Siyini leso simiso esiyinhloko imbala ezivamile futhi uhlelo ifriji?

Ezweni lanamuhla Kunzima ukucabanga ngaphandle ipumelelo inqubekela kanye nokuthuthukisa impucuko kwezesayensi nakwezobuchwepheshe. Ngenxa yesayensi okutholakele abantu wenza izinhlobo ezahlukene iyatholakala energy esiza isintu namuhla. Enye yalezi ngempumelelo kwaba kokusungulwa ifriji iyunithi ngo-1910, i-physics French Marcel Odifrenom.

Umgomo we operation imbala esekelwe mkhuba ngokomzimba ka ukufingqa kanye ukuhwamuka, okuyinto waveza kanje: uhlelo impompi yokushisa ifriji idlulisela amandla ukushisa esuka egumbini sisebenzela ngaphandle, lapho epholisa futhi kwashabalala ku imvelo. I ukupholisa igesi okuyinto uba freon, nesibabule hexafluoride, i-ammonia, noma lucwaningo inqubo ephambene, lapho abandayo ikhiqizwa.

Ukufeza ukusebenza Ukupholisa okusezingeni eliphezulu liyadingeka endaweni enkulu Ukushisa lwaluyophola umzimba ukushisa ukuze bakwazi ukwakha umfutho ophakeme. Modern ifriji izinhlelo akusiyo njalo elula, ngakho lapha ukuze kuzuzwe edingekayo ingcindezi esetshenziswa compressors ukuthi cindezela bese ekhiphela refrigerant umusi, ngaleyo ndlela kwande hhayi kuphela ingcindezi kodwa futhi izinga lokushisa kwe-kokupholisayo. Ngakho, isimiso ukusebenza ohlelweni ifriji kusekelwe imithetho eyisisekelo physics.

Refrigeration compressors kukhona ezinye zezinhlobo ezilandelayo:

- Intulo;

- Piston;

- uhlobo centrifugal.

I yamuva ayizona ngempumelelo kakhulu futhi ezisetshenziswa kakhulu yesimanje ifriji izinhlelo nokuba angasetshenziswa ezimbonini. Ngaphezu kwalokho, kunoma iyiphi esiqandisini futhi efrijini ngempela kuhlanganisa capacitor okuhloswe ngalo ukuguqula umusi ku ketshezi ngenxa yezinguquko lokushisa kuma.

Ngokuvamile, isiqandisi isimiso ukusebenza alisetshenziswa kuphela ukukhiqiza ifriji izinjongo ezihlukile, kodwa izinhlelo okokuqandisa, kusukela ngokulungisa ingcindezi ohlelweni bengathola izinga lokushisa oyifunayo ngaphakathi imvelo ekamelweni. Lapho compressor sihamba refrigerant ngaphansi kwengcindezi okusezingeni eliphezulu ngokusebenzisa orifice akhethekile ingena egumbini vaporization, lapho kwaphumela abukhali ukwehla uketshezi kweso siguqulelwa umusi ingcindezi. Kulesi mkhuba ngokomzimba of the refrigerant ngenxa impahla yayo kuthatha ukushisa ezindongeni evaporator, kuphumele Ukupholisa kancane kancane ekamelweni sangaphakathi ifriji iyunithi.

Umgomo we operation imbala iye yasetshenziswa iminyaka engu-100, futhi njalo ngonyaka zikhona ukufakwa amaningi amasha futhi ngcono. Omunye ezisunguliwe zakamuva kulo mkhakha bekulokhu ukuvela thermoelectric ifriji amayunithi ezisebenzisa Peltier isimiso. Umthelela kusekelwe okuvela kuyo umehluko lokushisa medium lapho wamanje ageleza, lapho kungenzeka ukuba sifinyelele ukwehlisa izinga lokushisa zangaphakathi isikhala ifriji imvelo. Naphezu kweqiniso lokuthi abafundile kudala wathola impahla i kagesi, kuze kube muva nje okwandile ezitolo abandayo ezifana ayitholanga. Ngokuvamile ibekwa asetshenziswe yezimoto amafriji, Coolers futhi amanzi okuphuza isikhwama ezipholile, kodwa ngenxa izindleko aphezulu thermoelectric izakhi Ukupholisa injongo kuze kube muva nje kwakungenziwanga ngokwanele eqonda.

Modern isinyathelo esiqandisini isimiso ezongenza isicelo esiqandisini ezimbonini kanye amayunithi qa yokudla, kanye indawo ebanda luhlobo kanye agcine imikhiqizo. Kunzima overestimate ukubaluleka ukutholakala yomthetho wesibili wokushintsha kwamandla nokwakheka, ngoba ngaphandle kwalo ngeke zikwazi ukusebenzisa konke ukungenelela imisebenzi yesimanje okulungisa ukudla izitshalo. Ngakho, isimiso wokusebenza imbala namuhla wabeka isisekelo yesimanje Ukupholisa izinhlelo kokubili izinjongo ezimbonini nasemizini.
