An Bayyana Compressors na LBP, MBP, da HBP ga Masu Sayen Kayan Gyaran Firiji

Ga masu sayen kayan gyaran firiji, ɗaya daga cikin dalilan da suka fi yawan jawo rashin dacewar compressor shi ne zaɓe bisa sunan na’ura kawai. Mai saya na iya neman “compressor na freezer,” “compressor na display case,” ko “compressor na beverage cooler,” amma waɗannan lakabobi ba sa wadatarwa koyaushe. Tambayar fasaha mafi muhimmanci ita ce ko an ƙera compressor ɗin ne don aiki da low, medium, ko high back pressure.

Rarrabuwar LBP MBP HBP compressor tana nuna maka kewayon pressure da evaporating temperature da aka ƙera compressor ɗin don jurewa.
