Manyan abubuwa guda hudu na tsarin firiji na masana'antu sune compressor, condenser, throttling element (watau bawul ɗin faɗaɗa) da mai fitar da iska.
1. Compressor
Compressor shine ikon sake zagayowar firiji.Motar ne ke tafiyar da shi kuma yana jujjuyawa akai-akai.Bugu da ƙari, fitar da tururi a cikin evaporator a cikin lokaci don kula da ƙananan zafin jiki da ƙananan matsa lamba, yana kuma inganta matsi da zafin jiki na refrigerant ta hanyar matsawa, samar da yanayi don canja wurin zafi na refrigerant tururi zuwa matsakaicin muhalli na waje.Wato, tururin sanyi mai ƙarancin zafi da ƙarancin matsa lamba yana matsawa zuwa yanayin zafi mai zafi da matsa lamba, ta yadda za a iya murƙushe tururi mai sanyi da iska ko ruwa na al'ada a matsayin matsakaicin sanyaya.
2. Condenser
Condenser kayan aikin musayar zafi ne.Ayyukansa shine yin amfani da matsakaicin sanyaya muhalli (iska ko ruwa) don kawar da zafin tururi mai zafi da matsananciyar firji na kwampresar sanyaya kai, ta yadda za a yi sanyi da kuma takura yanayin zafi da matsananciyar matsa lamba. refrigeant tururi a cikin wani refrigerant ruwa tare da babban matsa lamba da al'ada zazzabi.Yana da kyau a ambaci cewa yayin da ake canza tururin refrigerant zuwa ruwa mai sanyi, matsa lamba na na'urar ya kasance ba canzawa kuma har yanzu yana da matsa lamba.
3. Abun maƙarƙashiya (watau bawul ɗin haɓakawa)
Ruwan firji tare da babban matsa lamba da zafin jiki na al'ada ana aika kai tsaye zuwa ma'aunin ma'aunin zafi mai ƙarancin zafi.Bisa ga ka'idar jikewa da zafin jiki - rubutu, rage matsa lamba na ruwa mai sanyi, don rage yawan zafin jiki na ruwa mai sanyi.Ruwan mai sanyaya tare da babban matsa lamba da zafin jiki na al'ada yana wucewa ta hanyar rage matsa lamba na na'urar da za a iya samun na'urar mai sanyi tare da ƙananan zafin jiki da ƙarancin matsa lamba, sannan a aika zuwa mai fitar da ruwa don fitar da endothermic evaporation.Yawancin lokaci ana amfani da bututun capillary azaman abubuwa masu fashewa a cikin firiji da kwandishan a rayuwar yau da kullun.
4. Evaporator
Shi ma mai fitar da iska na'urar musayar zafi ne.Ruwan sanyi mai ƙarancin zafi da ƙarancin matsa lamba yana ƙafe (yana tafasa) cikin tururi, yana ɗaukar zafin kayan da aka sanyaya, yana rage zafin kayan, kuma ya cimma manufar daskarewa da sanyaya abinci.A cikin na'urar kwandishan, ana sanyaya iskar da ke kewaye don sanyaya da kuma kawar da iska.Rage yawan zafin jiki na refrigerant a cikin evaporator, ƙananan zafin abin da za a sanyaya.A cikin firiji, ana daidaita yawan zafin jiki na refrigerant na gabaɗaya a -26 C ~ -20 C, kuma an daidaita shi zuwa 5 C ~ 8 C a cikin kwandishan.
