Canje-canjen refrigerant na iya kuma shafar na'urorin faɗaɗawa, sarrafa matsa lamba, saitunan tsaro, bututun piping, da hanyoyin caji. Compressor cross reference na iya gano wani model mai yiwuwa, amma ba ya maye gurbin cikakken tantancewar sauya refrigerant.

Iyakar aikace-aikace

Iyakar aikace-aikacen compressor dole ne ta rufe aikin da ake nufi. Rukunan gama gari sun haɗa da aikace-aikacen low-temperature, medium-temperature, high-temperature, air-conditioning, da commercial refrigeration. Ba a musayar iyakokin.

Duba amintaccen kewayon yanayin zafin evaporating da condensing, iyakokin discharge temperature, maximum pressure, yanayin return-gas, da duk wani buƙatu na liquid injection ko ƙarin sanyaya. Compressor da ake amfani da shi a cikin ɗakin sanyi na iya samun aiki daban da wanda ake amfani da shi a tsarin comfort air-conditioning, koda kuwa ana bayyana su da adadin capacity masu kama.

Iyakar aikace-aikace tana da muhimmanci musamman ga aikin low-temperature. Ƙananan suction temperatures na iya ƙara compression ratio da discharge temperature, suna ƙara nauyi a kan compressor da lubricant. Kada a ɗauka cewa model da ya dace da medium-temperature refrigeration zai yi aiki cikin aminci a aikace-aikacen freezer.

Bayanan lantarki

Bayanan lantarki dole ne su dace da wutar lantarkin da ake da ita da kuma sarrafawar tsarin. Kwatanta:

• Ƙimar ƙarfin lantarki da zangon ƙarfin lantarki
