Kada a ɗauka cewa kowane compressor na injin kankara MBP ne ba tare da duba kewayon aikace-aikace, refrigerant da ƙimar capacity ba.

Abubuwan la’akari wajen sayen MBP compressors

Ga masu rarrabawa da kamfanonin gyara, buƙatar maye gurbin MBP sau da yawa tana bambanta saboda beverage coolers, display cases da commercial refrigerators suna da bambance-bambancen ƙira sosai. Kafin yin oda, duba cooling capacity a yanayin evaporating da condensing da ya dace, ba wai nominal horsepower kawai ba.

Hakanan yana da muhimmanci a daidaita dacewar refrigerant da oil. Compressor da aka ƙera don wani refrigerant ba zai iya amfani kai tsaye da wani ba. Ko da inda akwai zaɓuɓɓukan retrofit, dole ne a duba system design, oil type, expansion device da performance data da kyau.

Ma’anar HBP Compressor da Aikace-aikace na Yau da Kullum

HBP compressor, ko high back pressure compressor, ana amfani da shi don aikace-aikace masu suction pressure mafi girma da evaporating temperature mafi girma. Misalan da aka fi sani su ne air-conditioning systems da wasu kayan aiki da aka ƙera don comfort cooling ko makamantan kewayon zafi.
