4.3 Iimpawu zokuLungiselela
Iicompressors zeDaming zihambelana nemeko yokusebenza eyahlukeneyo kunye neefriji, kwaye zinokwanelisa kakhulu iimfuno zakho zenkqubo yefriji.
Itekhnoloji ephuhlisiwe, i-compact dimension, umthamo omncinci kunye nendawo.
Ukuchaneka okuphezulu komatshini wokuqinisekisa ukuba icompressor iqinisekisa ngomgangatho, iziko lokusetyenzwa kwe-CNC, ukugxila ngenxa yetekhnoloji ethile yokusetyenzwa, indawo encinci yokufa.
Ukusebenza okuzinzileyo, ukungcangcazela okuncinci kunye nengxolo ephantsi, uzinzo olugqwesileyo.
Ifriji efana ne-R22 kunye ne-R404 zamkelwe ukukhusela okusingqongileyo, Kwisicelo sobushushu obuphakathi kunye nophantsi.
Isixhobo sokukhusela iimoto zombane, isivamvo sePTC.
Nxiba igiya yomqhubi ekwaziyo ukumelana, i-Chrome plated piston rings kunye ne-aluminiyam pistons, i-crank-shaft eqinileyo, iseti ephantsi yokukhuhlana.
Uyilo olusebenzayo lwepleyiti yevalvu, umthamo omkhulu wokukhenkceza kunye nokusetyenziswa kwamandla aphantsi, izinga loxinzelelo olusebenzayo, Ingcongolo yeValve eyenziwe ngentsimbi yasentwasahlobo exhathisayo ngaphandle.
Iindawo ezisecaleni ngokubanzi, ezilungele ukulungiswa.
