Kubwerera kwamadzi
1. Kwa dongosolo la firiji pogwiritsa ntchito valve yowonjezera, madzi obwereranso akugwirizana kwambiri ndi kusankha ndi kugwiritsa ntchito molakwika valve yowonjezera.Kusankha kwakukulu kwa valve yowonjezera, kutsika kwazing'ono kwambiri, kuyika kosayenera kwa phukusi lomva kutentha kapena kuwonongeka kwa adiabatic packing. , kulephera kwa valve yowonjezera kungayambitse kubwerera kwamadzimadzi.
2. Kwa kachitidwe kakang'ono ka firiji pogwiritsa ntchito ma capillaries, kuchuluka kwa madzi owonjezera kumapangitsa kuti madzi abwerere. Pamene evaporator izizira kwambiri kapena fani yalephera, kutentha kwa kutentha kumakhala koipitsitsa. kubwerera.
Makina amayamba ndi madzi
Chochitika cha matuza kwambiri a mafuta opaka mafuta mu kompresa amatchedwa kuyamba ndi madzi.Kuphulika kwamadzimadzi pakuyamba kwamadzimadzi kumatha kuwonedwa momveka bwino mumayendedwe amafuta. Chifukwa chachikulu ndikuti firiji yambiri imasungunuka mafuta ophikira ndipo amamizidwa mu mafuta opaka.Kupanikizika kumatsika mwadzidzidzi, mwadzidzidzi kumawira.
Mafuta amabwerera
1. Pamene malo a compressor ndi apamwamba kuposa a evaporator, piritsi lobwereranso la mafuta loyima pa chitoliro chobwerera ndilofunika. Bweretsani kupindika mafuta molimba kwambiri kuti muchepetse kusungirako mafuta. , kuchuluka kwa bend yobwereranso mafuta ndi yayikulu, mafuta ena opaka mafuta ayenera kuwonjezeredwa.
2. Kuyambira pafupipafupi kwa kompresa sikuthandiza kuti mafuta abwerere. Chifukwa compressor inasiya kugwira ntchito kwa nthawi yochepa kwambiri, panalibe nthawi yopangira mpweya wokhazikika wothamanga mu chitoliro chobwerera, kotero kuti mafuta odzola amatha kungokhala. kutsalira mupaipi.Compressor idzatha mafuta ngati mafuta obwerera ali ochepa poyerekeza ndi mafuta othamanga.Nthawi yogwira ntchito ifupikitsa, payipi italikirapo, dongosololi limakhala lovuta kwambiri, vuto lalikulu la kubwerera kwa mafuta.
3. Kuperewera kwa mafuta kungayambitse kuchepa kwakukulu kwa mafuta.Chifukwa chachikulu cha kusowa kwa mafuta si kuchuluka ndi liwiro la compressor, koma mafuta oipa kubwerera kwa system.Installation ya mafuta olekanitsa akhoza mwamsanga kubwerera mafuta, kuwonjezera kompresa kuthamanga nthawi popanda mafuta kubwerera.
Evaporation kutentha
Kutentha kwa evaporation kumakhudza kwambiri firiji.Nthawi iliyonse ikachepa ndi digiri ya 1, kuzizira kofananako kumafunika kuwonjezera mphamvu ndi 4%.Choncho, ndizopindulitsa kuonjezera kuzizira kwa mpweya wozizira powonjezera kutentha kwa evaporation moyenerera pansi pa chikhalidwe chololeza.
Kutsitsa mwakhungu kutentha kwa evaporation kumatha kuziziritsa kusiyana kwa kutentha, koma kuchuluka kwa kuziziritsa kwa kompresa kumachepetsedwa, kotero kuthamanga kwa firiji sikungothamanga kwambiri.Kuphatikizansopo, kutsika kwa kutentha kwa evaporation, kutsika kozizira kozizira, koma katundu wawonjezeka, Kutalikirana kwa nthawi yothamanga, kumapangitsa kuti magetsi azikwera kwambiri.
Kutentha kwambiri kwa utsi
Zifukwa za kutentha kwapamwamba kwambiri ndi izi: kutentha kwakukulu kobwerera, kutentha kwakukulu komwe kumawonjezeredwa ndi galimoto, kuthamanga kwapamwamba, kuthamanga kwapamwamba, kutentha kwa adiabatic index ya refrigerant, kusankha kosayenera kwa refrigerant.
Mphamvu yamadzimadzi
1. Pofuna kuonetsetsa kuti compressor ikugwira ntchito bwino ndikuletsa kuchitika kwa kugwedezeka kwamadzimadzi, kutentha kwa mpweya kumafunika kukhala kochepa kwambiri kuposa kutentha kwa evaporation, ndiko kuti, kutentha kwakukulu kumafunika.
2. Kutentha kwa mpweya kuyenera kukhala kokwera kwambiri kapena kutsika kwambiri. Kutentha kwapamwamba kwambiri, ndiko kuti, kutenthedwa kwambiri, kumayambitsa kutentha kwa compressor. mu evaporator, amene osati amachepetsa kutentha kuwombola dzuwa la evaporator, komanso zimapanga madzi mantha kompresa.Kuyamwa kutentha muzochitika bwino ayenera kukhala 5 ~ 10 ℃ apamwamba kuposa kutentha evaporation.
