ukitaka kusave umeme wa friji jizoeshe kuwasha friji Asubuhi ifanye kazi halafu jioni zima km kuna vitu vya kuharibika basi iwashe kuanzia saa 6 usiku
ila kusave umeme jenga utaratibu wa kuwasha Asubuhi izime jioni saa 12 au 11 utasave sana Unit zako za umeme mana balaa la saa 1 usiku umeme huu wa bongo na vitu vya winding utaumiza Unit zako

1 to 5 inamaana 'warm' to 'coldest' settingHizi namba za kwenye switches za fridges zinamaanisha nini exactly...
Mfano 1 mpaka 5...ina impacts gani kwenye utendaji kazi wa fridge na ulaji wa umeme?
NIMESHIBA MAELEZO YAKO... BASI NILIDHANI INA UHUSIANO NA ULAJI WA UMEME.1 to 5 inamaana 'warm' to 'coldest' setting
Friji nyingi zina range ya 0.5°C - 4°C ambapo 4°C ni joto ukilinganisha na 0.5°C (ubaridi)
so hiyo dial 1 mpaka 5 actually ni 4°C na 0.5°C respectively
i.e
Dial 1 correspond to 4°C (joto)
Dial 5 correspond to 0.5°C (ubaridi)
Dial 2, 3, 4 ni simple math, ni any temperature range between 4°C mpaka 0.5°C.
Kuhusu kula umeme:
Actually fridge temperature dial control haili umeme.
Compressor ikizima hapo haili umeme
Ukiset dial (1-5) haili ememe wowote
Umeme unaliwa na compressor regardless na dial setting.
Dial ni kama air valve control just una control kiasi cha air refregerant iliyokwisha zalishwa na compressor ipite kwenye freezer
Ni Sawa na kutumia pump inayokula umeme unit 2 kujaza tank. Halafu uzime pump then Una control speed ya maji Kwa koki kwenye tank. Maji ujazo yanajulikana, unit 2 zimeshaliwa na pump, ku control speed ya koki kwenye tank hakuli umeme wowote.
Pump= compressor
Koki= temperature dial control
Na je vipi kuhusu kiwango cha watts na ulaji wa umeme?1 to 5 inamaana 'warm' to 'coldest' setting

Naomba ufafanuzi tafadhali...

BABA SALUTE KWAKO KWA ELIMU...Simple Thermodynamic cycle Tu:
Ulaji wa umeme wa friji inategemea na factors kadhaa
1. Constant factor
2. Variable factors/miscellaneous usage
1. Constant factor
Hii ni Electrical power rating ya friji kuonesha friji/compressor inataka Power kiasi gani ili iwe ON bila kuweka chochote ndani.
Mfano 130Watts, etc
Watts = ukubwa wa friji
Kwahiyo ukiwasha friji yako bila kuweka kitu ndani inakula 130W Kwanza,
Ikiwaka say Kwa masaa 10 bila kitu ndani inakula 130watts x10hrs= 1.3kWh units. Hapa usihesabu compressor cycles
2. Variable factors/compression cycles
Hapa ni power ya kua ON + factors mbali mbali zinazofanya umeme ulike Sana
Mfano
-kufungua mlango wa friji
-friji ikiwa na Ka uwazi cold air ina leak
-poor evaporation/fault
-compressor fault
-etc
Mfano
Ukifungua mlango wa friji ikiwa inarun
Cold air inapotea na hot air inaingia ndani ya friji hii hufanya compressor ichukue kiwango kikubwa zaidi cha umeme kukeep temperature ileile iliyopotea. Ndiyo mana friji za LG baadhi zina kioo yani unaangalia cha kuchukua kabla hujafungua mlango for energy savings, inaloose compression
Sasa hii loss + power ON loss = cost
Mfano2:
Ukiweka chakula cha 40°C compressor itakula umeme zaidi kuzalisha low temperature refrigerant ku cool hii 40°C mpaka dial set point, ambayo ni tofaut na aliyeweka chakula cha 20°C itakula umeme chini ya aliyeweka 40°C for the same dial setting. Thermodynamic cycle tu hapo
The colder the system, the higher the supply energy needed to keep that lowest temperature and make system colder, and vice versa.
Yes ina msaada SanaBABA SALUTE KWAKO KWA ELIMU...
JE MFANO NATUMIA FRIJI YA MR UK... WATT 300 NDOGO MLANGO MMOJA...NIFANYE NINI ILI NISAVE UMEME KULIKA. .. JAPO INAJIZIMA NA KUJIWASHA? JE HIYO KUJIZIMA NA KUJIWASHA INA MSAADA WOWOTE KWENYE UMEME KULIKA?
