Amaphuzu abalulekile okukhethwa kwe-screw chiller

1. Ipharamitha yokulawula eyinhloko ye-screw chiller yi-coefficient yokusebenza kwesiqandisi, umthamo olinganiselwe wesiqandisi lapho usebenza, amandla okufaka kanye nohlobo lwesiqandisi uma sisetshenziswa, njll.

2. Ngokwezinga elithile, ukukhethwa kwama-screw chiller kufanele kucatshangelwe ngokuvumelana nomthwalo wokupholisa nokusetshenziswa. Kuzinhlelo zesiqandisi ezinomthwalo ophansi kanye nezimo zokusebenza ezinde, amayunithi we-compressor we-piston enamakhanda amaningi noma ama-screw-type compressor kufanele akhethwe ngesikhathi sokusebenza. Iyunithi ye-compressor kulula ukuyilungisa futhi yonge amandla.

3. Lapho ukhetha okokupholisa, nika kuqala amayunithi ane-coefficient ephezulu yokusebenza. Ngokusho kwezibalo, isikhathi esimaphakathi sokusebenza kwama-chillers ekulayisheni okungu-100% unyaka wonke senza ngaphansi kwe-1/4 yengqikithi yesikhathi sokusebenza. Izilinganiso zika-100%, 75%, 50%, kanye no-25% wesikhathi sokusebenza komthwalo phakathi nengqikithi yesikhathi sokusebenza cishe zingu-2.3%, 41.5%, 46.1%, kanye no-10.1%.

Ngakho-ke, lapho ukhetha ama-screw chiller, kufanele kunikezwe kuqala amamodeli anejika eliyisicaba elisebenza kahle. Ngesikhathi esifanayo, uhla lokulungiswa komthwalo we-chiller kufanele lucatshangelwe lapho uklama nokukhetha.
