Ukonga Amandla Okungu-30%: Ukuthuthukiswa Kwefriji Yezohwebo
Kwadalwa ngo 08.18
Emkhakheni wezokudla kanye nezitolo, amafriji ezohwebo abangela ngaphezu kuka-40% wokushaja kagesi wonke esitolo. Ngokuqaliswa kwezindinganiso ezintsha zokusebenza kahle kwamandla ze-EU ngo-2023 kanye nokukhuphuka kwezindleko zikagesi, ukuthuthukisa ukusebenza kahle kwefriji sekubalulekile ekwehliseni izindleko. Lesi sihloko sihlaziya amasu amathathu ayinhloko asuselwa ezimweni zobunjiniyela zangempela.
1. Izimiso Zohlelo Lokufriza Nokusebenza Kahle
Umongo wokusebenza kahle kwamandla unqunywa yi-COP (Coefficient of Performance):
- COP = Qc / W(Qc: amandla okupholisa, W: amandla okufaka)
Ngokwe-GB 26920.2-2022, i-COP eyisisekelo yamafriza amile angu-500L ingu-1.8. Izingxenye ezibalulekile ezithinta i-COP:
Ingxenye | Isisindo Somthelela | Amandla Okuthuthukisa |
I-compressor | 45% | Ubuchwepheshe be-inverter bunciphisa ukusetshenziswa ngamaphesenti angu-25-30 |
I-Condenser | 25% | Umklamo we-Microchannel uthuthukisa ukukhishwa kokushisa ngamaphesenti angu-40 |
Izivalo Zeminyango | 15% | Izivalo zikazibuthe zinciphisa ukuvuza komoya obandayo ngamaphesenti angu-70 |

2. Izixazululo Zokusebenza Kahle Kwamandla
2.1 Ukuthuthukiswa Kohlelo Lokushintshana Ukushisa
- Ukuthuthukiswa kwe-condenser
- Ukushintsha kwe-refrigerant
(Umthombo: IIR Refrigerant Database)
"Izinhlelo ze-R290 zikhombisa ukonga amandla okungu-12% ku-18°C uma kuqhathaniswa nezinto zokupholisa ezijwayelekile, nezinga lokukhishwa kwe-compressor eliphansi ngo-15°C"

2.2 Izindlela Zokulawula Eziqondile
Imodi Yokulawula | Ukusetshenziswa Kwansuku Zonke(kWh) | Ukushintsha Kwezimfanelo(±°C) |
Isivinini Esimisiwe | 26.5 | 2.1 |
I-PID Inverter | 18.3 | 0.5 |
Izimo zokuhlola: 500L freezer, imvelo engu-25°C. Umthombo: UL Certification Lab Report ECS-2307
3. Izinkomba Zokuxwayisa Zokunakekelwa
Ukugcinwa kokuvikela kuvimba ukwehla kokusebenza. Izinkomba ezibalulekile:
- Ubukhulu be-frost ye-evaporator
(Idatha yokusebenza kweNkampani iyadingeka)
- Ukuqina kokuvula
- Umjikelezo we-compressor
4. Isifundo Som case Sezithameli
Iphrojekthi Yokuvuselela I-Chain Supermarket (2023)
- Inselelo
- Izixazululo
- Kufakwe ama-compressor e-EC inverter
- Kungezwe izivalo zikazibuthe zamakhethini
- Kusetshenziswe ukuqapha kwezinga lokushisa nge-IoT
- Imiphumela
- Ukusetshenziswa kwansuku zonke kweyunithi kwehliswe kusuka ku-24.7kWh kuya ku-17.3kWh
- Ukonga ngonyaka: $8,600 (ngo-$0.14/kWh)
- Isikhathi se-ROI
