Ireferensi esemgangathweni yereyithi yokutshintsha umoya kwiGumbi elicocekileyo

1. Kwiigumbi lokucocaimigangatho yamazwe ahlukeneyo, izinga lotshintshiselwano lomoya kwi-non-unidirectional flow cleanroom yezinga elifanayo alifani.

“IKhowudi yoYilo lweeNdawo zokusebenzela eziCocekileyo” (GB 50073-2001) yelizwe lethu icacisa ngokucacileyo izinga lokutshintsha komoya elifunekayo ekubaleni ukubonelelwa komoya ococekileyo kumagumbi acocekileyo okuqukuqela angenandlela enye kumanqanaba ahlukeneyo.Ukongeza, umgangatho wamazwe ngamazwe wokusingqongileyo kwilabhoratri yezilwanyana kunye nezibonelelo (GB14925-2001) umisela amaxesha angama-8 ~ 10/h kwi-enronment eqhelekileyo;10 ~ 20 amaxesha / h kwindawo yomqobo;20 ~ 50 amaxesha / h kwindawo ekwanti.

2. Iqondo lobushushu kunye nokufuma okuhambelanayo

Iqondo lokushisa kunye nokufuma okuhambelanayo kwigumbi lokucoca (indawo) kufuneka ihambelane nenkqubo yokuvelisa amayeza.Ukuba akukho mfuneko zikhethekileyo, iqondo lokushisa kufuneka lilawulwe kwi-18 ~ 26 ℃, kwaye ukushisa okuhambelanayo kufuneka kulawulwe kwi-45% ~ 65%.

3. Uxinzelelo olwahlukileyo

(1) Igumbi lokucoca kufuneka ligcine uxinzelelo oluthile, olunokuthi luphunyezwe ngokuvumela umthamo wokunikezelwa komoya omkhulu kunomthamo womoya wokukhupha, kwaye kufuneka kubekho isixhobo sokubonisa umahluko woxinzelelo.

(2) Umahluko we-static yoxinzelelo phakathi kwamagumbi akufutshane kumanqanaba ahlukeneyo ococeko lomoya kufuneka ube mkhulu kune-5Pa, uxinzelelo lwe-static phakathi kwegumbi lokucoca (indawo) kunye nomoya wangaphandle kufuneka ube mkhulu kune-10Pa, kwaye kufuneka kubekho isixhobo sokubonisa uxinzelelo. umahluko.

3Igumbi lokusebenza okanye indawo kunye nenkqubo yokuvelisa i-mocroorganisms ekucingelwa ukuba nayo nayiphi na imiphumo ye-pathogenic, kufuneka igcine uxinzelelo olubi olusuka kwigumbi elikufutshane.

4. Umthamo womoya omtsha

Umthamo othile womoya omtsha kufuneka ugcinwe kwigumbi lokucoca, kwaye ixabiso lawo kufuneka lithathe ubuninzi boku kulandelayo:

(1) I-10% ~ 30% yomthamo wokunikezelwa komoya opheleleyo kwigumbi elicocekileyo elingena-unidirectional, okanye i-2% ukuya kwi-4% yomthamo wokunikezelwa komoya wendlela enye yokucoca.

(2) Buyekeza Ubungakanani bomoya omtsha ofunekayo ekukhupheni kwangaphakathi kunye nokugcina uxinzelelo oluhle.

(3) Qinisekisa ubungakanani bomoya omtsha kumntu ngamnye ngeyure kwigumbi ungekho ngaphantsi kwama-40 m3.
