R32 Refrigerant Parameters thiab Daim Ntawv Thov
Qhov txawv ntawm R32 refrigerant thiab R410A refrigerant
Piv nrog R410A, qhov saturation siab ntawm R32 yog kwv yees li 3 feem pua siab dua, qhov tso cua sov yog 8-15 degrees siab dua, lub zog yog 3-5 feem pua siab dua, thiab lub zog efficiency piv yog li 5 feem pua.
1. R32 yog flammable, tab sis tsis-flammable gas, tsis muaj xim, tsis muaj xim thiab pob tshab kua nyob rau hauv ib txwm kub thiab siab;
2. R32 yooj yim yaj hauv cov roj, tab sis nyuaj rau yaj hauv dej;
3. Cov tshuaj toxicity ntawm R32, R22, R410A, thiab R290 tag nrho yog nyob rau qib A kev nyab xeeb;
4. Lub ignition kub ntawm R32 yog 648 degree, lub sab sauv txwv ntawm combustion yog 33.4 feem pua, thiab lub qis txwv ntawm combustion yog 12.7 feem pua;
5. Lub ntim ntim ntawm R32 system yog tsawg dua li ntawm R10A system.
Yuav ua li cas kho qhov flammability ntawm R32 refrigerant?
1. Qib kev ruaj ntseg.
Cov txheej txheem thoob ntiaj teb ISO817 thiab ISO5149 tau txhais cov qib R32 kev nyab xeeb raws li A2L, uas yog, cov nplaim hluav taws kub qis dua li A2.
Lus Cim: 1. Qib combustion yog: 1-tsis-flammable; 2 - Flammable; 3 - nplaim taws heev; 2L - me ntsis flammable; 2. Nyiv txhais R32 refrigerant raws li ib tug tsis-flammable refrigerant;
2. Tus nqi them ntawm R32 yog tsawg dua li ntawm R410A.
3. Plaub qhov tsim nyog yuav tsum tau ua raws li R32 combustion
4. Ignition qhov chaw ntawm R32 refrigerant
5. Sustainability ntawm combustion ntawm R32 refrigerant
Kev ceev faj rau daim ntawv thov khoom R32
1. Yog tias koj yuav tsum tau ua kom ntev lub raj tooj liab, koj yuav tsum tau siv lub raj tooj liab uas muaj tuab tuab dua lossis sib npaug ntawm 0.8 hli;
2. Ua tib zoo saib xyuas qhov sib txawv ntawm cov yeeb nkab txoj kab uas hla ntawm kev teeb tsa thiab kev xaim thiab R22 refrigerant;
3. Lub tsev nyob sab hauv thiab cov yeeb nkab txuas yuav tsum tau nqus thiab tswj xyuas kom tsis txhob muaj qhov xau hauv qhov system, thiab daim ntawv ntawm kev tshem tawm tsis raug tso cai los hloov lub tshuab nqus tsev;
4. Rau cov kav hlau txuas ntxiv, nws yuav tsum tau ntxiv cov tub yees raws li qhov xwm txheej:
Thaum cov yeeb nkab txuas tsawg dua lossis sib npaug li 8m, tsis tas yuav ntxiv cov tub yees ntxiv. Yog tias cov yeeb nkab txuas ntau tshaj 8m (raws li cov yeeb nkab ua kua), nws yuav tsum tau ntxiv cov tub yees rau txhua 1m tshaj 5m. Cov nplais hluav taws xob yuav tsum tau siv rau ntau qhov sib ntxiv, tsis pub ntxiv los ntawm kev xav lossis raws li qhov tsis xws li tam sim no thiab siab.
