Shin Za a Iya Amfani da Kwampreso na 50Hz a Kan Wutar Lantarki ta 60Hz? Abin da Masu Saye daga Ketare Dole Su Duba

Ga masu saye daga ƙasashen waje, maye gurbin kwampreso ba kasafai yake kasancewa kawai batun daidaita ƙarfin horsepower ko displacement ba. Samar da wutar lantarki na cikin gida yana da muhimmanci sosai. Kwampreso da aka ƙera don wani tsarin lantarki na iya kasa aiki daidai a wani tsarin daban, ko da ƙarfin wutar lantarki ya yi kama da isa a takarda.

Tambayar tana yawan bayyana a ayyukan refrigeration na fitarwa: shin za a iya amfani da kwampreso na 50Hz a kan wutar lantarki ta 60Hz? A wasu lokuta, eh, amma sai dai idan voltage, ƙirar motor, iyakar application, da amincewar manufacturer sun goyi bayan hakan. A wasu lokuta kuma, sakamakon na iya zama ƙaruwar current, raguwar aminci, rashin daidaitaccen aikin sanyaya, ko zafewar motor fiye da kima.

Wannan jagora yana bayyana bambancin aiki tsakanin kwampreso na 50Hz vs 60Hz ga masu rarraba na’urorin refrigeration, kamfanonin service, ’yan kwangilar cold-room, da masu sayen replacement. Haka kuma yana nuna abin da za a bincika kafin sayen compressors don kasuwannin ƙasa da ƙasa.

Dalilin da ya sa Frequency ke da Muhimmanci a Kwampresoshin Refrigeration

Electrical frequency, wanda ake auna shi da hertz (Hz), yana nuna yawan cycles a kowace daƙiƙa da alternating current ke kammalawa. Ƙasashe da yawa suna amfani da wutar 50Hz, yayin da wasu ke amfani da wutar 60Hz. Ana gina kwampresoshin refrigeration ne bisa halayen lantarki na kasuwar da aka nufa, ciki har da frequency, voltage, starting method, protection components, da cooling application.

Ga induction motor compressor, mita tana shafar saurin motar kai tsaye. Motar da aka haɗa da wutar 60Hz gaba ɗaya tana aiki da sauri fiye da irin wannan motar da aka haɗa da 50Hz, muddin ƙirar motar ta yarda ta yi aiki a duka mitocin biyu. Wannan sauyin sauri yana shafar yawan kwararar refrigerant, ƙarfin sanyaya, amfani da wuta, matakin sauti, rawar jiki, da zafin aiki.

Shi ya sa alamar “220V 50Hz compressor” ko “115V 60Hz compressor” ba ƙaramin bayani ba ne. Muhimmin ƙayyadadden daidaituwa ne.

Aikin compressor na 50Hz da 60Hz a sauƙaƙe

Lokacin da mitar compressor ta canza, wasu yanayin aiki da dama na iya canzawa a lokaci guda:

• Saurin mota: Tushen wuta na 60Hz na iya ƙara saurin aikin motar idan aka kwatanta da aiki a 50Hz.
• Ƙarfin sanyaya: Ƙarin sauri na iya ƙara zagayawar refrigerant da ƙarfin aiki, amma ba koyaushe a cikin amintaccen ko amincewarren iyaka ba.
• Shigar wuta: Aiki cikin sauri na iya buƙatar ƙarin wuta kuma ya iya ƙara nauyin lantarki.
• Yanzu da zafi: Rashin dacewar daidaiton voltage zuwa frequency na iya ƙara janyo current da dumamar mota.
• Damuwa ta inji: Ƙarin sauri na iya shafar hayaniya, rawar jiki, dawowar mai, da lalacewa.
• Daidaiton tsarin: Na’urorin faɗaɗa, condensers, evaporators, da cajin refrigerant na iya zama ba su da girman da ya dace da canjin ƙarfin aiki.

Na'urar matsawa wani ɓangare ne na tsarin. Ko da injin ya fara aiki kuma yana gudana, tsarin sanyaya ba lallai ya yi aiki yadda aka nufa ba.

