1. Ka mea hoʻoheheʻe R22:
ʻO R22 kahi ʻano mahana, ʻo kona kumu hoʻolapalapa maʻamau o 40.8 ° C, liʻiliʻi loa ka solubility wai i ka R22, a hoʻoheheʻe ʻia ka ʻaila mineral kekahi i kekahi, ʻaʻole wela ʻo R22, ʻaʻole hoʻi i ka pahū, liʻiliʻi ka mea make, ʻoi loa ka hiki ke huli ʻo R22. ikaika, a paʻakikī ke loaʻa nā leaks.
Hoʻohana nui ʻia ʻo R22 i loko o nā ea, nā pā wela, nā dehumidifiers, nā mea hoʻomaloʻo refrigerating, ka mālama anuanu, nā lako meaʻai meaʻai, Marine refrigeration lako, ʻoihana refrigeration, pāʻoihana refrigeration, refrigeration units, supermarket hōʻike a hōʻike cabinets, etc.
2.Refrigerant R134A:
Loaʻa i ka R134a kahi paʻa kemika maikaʻi, akā naʻe, no ka mea hiki ke hoʻoheheʻe ʻia i ka wai, no laila ʻoi aku ka maikaʻi o ka ʻōnaehana refrigeration, ʻoiai inā he liʻiliʻi ka wai, ma lalo o ka hana o ka aila lubricating a pēlā aku, e hoʻopuka i kahi waikawa, carbon monoxide. , carbon dioxide a i ka metala corrosion hopena, a i 'ole "keleawe" hopena, no laila, na mea a pau ma luna o ka'ōnaehana o ka maloʻo a me ka maemae oi koi aku.
R134a, e like me ka 'ē aʻe refrigerant i R12, loaʻa haʻahaʻa loa toxicity a 'aʻole e lapalapa i ka lewa. nā mīkini, nā mīkini hau kalima, nā condensers maloʻo a me nā mea hana ʻē aʻe.
3.Refrigerant R404A:
Hoʻohana nui ʻia ʻo R404A e pani iā R22 a me R502.Loaʻa iā ia nā hiʻohiʻona o ka hoʻomaʻemaʻe, ka haʻahaʻa haʻahaʻa, ka wela ʻole a me ka hopena refrigeration maikaʻi. ʻO 0 kona ODP, no laila ʻo R404A kahi mea hoʻoheheʻe ʻaʻole e hoʻopau i ka papa ozone i ka lewa.
Hoʻokumu ʻia ʻo R404A me HFC125, hfc-134a a me hfc-143.He kinoea kala ole ia ma ka lumi wela a me ka wai alohilohi kala ole ma kona kaomi pono'ī. He kūpono no nā mea ho'ohehe'e pā'oihana hou, nā lako ho'ohu'a ka'a a me nā mea ho'olili ma waena a ha'aha'a.
4.Refrigerant R410A:
ʻO ke kaomi hana o R410A ma kahi o 1.6 mau manawa o ka ea R22 maʻamau, a he kiʻekiʻe ka maikaʻi o ka refrigeration (wela). a me carbon.R410A i kēia manawa i ʻike ʻia ma ke ao holoʻokoʻa ʻo ia ka refrigerant kūpono loa e pani i ka R22, a ua kaulana ʻia ma ʻEulopa, ʻAmelika, Iapana a me nā ʻāina ʻē aʻe.
Hoʻohana nui ʻia ʻo R410A e pani iā R22 a me R502.Loaʻa iā ia nā hiʻohiʻona o ka maʻemaʻe, haʻahaʻa haʻahaʻa, ʻaʻohe wela a me ka hopena refrigeration maikaʻi, a hoʻohana nui ʻia i nā ea ea hale, nā ea liʻiliʻi liʻiliʻi a me nā ea ea waena.
5.Refrigerant R407c:
ʻO R407C he chlorine-free fluorothane non-azeotropic i hui ʻia i ka refrigerant, colorless kinoea, mālama ʻia i loko o ka cylinder e like me ke kinoea hoʻoheheʻe ʻia. ʻaʻole centrifugal refrigeration system.I ka hoʻohana ʻia ʻana ma luna o ka mea hana R22 kumu, e hoʻololi ʻia nā ʻāpana a me ka ʻaila ʻaila o ka ʻōnaehana kumu.
Hoʻohana nui ʻia ʻo R407C e pani iā R22.Loaʻa iā ia nā ʻano o ka maʻemaʻe, haʻahaʻa haʻahaʻa, non-combustible a me ka hopena refrigeration maikaʻi.Ma lalo o ke kūlana o ka ea ea, ʻo ka nui o ka nui o ka refrigerating a me ka coefficient refrigeration he 5% ka haʻahaʻa ma mua o ka R22. Ma nā haʻahaʻa haʻahaʻa, ʻaʻole loli nui kona ʻano hoʻomaha, akā ʻo kona hiki ke hoʻomaha i kēlā me kēia leo he 20% haʻahaʻa.
