Ukulahlwa kwesiqandisisi kuyindlela ebalulekile

Umkhuba wokubuthelwa kwabantu abaningi kanye nokucubungula imishini yamandla kagesi esekude uye wajwayelene namazwe anezinga eliphakeme lokuphila, ngoba kukhona lapho kunakekelwa kakhulu kokubili isimo semvelo kanye nokusetshenziswa kahle kwezindawo. Ngempela, isikhala, esivela emazweni amaningi omhlaba ukuthengiswa kwemfucuza yasemakhaya, singahle sihlelwe phansi, futhi singagcini lapho udoti owonakele.

Indawo ebalulekile ekusetshenzisweni kabusha yikusetshenziswa kweziqandisini ezindala, ngoba amasistimu abo agcwele i-refrigerant. Kuyinto into ephumelelayo edlulisa ukushisa kusuka ohlelweni oluya kwesinye. Noma kunjalo, ukungena emkhathini kubangela ukulimala okukhulu kokubili imvelo nomuntu. Njengamanje, kunezinhlobo ezintathu eziyinhloko zeziqandisisi: i-chlorofluorocarbons (CFCs), i-hydrochlorofluorocarbons (HCFCs), nama-hydrofluorocarbons (HFCs).

I-molecule ye-chlorine esakhiweni sokuqala yenza kube yingozi kakhulu emvelweni. Lokhu kungenxa yokuthi i-refrigerant yalolu hlobo inzinzile ngokwanele futhi iyancipha kabi lapho ingena emkhathini. Ngakho-ke, ukuqoqwa kwalesi sakhi kwenzeka, okuholela ekubhujisweni kocingo lwe - ozone, ukwanda komphumela wokushisa nokunye okungajabulisi nokulimaza kakhulu empilweni.

Iqembu lesibili liqukethe ama-athomu e-hydrogen, okwenza kube khona ukubhujiswa okusheshayo kwama-freon ezilimazayo, futhi kuvimbela ukuqongelela kwabo emvelweni.

Iqembu lesithathu aliqukethe i-chlorine nhlobo. Lokhu kusho ukuthi izinto ezinjalo ziphephile futhi zingu-substitute for CFCs kanye ne-HCFCs.

Ukulahlwa kwesiqandisisi kusho ukuhlukaniswa kwazo zibe izingxenye ezithunyelwa ekusetshenzisweni noma ekubhujisweni ngendlela ephumelela kakhulu. Isinyathelo esibaluleke kakhulu ekuvuseleleni kabusha i-refrigerant echazwe ekuqaleni. Phela, kuyingozi enkulu emvelweni.

Ukusetshenziswa kwesiqandisini kungenziwa ngezindlela eziningana. Ake sicabangele ngamunye wabo.

1. Ukuzikhandla. Akusilo ukubhujiswa okuphelele kweyunithi elidala. Lolu hlobo lungabhekwa njengesiteji sokulungiselela, okuyinto eyenza lula umsebenzi wokucubungula amaphuzu.

2. Ukukhokhelwa okukhokhelwayo nokusetshenziswa kwesiqandisini. Uma kwenzeka ungafuni ukwenza umsebenzi ongcolile, ungamema ummeli wenkampani, leyo imali ethile ezosindisa indlu yakho kusukela kudala.

3. Ukulahlwa kwamahhala kwamafriji. Uma ufisa, ungathola inkampani eyokwenza yonke inqubo mahhala. Lokhu kuvame ukukwenziwa ngabakhiqizi abakhulu bokuziqhenya. Isibonelo, uma uthenga idivayisi entsha, isaphulelo sivame ukuhlinzekwa ngezindleko zomdala. Noma, ezweni lakho, izenzo zingase zenzeke, lapho iqhaza ekuthengweni kweyunithi elisha kuyoba ukulahlwa kwamahhala kwesiqandisisi sakwadala.