Shin Na'urar Matsawa ta 50Hz Za Ta Iya Aiki a Wutar 60Hz?

Ba a kamata a ɗauka cewa na'urar matsawa ta 50Hz tana da aminci a kan wutar 60Hz ba sai idan farantin bayanai ko takaddun fasaha sun tabbatar da aikin 60Hz. Wasu na'urorin matsawa an ƙera su kuma an amince da su don 50Hz da 60Hz duka, yayin da wasu kuma an tsara su ne don mita ɗaya kawai.

Amsar da tafi aminci ita ce: a yi amfani da na'urar matsawa ta 50Hz a 60Hz ne kawai idan an ƙididdige na'urar don 60Hz a ƙarfin wutar da ake da shi da kuma yanayin amfani.

Alaƙar wuta da mita tana da muhimmanci sosai

Ba za a iya duba mita kaɗai ba. Dole ne a duba wuta tare da ita.

An ƙera motar na'urar matsawa don haɗin wuta da mita na musamman, kamar:

• 440-480V / 60Hz
• 220-240V / 50Hz da 220-230V / 60Hz ƙididdiga biyu

Na'urar matsawa ta 220V 50Hz ba lallai ta dace da wutar 220V 60Hz ba sai idan motar an ƙididdige ta don wannan haɗin. Haka kuma, na'urar matsawa ta 115V 60Hz ba ta dace da tsarin 220V 50Hz kawai saboda ƙarfin na'urar matsawa ya yi kama.

Muhimmin ra’ayi shi ne rabo tsakanin ƙarfin lantarki da mitar aiki. Idan ƙarfin lantarki da mitar aiki ba su dace da juna yadda ya kamata ba, yanayin maganadisu na motar na iya canzawa. Wannan na iya shafar torque, current, da samar da zafi. Mota na iya yin zafi fiye da kima, ta kasa farawa ƙarƙashin kaya, ta tayar da na’urorin kariya, ko ta sami taƙaitaccen rayuwar rufin lantarki.

Ƙarfin sanyaya na iya canzawa a 60Hz

Lokacin da aka yi amfani da compressor da aka tsara don 50Hz a 60Hz ƙarƙashin aminceccen ƙimar dual-frequency, sau da yawa yana aiki da sauri mafi girma. Sauri mafi girma na iya ƙara refrigerant displacement a kowane lokaci. A aikace, compressor na iya bayar da ƙarin ƙarfin sanyaya a 60Hz fiye da a 50Hz, dangane da ƙirar compressor da yanayin aiki.

Wannan ba lallai ya zama fa’ida kai tsaye ba. Compressor mai ƙarfin aiki mafi girma a cikin wannan refrigeration circuit ɗin na iya haifar da matsaloli a ɓangaren tsarin, kamar:

• Short cycling idan load ɗin ya yi ƙasa sosai

Ga kamfanonin service, maye gurbin compressor amma a sake amfani da tsoffin abubuwan farawa na iya zama haɗari sai dai idan sassan sun dace da ƙayyadaddun bayanan sabon compressor.

Yi la’akari da cikakken condensing unit

Lokacin da ake samar da compressors a matsayin wani ɓangare na condensing unit, dole ne motor ɗin fan na condenser, contactor coil, pressure controls, transformer, crankcase heater, da sauran sassan lantarki su dace da wutar lantarki ta gida. Dual-frequency compressor ba ya nufin kai tsaye cewa dukkan unit ɗin ma dual-frequency ne.

Don ayyukan fitarwa zuwa ƙasashen waje, masu saye ya kamata su tabbatar da electrical rating na cikakken assembly, ba kawai samfurin compressor ba.

Lokacin da Ya Kamata a Zaɓi Dual-Frequency Compressor

Dual frequency compressor an ƙera shi kuma an ba shi rating don aiki a kan wutar 50Hz da 60Hz, yawanci cikin iyakokin voltage da aka ƙayyade. Ga masu rarrabawa da ke sayarwa zuwa ƙasashe da yawa, samfuran dual-frequency na iya sauƙaƙa inventory kuma su rage kurakuran zaɓi.
