Chiller

Kwimizi-mveliso yefriji, yahlulwe ngokwezikhenkcezi-moya ezipholileyo kunye nezikhenkcezisi ezipholiswe ngamanzi.Ngokwecompressor, yahlulwe yaba zi-screw chillers, scroll chillers, kunye ne-centrifugal chillers.Ngokubhekiselele kulawulo lobushushu, yahlulwe kwi-chiller yeshishini eliphantsi lobushushu kunye ne-chiller eqhelekileyo yobushushu.Ubushushu beyunithi yobushushu obuqhelekileyo bulawulwa ngokubanzi ngaphakathi kwinqanaba le-0 ukuya kuma-35 degrees.Ulawulo lobushushu beyunithi yobushushu obuphantsi ngokuqhelekileyo bujikeleze i-0 degrees ukuya kwi-100 degrees.

I-Chillers zikwabizwa ngokuba: iifriji, iiyunithi zefriji, iiyunithi zamanzi e-ice, izixhobo zokupholisa, njl.Umgaqo wayo wokusebenza ngumatshini oguquguqukayo osusa umphunga wolwelo ngoxinzelelo okanye ubushushu bomjikelo wefriji.

I-chiller iquka izinto ezine eziphambili: i-compressor, i-evaporator, i-condenser, kunye ne-valve yokwandisa, ngaloo ndlela iqonda isiphumo sokupholisa kunye nokufudumeza kweyunithi.

Izibandisi zaziwa ngokuba ziifriji, iifriji, oomatshini bamanzi omkhenkce, oomatshini bamanzi abandayo, oomatshini bokupholisa, njl. Ngenxa yokuba isetyenziswa kakhulu kuzo zonke iinkalo zobomi, kukho amagama angenakubalwa.Ngophuhliso oluqhubekayo loshishino lwe-chiller, abantu abaninzi ngakumbi baqala ukunikela ingqalelo kwinto yokuba naluphi na ukhetho kwishishini le-chiller liba libaluleke ngakumbi nangakumbi ebantwini.Ngokwesakhiwo semveliso, "iiyunithi zokupholisa amanzi ezipholileyo ezinomlinganiselo ophezulu wokusebenza kakuhle kwamandla", "iiyunithi zempompo yobushushu bomthombo wamanzi", "Iyunithi yokubuyisela ubushushu beScrew", "iyunithi yempompo yobushushu esebenza kakuhle", "iyunithi yesikhenkcezisi se-scrycryogenic" kunye ngoko ke bakhuphisana kakhulu.Umgaqo wobume bayo ngumatshini osebenza ngezinto ezininzi osusa umphunga wolwelo ngoxinzelelo okanye ubushushu bomjikelo wefriji.I-chiller yokunyanzeliswa komphunga iquka izinto ezine eziphambili: i-compressor, i-evaporator, i-condenser, kunye nesixhobo sokulinganisa i-metering, esiphumeza izikhenkcezisi ezahlukeneyo ngendlela yomjikelo wokunyanzeliswa komphunga.I-Absorption chillers isebenzisa amanzi njengefriji, kwaye ithembele kubudlelwane obuqinileyo phakathi kwamanzi kunye nesisombululo se-lithium bromide ukuphumeza umphumo wokupholisa.Ii-Chillers ziqhele ukusetyenziswa kwiiyunithi zokupholisa umoya kunye nokupholisa kwamashishini.Kwiinkqubo zokupholisa umoya, amanzi abandayo adla ngokusasazwa kwizitshintshi zobushushu okanye iikhoyili kwiiyunithi zokuphatha umoya okanye ezinye iintlobo zezixhobo zetheminali zokupholisa kwiindawo zazo, aze ke amanzi abandayo aphinde asasazwe kwakhona kwicondenser ukuze apholiswe.Kwizicelo zamashishini, amanzi abandayo okanye olunye ulwelo luyapholiswa ngokumpompa ngenkqubo okanye izixhobo zelabhoratri.I-industrial chillers isetyenziswa kumashishini ahlukeneyo ukulawula ukupholisa kweemveliso, izixhobo kunye noomatshini befektri.Ii-chillers zinokwahlulwa ngokubanzi zibe ngamanzi-apholise kwaye apholile ngomoya ngokwendlela yokupholisa.Ngokobuchwephesha, umlinganiselo wokusetyenziswa kwamandla ombane opholileyo wamanzi ngu-300 ukuya kwi-500 kcal / h ngaphezu kwe-air-cooled;ngokofakelo, iinqaba zokupholisa ezipholileyo zingasetyenziswa.Ukupholisa umoya kuyasuswa ngaphandle kolunye uncedo.
