Pampu yotentha R152a

Kuti ikhale yosinthika ndi mphamvu zobiriwira komanso zatsopano, OSB inali itapereka mpope waposachedwa wa R152a.

Mutha kufunsa, R152a ndi chiyani?

Nazi mfundo zomwe zingakhale zothandiza pamalingaliro abwino.

R152a imagwiritsidwa ntchito kwambiri ngati chothandizira mu aerosols, ngati chotulutsa thovu, kapena ngati chigawo chazophatikiza za refrigerant, komabe, gulu lake ngati firiji yoyaka pang'ono yachepetsa kugwiritsidwa ntchito kwake mufiriji yamagalimoto ndi malonda. Komabe, misonkho yaposachedwa yaku Spain yamafiriji otenthetsera kutentha (okhala ndi GWP yoposa 150), komanso zoletsa zomwe zimakhazikitsidwa ndi lamulo la F-Gas poyang'anizana ndi kutentha kwa dziko, zadzetsa chidwi chatsopano mufiriji zoyaka moto, komanso ngakhale kwambiri. mafiriji oopsa monga ammonia.

Polyurethane kapena R152a ndi hydrocarbon yoyera ya fluoridate yokhala ndi mawonekedwe ofanana kwambiri ndi R134a. Ili ndi piritsi ya nthunzi yofanana ndi R134a, yopatuka kwa 2K yokha, ndipo ili ndi mawonekedwe ofanana ndi mankhwala, choncho imagwirizana ndi zipangizo zonse, zigawo za firiji, ma valve a thermostatic, compressors ndi mafuta opangira mafuta.

R152a ilinso ndi mawonekedwe apamwamba a thermodynamic ku R134a ndi Fossa. Kutentha kwa kutentha kwa refrigerant mu evaporators kumawonjezeka ndi pafupifupi 20% chifukwa cha thupi labwino la R152a poyerekeza ndi R134a. Chifukwa cha kutsika kwamphamvu kwa gasi, kutsika kwamphamvu kwa mizere yoyamwa kudzachepetsedwa ndi 30%. Kulemera kwa maselo otsika a R152a kumapereka kutentha kwakukulu kobisika kwa evaporation, mphamvu yapamwamba ya volumetric ya kompresa, ndi ntchito yabwino ya COP ya firiji, ndi kutentha kwapamwamba kwa pafupifupi 10K poyerekeza ndi R134a.

N'chifukwa chiyani tiyenera kutentha mpope R152a?

Popeza ndi yobiriwira komanso yotsika GWP, ilinso ndi malo otulutsira madzi otentha kwambiri poyerekeza ndi R32.

Ndipo ndiyabwino kusintha pampu ya R134a yotentha kwambiri.

Lumikizanani nafe pompano kuti mumve zambiri.
