Kutentha Kwambiri.Absorption Chiller

Kufotokozera Zazikulu:

Mfundo yogwira ntchitoKutuluka kwamadzimadzi ndi njira yosinthira ndi kuyamwa kutentha.M'munsi kuthamanga, m'munsi evaporation.Mwachitsanzo, pansi pa mphamvu ya mpweya umodzi, kutentha kwa madzi ndi 100 ° C, ndipo pa 0.00891 mpweya wa mpweya, kutentha kwa madzi kumatsika kufika pa 5 ° C.Ngati malo otsika kwambiri amatha kukhazikitsidwa ndipo madzi amagwiritsidwa ntchito ngati sing'anga ya evaporation, madzi otsika otentha omwe ali ndi kutentha kwa machulukidwe ofanana ndi kupanikizika kwamakono angapezeke.Ngati madzi amadzimadzi amatha kuperekedwa mosalekeza, ndipo kupanikizika kochepa kungathe kusungidwa mokhazikika, madzi otsika otentha a kutentha kofunikira akhoza kuperekedwa mosalekeza.LiBr mayamwidwe chiller, kutengera mawonekedwe a yankho la LiBr, amatenga kutentha kwa nthunzi, gasi, madzi otentha ndi zofalitsa zina monga gwero loyendetsa, ndikuzindikira kutuluka kwa nthunzi, kuyamwa, kutsekemera kwa madzi a refrigerant ndi njira yopangira njira yothetsera vuto la vacuum zipangizo, kotero kuti njira yochepetsera kutentha kwa madzi a firiji ipitirire.Izi zikutanthauza kuti ntchito yopitiliza kupereka madzi ozizira ozizira otsika oyendetsedwa ndi gwero la kutentha imatha kuchitika.

Zomwe zili pansipa ndi mbiri yakampani yathu.

ZINTHU ZONSE ZOTSATIRA

Mfundo yogwira ntchito ya kutentha kochepa.mayamwidwe chiller akuwonetsedwa mkuyu. 3.2-1.
Mpweya wa refrigerant wopangidwa ndi jenereta umakhazikika mu condenser mu mawonekedwe amadzi a refrigerant, omwe amaperekedwa kudzera mu chubu la U-mawonekedwe kupita kudontho la poto la evaporator.Zimatenga kutentha kwa madzi ozizira ndikuchepetsa kutentha kwake kuti zikhazikitse mtengo wake, kenako madzi a refrigerant amasanduka nthunzi kukhala nthunzi ndikulowa mu absorber.Pambuyo pa absorber nthunzi, yankho lokhazikika mu absorber limakhala losungunuka ndipo limatulutsa kutentha komwe kumachotsedwa ndi madzi ozizira kuti asunge mphamvu ya yankho.

The kuchepetsedwa njira kwaiye absorber amaperekedwa ndi yankho mpope kwa exchanger kutentha, kumene kutenthedwa ndiyeno kulowa jenereta.Mu jenereta, njira yowonongeka imatenthedwa ndi madzi otentha monga gwero la kutentha (lomwe limayenda mkati mwa chubu) mpaka kumalo otentha ndipo limapanga mpweya wa refrigerant.Pakalipano, njira yowonongeka imayikidwa mu njira yowonongeka, yomwe imabwera ku absorber kuti ibwereze njira yopitira panjinga monga pamwambapa.Madzi ozizira amagwiritsidwa ntchito kuchepetsa kutentha kwapakati mu absorber ndi condenser.Ikatenthedwa, imalumikizidwa ndi nsanja yozizirira ndikubwerera kugawo kuti iyendetse pambuyo pozizirira.

Izi zoziziritsa kukhosi zomwe zimagulitsidwa zimagwira ntchito bwino pogwiritsa ntchito madzi ozizira kuti azitentha bwino.Kuphatikiza apo, chozizira chotenthetsera chomwe chimagulitsidwa chidapangidwa kuti chiphatikizidwe mosasunthika ndi makina ozizirira omwe alipo.Pomaliza, chotenthetsera ichi chogulitsa chimatsimikizira magwiridwe antchito odalirika pogwiritsa ntchito njira yopitilira njinga.

