Qhov sib txawv ntawm cov ntawv thov ntawm R22 thiab R134A

Qhov sib txawv ntawm cov ntawv thov ntawm R22 thiab R134A

1. Environmental Impact: R22 is a HCFC with strong ozone-depleting potential (ODP>0) thiab yog phased tawm hauv ntiaj teb; R134A yog HFC nrog tsis muaj ozone - Cov nyhuv tsis zoo (OVP}) tab sis muaj kev sov ntiaj teb sov sov muaj peev xwm (GWP).

2. Daim ntawv thov loj:

◦ R22: Kev lig kev cai siv hauv tsev tshuab cua txias, cov chillers me me, thiab hloov tshiab tau hloov los ntawm lwm txoj kev xaiv).

◦ R134A: Cov tub yees hauv cov tub yees, thiab ua lag luam khoom noj (haum rau nruab nrab- tsawg system).

3. Kev txuam nrog:

◦ R22: Tau tshaj nrog cov roj ntxhia; Ua haujlwm nrog cov roj hmab zoo tib yam.

◦ R134A: Yuav tsum muaj roj estertictic esterthetic (POE) lossis polyalkylene glycol roj (PAG); Xav tau EPDM / Viton Ntsaws Ruaj Ruaj (tsis sib xws nrog cov roj ntxhia thiab roj hmab zoo tib yam).

4. Thermodynamic Kev Ua Tau Zoo: R22 tau siab dua txias ua haujlwm ntawm nruab nrab kub; R134A muaj zog dua nyob rau hauv qis - qhov chaw ib puag ncig tab sis muaj qhov qis zog zog dua R22.

R22 yog ib qho ozone - deceting cov tub yees txias, feem ntau yog siv hauv cov tshuab ntxhia thiab chillers nrog roj ntxhia. R134A, ib qho ozone {{{4 4}} Tus phooj ywg tab sis siab} GWP lwm txoj hauv kev thiab tub yees, xav tau cov khoom siv hluavtaws thiab ntsaws ruaj ruaj.
