Chii chinonzi hydrocarbons (HCs)

MaHydrocarbons (HCs) zvinhu zvinoumbwa nemaatomu ehydrogen zvakabatanidzwa kumaatomu ecarbon. Mienzaniso ndeye methane (CH4), propane (C3H8), propene (C3H6, inozivikanwawo sepropylene) uye butane (C4H10).

Izvi zvese zvinopfuta uye zvisina chepfu zvinoenderana nechikamu chekuchengetedza cheASHRAE 34: kirasi yavo yekuchengetedza ndeye A3, ine "A" inoreva kuti "hupfu hwakadzika" uye "3" zvinoreva "kupisa kwakanyanya".

 

 

Zvakanakira zveHCs semafiriji

Pane zvitatu zvakakosha zvakanakira:

Kudzikira kwepasi kunogona kuitika

MaHC ane simba rakaderera rekudziya kwepasi rose, Saka zvinobatsira mukuderedza CO₂utsi kana tikashandisa mahydrocarbon sefiriji.

Zviri nyore zvakabva kune zvakasikwa

MaHC anotorwa kubva muvhu, zvakare pamwe chete nemafuta. Zvavakachengetera paNyika zvakakurisa. Uye zviri nyore kuvabaya, zvakare, mutengo wavo wakaderera pane wemamwe mafiriji ekugadzira.

Zvirinani kuita refrigerant

 MaHC anoshanda zvakanyanya kutonhora / kupisa sefiriji kupfuura mamwe. Muchokwadi, kupisa kwavo kwakadzikama kwemhepo kunokwira zvakapetwa kaviri kune mamwe mafiriji ekugadzira, zvinoreva kutonhora kwepamusoro / kupisa kwekuita neiyo yakafanana firiji inoyerera.

 Kuvandudzwa mukushanda kwesimba

Zvidzidzo zvenyaya zvinoratidza kuti kutama kubva kuHFC R404A kuenda kufiriji yechisikigo R290, paavhareji, inogona kubvumira kusvika kugumi muzana kuvandudzika mukuchengetedza simba.

Zvirinani thermal regime mukufarira compressor

Mukufambirana nemafiriji echisikigo, kune mitsva yekugadzira misanganiswa inowanikwa mumusika ine yakaderera GWP, inozivikanwawo seA2Ls. Tafura (pamufananidzo) inoratidza maitiro makuru anofanirwa kutariswa kana wasvika pasarudzo. Imwe yeiyi maitiro ihurumende yekupisa, iri nani mumafiriji echisikigo, zvichireva kuti haidzise compressor zvakanyanya seA2Ls. Ichi chikamu chinobatsira pakusimba kwesimba uye kuvimbika kwecompressor.
