Nws ua haujlwm li cas
Hnub ci dej cua sov tshuab muaj xws li lub tank cia dej thiab hnub ci collectors. Muaj ob hom kev siv hluav taws xob hnub ci cua sov: ua haujlwm (nrog rau lub twj tso kua mis thiab tswj) thiab passive (tsis muaj lub twj tso kua mis thiab tswj).

Active Solar Water Heating Systems
Muaj ob hom active solar water heating systems:

Direct Circulation Systems
Lub twj tso kua mis tso dej hauv tsev los ntawm cov khoom ntim thiab mus rau hauv tsev. Lawv ua haujlwm zoo nyob rau hauv cov huab cua uas tsis tshua muaj cua sov.
Indirect Circulation Systems
Lub twj tso kua mis circulates ib qho dej hloov pauv tsis khov los ntawm cov khoom siv thiab cov khoom siv hluav taws xob. Qhov no heats cov dej ntws mus rau hauv tsev. Lawv yog cov nyiam nyob rau hauv cov huab cua uas muaj cua sov.

Illustration of an active, closed loop solar water heater. A large, flat panel called a flat plate collector is connected to a tank called a solar storage/backup water heater by two pipes. One of these pipes is runs through a cylindrical pump into the bottom of the tank, where it becomes a coil called a double-wall heat exchanger. This coil runs up through the tank and out again to the flat plate collector. Antifreeze fluid runs only through this collector loop. Two pipes run out the top of the water heater tank; one is a cold water supply into the tank, and the other sends hot water to the house.
Passive Solar Water Heating Systems
Passive solar water heating systems feem ntau tsis tshua kim tshaj li cov tshuab ua haujlwm, tab sis lawv feem ntau tsis tshua muaj txiaj ntsig. Passive systems muaj kev ntseeg siab dua thiab kav ntev dua, txawm li cas los xij. Muaj ob hom kev ua haujlwm passive:

Integral Collector-Storage Passive Systems
Cov tshuab no muaj lub tank ntim dej uas muaj cov khoom siv pob tshab kom lub hnub sov cov dej. Cov dej hauv lub tank ces ntws mus rau hauv cov kav dej. Cov tshuab no ua haujlwm zoo tshaj plaws nyob rau hauv qhov chaw uas qhov kub tsis tshua muaj qis qis qis qis. Lawv kuj tsim nyog rau cov tsev uas xav tau dej kub thaum nruab hnub thiab hmo ntuj.
Thermosyphon Systems
Cov dej yog rhuab nyob rau hauv lub ru tsev collector thiab ces ntws los ntawm ib tug system ntawm cov kav dej thaum lub kais dej kub qhib. Feem ntau cov tshuab no muaj peev xwm ntawm 40 nkas loos.

Illustration of a passive, batch solar water heater. Cold water enters a pipe and can either enter a solar storage/backup water heater tank or the batch collector, depending on which bypass valve is opened. If the valve to the batch collector is open, a vertical pipe (which also has a spigot drain valve for cold climates) carries the water up into the batch collector. The batch collector is a large box holding a tank and covered with a glaze that faces the sun. Water is heated in this tank, and another pipe takes the heated water from the batch collector into the solar storage/backup water heater, where it is then carried to the house.
Cia Tank thiab Solar Collectors
Feem ntau lub hnub ci dej rhaub dej yuav tsum muaj lub tank zoo insulated. Lub hnub ci cia tank muaj ib lub qhov hluav taws xob ntxiv thiab inlet txuas nrog lub collector. Hauv ob lub tank, lub hnub ci dej rhaub dej preheats cov dej ua ntej nws nkag mus rau hauv lub tshuab rhaub dej. Nyob rau hauv ib lub tank ib zaug, lub tshuab hluav taws xob thaub qab yog ua ke nrog lub hnub ci cia tank hauv ib lub tank.

