Chowumitsira Mpweya cha GA-HFB

Choumitsira mpweya mufiriji chimagwiritsa ntchito kutentha kochepa kwa evaporator ya refrigerating system, tiyeni tichepetse kutentha kwa mpweya wopanikizika, kenako tichotse madzi, kuti tipeze mpweya wouma wopanikizika; koma kuziziritsa mpweya wopanikizika sikutanthauza kuti madziwo adzatuluka, chifukwa madzi ambiri otsekedwa adzachotsedwa mu choumitsira mpweya mufiriji chifukwa cha kuyenda mofulumira kwa mpweya wopanikizika, zomwe zimapangitsa kuti pakhale kuchuluka kwa madzi ambiri kumapeto kwa ntchito;

Chowumitsira mpweya choziziritsa mpweya cha GA series ndi makina atsopano opangidwa kuti athetse vutoli. Chinthu chachikulu ndichakuti chowumitsira mpweya chopingasa chapangidwa ndi mawonekedwe olunjika osiyana. Pansi pa chowumitsira pali chipangizo choziziritsira champhamvu cha refrigerant, kapangidwe kake kosamala sikuti kamangopangitsa kuti makina oziziritsira azikhala olimba, mfundo ya mphamvu yokoka imagwiritsidwanso ntchito kupangitsa kuti madzi oundana akhale ovuta kunyamulidwa kuchokera ku chowumitsira mpweya ndi mpweya wopanikizika wothamanga chifukwa cha ubale womwe ulipo pakati pa mphamvu yokoka, kuti madzi oundana athe kutuluka kwathunthu.

Njira yoyenera yosankhira chowumitsira chozizira:
Pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito, kuchuluka kwa mpweya wa mitundu yonse ya makina owumitsa ozizira kudzakhala kosiyana. Kuti musankhe makina oyenera owumitsa ozizira, zinthu zisanu monga kuchuluka kwa mpweya wopanikizika, kuthamanga, kutentha kolowera, kutentha kwa malo ozungulira ndi malo ofunikira a mame opanikizika.

Chitsanzo: dzina la chipangizo choyezera mpweya limasonyeza kuti kuchuluka kwa utsi ndi 5.2m3 /min, kuthamanga kwa utsi ndi 0.8MPa, kutentha kwakukulu kwa utsi ndi 50℃, kutentha kwa chipinda cha makina ndi 38℃, ndipo malo ofunikira a dew ndi 10℃.

Kenako: mphamvu yogwiritsira ntchito makina owumitsa ozizira = 5.2 Nm3 /mphindi ÷ 0.75 ÷ 1.12 ÷ 1.0 = 6.2 Nm3 /mphindi
Chitsanzo chowumitsa chozizira chomwe chiyenera kusankhidwa ndi GA-50HFB.
