Ukuhlolisisa komkhiqizo
Ibizo lekhemikhali: Difluoromethane
Inomboro ye-CAS: 75-10-5
Ifomula yamamolekhyuli: CH2F2
Ubunzima bamamolekhyuli: 52.02 g/mol�
Ibizo elijayelekileko: R-32 (njengefriji)
I-difluoromethane (R-32) yi-hydrofluorocarbon (HFC) enganambala, enganabuthi, begodu evutha kancani enekghono elihle khulu lokutjhisa. Njengefriji yesizukulwana esilandelako esingalimazi ibhoduluko, sele ibe yindlela eqakathekileko yokusebenzisa amafriji wesintu ane-GWP ephezulu (Global Warming Potential), eyaziwa khulu ngokulingana kwayo, ukuphepha, nokuvikela ibhoduluko.
Izakhiwo eziqakathekileko
| Ipahla | Ukucaciswa | Ubuhle |
| Indawo yokubilisa (ku-1 atm) | -51.6°C (-60.9°F) | Ikghonakalisa ukudlulisa ukutjhisa okusebenzako eensetjenzisweni ezisezingeni eliphasi |
| I-GWP (Ukufuthumala kwePhasi, iminyaka eyi-100) | 675 | Ngaphasi khulu kune-R - 410A (GWP = 2088) kanye ne-R - 22 (GWP = 1810), ukwehlisa umthelela wekhabhoni |
| I-ODP (I-Ozone Depletion Potential) | 0 | Akukho ukulimala kwe-ozone layer, ngokukhambisana nemithetho yezebhoduluko yamazwe ngamazwe (isib., i-Montreal Protocol) |
| Izinga lokutjhisa eliqakathekileko | 78.1°C (172.6°F) | Ilungele ukupholisa umoya kanye neenhlelo zepompo yokutjhisa ezisebenza eendaweni ezinezinga lokutjhisa eliphakathi nendawo ukuya eliphezulu |
| Ukuvutha | Ivutha kancani (ukuhlukaniswa kwe-A2L nge-ASHRAE 34) | Iphephile eendaweni ezinengi zokuhlala nezokurhweba ngomklamo ofaneleko |
| Ukudlulisa ukutjhisa | Phakathi (ngcono kune-R - 410A) | Ikhuphula ukusebenza kuhle kokupholisa/ukufuthumeza, ukwehlisa ukusetjenziswa kwamandla wemitjhini |
Iinsetjenziswa ezijayelekileko
I-R-32 isetjenziswa khulu emikhakheni ehlukahlukeneko yamabubulo neyabathengi ngebanga lokusebenza kwayo okuhle khulu kanye neenzuzo zebhoduluko:
Ukupholisa umoya eendaweni zokuhlala nezokurhweba: Njengokupholisa okuphambili kwamayunithi we-AC ahlukanisiweko, ama-AC wamafasidera, kanye neenhlelo ze-VRV (Variable Refrigerant Volume). Ithatha indawo ye-R-410A ngemitjhini emitjha, yehlisa ukusetjenziswa kwamandla nge-10-15%.
Amapompo womtjhiso: Alungele amapompo womtjhiso womthombo womoya (ama-ASHP) kanye namapompo womtjhiso womthombo wamanzi (ama-WSHP), anikela ukusebenza okuzinzileko kokufuthumala ngitjho nasemazingeni womtjhiso aphasi (-10°C ukuya ku-5°C).
Iinhlelo zokupholisa: Isetjenziswa emafrijini amancani ukuya kwamaphakathi, amakheyisi wokubonisa, kanye namayunithi wokugcina amakhaza, ukuqinisekisa ukupholisa okusebenzako ngaphandle komthelela omncani emvelweni.
Iinsetjenziswa zokuvuthela i-Foam: Kwezinye iinkambo zebubulo, i-R-32 isebenza njenge-ejenti yokuphefumula yama-foam we-polyurethane aqinileko, okwenza ngcono izakhiwo zokuvikela i-foam.
Ukubunjwa kwe-Organic: Kusebenza njengento engakalungiswa ekukhiqizeni amakhemikhali ane-fluorine, kufaka hlangana imithi kanye nama-polymer akhethekileko.
Ukuphepha nokuthobela
Imihlahlandlela yokuPhepha
Ukuphathwa: Balekela ukuthintana ngqo nesikhumba/amehlo; sebenzisa amagilavu wokuzivikela, amagogolosi, kanye nemitjhini yokuphefumula eendaweni ezingangeni umoya omuhle.
Ukugcina: Beka endaweni epholileko, eyomileko, enomoya omuhle kude namalangabi avulekileko, amazinga womtjhiso aphezulu, kanye nama-ejenti we-oksijini. Sebenzisa iintjalo ezivaliweko, ezingagqwali (isib., amasilinda wensimbi nofana we-aluminiyamu).
Ukuthutha: Landela imithetho ye-UN yokuthutha amafriji (inomboro ye-UN: 3252); qiniseka bona amasilinda avikelwe kuhle begodu afakwe amalebula.
Ukuthobela imithetho
Ihlangabezana namazinga we-ASHRAE 34 (ukuhlukaniswa kokuphepha kwe-A2L).
Ukuthobela umThetho we-EU F-Gas (UmThetho (EU) 2014/512), ukukhawulela ukukhishwa kwe-F-gas nokukhuthaza ezinye iindlela ezine-GWP ephasi.
Ivunywe ngabakhiqizi bemitjhini emikhulu (isib., i-Daikin, i-Mitsubishi Electric, i-Gree) ukobana isetjenziswe kumamodeli wabo wakamuva we-AC kanye namapompo womtjhiso.
Iphepha ledatha yezobuchwepheshe (TDS) amaphuzu aqakathekileko
| Ipharamitha | Ukusiza | Indlela yokuhlola |
| Ukuhlanzeka (umzuzu) | 99.9% | GC (Gas Chromatography) |
| Ukuqukethwe komswakama (ubukhulu) | 10 ppm | U-Karl Fischer Titration |
| Okuqukethwe yi-esidi (ubukhulu) | 0.1 ppm | Ukulinganisa |
| Insalela engatjhugulukiko (ubukhulu) | 10 mg/kg | Igravimethri |
| Umfutho womhwamuko (ku-25°C) | 1.72 MPa | Isilinganisi sokugandeleleka |
Kubayini Sikhetha I-Difluoromethane Yethu (R-32)?
Ukuhlanzeka okuphezulu: Ukuhlanzeka okungaguqukiko okungu-99.9% kuqinisekisa ukusebenza okuzinzileko kwemitjhini nokuphila isikhathi eside.
Ilungele ibhoduluko: I-GWP ephasi (675) isekela iminqopho yokungathathi ihlangothi kwekhabhoni begodu ihlangabezana nemithetho eqinileko yezebhoduluko.
Ukubiza: Ukusebenzisa kuhle ukutjhisa okuphezulu kwehlisa iindleko zamandla kubasebenzisi bokugcina, ngesikhathi amakghono wethu wokuphakela ngobunengi ehlisa iindleko zokuthenga.
Isekelo lePhasi loke: Sinikela ngokubonisana kwezobuchwepheshe, ukubandulwa kokuphepha, nokulethwa ngesikhathi kumakhasimende ephasini loke, ngezitifiketi ezifaka hlangana i-ISO 9001 ne-REACH.