6.Refrigerant R600a:
ʻO R600a kahi mea hoʻoheheʻe hydrocarbon hou me ka hana maikaʻi loa.Loaʻa ia mai nā mea kūlohelohe, ʻaʻole ia e hōʻino i ka papa ozone, ʻaʻohe hopena ʻōmaʻomaʻo a he ʻōmaʻomaʻo a me ke kaiapuni. ka hoʻohana mana, hoʻihoʻi lohi i ka loaʻa ʻana o ka temperature.Compatible me nā lubricants compressor like ʻole, he mea pani no R12.R600a he kinoea lapalapa.Hiki ke hoʻohui ʻia me ka ea e hana i kahi hui pahū. ʻO kahi hopena ʻino i ka hoʻopili ʻana me kahi oxidant. ʻOi aku ke kaumaha o ka mahu ma mua o ka ea a hiki ke palahalaha loa ma kahi haʻahaʻa.I ke ahi, e puhi ke kumu i ke ahi a e ʻā hou.
7.R32 mea ho'ohu'a:
Nui ka poʻe hana hoʻoluʻu makaʻu iā R32 ke kamaʻilio lākou e pili ana.He mea maʻamau ka pōʻino o kēia ʻano pahu hau.I nā manawa he nui, hiki i nā pōʻino palekana ke loaʻa i nā refrigerants. Ke hōʻike aku nei mākou inā pono e hoʻololi i nā ʻāpana no ka mālama ʻana i ka ʻōnaehana refrigeration, pono e holoi ʻia ma mua o ka hana.
Hoʻololi nui ʻo R32 iā R22, ʻo ia ke kinoea ma ka lumi wela a me ka wai aniani ʻaʻohe waihoʻoluʻu ma kona kaomi ponoʻī.He mea maʻalahi ka hoʻoheheʻe ʻana i ka ʻaila a me ka wai. ʻOiai ʻaʻohe ona ozone depletion hiki, he kiʻekiʻe kiʻekiʻe ka hoʻomehana honua, ʻo ia ka 550 mau manawa kiʻekiʻe ma mua o ka carbon dioxide i kēlā me kēia 100 makahiki.
ʻO ka coefficient hoʻomehana honua o R32 refrigerant he 1/3 o R410A, ʻoi aku ka maikaʻi o ke kaiapuni ma mua o ka R410A a me ka R22 refrigerant, akā ʻo R32 kekahi mau flammability. , 8-15 ℃ kiʻekiʻe wela wela, mana kiʻekiʻe, e pili ana i 3-5%, hiki ke hoʻohālikelike i ke kiʻekiʻe e pili ana i 5%; ʻO ke kiʻekiʻe kiʻekiʻe, ke kaomi hana kiʻekiʻe. Ma ke kūlana hana like a me ke alapine hana like me ka compressor, ka mana hoʻomaha. ʻO ka ʻōnaehana R32 ma kahi o 5% kiʻekiʻe ma mua o ka R410A refrigerant.
8.Refrigerant R717:
ʻO Ammonia ka mea hoʻohana nui ʻia ka mea hoʻoheheʻe ma waena o ka mahana wela. e like me 30 ℃ ma lalo o 1.5 MPa. Hoʻohana nui ʻia ia i ka refrigeration ʻoihana nui a me ka refrigeration pāʻoihana.
Maʻalahi e loaʻa, haʻahaʻa kumu kūʻai, haʻahaʻa haʻahaʻa, hoʻoluʻu ʻāpana nui, kiʻekiʻe exothermic coefficient, aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ʻaila, kahe liʻiliʻi, maʻalahi ke loaʻa i ka wā leakage. ma ke keleawe a me ke keleawe.
9.Refrigerant R290:
R290, propane, he hou kaiapuni refrigerant.Mainly hoʻohana 'ia no ke kikowaena ea ea, wela ea ea ea, hale a me na mea liilii refrigeration mea. hoʻohana ʻia e like me ka refrigerant e pani ai iā R22 a me R502, kūpono me ka ʻōnaehana kumu a me ka ʻaila lubricating, no ka ea ea waena, ka ea pā wela, ka ea hau hale a me nā mea hana liʻiliʻi liʻiliʻi.