Fluorine
Pakakhala fluoride pang'ono kapena kupanikizika kwake komwe kumawongolera kumakhala kochepa (kapena kutsekedwa pang'ono), chophimba cha valve cha valavu yowonjezera (mavuvu) kapena ngakhale cholowera cha valve chidzazizira. , maonekedwe a valavu yowonjezera sichimayankha, kutulutsa mpweya pang'ono kokha kumamveka.
Onani kumapeto kwa ayezi kuyambira, kuchokera pamphuno kapena kuchokera ku compressor kubwerera ku trachea, ngati kuchokera pamphuno pali kusowa kwa fluorine, kuchokera ku compressor ndi fluorine yambiri.
Otsika kuyamwa kutentha
1. Kuchuluka kwa refrigerant kudzaza kwachulukidwe, kutenga gawo la voliyumu ya condenser ndikuwonjezera kuthamanga kwa condenser, ndipo madzi omwe amalowa mu evaporator amawonjezeka moyenerera. Madzi omwe ali mu evaporator sangathe kusungunuka kwathunthu, kotero kuti kompresa imayamwa mpweya. ndi dontho lamadzimadzi.Chotero, kutentha kwa payipi ya gasi yobwerera kumachepa, koma kutentha kwa evaporation kumakhalabe kosasintha chifukwa kupanikizika sikuchepa, ndipo kutentha kwakukulu kumachepa.
2. Valve yowonjezera imatsegulidwa kwambiri. Chifukwa chakumangirira kosasunthika kwa zinthu zomwe zimamva kutentha, malo ochepa okhudzana ndi chitoliro cha mpweya wobwerera, kapena malo osayenera olongedza a zinthu zowona kutentha popanda zipangizo za adiabatic, kutentha komwe kumayesedwa ndi zinthu zowona kutentha sikuli kolondola. ndi pafupi ndi kutentha kozungulira, komwe kumawonjezera kutseguka kwa kayendedwe ka valve yowonjezera ndikupangitsa kuti madzi azichuluka kwambiri.
Kutentha kwakukulu koyamwa
1. Mu dongosolo, kuchuluka kwa kudzaza kwa firiji sikukwanira, kapena valavu yowonjezera imatsegulidwa yaying'ono kwambiri, zomwe zimapangitsa kuti pakhale kufalikira kwa firiji ya dongosolo, ndipo mlingo wa refrigerant wa evaporator ndi wochepa ndipo kutentha kwakukulu ndi kwakukulu, kotero kutentha kwa kuyamwa kumakhala kwakukulu.
2. Chophimba cha fyuluta pa doko la valve yowonjezera chatsekedwa, kuchuluka kwa madzi omwe amaperekedwa mu evaporator sikukwanira, kuchuluka kwa madzi a firiji kumachepetsedwa, ndipo gawo la evaporator limakhala ndi nthunzi yotentha kwambiri, kotero kutentha kwakuya kumawonjezeka. .
3. Pazifukwa zina, kutentha kwa mpweya kumakhala kwakukulu kwambiri, monga kutentha koyipa kwa payipi ya mpweya wobwerera kapena chitoliro chotalika kwambiri, chomwe chingapangitse kutentha kwa mpweya kukhala wokwera kwambiri. ozizira, theka otentha.
Low Exhaust kutentha
Kuthamanga kwa mpweya kumakhala kochepa kwambiri, ngakhale kuti zochitika zake zimawonekera pamapeto othamanga kwambiri, koma chifukwa chake nthawi zambiri chimakhala kumapeto kwapansi.
1. Ice block kapena zonyansa za valve yowonjezera, chipika cha fyuluta, ndi zina zotero, zidzachepetsanso kuyamwa ndi kutulutsa mpweya; Kusakwanira kwa firiji;
2. Bowo la valve yowonjezera latsekedwa, ndipo kuperekedwa kwa madzi kumachepetsedwa kapena kuyimitsidwa.Panthawi imeneyi, kuyamwa ndi kuthamanga kwa mpweya kumachepetsedwa.
HERO-TECH Industrial water chiller
Ma compressor odziwika padziko lonse lapansi odziwika bwino komanso ma condenser apamwamba kwambiri komanso evaporator, amawonetsetsa kuti kuzizira kwambiri, kugwiritsa ntchito mphamvu zochepa, phokoso lochepa komanso moyo wautali wautumiki.
Evaporator yokulirapo ndi condenser imatsimikizira kuti chiller unit ikuyenda pansi pa 45ºC kutentha kozungulira kwambiri.
Makina owongolera a Microcomputer omwe amapereka kukhazikika kwa kutentha mkati mwa ± 1ºC.
Kusintha kwatsopano kwa evaporator-in-tank kumatsimikizira kutentha kwamadzi komwe kumaperekedwa, popeza evaporator imaziziritsanso thanki yokha, imachepetsanso kutentha kozungulira, ndikuwonjezera mphamvu.
