Ithangi Lokugcina Lamanzi Abandayo Anengcindezi Ngokumelene Nethangi Lomoya: Yiluphi Okufanele Lucaciswe
Ithangi lokugcina lamanzi abandayo anengcindezi lingaphakathi kwe-loop ye-hydronic evaliwe lapho amanzi agciniwe kufanele ahlale ngaphezu kwengcindezi yawo yomhwamuko. Ithangi lomoya lishibhile ngobukhulu obukhulu futhi limunca ukunwetshwa ngokusebenzisa indawo yalo ekhululekile, kodwa liphoqa ukuhlukana kwengcindezi okukhokhwa amaphampu. Cacisa lelo umngcele wengcindezi kanye nesidingo somthamo okufunayo.
Isingeniso
Ukukhetha phakathi kwethangi lamanzi abandayo acindezelwe kanye nethangi lamanzi abandayo asemoyeni akusona isihloko sokumboza noma sezinto ezisetshenziswayo; kuyisinqumo mayelana nokuthi umngcele wengcindezi yesistimu ukhona kuphi, futhi leso sinqumo sithinta ukukhethwa kwepompo, ukusetshenziswa kwamandla kanye nokulawulwa kokwanda. Uma ucacisa isitoreji samandla ashisayo semboni yamanzi abandayo, ukhetha phakathi kokugcina amanzi agciniwe ngaphakathi komjikelezo ocindezelwe noma ukuwavumela ukuthi ahlale engcindezini yomoya ngemuva kwesishintshi sokushisa noma ukuphuka kwengcindezi.
Le ndatshana ibeka ukushintshana ngokwemibandela yobunjiniyela hhayi njengokuthanda umkhiqizo. Ihlanganisa ukuthi yini ehlukanisa ngokomzimba lezi zinhlobo ezimbili zemikhumbi, ukuthi ingcindezi yokusebenza ishintsha kanjani ikhanda lepompo kanye nesimo samandla, ukuthi ukuhlelwa ngakunye kubhekana kanjani nokwanda kokushisa, nokuthi isigxivizo se-ASME BPVC Section VIII singena kuphi. Ukukhethwa kuyisibalo, hhayi isiqubulo, futhi kuphetha ngohlaka ongalusebenzisa kudatha yakho.
Izinkomba ezilawulayo yi-ASME BPVC Section VIII yomkhumbi wengcindezi, i-ASME B31.9 yamapayipi ezinsizakalo zebhilidi, kanye ne-ASHRAE Handbook yesisekelo somthwalo. Izinga lisho imfuneko; aliqinisekisi ithangi, ngakho-ke cacisa isitembu esifunwa ukubalwa.
Yini ehlukanisa umkhumbi ocindezelwe nomkhumbi womoya
Isitsha sokugcina amanzi abandayo acindezelwe sakhiwe njengomngcele wengcindezi: siqukethe amanzi agciniwe engcindezini yokulinganisa engaphezu komkhathi, ehambisana nengcindezi yokusebenza yomjikelezo, ukuze indawo ekhululekile icindezelwe futhi amanzi ahlale ewuketshezi ezindaweni ezinengcindezi ephansi kakhulu yomjikelezo. Iqokobhe laso, iziphimbo, izindlela zokungena kanye nendlela yokukhulula ziklanyelwe futhi zihlolwa kuleyo ngcindezi. Ithangi lomkhathi, ngokuphambene, likhishwa emkhathini; amanzi agciniwe ahlala ku-0 psig (0 kPa(g)) noma eduze kwayo futhi aphefumula ngomoya noma ngophahla olugobile, kanti iqokobhe lakho liklanyelwe kuphela ukuthwala umthamo wamanzi kanye nemithwalo yomoya noma yokuzamazama komhlaba, hhayi ukugcina ingcindezi.
Umugqa wokwehlukanisa ongokoqobo ukugqashuka kwengcindezi. Ohlelweni lomoya ithangi ngokuvamile lixhunywe ku-loop ecindezelwe ngesishintshi sokushisa, noma i-loop iwela lapho kugqashuka khona lapho isethi ehlukile yokucindezela igcina ingcindezi ye-loop kuyilapho ithangi lihlala emoyeni.