Hōʻike nā hoʻokolohua ʻo ka nui o ka perfusion o R290 ma lalo o ka nui o ka ʻōnaehana like ma kahi o 43% o ka R22. No ka mea ʻoi aku ka liʻiliʻi o ka wela huna o ka vaporization o R290 ma kahi o ʻelua ʻelua o ka R22, ʻoi aku ka liʻiliʻi o ka holo ʻana o ka refrigerant o ka ʻōnaehana refrigeration me R290. Ke hoʻohana nei i ka refrigerant R290, hiki ke piʻi i ka 10-35% ka nui o ka mālama ʻana i ka ikehu. ke alo o ke kumu wela a me ke ahi hamama.
1. ʻOi aku ke kiʻekiʻe o ka evaporation pressure
ʻOi aku ka kiʻekiʻe o ke kaomi evaporation: inā ʻoi aku ka haʻahaʻa o ke kaomi evaporation o ka refrigerant ma mua o ke kaomi ea, ua maʻalahi ka ea e komo i loko o ka ʻōnaehana a paʻakikī ka ʻōnaehana.No laila, ua manaʻo ʻia e hiki ke kiʻekiʻe ke kaomi evaporation o ka refrigerant ma ka wela haʻahaʻa ma mua o ke kaomi lewa.
2. ʻOi aku ka nui o ka wela huna o ka evaporation
ʻOi aku ka nui o ka wela huna o ka hoʻohuhū: ʻoi aku ka nui o ka wela huna o ka vaporization o ka refrigerant, e hōʻike ana i ka nui o ka wela e hiki ke komo ma ka hoʻohana ʻana i ka mea hoʻomaha liʻiliʻi.
3. ʻOi aku ka kiʻekiʻe o ka mahana koʻikoʻi
Inā kiʻekiʻe ka mahana koʻikoʻi, e hōʻike ana he kiʻekiʻe ka mahana coagulation refrigerant, hiki ke hoʻomaloʻo ka refrigerant ma ka hoʻohana ʻana i ka ea a i ʻole ka wai e hoʻokō i ka hopena o ka condensation liquefaction.
4. He haʻahaʻa ke kaomi condensation
He haʻahaʻa ke kaomi coolant: he haʻahaʻa ke kaomi hoʻoluʻu, e hōʻike ana e hiki ke hoʻoheheʻe ʻia ka refrigerant me ka haʻahaʻa haʻahaʻa, a he liʻiliʻi ka compression ratio o ka compressor, hiki ke mālama i ka horsepower o ka compressor.
5. Pono e haʻahaʻa ka mahana solidification
He haʻahaʻa ka mahana maloʻo: haʻahaʻa ka wahi maloʻo o ka mea hoʻomaʻamaʻa, i ʻole e maloʻo ka mea hoʻoheheʻe i loko o ka evaporator a ʻaʻole hiki ke kaapuni.
6. ʻOi aku ka liʻiliʻi o ke kinoea hau ma mua o ka leo
ʻOi aku ka liʻiliʻi o ka nui kikoʻī o ka mea hoʻoluʻu kinoea: ʻoi aku ka liʻiliʻi o ka nui kikoʻī o ka mea hoʻoluʻu kinoea, ʻoi aku ka maikaʻi, ʻoi aku ka liʻiliʻi o ka leo o ka mea hoʻoemi hiki ke hoʻemi i ke kumukūʻai, a hiki i ka paipu hoʻoheheʻe a me ka paipu hoʻopau ke hoʻohana i ka paipu hoʻoheheʻe liʻiliʻi.
7.Liquid coolant he kiʻekiʻe kiʻekiʻe
ʻO ke kiʻekiʻe o ke kiʻekiʻe o ka mea hoʻoheheʻe wai, ʻoi aku ka kiʻekiʻe o ka mea hoʻoheheʻe wai, ʻoi aku ka liʻiliʻi o ka paipu.
8.Soluble i ka aila hau
Hiki ke hoʻoheheʻe ʻia i loko o ka ʻaila hau: ʻaʻole pono ka ʻōnaehana e hoʻokomo i ka mea hoʻokaʻawale aila.
9.Chemical paʻa
Paʻa kemika: e ʻokoʻa ka mahana evaporation me nā hoʻololi wela, e like me ka mahana evaporation o ka mīkini wai hau he 0 ~ 5 ℃, anu i loko o ka ʻōnaehana refrigeration, hoʻololi kino wale ka media anuanu, me ka ʻole o ka hoʻololi kemika, ʻaʻole decomposition.
10. ʻAʻohe corrosive
He nui ka latent wela o ka evaporation: non-corrosive i ke kila a me ka metala, a me ka amonia corrosive i copper.Good insulation, i ole ia e luku aku i ka compressor kaʻa insulation, no laila,ʻaʻole pono e hoʻohanaʻia ka amonia i loko o ka compressor pani, i mea e pale aku ai i ka pilina pololei. me ka wili keleawe.
11.Non – toxic non – combustible non – pahū
