Don Allah a lura! Waɗannan firiji huɗu masu ƙonewa da fashewa!

1. R32 firiji

R32, wanda kuma aka sani da difluoromethane da carbon difluoride, ba shi da launi da ƙamshi, kuma yana da matakin tsaro na A2. R32 shine madadin Freon tare da kyawawan kaddarorin thermodynamic. Yana da halaye na ƙananan tafasasshen ruwa, ƙarancin matsin lamba da matsin lamba, babban coefficient firiji, ƙimar hasara na ozone, ƙaramin tasirin greenhouse, mai ƙonewa da fashewa. Iyakar konewa a cikin iska shine 15%~ 31%, kuma zai ƙone kuma ya fashe idan akwai buɗewar wuta.

R32 yana da ƙarancin ɗanɗano mai ɗimbin yawa kuma yana da ƙima mai ƙarfi. Kodayake R32 yana da fa’idodi da yawa, R32 mai sanyaya wuta ne kuma mai fashewa. Shigarwa da kiyaye kwandishan yana da haɗari. Yanzu haɗe tare da abubuwan rashin tabbas na R32, dole ne a yi la’akari da batutuwan aminci. Dole ne a cire shigarwa da walda kayan aikin sanyaya R32.

2. R290 firiji

R290 (propane) wani sabon nau’in firiji ne mai muhalli, galibi ana amfani dashi a cikin kwandishan na tsakiya, masu sanyaya iska mai dumama zafi, kwandishan na gida da sauran ƙananan kayan aikin firiji. A matsayin mai sanyaya ruwa, R290 yana da ƙimar ODP na 0 da ƙimar GWP ƙasa da 20. Idan aka kwatanta da masu sanyaya ruwan sanyi, R290 yana da fa’idodin muhalli a bayyane, kamar yadda aka nuna a ƙasa:

2.1 Rushewar ozone Layer ta R22 firiji shine 0.055, kuma coefficient na dumamar yanayi shine 1700;

2.2 Rushewar ozone Layer ta R404a firiji shine 0, kuma daidaiton dumamar yanayi shine 4540;

2.3 Rushewar ozone Layer ta R410A firiji shine 0, kuma daidaiton dumamar yanayi shine 2340;

2.4 Rushewar ozone Layer ta R134a firiji shine 0, kuma daidaiton dumamar yanayi shine 1600;

2.5 Rushewar ozone Layer ta R290 firiji shine 0, kuma ma’aunin dumamar yanayi shine 3,

Bugu da kari, mai sanyaya R290 yana da halayen mafi girman latent zafi na ƙaura, ingantaccen ruwa, da tanadin makamashi. Koyaya, saboda halayensa masu ƙonewa da fashewa, adadin jiko yana da iyaka, kuma matakin aminci shine A3. Ana buƙatar isasshen iska yayin amfani da matakin sanyaya R290 kuma an hana buɗaɗɗen wuta, saboda haɗuwar iska (iskar oxygen) na iya haifar da abubuwan fashewa, kuma akwai haɗarin ƙonewa da fashewa yayin haɗuwa da tushen zafi da buɗe wuta.

3. R600a firiji

R600a isobutane sabon salo ne na injin daskararre na hydrocarbon tare da kyakkyawan aiki, wanda aka samo shi daga kayan abinci na halitta, baya lalata layin ozone, ba shi da tasirin greenhouse, kuma yana da muhalli. Halayensa sune manyan latent zafi na ƙaura da ƙarfin sanyaya mai ƙarfi; kyau kwarara yi, low isar matsa lamba, low ikon amfani, da kuma jinkirin tashi na load zazzabi. Jituwa tare da daban -daban kwampreso lubricants. Iskar gas ce mara launi a yanayin zafin jiki da ruwa mara launi kuma mai haske a ƙarƙashin matsin lamba. R600a galibi ana amfani dashi don maye gurbin firiji R12, kuma yanzu galibi ana amfani dashi a cikin kayan aikin firiji na gida.

Ƙarfin ƙimar fashewar R600a mai sanyi shine 1.9% zuwa 8.4%, kuma matakin aminci shine A3. Zai iya samar da cakuda mai fashewa idan aka gauraya da iska. Yana iya ƙonawa da fashewa lokacin da aka fallasa shi ga tushen zafi da buɗaɗɗen harshen wuta. Yana amsawa da ƙarfi tare da oxidants. Tururinsa ya fi iska nauyi. Ƙananan ɓangaren ya bazu zuwa nesa mai yawa, kuma zai ƙone lokacin da aka haɗu da tushen wuta.

4. R717 (ammoniya) firiji

4.1 A ƙarshe, bari muyi magana game da R717 (ammonia) firiji. Ammoniya ya fi hatsari fiye da nau’in firiji guda uku da ke sama. Yana cikin matsakaici mai guba kuma yana da matakin guba.

4.2 Lokacin da yawan kumburin tururin ammoniya a cikin iska ya kai kashi 0.5 zuwa 0.6%, ana iya yiwa mutane guba ta wurin zama a cikinsa na rabin awa. Yanayin ammoniya ya ƙaddara cewa dole ne a kayyade aiki da kiyaye tsarin ammoniya, kuma ma’aikatan firiji su kula da shi lokacin amfani da shi.
