Kev tsim qauv hluav taws hauv chav huv yuav tsum xav txog qhov yuav tsum tau ua ntawm ib puag ncig huv si thiab cov cai tswjfwm kev nyab xeeb hluav taws. Yuav tsum tau ua tib zoo saib xyuas kom tsis txhob muaj kuab paug thiab zam kev cuam tshuam ntawm huab cua, thaum ua kom muaj kev teb hluav taws sai thiab zoo.
1. Kev xaiv cov tshuab tua hluav taws
Cov tshuab hluav taws roj
HFC-227ea: siv ntau, tsis ua rau hluav taws xob, tsis muaj cov khoom seem, zoo rau cov khoom siv hluav taws xob, tab sis yuav tsum xav txog qhov airtightness (chav huv uas tsis muaj plua plav feem ntau kaw zoo).
IG-541 (roj inert): tsis ua rau ib puag ncig puas tsuaj thiab tsis muaj tshuaj lom, tab sis xav tau qhov chaw cia khoom loj dua.
Lub kaw lus CO₂: siv nrog kev ceev faj, tej zaum yuav ua rau cov neeg ua haujlwm raug mob, thiab tsuas yog tsim rau thaj chaw tsis muaj neeg saib xyuas.
Cov xwm txheej siv tau: chav hluav taws xob, thaj chaw ntsuas qhov tseeb, cov chaw khaws ntaub ntawv thiab lwm qhov chaw uas ntshai dej thiab kuab paug.
Lub tshuab txau dej tsis siv neeg
Lub tshuab txau dej ua ntej: cov kav dej feem ntau yog inflated nrog roj, thiab thaum muaj hluav taws, nws raug tso tawm ua ntej thiab tom qab ntawd puv nrog dej kom tsis txhob muaj kev txau thiab ua qias tuaj (pom zoo rau cov chav huv).
Tsis txhob siv cov tshuab ntub dej: cov kav dej puv nrog dej ntev heev, thiab qhov kev pheej hmoo ntawm kev xau dej siab heev.
Kev xaiv nozzle: cov khoom siv hlau tsis xeb, tiv taus plua plav thiab tiv taus xeb, kaw thiab tiv thaiv tom qab kev teeb tsa.
Lub tshuab ua pa dej siab
Kev txuag dej thiab kev tua hluav taws zoo, tuaj yeem txo cov pa luam yeeb thiab hmoov av hauv zos, tab sis qhov cuam tshuam rau kev huv yuav tsum tau txheeb xyuas.
Kev teeb tsa lub tshuab tua hluav taws
Nqa Tau Yooj Yim: CO₂ lossis tshuaj tua hluav taws hmoov qhuav (muab tso rau hauv chav kaw cua lossis txoj kev hauv tsev kom tsis txhob nkag mus rau hauv thaj chaw huv).
Lub thawv tua hluav taws uas muab tso rau hauv: txo cov qauv uas tawm los kom tsis txhob muaj hmoov av sib sau ua ke.
2. Tsim kom muaj kev hloov pauv ib puag ncig uas tsis muaj plua plav
Kev kaw cov kav dej thiab cov khoom siv
Cov kav dej tiv thaiv hluav taws yuav tsum tau kaw nrog epoxy resin lossis cov tes tsho stainless hlau ntawm phab ntsa kom tiv thaiv cov khoom me me xau.
Tom qab kev teeb tsa tiav lawm, cov dej txau, cov ntsuas pa luam yeeb, thiab lwm yam yuav tsum tau tiv thaiv ib ntus nrog cov npog plua plav thiab tshem tawm ua ntej tsim khoom.
Cov ntaub ntawv thiab kev kho qhov chaw
Cov kav dej hlau tsis xeb lossis cov kav dej galvanized raug xaiv, nrog cov chaw du thiab yooj yim los ntxuav kom tsis txhob muaj hmoov av.
Cov li qub, cov thawv, thiab lwm yam yuav tsum tau ua los ntawm cov khoom uas tsis yaj thiab tiv taus xeb.
Kev sib raug zoo ntawm lub koom haum cua ntws
Qhov chaw ntawm cov khoom siv ntes pa luam yeeb thiab cov nozzles yuav tsum tsis txhob muaj lub thawv hepa kom tsis txhob cuam tshuam rau qhov sib npaug ntawm huab cua.
Yuav tsum muaj ib txoj kev npaj tso pa tawm tom qab tso cov tshuaj tua hluav taws tawm kom tiv thaiv cov roj tsis txav.
3. Lub tshuab ceeb toom hluav taws
Hom ntes
Lub tshuab ntes pa luam yeeb (ASD): Nws kuaj pa los ntawm cov kav dej, muaj kev rhiab heev, thiab tsim nyog rau cov chaw muaj cua ntsawj ntau.
