Peb qhov kev sib piv ntawm cov tub yees R410A R32 R290

Kev sib piv ntawm R32 thiab R410A

1. Tus nqi ntim ntawm R32 tsawg dua, tsuas yog 0.71 npaug ntawm R410A. Kev ua haujlwm siab ntawm R32 system yog siab dua li ntawm R410A, tab sis qhov siab tshaj plaws nce tsis ntau tshaj 2.6%, uas yog sib npaug rau cov kev xav tau ntawm R410A system. Nyob rau tib lub sijhawm, qhov tso cua sov ntawm R32 system yog siab dua R410A Qhov siab tshaj plaws nce mus txog 35.3 ° C.

2. Tus nqi ODP (ozone-depleting muaj peev xwm tus nqi) yog 0, tab sis tus nqi GWP (lub ntiaj teb ua kom sov muaj peev xwm tus nqi) ntawm R32 refrigerant yog nruab nrab. Piv nrog R22, CO2 emission txo piv tuaj yeem ncav cuag 77.6%, thaum R410A tsuas yog 2.5%. Nws yog qhov zoo dua li R410A tub yees hauv kev txo qis CO2 emissions.

3. Ob qho tib si R32 thiab R410A cov tub yees tsis muaj tshuaj lom, thaum R32 yog cov nplaim taws, tab sis ntawm R22, R290, R161, thiab R1234YF, R32 muaj qhov siab tshaj plaws qis qis qis LFL (qis ignition limit), uas yog incombustible. Txawm li cas los xij, nws tseem yog ib qho hluav taws kub thiab tawg, thiab muaj ntau yam xwm txheej nyob rau xyoo tas los no, thiab kev ua haujlwm ntawm R410A yog qhov ruaj khov dua.

4. Nyob rau hauv cov nqe lus ntawm theoretical voj voog kev ua tau zoo, lub peev xwm txias ntawm R32 system yog 12.6% siab dua li ntawm R410A, lub zog siv tau nce 8.1%, thiab tag nrho lub zog txuag yog 4.3%. Cov txiaj ntsig kev sim kuj tseem qhia tau tias lub tshuab cua txias siv R32 muaj qhov sib piv ntawm lub zog siv hluav taws xob ntau dua li R410A. Kev xav txog ntawm R32 muaj peev xwm ntau dua los hloov R410A.

Kev sib piv ntawm R32 thiab R290

1. Lub ntim ntim ntawm R290 thiab R32 yog qhov me me, ODP tus nqi yog 0, GWP tus nqi kuj tseem tsawg dua R22, qib kev nyab xeeb ntawm R32 yog A2, thiab qib kev nyab xeeb ntawm R290 yog A3.

2. R290 yog haum rau nruab nrab thiab kub cua txias tshuab tshaj R32. Lub siab-resistant tsim ntawm R32 yog siab dua li ntawm R290. Lub flammability ntawm R32 yog qis dua li ntawm R290. Tus nqi tsim kev nyab xeeb yog tsawg.

3. Lub dynamic viscosity ntawm R290 yog tsawg dua R32, thiab lub siab poob ntawm nws lub cev kub exchanger yog tsawg dua R32, uas yuav pab txhim kho cov efficiency ntawm lub system.

4. R32 chav tsev ntim cua txias yog li 87% siab dua R290. R290 system yuav tsum siv lub tshuab hloov pauv loj dua nyob rau hauv tib lub tub yees.

5. R32 muaj qhov tso tawm ntau dua, thiab qhov sib piv siab ntawm R32 system yog kwv yees li 7% siab dua li ntawm R290 system, thiab tag nrho lub zog efficiency piv ntawm qhov system yog li 3.7%.

6. Lub siab poob ntawm R290 qhov hluav taws xob hloov hluav taws xob yog tsawg dua R32, uas pab txhim kho kev ua haujlwm ntawm lub cev. Txawm li cas los xij, nws qhov flammability ntau dua li R32, thiab kev nqis peev hauv kev tsim kev nyab xeeb yog siab dua.
