Yintoni iihydrocarbons (HCs)

IiHydrocarbons (HCs) zizinto ezenziwe ngeeathom zehydrogen ezidityaniswe kwiiathom zekhabhoni. Imizekelo yi-methane (CH4), ipropane (C3H8), ipropene (C3H6, eyaziwa ngokuba yipropylene) kunye ne-butane (C4H10).

Zonke ezi zinto zinokutsha kwaye azinatyhefu ngokohlelo lokhuseleko lwe-ASHRAE 34: udidi lwazo lokhuseleko yi-A3, kunye no-“A” othetha “ityhefu ephantsi” kunye no-“3” ethetha “ukutsha okuphezulu”.

 

 

Izinto eziluncedo kwiiHCs njengezikhenkcisi

Zintathu iingenelo eziphambili:

Amandla asezantsi okufudumala kwehlabathi

IiHCs zinesakhono esisezantsi sokufudumala kwehlabathi, Ke inceda ekunciphiseni iCO₂izinto ezikhutshwayo ukuba sisebenzisa iihydrocarbons njengefriji.

Ngokufanelekileyo isuka kwindalo

IiHCs zitsalwa emhlabeni, kunye neoli. Ugcino lwabo eMhlabeni lukhulu. Kwaye kulungele ukucofa kubo, ngokunjalo, ixabiso labo liphantsi kunelezinye iifriji zokwenziwa.

Ukusebenza ngcono kwefriji

 IiHCs zisebenza ngokufanelekileyo ngakumbi ukupholisa / ukufudumeza njengefriji kunezinye. Ngapha koko, ubushushu bazo obufihlakeleyo bomphunga bude buphindeke kabini kunezinye iifriji zokwenziwa, okuthetha ukupholisa okuphezulu/ukufudumeza kwesiphumo sokuhamba kobunzima obufanayo.

 Ukuphuculwa kokusebenza kakuhle kwamandla

Uphononongo olungumzekelo lubonisa ukuba ukufuduka ukusuka kwi-HFC R404A ukuya kwifriji yendalo eyi-R290, ngokomndilili, kunokuvumela ukuya kutsho kwi-10 lepesenti yokuphucula ukonga amandla.

Ulawulo olungcono lobushushu ngokuthanda icompressor

Ngokuhambelana neefriji zendalo, kukho imixube emitsha yokwenziwa ekhoyo kwimarike kunye ne-GWP ephantsi, eyaziwa ngokuba yi-A2Ls. Itheyibhile (ekumfanekiso) ibonisa eyona ndlela iphambili ekufuneka ithathelwe ingqalelo xa kufikelelwa kwisigqibo. Enye yale migaqo yinkqubo ye-thermal, engcono kwiifriji zendalo, oku kuthetha ukuba ayitshisi i-compressor njenge-A2Ls. Lo mba unegalelo ekusebenzeni kwamandla kunye nokuthembeka kwecompressor.