Muaj peb hom solar collectors rau siv nyob hauv tsev:

Flat-phaj Collectors
Cov iav-phaj ntim khoom yog insulated, weatherproof thawv uas muaj ib tug tsaus absorber phaj nyob rau hauv ib los yog ntau tshaj iav los yog yas (polymer) npog. Unglassed flat-plate collectors (feem ntau yog siv rau hnub ci pas dej ua ke cua sov) muaj ib tug tsaus absorber phaj ua los ntawm hlau los yog polymer thiab tsis muaj cover los yog casing.
Integral Collector-Storage Systems
Kuj hu ua ICS lossis batch systems, lawv muaj ib lossis ntau lub tso tsheb hlau luam lossis cov kav dej hauv lub thawv iav insulated. Cov dej txias ua ntej dhau los ntawm cov khoom siv hnub ci, uas preheat cov dej. Cov dej tom qab ntawd txuas ntxiv mus rau lub tshuab hluav taws xob zoo li qub, muab cov dej kub ruaj khov. Lawv tsuas yog yuav tsum tau nruab rau hauv cov huab cua txias me me, vim cov kav dej sab nraum zoov tuaj yeem khov thaum huab cua txias heev.
Evacuated Tube Solar Collectors Evacuated Tube Solar Collectors
Feature ntshiab iav raj teem nyob rau hauv parallel. Txhua lub raj muaj lub iav sab nraud thiab lub raj hlau nqus hlau txuas nrog lub dab dej kub. Cov txheej ntawm lub dab dej kub absorbs hnub ci zog tab sis inhibits radiant tshav kub poob. Cov khoom siv no tau siv ntau dua hauv cov ntawv thov kev lag luam hauv Tebchaws Meskas.
Hnub ci dej cua sov tshuab yuav luag ib txwm xav tau ib hnub huab cua thaub qab

d lub sij hawm qhov kev thov nce. Cov pa tso dej tso cua sov feem ntau muab cov thaub qab thiab tej zaum twb yog ib feem ntawm lub hnub ci pob. Lub kaw lus thaub qab kuj tseem yog ib feem ntawm lub hnub ci sau, xws li lub tank saum ru tsev nrog lub thermosyphon system. Vim hais tias cov khoom khaws cia hauv ib qho chaw khaws cov dej kub ntxiv rau kev sau cov hnub ci, nws tuaj yeem ntim nrog lub tank tsis muaj dej los yog qhov xav tau ntawm lub rhaub dej raws li kev thaub qab.

Xaiv lub hnub ci dej rhaub
Ua ntej yuav thiab txhim kho lub hnub ci dej cua sov, koj yuav tsum ua cov hauv qab no:

Kwv yees tus nqi thiab kev siv hluav taws xob ntawm lub hnub ci dej cua sov
Ntsuam xyuas cov khoom siv hnub ci rau koj qhov chaw
Txiav txim siab qhov system loj
Tshawb xyuas cov cai hauv zos, cov lus cog tseg, thiab cov cai.
Kuj kawm txog ntau yam uas yuav tsum tau muaj rau lub hnub ci dej cua sov, nrog rau cov hauv qab no:

Hnub ci dej cua sov qhov system cua sov exchangers
Cov dej hloov hluav taws xob rau hnub ci dej cua sov tshuab
Txhim kho thiab tswj qhov system
Kev txhim kho kom zoo ntawm lub hnub ci dej rhaub dej yog nyob ntawm ntau yam. Cov yam tseem ceeb no suav nrog cov peev txheej hnub ci, huab cua, kev cai hauv tsev hauv zos, thiab teeb meem kev nyab xeeb; Yog li ntawd, nws yog qhov zoo tshaj plaws kom muaj lub hnub ci hluav taws xob tsim hluav taws xob uas tsim nyog rau nruab koj lub cev.
Thaum ntsia, tswj xyuas koj lub cev kom zoo yuav ua kom nws ua haujlwm zoo. Passive systems tsis xav tau kev saib xyuas ntau. Rau cov tshuab ua haujlwm, sib tham txog cov kev xav tau ntawm kev saib xyuas nrog koj tus kws kho mob thiab sab laj nrog koj lub kaw lus tus tswv phau ntawv. Cov kav dej thiab lwm yam khoom siv hluav taws xob hauv dej yuav tsum muaj kev saib xyuas zoo ib yam li cov tshuab pa. Hauv cov huab cua qhuav, dej nag tsis tuaj yeem muab cov dej ntws tawm, yog li kev ntxuav iav yuav tsim nyog.
Cov tshuab yooj yim tuaj yeem xav tau kev saib xyuas tsis tu ncua raws li txhua txhua 3-5 xyoo, nyiam dua los ntawm tus neeg cog lus hnub ci. Cov kab ke nrog cov khoom siv hluav taws xob feem ntau xav tau ib lossis ob ntu hloov tom qab 10 xyoo. Kawm paub ntau ntxiv txog hnub ci dej cua sov qhov system tu thiab kho.

Thaum kuaj xyuas cov kev teeb tsa thiab / lossis kev saib xyuas cov neeg cog lus, nug cov lus nug hauv qab no:
