Ayini ama-hydrocarbon (HCs)

Ama-Hydrocarbon (HCs) yizinto ezakhiwe ngama-athomu e-hydrogen ahlanganiswe nama-athomu ekhabhoni. Izibonelo i-methane (CH4), i-propane (C3H8), i-propene (C3H6, eyaziwa nangokuthi i-propylene) ne-butane (C4H10).

Konke lokhu kuyavutha futhi akunabuthi ngokwesigaba sokuphepha se-ASHRAE 34: isigaba sazo sokuphepha singu-A3, no-“A” okusho ukuthi “ubuthi obuphansi” kanye no-“3” okusho “ukuvutha okukhulu”.

 

 

Izinzuzo zama-HC njengeziqandisi

Kunezinzuzo ezintathu eziyinhloko:

Amandla aphansi okufudumala komhlaba

Ama-HC anamandla aphansi kakhulu okufudumala kwembulunga yonke, Ngakho asiza ekwehliseni i-CO₂ukukhishwa kwekhabhoni uma sisebenzisa ama-hydrocarbon njengesiqandisi.

Ivela kalula emvelweni

Ama-HC akhishwa enhlabathini, futhi kanye namafutha. Imithombo yabo eMhlabeni mikhulu. Futhi kulula ukuwathepha, futhi, intengo yawo iphansi kuneyamanye amafriji okwenziwa.

Ukusebenza okungcono kwesiqandisi

 Ama-HC asebenza ngempumelelo kakhulu ukupholisa/ukushisisa njengesiqandisi kunamanye. Eqinisweni, ukushisa kwazo okucashile kokuhwamuka kuphakeme ngokuphindwe kabili kunezinye iziqandisi zokwenziwa, okusho umphumela wokupholisa/wokushisa okuphezulu nokugeleza kwenqwaba yesiqandisi efanayo.

 Ukuthuthukiswa kokusebenza kahle kwamandla

Ucwaningo lwezehlakalo lubonisa ukuthi ukufuduka kusuka ku-HFC R404A kuya kusiqandisi semvelo esingu-R290, ngokwesilinganiso, kungavumela ukuthuthukiswa okungamaphesenti ayishumi ekongeni amandla.

Umbuso oshisayo ongcono ovuna i-compressor

Ngokuhambisana neziqandisi zemvelo, kunezingxube ezintsha zokwenziwa ezitholakala emakethe ezine-GWP ephansi, eyaziwa nangokuthi ama-A2L. Ithebula (elisesithombeni) likhombisa imibandela esemqoka okufanele ibhekwe uma kufinyelelwa esinqumweni. Enye yalezi zindlela wumbuso oshisayo, ongcono eziqandisini zemvelo, okusho ukuthi ayishisisi i-compressor njengama-A2L. Lesi sici sinomthelela ekusebenzeni kahle kwamandla kanye nokuthembeka kwe-compressor.
