Propane tub yees R290

Refrigerant R290, los yog propane, yog ib tug natural hydrocarbon refrigerant uas tau ncaj qha los ntawm liquefied gas. Piv nrog Freon, ib qho khoom siv tub yees, ntuj R290 tsis muaj chlorine atoms hauv nws cov molecules, yog li nws tus nqi ODP yog xoom, thiab nws tsis muaj kev puas tsuaj rau txheej ozone. Tsis tas li ntawd, piv nrog HFC cov khoom uas tseem tsis muaj kev puas tsuaj rau cov txheej txheem ozone, GWP tus nqi ntawm R290 yog ze rau 0, thiab tsis muaj kev cuam tshuam rau lub tsev cog khoom.

R-290 refrigerant (refrigerant qib propane) alias R290, Suav lub npe 丙烷, Askiv lub npe propane, tshuaj formula C3H8. R290 yog hydrocarbon refrigerant - nws tsis ua rau cov txheej txheem ozone thiab muaj cov nyhuv tsev cog khoom me me. Nws yog ib puag ncig tus phooj ywg refrigerant hnub no. Los ntawm ib puag ncig kev pom, nws yog ib qho tseem ceeb heev rau qhov pib ntawm R290 refrigerant ntawm cov khoom siv tub yees tshiab thiab kev saib xyuas tom qab muag. Tsis muaj kev txwv rau kev siv cov chav kawm.

R290 (propane) yog ib tug tshiab ib puag ncig tus phooj ywg refrigerant, feem ntau yog siv nyob rau hauv central cua txias, cua kub twj tso kua mis cua txias, cua txias hauv tsev thiab lwm yam khoom siv tub yees me me. Txawm li cas los xij, vim muaj cov yam ntxwv tawg ntawm R290, qhov kev txhaj tshuaj yog txwv, thiab qib kev nyab xeeb yog A3.

Lub hom phiaj tseem ceeb ntawm R-290

Nws yog siv los hloov R22 thiab R502 tub yees hauv cov khoom siv tub yees txias; vim R290 yog nplaim taws, nws feem ntau tsuas yog siv rau hauv cov khoom siv tub yees uas tsis muaj qhov kub thiab txias nrog cov kua dej me me, lossis ua cov khoom siv ntawm cov khoom cua kub sib xyaw; R290 thiab sib xws nrog cov pa roj nplua nyeem.

R-290 cia thiab thauj

R-290 refrigerant steel lub tog raj kheej yog lub thawv ntim siab, thiab nws yog nplaim taws thiab tawg. Thaum khaws cia, nws yuav tsum khaws cia kom deb ntawm qhov hluav taws kub, qhov chaw tshav kub, thiab tshav ntuj ncaj qha. Nws yog feem ntau muab cia rau hauv ib qho chaw txias, qhuav thiab ventilated warehouse; nws yuav tsum tau maj mam loaded thiab unloaded thaum tuav. , tiv thaiv kev puas tsuaj rau cov khoom siv xws li lub tog raj kheej thiab cov li qub.

R290 phom sij:

Kev kis luv luv rau 1 feem pua ​​​​propane tsis ua rau cov tsos mob;

Kev nthuav tawm cov ntsiab lus qis dua 10 feem pua ​​tsuas tuaj yeem ua rau kiv taub hau;

Kev siv tshuaj loog thiab tsis nco qab yuav tshwm sim thaum raug cov concentrations siab;

Tej zaum yuav ua rau asphyxiation ntawm raug rau cov concentrations siab heev.

Tsis tas li ntawd, R290 yog ib qho hluav taws xob hluav taws xob, thiab muaj kev phom sij ntawm kev sib tsoo thiab tawg thaum nws ntsib cov nplaim taws qhib los ntawm qhov chaw cua sov hauv qee qhov xwm txheej.

R290 tub yees muaj qhov zoo hauv qab no:

1. R290 refrigerant muaj thermal conductivity, ntau dua latent cua sov ntawm evaporation, me me molecular hnyav, zoo fluidity, qis tus me nyuam lub siab, thiab tsawg load ntawm lub compressor, uas yuav prolong lub neej kev pab cuam ntawm lub compressor. Siv R290 tub yees kom txuag hluav taws xob li ntawm 30 feem pua.

2. Cov tub yees ib txwm muaj xws li R22 thiab R410A tsis haum rau siv nyob rau hauv cov cheeb tsam kub kub, thaum R290 tub yees muaj qhov tshwj xeeb adaptability rau cov huab cua kub.
