Amanqaku aphambili okukhethwa kwe-screw chiller

1. I-parameter yolawulo oluphambili lwe-screw chiller yi-coefficient of performance of refrigeration, i-refrigeration capacity elinganisiweyo xa isebenza, amandla okufaka kunye nohlobo lwefriji xa lusetyenziswa, njl.

2. Ukuya kwinqanaba elithile, ukukhethwa kwe-screw chillers kufuneka kuthathelwe ingqalelo ngokomthwalo wokupholisa kunye nokusetyenziswa. Kwiinkqubo zefriji ezinomthwalo ophantsi kunye neemeko zokusebenza ezide, iiyunithi ze-compressor ze-piston ezininzi okanye i-screw-type compressors kufuneka zikhethwe ngexesha lokusebenza. Iyunithi yecompressor kulula ukuyilungisa kwaye ugcine amandla.

3. Xa ukhetha ii-chillers, zinike kuqala iiyunithi ezine-coefficient ephezulu yokusebenza. Ngokwezibalo, umyinge wexesha lokusebenza kwe-chillers kwi-100% yomthwalo unyaka wonke i-akhawunti engaphantsi kwe-1/4 yexesha elipheleleyo lokusebenza. Umlinganiselo we-100%, 75%, 50%, kunye ne-25% yexesha lokusebenza komthwalo ngexesha lexesha lokusebenza lilonke liqikelelwa kwi-2.3%, 41.5%, 46.1%, kunye ne-10.1%.

Ke ngoko, xa ukhetha i-screw chillers, kuqala kufuneka kunikwe iimodeli ezinegophe elithe tyaba elisebenzayo. Ngexesha elifanayo, uluhlu lohlengahlengiso lomthwalo we-chiller kufuneka luthathelwe ingqalelo xa uyila kwaye ukhetha.
