Mfundo zazikuluzikulu posankha screw chiller

1. Chigawo chachikulu chowongolera cha screw chiller ndi coefficient of performance of firiji, mphamvu ya firiji yoyesedwa pamene ikugwira ntchito, mphamvu yolowera ndi mtundu wa refrigerant pamene ikugwiritsidwa ntchito, ndi zina zotero.

2. Pamlingo wakutiwakuti, kusankha kwa screw chiller kuyenera kuganiziridwa molingana ndi katundu wozizirira ndikugwiritsa ntchito. Kwa makina a firiji omwe ali ndi ntchito yocheperako komanso nthawi yayitali yogwirira ntchito, mayunitsi a piston compressor amitundu yambiri kapena ma screw-type compressor ayenera kusankhidwa panthawi yogwira ntchito. Compressor unit ndiyosavuta kusintha ndikupulumutsa mphamvu.

3. Posankha zoziziritsa kukhosi, perekani patsogolo mayunitsi omwe ali ndi magwiridwe antchito apamwamba. Malinga ndi ziwerengero, avareji ya nthawi yogwira ntchito ya oziziritsa pa 100% katundu chaka chonse amawerengera zosakwana 1/4 ya nthawi yonse yogwira ntchito. Kuchuluka kwa 100%, 75%, 50%, ndi 25% nthawi yogwira ntchito panthawi yonse yogwira ntchito ndi pafupifupi 2.3%, 41.5%, 46.1%, ndi 10.1%.

Chifukwa chake, posankha zoziziritsa kukhosi, zitsogozo ziyenera kuperekedwa kwa zitsanzo zokhala ndi mapindikira osalala bwino. Pa nthawi yomweyo, katundu kusintha osiyanasiyana chiller ayenera kuganiziridwa popanga ndi kusankha.
