1. Kutheni imozulu ibanda, kokukhona isiphumo sokufudumeza siba sibi? Impendulo: Isizathu esiphambili kukuba xa imozulu ibanda kwaye ubushushu bangaphandle buphantsi, kokukhona kunzima ukuba i-air conditioner ifunxe ubushushu bomoya obuvela kwindawo yomoya ongaphandle, nto leyo ebangela ukungcola...Funda ngokugqithisileyo -
Ii-screw friji compressors zisengozini...
Ii-screw friji compressors zii-volumetric compressors. Ekubeni bezisetyenziswa ukususela ngo-1934, ngenxa yokusebenza kwazo kakuhle, ukungagugi, kunye nomthamo omkhulu wokupholisa, ziye zalawula iinkqubo zefriji ezincinci ukuya kwezinkulu neziphakathi. Ngoko ke zeziphi iintlobo zokungaphumeleli ezinokuthi...Funda ngokugqithisileyo -
Umgaqo womjikelo wemigca emininzi kunye...
Icinezelwe yicompressor, igesi yokuqala yefriji enobushushu obuphantsi noboxinzelelo oluphantsi icinezelwa ibe ngumphunga oshushu kakhulu nobobushushu obuphezulu, ize emva koko ikhutshwe kumbhobho wokukhupha umoya wecompressor. Emva kokuba ifriji yegesi enobushushu obuphezulu noboxinzelelo oluphezulu isusiwe...Funda ngokugqithisileyo -
