Chiyambi cha ntchito ya valavu yowonjezera ya chiller

Water chiller ndi mtundu wa zida zazikulu zamafiriji, zomwe zimagwiritsidwa ntchito popanga, ndipo zimagwiritsidwa ntchito kwambiri pokonza chakudya, electroplating, jekeseni akamaumba ndi mafakitale ena.

Dongosolo la firiji la chiller lili ndi zigawo zinayi zazikulu: valavu yowonjezera, kompresa, evaporator, ndi condenser.

Opanga zoziziritsa kukhosi ali ndi zaka zambiri zazaka zambiri pakupanga, kupanga ndi kugulitsa zoziziritsa kukhosi, kuphatikiza zoziziritsa kuziziritsa m’madzi, zoziziritsira mpweya, ndi zoziziritsa kukhosi.

Zopangira madzi ndi zomangira madzi oundana ndizomwe timagulitsa, ndipo makasitomala ambiri amabwera kuno makamaka.

Panthawiyi, wopanga chiller adzawonetsa ntchito zazikulu za valve yowonjezera mu chiller.

1. Valavu yowonjezera ya chiller imapangidwa ndi magawo atatu: thupi la valve, chitoliro chokwanira ndi sensa ya kutentha.

2. Babu yozindikira kutentha mu valavu yowonjezera ya chiller ili pa chitoliro chotulutsira cha evaporator, ndipo ntchito yake yayikulu ndikuzindikira kutentha kwa chitoliro chotulukira cha evaporator;

3. Chitoliro choyezera mu valavu yowonjezera ya chiller sichili kutali ndi babu yowunikira kutentha, ndipo imagwirizanitsidwa ndi thupi la valve kupyolera mu chitoliro chaching’ono, kuti apereke kupanikizika kwenikweni pa kutuluka kwa evaporator ndi kufunafuna moyenera.

Kutentha kwakukulu kwa valve yowonjezera kuyenera kusinthidwa moyenera kuti friji yokwanira ilowe mu evaporator ndikuletsa refrigerant yamadzimadzi kuti isalowe mu compressor. Zomwe zili pamwambazi ndizokhudza kuyambika kwa valve yowonjezera ya chiller.
