Q:Kodi pali ubale wotani pakati pa kuthamanga, kutentha ndi kuchuluka kwa nthunzi?
A: Mpweya umagwiritsidwa ntchito kwambiri chifukwa nthunzi ndiyosavuta kugawa, kunyamula ndi kuwongolera. Mpweya ungagwiritsidwe ntchito osati ngati madzi opangira magetsi, komanso kutentha ndi kukonza ntchito.
Pamene nthunzi ikupereka kutentha kwa ndondomekoyi, imakhazikika pa kutentha kosasinthasintha, ndipo mphamvu ya nthunzi yowonongeka idzachepetsedwa ndi 99.9%, yomwe ndi mphamvu yoyendetsa nthunzi mu payipi.
Kuthamanga kwa nthunzi / kutentha ndi chinthu chofunikira kwambiri cha nthunzi. Malinga ndi tebulo la nthunzi, titha kupeza mgwirizano pakati pa kuthamanga kwa nthunzi ndi kutentha. Grafu iyi imatchedwa saturation graph.
Panjira imeneyi, nthunzi ndi madzi zimatha kukhalira limodzi pazovuta zilizonse, ndipo kutentha ndi kutentha kowira. Madzi ndi nthunzi pa kutentha (kapena condensing) kutentha kumatchedwa madzi odzaza ndi nthunzi yodzaza, motero. Ngati nthunzi yodzaza ilibe madzi odzaza, imatchedwa nthunzi yowuma.
Kuthamanga kwa nthunzi / kuchuluka kwa voliyumu ndikofunikira kwambiri pakufalitsa ndi kugawa.
Kuchulukana kwa chinthu ndi kuchuluka komwe kuli mu voliyumu ya unit. Voliyumu yeniyeni ndi voliyumu pa unit mass, yomwe ndi yofanana ndi kachulukidwe. Kuchuluka kwa nthunzi kumatsimikizira kuchuluka kwa nthunzi yomwe imakhala ndi nthunzi yofanana pazovuta zosiyanasiyana.
Kuchuluka kwa nthunzi kumakhudza kusankha kwa chitoliro cha nthunzi, kuchepa kwa boiler ya nthunzi, kugawa kwa nthunzi mu chotenthetsera kutentha, kukula kwa jekeseni wa nthunzi, kugwedezeka ndi phokoso la kutuluka kwa nthunzi.
Pamene kuthamanga kwa nthunzi kumawonjezeka, kuchuluka kwake kumawonjezeka; pomwe, mawu ake enieni adzachepa.
Kuchuluka kwa nthunzi kumatanthauza katundu wa nthunzi ngati mpweya, womwe uli ndi tanthauzo linalake la kuyeza kwa nthunzi, kusankha ndi kuwongolera ma valve olamulira.
