Ifanele ifakwe phi iValve yokulinganisela

Iivalvu zokulinganiselazizinto ezibalulekileyo kwiinkqubo ze-HVAC kunye ne-hydronic, ezisetyenziselwa ukulawula nokuhamba kolwelo ukuze kufezekiswe ukusebenza okusebenzayo, okuhlala kuhleli, nokuthembekileyo. Kodwa abayili beenkqubo abaninzi kunye namaqela okulungisa badla ngokubuza oku:apho kufuneka ifakwe khona ivalvu yokulinganiselaukuqinisekisa ukusebenza okuphezulu?

Masingene nzulu kwimpendulo, sijonge iindlela zokwenza ishishini, ingqiqo, kunye namaqhinga okubeka izinto, ngelixa silungiselela amagama aphambili okukhangela afana nokufakelwa kweevalvu zokulinganisela, indawo yeevalvu zokulinganisela ze-HVAC, kunye noyilo lwenkqubo ye-hydronic.

Yintoni iValve yokulinganisela

Ivalvu yokulinganisela sisixhobo esisetyenziselwa ukulawula ukuhamba kolwelo kwiinkqubo zokufudumeza nokupholisa. Inceda ukugcina amazinga okuhamba afanelekileyo, iqinisekisa ukuba zonke iindawo zesakhiwo zifumana amandla obushushu afanelekileyo, nokuba ngamanzi ashushu okanye abandayo. Ezi valve zibalulekile ekuphepheni iingxaki ezifana nokufudumeza ngaphantsi kobushushu, ubushushu obugqithisileyo, okanye ukusetyenziswa kwamandla okungasebenzi kakuhle.

Kukho iintlobo ezimbini eziphambili:

• ①Iivalufa zokulinganisela ngesandla(isetyenziselwa iinkqubo ezingashukumiyo)

• ②Iivalufa zokulinganisela ezizenzekelayo(ilungele iinkqubo ezitshintshayo)

Ngoko ke, kufuneka iValve yokulinganisela ifakwe phi

1. Kwicala lokuBuyela leYunithi yesiphelo (Indawo ekhethwayo)

Kwiinkqubo ezininzi ze-HVAC zanamhlanje—ingakumbi ezo ziquka iiyunithi ze-fan coil (ii-FCU), iiyunithi zokuphatha umoya (ii-AHU), okanye imiqadi ebandayo—ivalvu yokulinganisela ifakwe kumgca wokubuyela, ngezantsi kwe-coil okanye iyunithi yesiphelo.

Ngoba?

• ①Umlinganiselo ochanekileyo wokuhamba kwamanzi: Umgca wokubuya ubonelela ngomfanekiso ongcono wokuhamba kwamanzi okupheleleyo kwiyunithi.

• ②Ukususwa koMoya: Kunciphisa umngcipheko wokubanjwa komoya kwinkqubo kuba umoya uhlala uqokelelana kwimigca yokuhambisa, kwaye awufuni ukuba ubambeke kufutshane nendawo yokulinganisa.

• ③Inzuzo yokuHlamba: Ukufakela kumgca wokubuyisela kuvumela ukuba inkqubo ihlambe ngokulula ukusuka kumthombo ukuya kwicala lokubuyisela.

2. Ekupheleni kweSebe eliPhambili ngalinye okanye iSekethe eNcinci

Kwiinkqubo ze-hydronic ezintsonkothileyo ezineeluphu ezininzi okanye iindawo, njengakwizakhiwo ezinemigangatho emininzi okanye iinkqubo ezinkulu zorhwebo, iivalvu zokulinganisela zifakelwa ekupheleni kwesekethe nganye ukuqinisekisa:

• ①Usasazo olulinganayo loxinzelelo

• ②Ukuhamba ngokulinganayo kwesebe ngalinye

• ③Ibhalansi ebanzi yenkqubo

Olu qwalaselo lufanelekile kwiinkqubo zemibhobho ezijikelezayo (umz., iinkqubo zokubuyisela umva okanye zokubuyisela ngqo).

3. Iivalvu zoLawulo zangaphambi okanye emva (Kuxhomekeke kuYilo)

Kwiinkqubo ezineevalvu zokulawula ezizimeleyo ngoxinzelelo (ii-PICV), ukulinganisela kunokuphathwa ngaphakathi, kwaye iivalvu zokulinganisela ezongezelelweyo zisenokungafuneki kwinqanaba leyunithi yesiphelo. Kodwa kwiinkqubo ezineevalvu zokulawula ezimacala mabini kwaye zingenazo ii-PICV, ivalvu yokulinganisela kufuneka ibekwe emva kwekhoyili kunye nevalvu yokulawula, kumgca wokubuya.

4. Iintloko zePump Discharge (Zokulinganisela Inkqubo)

Kwiinkqubo zeprayimari okanye zesekondari okanye iinkqubo zokuhamba kweprayimari eziguquguqukayo, iivalvu zokulinganisela nazo zingasetyenziswa:

• ①Kwiiheader zokukhupha ipompo

• ②Kwimigca yokudlula okanye kwiindawo zokuqhawula

Oku kunceda ukulawula uxinzelelo olwahlukileyo kunye nokuzinzisa ukusebenza kwenkqubo.

Iingcebiso zokufaka

• ①Sebenzisa iivalvu zokulinganisela ezineendawo zokulinganisa ukuhamba kwamanzi ukuze uvumele ukusebenza ngokukhawuleza.

• ②Beka iivalvu kwiindawo ezifikelelekayo ukuze uhlengahlengiso nolondolozo luqhubeke.

• ③Cinga ngemilinganiselo yobushushu kunye noxinzelelo efanelekileyo kwiinkcukacha zenkqubo yakho.

• ④Linganisa inkqubo usebenzisa izixhobo ezikhethekileyo okanye iimitha zokuhamba kwedijithali ukuze ufumane ukuchaneka.

• ⑤Dibanisa nabalawuli boxinzelelo obahlukeneyo okanye ii-PICV kwiinkqubo zokuhamba kwamanzi eziguqukayo.
