Ester kumu aila no ka refrigerating compressors
Ester kumu aila no ka refrigerating compressors
ʻO Neopentyl saturated polyols nā ʻaila kumu e hoʻoheheʻe ʻia me ka HFC pahu hau.
He kūpono lākou no ka hoʻohana ʻana i nā compressors hoʻoheheʻe ʻana, gyro-type a rolling refrigeration compressors o R-134A, R-407C a me R-410A.
Loaʻa iā ia ke kūpaʻa wela maikaʻi, kūpaʻa hydrolysis, haʻahaʻa haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa coke, etc.
Hoʻokō nā ʻano hoʻolālā like ʻole i nā koi o ka miscibility kūpono o nā refrigerants like ʻole.

Nā ʻaila kumu no nā mea hoʻoheheʻe HCFC
ʻO nā huahana i loko o ka papaʻaina e kūpono i nā mea hoʻoheheʻe HCFC.
Hiki i nā huahana ke ho'onui i ka ikehu.
ʻO ke kūpono haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi a me ka volatility haʻahaʻa i ʻōlelo ʻia no nā compressors screw a me nā mea hānai.
