Ukunwetshwa Kwesikhathi Sokuphila: Umhlahlandlela Wokunakekela Ophakeme WamaFrigi
Kwadalwa ngo 08.18
Imodeli Ye-ROI Yokugcinwa: Ukonga Kwe-TCO Okungu-¥3.2 Ngayo Yonke I-¥1 Etshaliwe
Ukuhlaziywa kwe-ASHRAE 2023 LCC kubonisa ukuthi ukunakekelwa okuchwepheshile kwandisa isikhathi sokusebenza kwefriji yezohwebo kusuka eminyakeni engu-8 kuya kwengu-12 (+50%), kunciphisa izindleko zobunikazi eziphelele ngama-67%. Amayunithi angandelelwa abonisa:
• Ukulahlekelwa kokusebenza okungaphezu kuka-35% ngonyaka wesi-5 (ukugqoka kwe-compressor >0.1mm)
• Ukwenyuka kwezinga lokwehluleka okusheshayo (imvamisa yokwehluleka ngonyaka wesi-6 iphindwe ka-8 ngonyaka wokuqala)
Uhlobo Lwezindleko | Akukho Ukunakekelwa | Ukunakekelwa Okuchwepheshile | Ukuncishiswa |
Izindleko Zamandla | ¥38,600 | ¥24,800 | -35.8% |
Ukushintshwa Kwezingxenye | ¥16,200 | ¥5,300 | -67.3% |
Ukulahlekelwa Isikhathi Sokuma Komsebenzi | ¥9,400 | ¥1,100 | -88.3% |
Qaphela: Ngokusekelwe ku-¥1.2/kWh, ukusebenza kwansuku zonke amahora angu-18 (Umthombo: AREPO 2024)
Izinqubo Zokunakekelwa Kwezingxenye Eziyinhloko
1. Ukunakekelwa Okujulile Kwe-Compressor (njalo ngamahora angu-2000)
- Ukushintsha Uwoyela:
- Ukuhlolwa Kwe-Winding:
![[Compressor Diagram]]/images/compressor-maintenance.jpg
Umfanekiso: Amaphuzu abalulekile okunakekela (Okubomvu: Ingilazi yokubona uwoyela/Okuluhlaza okwesibhakabhaka: Amaterminali)
2. Ukunakekela Okuhlakaniphile Kwe-Condenser
Izinga Lothuli (μg/m³) | Isikhathi | Indlela | Ukubuyiselwa Kwe-Fin Clearance |
≤50 (Kuhlanzekile) | Izinsuku ezingama-90 | Ukuphefumula komoya (0.3MPa) | ≥98% |
50-150 (Ekhishini) | Izinsuku ezingama-45 | Ukuhlanza okungathathi hlangothi + ibhulashi elithambile | ≥95% |
Uhlelo Lokubikezela Ukunakekela
Imodeli ye-FTA (Fault Tree Analysis):
![[FTA Diagram]]/images/fta-diagram.png
Umfanekiso: I-FTA yohlelo lokupholisa (Umcimbi ophezulu: Ukwehluleka ukupholisa)
Imingcele Ebucayi Yezinkomba:
- I-Evaporator ΔT >8℃ (Okujwayelekile:4-6℃) → Inkinga yokubanda
- Ukushintashintsha kwamandla kwe-compressor >±15% → Ingozi yokuvuza kwe-refrigerant
- Umehluko wokushisa komphetho womnyango >2℃ → Isixwayiso sokwehluleka kokuvala
Ikhithi Yobungcweti Yokulungisa
Ukuhlola Kagesi:
- I-Fluke 1587 Insulation Tester (ukunemba ±1.5%)
- I-True RMS Clamp Meter (ukulungisa kwe-0.1A)
Amathuluzi Emishini:
- I-Vacuum Pump (i-vacuum ephezulu ≤5Pa)
- Isikali Sezinga Elikabili R134a/R404a (ukunemba ±1g)
Isifundo: Ukunwetshwa Kwempilo Yokusebenza Ngamaphesenti angu-50
Imiphumela yesikhungo sokulawula ukuthuthwa kwempahla ebandayo ngemva kokuqaliswa:
Iqembu | Iminyaka Yokusebenza | Izinga Lokushintshwa Kwe-Compressor | Ukwehla Kokusebenza Konyaka |
Ukunakekelwa Okujwayelekile | 6 | 42% | 5.8%/ngonyaka |
Ukunakekelwa Okuchwepheshile | 6 | 6% | 1.2%/ngonyaka |
Ubuchwepheshe: I-spectroscopy kawoyela (njalo ngamahora angu-800) ithole ukuwohloka okungu-97% kusenesikhathi
