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.
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.
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 |
