Disadvantages Of Kaw -Loop Cooling Systems

 

 

Tus nqi pib nqis peev siab

Kaw- voj tshuab cua txias muaj cov qauv nyuaj dua li qhib- lub voj voog. Ntxiv rau cov khoom tseem ceeb xws li cov twj siv hluav taws xob thiab cov khoom siv hluav taws xob sib hloov, lawv xav tau cov cuab yeej pabcuam suav nrog cov tso tsheb hlau luam nthuav dav, ua- cov twj tso kua mis, ntsuas qhov ntsuas kub, thiab cov lim dej kom raug. Rau qee yam kev ua haujlwm,cua txias yees lossis chillers yuav tsum kuj raug ntsia raws li qhov chaw txias txias thib ob. Tus nqi ntawm kev yuav khoom, kev sib koom ua ke, kev teeb tsa, thiab kev ua haujlwm tau ntau dua li qhov qhib - lub voj voog. Rau me me thiab nruab nrab- cov lag luam me lossis qis-load txias qhov xwm txheej, tus nqi- kev ua tau zoo ntawm kev nqis peev thawj zaug yog qhov tsawg.

 

 

High System Kev Siv Hluav Taws Xob

Qhov nruab nrab cua txias hauv kaw- lub voj voog ncig hauv cov kav dej sib txuas, thiab cov cua sov hloov pauv nyob ntawm cov khoom siv hluav taws xob sib pauv los pauv cov cua sov nrog rau qhov chaw sab nraud. Lub tshav kub pauv efficiency yog qis dua piv rau cov tshuaj tsuag evaporation tshav kub dissipation ntawm qhib - voj tshuab. Txhawm rau kom ua kom txias tau zoo, cov twj tso kua mis yuav tsum tau nqa siab dua kom kov yeej cov kav dej thiab cov khoom siv hluav taws xob, siv hluav taws xob ntau dua thaum lub sijhawm ua haujlwm ntev -. Yog tias nruab nrog chillers, kev ua haujlwm tsis tu ncua ntawm compressors yuav ntxiv zog siv, ua rau cov nqi khiav lag luam ntau dua.

 

 

Kev kuaj mob tsis yooj yim thiab cov nqi kho mob siab

Txij li thaum lub kaw lus kaw tag nrho, kev ua haujlwm sab hauv ntawm cov kav dej thiab cov khoom siv tsis tuaj yeem pom ncaj qha. Thaum muaj teeb meem xws li kev xau nruab nrab, kev sib txuas ntawm cov khoom siv hluav taws xob, lossis kev tswj qhov kub thiab txias, cov cuab yeej tshaj lij xws li ntsuas ntsuas siab, ntsuas ntsuas kub, thiab ntsuas ntsuas ntws yuav tsum tau kuaj xyuas thiab qhov chaw, ua rau cov txheej txheem daws teeb meem nyuaj thiab sijhawm-siv. Tsis tas li ntawd, kev hloov cov khoom tsis zoo hauv cov cuab yeej tseem ceeb-xws li gaskets hauv phaj kub exchangers thiab diaphragms nyob rau hauv expansion tanks - yuav tsum tau kaw thiab disassembly, uas tsis tsuas cuam tshuam cov sij hawm ntau lawm tab sis kuj incurs nyiaj ntau yam kev tu thiab spare qhov chaw.

 

 

Cov kev xav tau nruj me ntsis rau nruab nrab thiab dej zoo

Txawm hais tias qhov nruab nrab hauv kaw - lub voj voog tsis yooj yim kis los ntawm lwm yam, kev tswj hwm nruj ntawm lub cev thiab tshuaj ntsuas ntawm qhov nruab nrab tseem tsim nyog. Thaum siv cov dej softened los yog cov coolants tshwj xeeb, tsis xws li pH tus nqi, conductivity, thiab xeb inhibitor concentration yuav tsum tsis tu ncua kuaj, nrog raws sij hawm nruab nrab replenishment los yog hloov los mus tiv thaiv pipeline corrosion los yog txo tshav kub exchangers ntawm tshav kub exchangers los ntawm nruab nrab degradation. Piv nrog rau qhov yooj yim ntawm kev ntxiv cov kais dej ncaj qha rau hauv qhib- lub voj voog, nruab nrab kev kho rau kaw- lub voj voog yog qhov nyuaj dua, thiab tus nqi ntawm cov khoom siv tshwj xeeb yog siab dua li cov tshuaj kho dej zoo tib yam.

 

 

Poor System Expansion Flexibility

Cov kev qhia tshwj xeeb ntawm cov kav dej, cov khoom siv hluav taws xob sib hloov, cov twj tso kua mis, thiab lwm yam khoom siv hauv kaw - lub voj voog txias yog tsim los ntawm kev ua kom txias txias, kom ntseeg tau tias muaj kev sib raug zoo tag nrho. Thaum cov txheej txheem ntau lawm tom qab raug hloov kho thiab qhov txias txias nce ntxiv, nws yog ib qho tsim nyog los hloov cov khoom siv tseem ceeb nrog cov kev qhia loj dua - xws li cov khoom siv hluav taws xob sib hloov thiab cov twj tso kua mis - lossis txawm rov tsim cov raj xa dej. Txoj kev nthuav dav thiab kev hloov kho yog qhov nyuaj thiab raug nqi, tsis tshua muaj kev hloov pauv ntau dua li qhib - lub voj voog, uas tuaj yeem ua tiav lub peev xwm nthuav dav los ntawm kev ntxiv cov cuab yeej xws li cua txias ntauwd kiv cua thiab cov twj tso kua mis.

 

 

 

Kev pheej hmoo ntawm kev khov thiab thaiv hauv qis- qhov kub thiab txias ib puag ncig

Nyob rau hauv qis - qhov kub thiab txias thaum lub caij ntuj no kaw, yog tias qhov nruab nrab cua txias hauv lub kaw lus tsis ntws tawm raws sijhawm thiab tsis muaj cov khoom siv hluav taws xob los yog cov khoom siv rwb thaiv tsev, qhov nruab nrab hauv cov kav dej yuav ua rau khov thiab nthuav dav, ua rau cov raj xa dej tawg, hloov pauv kub deformation, thiab lwm yam txhaum. Tshwj xeeb tshaj yog nyob rau sab qaum teb sab qaum teb, kev nqis peev ntxiv yog xav tau rau lub caij ntuj no tiv thaiv kev tiv thaiv kev tiv thaiv hauv kev kaw - lub voj voog, ua rau qhov nyuaj ntawm kev ua haujlwm thiab kev saib xyuas.
