No ka hoʻonui ʻia ʻana me ka ʻōmaʻomaʻo a me ka ikehu hou, ua hōʻike ʻo OSB i ka paila wela hou loa R152a.
E nīnau paha ʻoe, he aha ka R152a?
Eia ka ʻike i hiki ke kōkua i ka manaʻo maikaʻi aʻe.
Hoʻohana mau ʻia ʻo R152a ma ke ʻano he mea hoʻolalelale i loko o nā aerosol, ma ke ʻano he mea hoʻohua, a i ʻole he ʻāpana o ka hui ʻana o ka refrigerant, akā naʻe, ʻo kona hoʻohālikelike ʻana ma ke ʻano he mea hoʻoheheʻe liʻiliʻi ua kaupalena ʻia kona hoʻohana ʻana i ka pahu hau kaʻa a me ke kālepa. Eia nō naʻe, ʻo ka ʻauhau Spanish hou o nā mea hoʻoheheʻe fluoridated greenhouse (me GWP ʻoi aku ka nui ma mua o 150), a me nā palena i kau ʻia e ka hoʻoponopono F-Gas i mua o ka hoʻomehana honua, ua alakaʻi i kahi hoihoi hou i nā refrigerants flammable, a ʻoi loa. nā mea hoʻohāinu ʻona e like me ka amonia.
ʻO ka Polyurethane a i ʻole R152a kahi hydrocarbon fluoridate maʻemaʻe me kahi ʻano like loa me R134a. Loaʻa iā ia kahi ʻāpana kaomi mahu e like me R134a, me nā deviations o 2K wale nō, a loaʻa nā ʻano kemika like, a no laila ua kūpono me nā mea āpau, nā ʻāpana refrigeration, nā kiwi thermostatic, compressors a me nā aila lubricating.
Loaʻa iā R152a nā hiʻohiʻona thermodynamic kiʻekiʻe ma mua o R134a a me Fossa. Hoʻonui ʻia ka coefficient hoʻoili wela o ka refrigerant i nā evaporator ma kahi o 20% ma muli o ka maikaʻi o nā waiwai kino o R152a i hoʻohālikelike ʻia me R134a. Ma muli o ka viscosity kinoea haʻahaʻa, e hoʻemi ʻia ka hāʻule o ke kaomi i nā laina suction e 30%. ʻO ka haʻahaʻa molekala kaumaha o R152a hāʻawi iā ia i kahi wela latent kiʻekiʻe o ka evaporation, kahi kiʻekiʻe volumetric pono o ka compressor, a ʻoi aku ka maikaʻi o ka COP hana o ka pōʻai refrigeration, me kahi kiʻekiʻe o ka hoʻokuʻu ʻana o ka mahana ma kahi o 10K i hoʻohālikelike ʻia me R134a.
No ke aha mākou e makemake ai i ka paila wela R152a?
ʻOiai he ʻōmaʻomaʻo a haʻahaʻa GWP, ʻoi aku ka nui o ka wai wela e hoʻohālikelike ʻia me R32.
A he kūpono ia e hoʻololi i ka R134a kiʻekiʻe wela wela.
E kelepona mai iā mākou i kēia manawa no ka ʻike hou aku.
