Kumvetsetsa Kubwezeretsa Mphamvu mu Rotary Heat Exchangers

Zinthu zazikulu zaukadaulo zomwe zimakhudza kugwiritsa ntchito bwino mphamvu

Kumvetsetsa kubwezeretsa mphamvu mu zosinthira kutentha zozungulira - Zinthu zazikulu zaukadaulo zomwe zimakhudza kugwiritsa ntchito mphamvu moyenera

Machitidwe obwezeretsa kutentha akhoza kugawidwa m'magulu awiri kutengera magawo a kutentha a dongosololi: Machitidwe obwezeretsa mphamvu ndi kusintha kuchokera ku kutentha kotayika komwe kuli ndi magawo ambiri a kutentha (oposa 70).^oC) ndi machitidwe obwezeretsa mphamvu ndikusintha kutentha kuchokera ku zinyalala ndi magawo otsika a kutentha (pansi pa 70^oC).

Makina obwezeretsa kutentha ndi kusintha mphamvu kuposa madigiri 70^oC imagwiritsidwa ntchito mu njira zaukadaulo zomwe zimachitika m'mafakitale amphamvu, chakudya, mankhwala, ndi zina zomwe zimagwiritsa ntchito njira zomwe zimayenderana ndi njira zomwe kutentha kwakukulu kumatulutsidwa. Kutentha kumeneku komwe kumataya mphamvu ndi momwe zinthu zimayendera bwino kungagwiritsidwe ntchito kupititsa patsogolo mphamvu ndi magwiridwe antchito azachuma a mabizinesi mwa kutentha mpweya mwachindunji m'makina opumira mpweya kapena kuwonjezera njira zaukadaulo zomwe zimafuna kutentha kwambiri (monga gwero la kutentha kwa mapampu otenthetsera omwe amagwiritsidwa ntchito popaka mafuta m'makampani opanga chakudya, kapena popanga magetsi mumakina a organic Rankine Cycle kapena Kalina Cycle). Kutentha komwe kumataya mphamvu ndi momwe zinthu zimayendera kutentha kwambiri kungagwiritsidwenso ntchito poziziritsa ndi kuziziritsa mpweya (monga kusintha mphamvu ya kutentha kukhala madzi ozizira pogwiritsa ntchito zoziziritsira zoyamwa kapena zonyowa).

Makina obwezeretsa kutentha ndi kusintha mphamvu pansi pa madigiri 70^oC nthawi zambiri amagwiritsidwa ntchito potenthetsera m'nyumba zogona (monga kutentha pansi pogwiritsa ntchito mapampu otentha) kapena m'nyumba zamalonda (monga m'mayunitsi ogwiritsira ntchito mpweya (AHU) potenthetsera mpweya "watsopano" kapena "wakunja" pobwezeretsa kutentha kuchokera ku mpweya "wogwiritsidwa ntchito" kapena "wotulutsa utsi"). Nkhaniyi ikuyang'ana kwambiri ntchito zomanga nyumba zamalonda.

Machitidwe obwezeretsa kutentha m'mayunitsi oyendetsera mpweya amachokera ku machitidwe awiri omwe, kutengera mtundu wa yankho lomwe lagwiritsidwa ntchito mu kapangidwe ka chipangizocho, amagwiritsa ntchito magetsi (machitidwe ogwirira ntchito) kapena ayi (machitidwe osagwira ntchito). Machitidwe obwezeretsa kutentha m'mayunitsi oyendetsera mpweya akuphatikizapo, mwachitsanzo, machitidwe ozikidwa pa zosinthira kutentha zozungulira kapena mapampu otenthetsera osinthika. Machitidwe obwezeretsa kutentha osagwira ntchito amaphatikizapo zosinthira kutentha zodutsa ndi za hexagonal. Chizindikiro cha kubwezeretsa kutentha m'mayunitsi opumira mpweya ndichakuti kutentha kumabwezeretsedwa pakusintha pang'ono kutentha pakati pa mpweya wotentha kwambiri ndi mpweya wotentha wochepa, pomwe mpweya wotentha kwambiri nthawi zambiri supitirira madigiri 30.^oC (m'nyumba zamalonda, kuchira kwa kutentha kumachitika ngakhale kutentha kwa mpweya kuli kochepa).

Kawirikawiri, kubwezeretsa kutentha m'mayunitsi opumira mpweya ndi oziziritsa mpweya kumachitika pogwiritsa ntchito zosinthira kutentha zozungulira kapena zodutsa (hexagonal), nthawi zambiri pogwiritsa ntchito mapampu otenthetsera. Zosinthira kutentha zozungulira zimagwiritsidwa ntchito mu AHU komwe kusinthana kwakukulu pakati pa mpweya wolowera ndi wotuluka mu AHU kumaloledwa (izi nthawi zambiri zimakhala nyumba za anthu onse). Zosinthira kutentha zodutsa ndi hexagonal zimagwiritsidwa ntchito m'mayunitsi oyendetsera mpweya komwe kusinthana kwakukulu pakati pa mpweya watsopano ndi wogwiritsidwa ntchito sikuloledwa (monga zipatala). Mapampu otenthetsera osinthika amagwiritsidwa ntchito pamene mpweya wopereka kutentha kwambiri ukufunika kuti utenthetse.

Kulinganiza mphamvu ndi kulemera kwa mphamvu mu zosinthira kutentha zomwe zimagwiritsidwa ntchito mu zida zoyendetsera mpweya

Powerengera momwe chosinthira kutentha chozungulira chimagwirira ntchito kuti chibwezeretse kutentha m'mayunitsi ogwiritsira ntchito mpweya, kuwonjezera pa mphamvu yolinganiza, pamafunika mphamvu yolinganiza bwino. Izi ndi ziwerengero za mphamvu ndi kulemera kwabwino kwa kayendedwe kabwino ka steady-state ndi lingaliro lotsatirali. Kusintha kwa nthawi ndi nthawi komwe kumachitika chifukwa cha kayendedwe ka chosinthira kumawerengedwa pamlingo wonse wa mphamvu ndi chinyezi - kutanthauza kuti, kusintha kwa nthawi ndi nthawi kwa kutentha ndi chinyezi pamwamba pa gudumu lozungulira sikuli kofunikira ndipo motero sikuwerengedwa.
