Economizer rau ZF Copeland Compressors

Copeland compressors ZF series high-powered machines raug muag ua ke nrog ib tug xov tooj ntawm cov khoom txuam, uas tau kawg tsis tau txhais hais tias koj yuav tsis tau ib lub tshuab. Cov cuab yeej txhawb nqa no muaj cov economizer, uas feem ntau hu ua phaj kub exchanger. Lub hauv paus ntsiab lus ua haujlwm ntawm kev lag luam yog dab tsi? Cia peb kawm txog nws.

Economizer yog cov khoom siv hluav taws xob sib hloov, los ntawm cov tub yees nws tus kheej throttling evaporation kom nqus tau cov cua sov kom lwm qhov ntawm cov tub yees kom tau subcooled. Nyob rau hauv lub evaporating kub yog qhov tsawg ({0}} degree los yog qis dua), lub voj voog economizer, tuaj yeem txhim kho kev ua haujlwm ntawm compressor compression tub yees lub voj voog, txhim kho lub peev xwm txias, txo qhov compressor tso cua sov.

Economizer rau fluorine yog lub tshuab ziab khaub ncaws qhuav, ib feem ntawm cov kua Freon yog throttled thiab evaporated nyob rau hauv lub raj thiab ces nkag mus rau lub compressor make-up gas chaw nres nkoj, thiab lwm qhov ntawm Freon kua yog subcooled sab nraum lub raj.

Lub tshav kub exchanger coj cov tub yees los ntawm cov kua pipeline thiab nthuav mus rau lub intermediate txhaj siab los ntawm lub expansion valve los pauv cov cua sov nrog cov kua nrog residual tshav kub refrigerant nyob rau hauv daim ntawv ntawm counterflow, thiab cov kua tawm hauv lub condenser tau subcooled. Lub superheated vapor tawm ntawm lub tshav kub exchanger thiab ces txhaj rau hauv qhov chaw nres nkoj economizer qhov twg nws sib tov nrog me ntsis compressed suction gas los ntawm lub evaporator ua ntej yuav ntxiv compressed.

Plhaub thiab raj, casing thiab phaj kub exchangers yuav siv tau. Lub peev xwm txias ntawm lub subcooler tuaj yeem muab tau los ntawm qhov sib txawv ntawm lub peev xwm txias nrog thiab tsis muaj kev lag luam. Qhov kub ntawm cov kua subcooled yuav tsum yog tsawg kawg yog 10 K siab tshaj qhov nruab nrab siab saturation kub.

Lub refrigerant subcooler yog tsim nyog nyob rau hauv lub compressor los tiv thaiv cov roj los yog kua rov qab los ntawm lub compressor los ntawm surging rau hauv lub compressor thaum kaw. Nyob rau hauv kev ua haujlwm tsis ruaj khov lossis thaum kaw lub subcooling Circuit Court, lub compressor yuav nyem qee cov roj tawm ntawm qhov chaw nres nkoj economizer, yog li cov kua tshuaj yuav tsum tau khoov mus rau hauv ntu nkhaus.
