Ni gute wahitamo ibikoresho bipima ubushyuhe mu nganda za HVAC? Sobanukirwa ingingo 4 z'ingenzi mu minota 5
2026-04-21
Guhitamo uburyo butari bwo bwo gupima ubushyuhe bishobora gutuma habaho gupima ubushyuhe nabi, cyangwa bigatuma sisitemu yose y’ubwikorezi bw’inyubako ikora nabi. Ibipimo by'ubushyuhe Mu nganda za HVAC (gukonjesha, gushyushya, guhumeka) ntabwo bigoye cyane - kumenya neza izi ngingo enye z'ingenzi birahagije.
🌡️ Ubwa mbere, menya: Ni ubuhe buryo bwo gupima?
| Hagati | Ubwoko bw'imashini ikoreshwa mu gupima | Ibisabwa by'ingenzi |
|---|---|---|
| Amazi / Ethylene Glycol Umuti | Ubwoko bwo gushyiramo bufite agakoresho gakingira Igipimo cy'ubushyuhe | Ibikoresho by'amaboko: Umuringa cyangwa icyuma kitagira umwanda cya 304 |
| Umwuka (Umuyoboro w'Ihumeka) | Imashini ipima ubushyuhe bw'umuyoboro w'umwuka | Uburebure bw'icyuma gipima ubugari bugomba kugera kuri 1/3 kugeza kuri 1/2 cy'ubugari bw'umuyoboro w'umwuka |
| Ibidukikije byo mu nzu | Imashini ipima ubushyuhe ishyizwe ku rukuta | Isura nziza cyane, irinde ko izuba rigera ku zuba |
| Ibidukikije byo hanze | Ubwoko bw'urukuta rudapfa imvura | Urwego rw'uburinzi ≥ IP65 |
Incamake mu nteruro imwe: Koresha ubwoko bw'icyuma gishyirwamo amazi, ubwoko bw'imiyoboro y'umwuka ikoreshwa mu guhumeka, ubwoko bw'urukuta rukoreshwa mu bidukikije byo mu nzu, n'ubwoko bw'urukuta rudapfa imvura rukoreshwa mu bidukikije byo hanze.
⚡ Amahitamo y'inyongera: Ibintu bipima ubushyuhe n'ibimenyetso bisohoka
Ikintu gikoreshwa cyane mu gupima ubushyuhe mu nganda za HVAC ni Pt100 (platinum thermoresistor), ifite ubuhanga bwo hejuru, ituze ryiza, kandi ifite igipimo cyiza cy'ikiguzi n'imikorere.
Ni gute wahitamo ikimenyetso cy'umusaruro? Reba iyi mbonerahamwe:
| Ikimenyetso cy'ibisohoka | Intera yo kohereza ubutumwa | Ibintu Bishoboka |
|---|---|---|
| Ikimenyetso cyo kurwanya Pt100 (sisitemu y'insinga eshatu) | ≤ metero 50 | Umugenzuzi afite module ye bwite yo gupima ubushyuhe, ifite ubuziranenge bwo hejuru cyane |
| 4-20mA | ≤ metero 500 | Ikunze gukoreshwa cyane, irwanya kubangamira abantu, ikwiriye kohereza ubutumwa kure |
| 0-10V | ≤ metero 100 | Sisitemu zisanzwe mu bwubatsi zikoresha ikoranabuhanga (BAS) |
| RS485 Modbus | ≤ metero 1200 | Ikoreshwa mu nyubako zifite ubwenge, ikwiriye imiyoboro y'amasensa menshi |
Igitekerezo cyo guhitamo:
Huza kuri DDC controller → 0-10V cyangwa 4-20mA
Huza kuri PLC → 4-20mA ni bwo buryo bwizewe cyane.
Ntabwo bizwi neza → 4-20mA, uburyo bworoshye cyane
🔩 Ibisobanuro by'ingenzi: Guteka no gutunganya neza
🛡️ Ku bijyanye n'agatambaro (agatambaro gakingira)
Ku muyoboro w'amazi Ibipimo by'ubushyuhe, ni byiza gukoresha agakoresho ko gukingira. Ibyiza ni ibi bikurikira:
- Rinda sensor kugira ngo idatwarwa n'icyuma gikoresha ikoranabuhanga.
- Sisitemu ishobora gukoreshwa idahagaze kugira ngo isimbuze sensors.
- Ibikoresho: Umuringa usanzwe wo gukoresha mu byuma bikoresha amazi, icyuma kitagira umugese cya Litiro 316 cyo gukoresha mu byuma bikoresha amazi yangiza
🎯 Ku bijyanye n'ubunyangamugayo
Pt100 igabanyijemo Icyiciro A n'Icyiciro B hakurikijwe amahame ngenderwaho y'igihugu:
| Ingano y'Uburinganire | Ikosa kuri 0℃ | Ibintu Bishoboka |
|---|---|---|
| Icyiciro cya A | ± 0.15℃ | Isuku y'ibyumba by'ibitaro, ibigo by'amakuru, igenzura ryimbitse |
| Icyiciro cya B | ± 0.30℃ | Ibiro bisanzwe, amaduka manini, amazu yo guturamo |
Igitekerezo cyo guhitamo: Ku mishinga myinshi ya HVAC, Icyiciro B kirahagije. Ku gupima ubukonje n'ubushyuhe, Icyiciro A ni cyo gisabwa.
📋 Imbonerahamwe y'Ifatizo ryihuse ryo Guhitamo (Kugereranya mu buryo butaziguye)
| Ishusho y'Ikoreshwa | Igice cya Thermometero | Ikimenyetso cy'ibisohoka | Uburyo bwo gushyiraho | Uburyo bwo gukora neza |
|---|---|---|---|---|
| Gutanga amazi akonje n'amazi agaruka | PT100 | 4-20mA | Ubwoko + Ikiziriko | Icyiciro cya B |
| Gushyushya Amazi Ashyushye | PT100 | 4-20mA | Ubwoko bwo gushyiramo + Agapfunyika | Icyiciro cya B |
| Ingufu zo Gutanga/Gusubiza Umwotsi mu Gikonjesha | PT100 | 0-10V | Ubwoko bw'icyumba | Icyiciro cya B |
| Ubushyuhe bwo mu nzu | PT100 | Ubudahangarwa / 0-10V | Ubwoko bw'urukuta | Icyiciro cya B |
| Ubushyuhe bwo hanze | PT100 | 4-20mA | Ubwoko bw'imvura bushyirwa ku rukuta | Icyiciro cya B |
💡 Ibuka izi nteruro 3 mbere yo kugura
- 1 Kumenya uko ishyirwamo rishingiye ku buryo buciriritse: Ubwoko bw'aho amazi ashyirwa, ubwoko bw'icyumba cy'umwuka.
- 2 Ikimenyetso cyo gushyiraho intera: Koresha uburinzi mu ntera ngufi, na 4-20mA mu ntera ndende.
- 3 Umuyoboro ufite agakoresho ko kurinda: Bizigama amafaranga kandi biroroshye, bifasha kubungabunga bidahagaritse imikorere.
🏢 Ku bijyanye natwe
Weilian Electronic Technology yibanda ku bikoresho by'ubushyuhe bikoreshwa mu mikorere ya HVAC n'inganda. Ibicuruzwa byacu bikubiyemo ibi bikurikira:
- Umuyoboro w'amazi / umuyoboro w'umwuka / sensor y'ubushyuhe mu nzu no hanze
- Pt100 / 4-20mA / 0-10V / RS485 umusaruro
- Shyigikira uburebure bw'insinga n'ingano y'icyuma gipima
