Kuyerekeza katatu kwa refrigerant R410A R32 R290

Kuyerekeza pakati pa R32 ndi R410A

1. Voliyumu yolipira ya R32 ndiyocheperako, nthawi 0.71 yokha ya R410A. Kuthamanga kwa ntchito ya R32 dongosolo ndipamwamba kuposa R410A, koma kuwonjezeka kwakukulu sikuposa 2.6%, zomwe ndi zofanana ndi zofunikira za R410A dongosolo. Panthawi imodzimodziyo, kutentha kwa mpweya wa R32 ndikokwera kuposa R410A Kukwera kwakukulu ndi 35.3 ° C.

2. Mtengo wa ODP (mtengo womwe ungathe kuwononga ozoni) ndi 0, koma mtengo wa GWP (mtengo wa kutentha kwapadziko lonse) wa R32 firiji ndi wochepa. Poyerekeza ndi R22, chiŵerengero cha kuchepetsa mpweya wa CO2 chikhoza kufika 77.6%, pamene R410A ndi 2.5% yokha. Ndibwino kwambiri kuposa R410A refrigerant pochepetsa mpweya wa CO2.

3. Mafiriji onse a R32 ndi R410A sakhala ndi poizoni, pomwe R32 amatha kuyaka, koma pakati pa R22, R290, R161, ndi R1234YF, R32 ili ndi malire oyaka kwambiri otsika LFL (malire oyatsira otsika), omwe sangayaka. Komabe, akadali firiji yoyaka ndi kuphulika, ndipo pakhala ngozi zambiri m'zaka zaposachedwa, ndipo ntchito ya R410A imakhala yokhazikika.

4. Ponena za kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake ka anthu. Zotsatira zoyesera zikuwonetsanso kuti njira yoziziritsira yomwe imagwiritsa ntchito R32 ili ndi mphamvu yowonjezera pang'ono kuposa R410A. Kulingalira kwathunthu kwa R32 kuli ndi kuthekera kwakukulu kosintha R410A.

Kuyerekeza pakati pa R32 ndi R290

1. Voliyumu yolipira ya R290 ndi R32 ndi yaying'ono, mtengo wa ODP ndi 0, mtengo wa GWP ndi wochepa kwambiri kuposa R22, mlingo wa chitetezo wa R32 ndi A2, ndipo mlingo wa chitetezo wa R290 ndi A3.

2. R290 ndiyoyenera kwambiri pamakina oziziritsa mpweya komanso kutentha kwambiri kuposa R32. Mapangidwe osagwirizana ndi R32 ndi apamwamba kuposa a R290. Kutentha kwa R32 ndikotsika kwambiri kuposa kwa R290. Mtengo wopangira chitetezo ndi wotsika.

3. Kukhuthala kwamphamvu kwa R290 kumakhala kochepera R32, ndipo kutsika kwamphamvu kwa makina ake osinthira kutentha kumakhala kochepa kuposa R32, zomwe zimathandizira kukonza magwiridwe antchito.

4. R32 unit voliyumu yoziziritsa mphamvu ndi pafupifupi 87% kuposa R290. Dongosolo la R290 liyenera kugwiritsa ntchito kompresa yokulirapo yosunthira pansi pafiriji yomweyi.

5. R32 ili ndi kutentha kwapamwamba kwambiri, ndipo kupanikizika kwa dongosolo la R32 kuli pafupi ndi 7% kuposa dongosolo la R290, ndipo mphamvu yowonjezera mphamvu ya dongosololi ndi pafupifupi 3.7%.

6. Kutsika kwapakati kwa R290 system heat exchanger ndi zosakwana R32, zomwe zimathandiza kukonza machitidwe. Komabe, kuyaka kwake ndikokulirapo kuposa R32, ndipo ndalama zopangira chitetezo ndizokwera kwambiri.