ZINTHU ZOFUNIKA KWAMBIRI NDI NTCHITO

Kutentha kochepa.mayamwidwe chiller amapangidwa makamaka ndi zipangizo kutentha kuwombola (jenereta, condenser, evaporator, absorber, kutentha exchanger, ndi zina zotero), automatic purge chipangizo, vacuum mpope, yankho mpope, refrigerant mpope, 3-njira valavu galimoto ndi kabati magetsi.Izi zoziziritsa kukhosi zogulitsa zidapangidwa ndi zida zapamwamba kwambiri kuti zitsimikizire kuti zikuyenda bwino.Kuphatikiza apo, chotenthetsera chomwe chimagulitsidwa chimaphatikizanso zinthu zapamwamba monga chipangizo chodzitchinjiriza komanso pampu ya vacuum.Chozizira chotenthetsera chomwe chikugulitsidwa chimakhalanso ndi valavu yamoto ya 3-way motor ndi kabati yamagetsi kuti iziwongolera bwino komanso kudalirika.

Ayi.	Dzina	Ntchito
1	Jenereta	Imayika njira yowonongeka kuchokera ku chowotcha kutentha kukhala njira yowonongeka pogwiritsa ntchito madzi otentha kapena nthunzi ngati sing'anga.Pakalipano, mpweya wa refrigerant umapangidwa ndikuperekedwa ku condenser, ndi concentrated solution flow to absorber.
2	Condenser	Imatsitsimutsa mpweya wa refrigerant woperekedwa kuchokera ku jenereta m'madzi a refrigerant.Kutentha kopangidwa panthawi ya condensation kumachotsedwa ndi madzi ozizira. A rupture disk imayikidwa pa refrigerant water outlet ya condenser, idzagwira ntchito yokha pamene mphamvu ya unit ikukwera mosadziwika bwino, kuteteza unit kuti zisapitirire. ≈39.28mmHg
3	Evaporator	Amaziziritsa madzi ozizira kuti azizizira ndi madzi a mufiriji osungunuka ngati sing'anga.
4	Womwa	Njira yothira mu chowumitsira imatenga mpweya wa mufiriji woperekedwa kuchokera mu evaporator ndipo madzi ozizira amachotsa kutentha.
5	Chotenthetsera kutentha	Imabwezeretsanso kutentha kwa njira yoyikirapo mu jenereta, motero imakweza mphamvu ya thermodynamic coefficient.
6	Auto-purge chipangizo	Zida ziwirizi zimaphatikizana kupanga makina otsuka mpweya omwe amapopa mpweya wosasunthika mu unit, kuonetsetsa kuti unit ikugwira ntchito ndikuwonjezera moyo wautumiki.
7	Pampu ya vacuum
8	Pampu ya refrigerant	Amagwiritsidwa ntchito popereka ndi kupopera madzi mufiriji mofanana pa chubu choyendetsa kutentha cha evaporator.
9	Pampu ya jenereta	Kupereka njira kwa jenereta, anazindikira kufalitsidwa mkati unit.
10	Pampu yamadzi	Kupereka njira absorber, anazindikira mkati kufalitsidwa mu unit.
11	Refrigerant bypass valve	Yang'anirani kuchuluka kwa madzi mufiriji mu evaporator ndikutulutsa madzi a refrigerant panthawi yotseka ma unit.
12	Valve yotsekereza njira	Sinthani kuchuluka kwa madzi mufiriji mu evaporator
13	Density mita	Yang'anirani kuchuluka kwa madzi a refrigerant
14	3-way motor valve	Sinthani kapena kuletsa kulowetsedwa kwa madzi a gwero la kutentha
15	Control cabinet	Kuwongolera magwiridwe antchito a unit
