Imigaqo yokukhetha i-compressor yefriji
1) umthamo wokupholisa wecompressor kufuneka ukwazi ukuhlangabezana neemfuno zomthwalo ophezulu wexesha lokuvelisa indawo ebandayo, oko kukuthi, umthamo wokupholisa wecompressor kufuneka ube mkhulu okanye ulingane nomthwalo woomatshini. Ngokubanzi ekukhetheni icompressor, ngokwexesha elishushu lonyaka lobushushu bamanzi okupholisa (okanye ubushushu) ukuze kuchongwe ubushushu bokujiya, ubushushu bokujiya kunye nobushushu bokufuma ukuze kuchongwe iimeko zokusebenza kwecompressor. Nangona kunjalo, umthwalo ophezulu wemveliso yokugcina indawo ebandayo awusoloko ukwixesha lobushushu eliphezulu, ubushushu bamanzi okupholisa ekwindla, ebusika nasentwasahlobo (ubushushu) buphantsi kakhulu (ngaphandle kwamanzi anzulu), ubushushu bokujiya buyancipha, umthamo wokupholisa wecompressor uya kwanda. Ke ngoko, ukhetho lwecompressor kufuneka luqwalasele into yokulungisa ixesha lonyaka.
2) Kwindawo yokugcina izinto ezibandayo ezincinci, ezifana nendawo yokugcina izinto ezibandayo ubomi bonke, i-compressor ingakhethwa njengeyunithi enye. Kwindawo yokugcina izinto ezibandayo enomthamo omkhulu kunye nendawo enkulu yokucubungula izinto ezibandayo kwigumbi lokukhenkceza, inani leeyunithi ze-compressor akufuneki libe ngaphantsi kwezibini. Umthamo opheleleyo wefriji ukuhlangabezana neemfuno zemveliso uya kuphumelela, kwaye ngokubanzi awucingi ngokulinda.
3) uthotho lwe-compressor yefriji akufuneki ludlule ezimbini, njengee-compressor ezimbini kuphela, uthotho olufanayo kufuneka lukhethwe ukuze kube lula ukulawula, ulawulo kunye nokutshintshana kwezixhobo ezingasetyenziswanga.
4) kwiinkqubo ezahlukeneyo zobushushu bokufuma ezixhotyiswe ngeecompressors, kufuneka kuqwalaselwe ngokufanelekileyo ukuba kunokwenzeka ukuba kubekho ukugcinwa kwe-backup phakathi kweeyunithi.
5) Ukuba i-compressor enesixhobo esilawula amandla, inokwenza uhlengahlengiso olukhulu kumthamo wokupholisa womatshini omnye, kodwa ilungelelaniswe kuphela nokusebenza kokuguquguquka komthwalo kummiselo, akufuneki isetyenziswe kutshintsho lomthwalo wexesha elithile kummiselo. Utshintsho lomthwalo wexesha elithile okanye umthamo wemveliso kummiselo womthwalo, kufuneka lucwangciswe ngokwahlukeneyo ngomthamo wokupholisa womatshini, ukuze kufezekiswe isiphumo esingcono sokonga amandla.
6) Ukuze kuhlangatyezwane neemfuno zenkqubo yemveliso, umjikelo wokukhenkceza udla ngokufuneka ukuze kufunyanwe ubushushu obuphantsi bokufuma, ukuze kuphuculwe i-coefficient yokuhanjiswa kwe-compressor kunye nokusebenza kakuhle okubonisiweyo, ukukhusela ukhuseleko lokusebenza kwe-compressor, kufuneka kusetyenziswe umjikelo wokukhenkceza woxinzelelo lwezigaba ezibini. Umlinganiselo woxinzelelo lwenkqubo yokukhenkceza i-Ammonia i-Pk/P0 mkhulu kune-8 xa kusetyenziswa ucinezelo lwezigaba ezibini; Umlinganiselo woxinzelelo lwenkqubo yeFreon i-Pk/P0 mkhulu kune-10, ukusetyenziswa kocinezelo lwezigaba ezibini.
7) Iimeko zokusebenza ze-compressor yefriji, akufuneki zidlule iimeko zokusebenza ezinikiweyo ngumvelisi okanye imigangatho yesizwe yokusebenzisa iimeko ze-compressor.
Imigaqo ngokubanzi yokukhetha i-condenser
I-Condenser yenye yezona zixhobo ziphambili zokudlulisa ubushushu kwinkqubo yokukhenkcisa. Kukho iintlobo ezininzi zee-condenser, eyona nto iphambili ekukhetheni ubushushu bamanzi, umgangatho wamanzi, amanzi kunye neemeko zemozulu kwindawo yokwakha ithala leencwadi, kodwa kwakhona noyilo lweemfuno zegumbi, ngokubanzi ngokwemigaqo elandelayo yokukhetha.
1) Ii-condenser ezipholisiweyo ngamanzi ngokuthe nkqo zifanelekile kwiindawo ezinemithombo yamanzi emininzi, umgangatho wamanzi ophantsi kunye nobushushu bamanzi obuphezulu, kwaye zihlala zibekwe ngaphandle kwegumbi lomatshini.
2) Ii-condenser ezipholisiweyo ngamanzi ezithe tye zifanelekile kwiindawo ezinamanzi aneleyo, umgangatho wamanzi olungileyo kunye nobushushu bamanzi obuphantsi, kwaye zisetyenziswa kakhulu kwiinkqubo ze-ammonia ezincinci neziphakathi kunye neenkqubo zeFreon, kwaye zihlala zibekwe kwigumbi lezixhobo kwigumbi lomatshini.
3) Ii-condenser ezipholisiweyo ngamanzi zifanelekile kwiindawo ezinobushushu obuphantsi bebhalbhu emanzi, ukunqongophala kwamanzi okanye umgangatho wamanzi ophantsi, kwaye zihlala zibekwe kwindawo engaphandle enomoya opholileyo.
4) I-evaporative condenser ifanelekile kwiindawo ezinomswakama ophantsi kunye neendawo zokunqongophala kwamanzi, kwaye idla ngokufumaneka kwindawo engaphandle enomoya ococekileyo.
5) I-condenser epholisiweyo ngomoya ifanelekile kwiindawo ezinamanzi amaninzi kunye nenkqubo yokupholishwa encinci yeFreon. Ngokuqhelekileyo ayisetyenziswa kwiinkqubo zokupholishwa kwe-ammonia.
Ukongeza, phantsi kwemeko yokuhlangabezana neemfuno zenkqubo, izinto ezinje ngokuphucula ukusebenza kakuhle kokudluliselwa kobushushu, ukwenza lula ukugcinwa kunye nokunciphisa utyalo-mali lokuqala kwizixhobo kufuneka ziqwalaselwe.
Ukukhethwa kwemigaqo ngokubanzi kwezixhobo zokupholisa
Izixhobo zokupholisa zikwinkqubo yokukhenkcisa ukuze zivelise isiphumo sokubanda sezixhobo zokudlulisa ubushushu eziphantsi kobushushu obuphantsi, ezisebenzisa ulwelo lwefriji ngokuthomalalisa ivalvu ekupholiseni kobushushu obuphantsi, zifunxa ubushushu besixhobo esipholileyo (njengetyuwa, umoya), ukuze ubushushu besixhobo esipholileyo buncitshiswe.
Ukukhethwa kwezixhobo zokupholisa kufuneka kumiselwe ngokweemfuno zokucubungula ukutya okubandayo, ukukhenkceza okanye ezinye iinkqubo, kwaye ngokubanzi kufuneka kukhethwe ngokwemigaqo elandelayo.
1) ukusetyenziswa kwezixhobo zokupholisa ezikhethiweyo kunye neemeko zobugcisa kufuneka kuhambelane neemfuno ezisemgangathweni zangoku zezixhobo zokupholisa zeeyunithi zokukhenkcisa.
2) igumbi lokupholisa, igumbi lokukhenkceza kunye nezixhobo zokupholisa kwigumbi lokupholisa kufuneka zisetyenziswe kwifeni yokupholisa.
3) izixhobo zokupholisa kwigumbi lefriji zingakhethwa kwi-exhaust ephezulu, i-exhaust eludongeni nakwi-chiller. Ngokubanzi xa ukutya kunepakethe elungileyo, kufanelekile ukusebenzisa i-chiller; ukutya ngaphandle kwepakethe elungileyo, kunokusetyenziswa i-exhaust ephezulu, i-exhaust eludongeni.
4) ngokweemfuno ezahlukeneyo zenkqubo yokuqandisa ukutya ukukhetha izixhobo ezifanelekileyo zokuqandisa, ezinje ngokuqandisa itonela, isixhobo sokuqandisa esisicaba esingaphambili, isixhobo sokuqandisa ulwelo kunye nesixhobo sokuqandisa umbhobho wohlobo lweshelufu.
5) Izixhobo zokupholisa kwigumbi lokupakisha kwiqondo lobushushu legumbi elingaphezulu kwe -5 ℃ kufuneka zisetyenziswe xa kuphola, ubushushu begumbi obungaphantsi kwe -59 ℃ kufuneka busetyenziswe xa kuphola umqolo wemibhobho.
6) igumbi lokugcina umkhenkce kusetyenziswa umbhobho ogudileyo ongaphezulu.