Lub tshuab ntes pa luam yeeb/kub hom taw tes: Nws yog qhov tsim nyog los xaiv tus qauv tshwj xeeb rau cov chav huv, uas yog cov plua plav-pov thawj thiab tiv thaiv hluav taws xob.
Lub tshuab ntes nplaim taws: Nws yog qhov tsim nyog rau cov kua dej lossis cov roj uas yooj yim hlawv (xws li cov chav khaws tshuaj lom neeg).
Kev sib txuas ntawm lub tswb ceeb toom
Lub teeb liab hluav taws yuav tsum txuas nrog kom kaw lub tshuab cua tshiab (kom tiv thaiv cov pa luam yeeb tsis txhob kis mus), tab sis lub luag haujlwm ntawm cov pa luam yeeb yuav tsum tseem khaws cia.
Ua ntej pib lub tshuab tua hluav taws, lub tshuab tua hluav taws yuav tsum kaw cia kom paub tseeb tias qhov kev tua hluav taws muaj zog.
4. Cov pa luam yeeb thiab kev tiv thaiv pa luam yeeb thiab kev tsim cov pa luam yeeb
Lub tshuab pa luam yeeb
Qhov chaw ntawm qhov chaw tso pa tawm yuav tsum zam thaj chaw tseem ceeb ntawm thaj chaw huv si kom txo tau kev ua qias tuaj.
Cov kav dej pa luam yeeb yuav tsum muaj lub tshuab ua kom hluav taws kub (fused thiab kaw ntawm 70 ℃), thiab cov khoom siv rwb thaiv tsev sab nraud yuav tsum tsis txhob tsim hmoov av.
Kev tswj siab zoo
Thaum tua hluav taws, tua qhov cua, tab sis tswj kom muaj qhov siab me ntsis hauv chav buffer kom tiv thaiv cov pa phem sab nraud kom tsis txhob nkag mus.
5. Cov Lus Qhia thiab kev lees txais
Cov qauv tseem ceeb
Cov lus qhia Suav: GB 50073 "Cov Lus Qhia Txog Kev Tsim Chav Huv", GB 50016 "Cov Lus Qhia Txog Kev Tiv Thaiv Hluav Taws Hauv Tsev", GB 50222 "Cov Lus Qhia Txog Kev Tiv Thaiv Hluav Taws Hauv Tsev Sab Hauv".
Cov ntaub ntawv siv thoob ntiaj teb: NFPA 75 (Kev Tiv Thaiv Khoom Siv Hluav Taws Xob), ISO 14644 (Tus Qauv Chav Huv).
Cov ntsiab lus txais
Kev sim tshuaj ntsuam xyuas cov tshuaj tua hluav taws (xws li kev sim tshuaj tsuag heptafluoropropane).
Kev kuaj qhov xau (kom paub tseeb tias cov kav dej / cov qauv kaw tau kaw).
Kev sim txuas (lub tswb ceeb toom, cua txias txiav tawm, pa luam yeeb pib, thiab lwm yam).
6. Kev ceev faj rau cov xwm txheej tshwj xeeb
Chav huv si ntawm cov khoom siv roj ntsha: tsis txhob siv cov tshuaj tua hluav taws uas yuav ua rau cov khoom siv roj ntsha puas tsuaj (xws li qee cov hmoov qhuav).
Chav huv si hluav taws xob: muab qhov tseem ceeb rau cov tshuab tua hluav taws uas tsis muaj hluav taws xob kom tiv thaiv kev puas tsuaj los ntawm hluav taws xob.
Thaj chaw tiv thaiv kev tawg: ua ke nrog kev tsim cov khoom siv hluav taws xob tiv thaiv kev tawg, xaiv cov khoom siv ntes kev tawg.
Kev xaus lus thiab cov lus qhia
Kev tiv thaiv hluav taws hauv cov chav huv si xav tau "kev tua hluav taws zoo + kev ua qias tuaj tsawg". Kev sib xyaw ua ke pom zoo:
Cov khoom siv tseem ceeb: HFC-227ea roj tua hluav taws + kev ntes pa luam yeeb.
Thaj chaw dav dav: cov tshuaj tsuag ua ntej ua haujlwm + lub tshuab ntes pa luam yeeb hom taw tes.
Txoj kev hauv tsev/tawm: lub tshuaj tua hluav taws + lub tshuab tso pa tawm.
Thaum lub sijhawm tsim kho, yuav tsum muaj kev koom tes nrog HVAC thiab cov kws tshaj lij kho kom zoo nkauj kom ntseeg tau tias muaj kev sib txuas zoo ntawm cov chaw tiv thaiv hluav taws thiab cov kev xav tau huv.
