Chii chinonzi mahydrocarbon (HCs)?

Mahydrocarbon (HCs) zvinhu zvinoumbwa nemaatomu ehydrogen akabatana nemaatomu ekabhoni. Mienzaniso yacho i methane (CH4), propane (C3H8), propene (C3H6, inozivikanwawo se propylene) uye butane (C4H10).

Zvese izvi zvinobvira uye hazvina chepfu zvichienderana nechirongwa chekuchengetedza cheASHRAE 34: kirasi yavo yekuchengetedza iA3, ine "A" ichireva "chepfu shoma" uye "3" ichireva "kubvira kwakanyanya".

 

 

Mabhenefiti eHCs semafiriji

Pane zvakanakira zvikuru zvitatu:

Kudzikira kwekudziya kwepasi rose

MaHC ane mukana mudiki wekudziya kwepasi rose, saka zvinobatsira mukuderedza CO2₂kuburitswa kwemhepo kana tikashandisa mahydrocarbon semuchina wekuchengetedza chando.

Yakabva kune zvakasikwa zviri nyore

MaHC anotorwa kubva muvhu, pamwe chete nemafuta. Zvaanowana pasi pano zvakawanda. Uye zviri nyore kuzvibata, zvakare, mutengo wazvo wakaderera pane wemamwe mafiriji ekugadzira.

Zviri nani kushanda kwefiriji

 MaHC anoshanda zvakanyanya pakutonhodza/kudziisa semuchina wekuisa mufiriji kupfuura mamwe. Kutaura zvazviri, kupisa kwavo kwemhepo kwakatopetwa kaviri pane mamwe mafiriji ekugadzira, zvinoreva kuti kutonhora/kudziyisa kwakanyanya nekuyerera kwakafanana kwemuchina wekuisa mufiriji.

 Kuvandudzwa kwekushanda zvakanaka kwesimba

Ongororo dzezviitiko dzinoratidza kuti kutama kubva kuHFC R404A kuenda kuchinhu chinotonhorera chenatural R290, paavhareji, kunogona kubvumira kuvandudzwa kwekuchengetedza simba ne10 muzana.

Mutemo wekupisa uri nani uchitsigira compressor

Pamwe chete nemafuta emuchina wekugadzirisa mafiriji, kune masanganiswa matsva ekugadzira anowanikwa pamusika ane GWP shoma, inozivikanwawo seA2Ls. Tafura (iri pamufananidzo) inoratidza zvinodiwa zvikuru zvinofanira kufungwa nezvazvo pakusarudza. Chimwe chezvinhu izvi imhando yekupisa, iyo iri nani mumafuta emuchina wekugadzirisa mafiriji, zvichireva kuti haipisi compressor zvakanyanya seA2Ls. Izvi zvinobatsira pakushanda nesimba uye kuvimbika kwecompressor.
