sanyaya ruwa ya haifar da girgizar ruwa, wanda hakan ke da matuƙar illa ga lalacewar injin sanyaya ruwa. A lokaci guda, bayan injin sanyaya ruwa ya shiga cikin injin sanyaya ruwa kai tsaye, yana iya mannewa da tashar, yana haifar da rufin da ba shi da ƙarfi da kuma rashin ƙarfin lantarki mai ƙarfi; haka nan, wannan yanayin zai kuma faru lokacin da ake ƙara ruwa a gefen injin sanyaya ruwa.

Dangane da na'urar sanyaya daki, saboda girmanta, tana iya adana isasshen ruwan sanyaya, kuma ba za a sami wata illa ba lokacin farawa, kuma saurin cikawa yana da sauri kuma amintacce; don haka galibi ana amfani da hanyar cike ruwa a na'urar sanyaya daki.

3.. Maɓallan zafi da na'urorin thermistor don canza mita

Maɓallan zafi da na'urorin thermistors ba su da alaƙa da wayoyi masu compressor kuma ba a haɗa su kai tsaye a jere a cikin da'irar compressor.

Makullan zafi suna sarrafa kunnawa da kashe da'irar sarrafa compressor ta hanyar jin zafin murfin compressor.

Thermistors abubuwa ne masu halayyar zafin jiki marasa kyau waɗanda ke da siginar amsawa zuwa ga microprocessor. An riga an shigar da saitin teburin zafin jiki da juriya a cikin microprocessor. Kowane ƙimar juriya da aka auna zai iya nuna yanayin zafi da ya dace a cikin microcomputer. A ƙarshe, ana cimma tasirin sarrafa zafin jiki.

4. Zafin jiki mai lanƙwasa na injin

Yanayin aiki ya kamata ya kasance ƙasa da 127°C a matsakaicin kaya.
Hanyar aunawa: Cikin daƙiƙa 3 bayan daƙiƙa 3 bayan damfarar ta tsaya, yi amfani da gadar Wheatstone ko ohmmeter na dijital don auna babban juriyar lanƙwasa, sannan a lissafta bisa ga dabarar da ke ƙasa:

Zafin juyawa t℃ = [R2(T1+234.5)/R1] -234.5

R2: juriyar da aka auna; R1: juriyar lanƙwasa a yanayin sanyi; T1: zafin motar sanyi

Idan zafin murɗawa ya wuce yanayin amfani, waɗannan lahani na iya faruwa:

Saurin tsufa na wayar da aka yi wa enamela yana ƙaruwa (motar tana ƙonewa);

Saurin tsufa na wayar ɗaure kayan rufi da takardar rufi yana ƙaruwa (an rage tsawon rayuwar rufi idan aka kwatanta da kowace ƙaruwar zafin jiki na 10℃);

Lalacewar mai saboda yawan zafi (ƙarfin shafawa yana raguwa)
