| Ukuqhuba kweThermal | Phezulu (kungcono kune-R - 410A) | Iphucula ukusebenza kakuhle kokupholisa/ukufudumeza, inciphisa ukusetyenziswa kwamandla kwezixhobo |
Izicelo eziqhelekileyo
I-R-32 isetyenziswa kakhulu kumacandelo ahlukeneyo emizi-mveliso nabathengi ngenxa yokusebenza kwayo okuphezulu kunye neenzuzo zokusingqongileyo:
Umoya opholileyo kwiindawo zokuhlala nezorhwebo: Njengefriji ephambili yeeyunithi ze-AC ezihluliweyo, ii-AC zefestile, kunye neenkqubo ze-VRV (Variable Refrigerant Volume). Ithatha indawo ye-R-410A kwizixhobo ezintsha, inciphisa ukusetyenziswa kwamandla nge-10-15%.
Iimpompo zobushushu: Zilungele iimpompo zobushushu ezivela emoyeni (i-ASHP) kunye neempompo zobushushu ezivela emanzini (ii-WSHP), ezibonelela ngokusebenza okuzinzileyo kokufudumeza nokuba kumaqondo obushushu aphantsi (-10°C ukuya kwi-5°C).
Iinkqubo zokuFrijisa: Zisetyenziswa kwiifriji ezincinci ukuya kweziphakathi, kwiindawo zokubonisa, nakwiindawo zokugcina izinto ezibandayo, ukuqinisekisa ukupholisa okusebenzayo kunye nefuthe elincinci kwindalo esingqongileyo.
Iiarhente Zokuvuthela Igwebu: Kwezinye iinkqubo zoshishino, i-R-32 isebenza njengearhente yokuvuthela igwebu le-polyurethane eliqinileyo, iphucula iipropati zokugquma igwebu.
Ukwenziwa kwezinto eziphilayo: Kusebenza njengezinto ezisetyenziswa ekuveliseni iikhemikhali ezifakwe i-fluorinated, kuquka amayeza kunye nee-polymers ezikhethekileyo.
Ukhuseleko kunye nokuThotyelwa kweMithetho
Izikhokelo zoKhuseleko
Ukuphatha: Kuphephe ukudibana ngqo nolusu/namehlo; sebenzisa iiglavu zokuzikhusela, iiglasi zokukhusela, kunye nezixhobo zokuphefumla kwiindawo ezingenamoya ungako.
Indawo yokugcina: Gcina kwindawo epholileyo, eyomileyo, enomoya ococekileyo kude namalangatye avulekileyo, amaqondo obushushu aphezulu, kunye nezinto ezikhupha ioksijini. Sebenzisa izikhongozeli ezivaliweyo nezimelana nokugqwala (umz., iisilinda zentsimbi okanye zealuminiyam).
Ezothutho: Thobela imithetho ye-UN yokuthutha iifriji (inombolo ye-UN: 3252); qinisekisa ukuba iisilinda zikhuselekile kwaye zineelebhile ezifanelekileyo.
Ukuthobela imithetho
Ihlangabezana nemigangatho ye-ASHRAE 34 (uhlelo lokhuseleko lwe-A2L).
Ihambelana noMgaqo we-EU F-Gas (uMgaqo (i-EU) ka-2014/512), ithintela ukukhutshwa kwegesi ye-F kunye nokukhuthaza ezinye iindlela zokusebenzisa i-GWP ephantsi.
Ivunyiwe ngabavelisi bezixhobo eziphambili (umz., iDaikin, iMitsubishi Electric, iGree) ukuze isetyenziswe kwiimodeli zabo zamva nje ze-AC kunye neepompo zobushushu.
