Zabar dama na bawul din lantarki da ya dace don tsarin hvac

Zabi wani bawul din lantarki da ya dace yana da mahimmancin inganta ingancin tsarin Hvac, dogaro, da sarrafawa. Anan akwai mahimman dalilai don la'akari:

1. Girma da ƙarfin kwarara

Yi dace da girman bawul zuwa diamita na hvac (misali, ½ "zuwa 4") don guje wa ƙuntatawa na gudummawa ko matsi mai yawa. Lissafa ingantaccen kwararar da ake buƙata (CV) dangane da ƙimar kwarara da keɓaɓɓe da bambancin da ba a taɓa samun daidaito ba, yayin da ake kunnawa uwayen iko.

2. Karancin abu

Abubuwan da ke cikin bawul da kayan ciki dole ne su yi tsayayya da lalata daga hvac ruwaye (ruwa, glycol gaurayo, ko sanyaya). Don tsarin tushen ruwa, tagulla ko baƙin ƙarfe yana da inganci da kuma m. Domin coolan coolasative, ficewa bakin karfe . Seals ya kamata ya yi amfani da EPDM ko biton don tabbatar da rufe-kashe da kuma dacewa tare da kayan ruwa.

3. Nau'in mai aiki da sarrafawa

Zabi tsakanin / Kashe Ayyuka na Bude Mai Sauya / Rufe Ayyuka (EG, Keyulting Actulates don daidaitawa da daidaitawa (misali, tsarin zafin jiki). Modulating bawuloli, tare da 0-10v ikon sarrafa siginar iko, bayar da sigina don sake kunna iska ko tsarin kwarara. Tabbatar da ƙimar Torque na Apporator ya dace da girman bawul don gujewa Jamming.

4. Matsala da zazzabi da zazzabi

Duba matsakaiciyar matsakaicin matsakaiciyar bawul na Valve (yawanci 15000 PSI) da kewayon zazzabi (-3000 f zuwa 70 ° F saboda yawancin aikace-aikacen Hvac) don dacewa da yanayin tsarin. Tsarin high-zazzabi (misali, hydronic dumama) na iya buƙatar awzuka tare da hatimin zafi-mai tsayayya da jiki.

5. Amincewa da shigarwa

Fifikon babi na lantarki tare da m evilators extaretors (IP65 / IP67 na IP67 don juriya danshi) don tsayayya maharan hvac. Nemi fasali kamar fasali na override na gaggawa da kuma madaidaiciyar hanyar (an yi masa haske ko zaren haɗi) don sauƙaƙa shigarwa da tabbatarwa.

Ta hanyar mai da hankali kan girman, kayan, nau'in sarrafawa, da ƙididdigar aiki, zaku iya zaɓar farashin tsarin Hvac kuma yana rage farashin ajiyar Hvac.
