Cartridge heaters yog cylindrical, siab -cov khoom siv ceev ceev feem ntau tsim los rau cov cua sov. Thaum lawv tsis yog tus qauv xaiv rau qhov loj - ntsuas qhov cua sov hauv kev lag luam HVAC (qhov twg finned tubular heaters lossis qhib-coil duct heaters dominate), lawv ua tau zoo hauv kev tshwj xeeb, hauv zos, thiab qhov chaw- txwv tsis pub siv hauv HVAC systems.
Cov ntawv thov tseem ceeb hauv HVAC
- Compressor Crankcase Cua sov: Siv nyob rau hauv scroll, reciprocating, thiab teb compressors. Cov lus qhia tshwj xeeb suav nrog 3/8 "-5/8" txoj kab uas hla, 100-300W, 120/240V. Lawv tiv thaiv cov tub yees tsiv teb tsaws thiab roj dilution.
- Hluav taws xob Enclosure / Vaj Huam Sib Luag Rhaub: Siv rau hauv AHU tswj vaj huam sib luag, VFDs, thiab cov thawv sib txuas. Feem ntau specs yog 1/4 "-1/2" txoj kab uas hla, 50-150W. Lawv muab kev cog lus los tiv thaiv -condensation cua sov.
- VAV / Terminal Unit Reheat: Rau me-zone reheat nyob rau hauv cov chaw kuaj mob, tsev kho mob, lossis chaw ua haujlwm. Specs feem ntau suav nrog 1/2 "-3/4" txoj kab uas hla, 500-1500W. Lawv haum rau qhov chaw nruj nrog kev tswj kom meej.
- Sensor / Probe Cua sov: Rau cov av noo sensors, airflow probes, thiab CO₂ sensors. Hom specs: 1/4 "inch, 25-75W. Lawv tiv thaiv condensation ntawm sensors.
- Damper / Valve Actuator Cua sov: Muaj kev tiv thaiv khov rau dampers thiab li qub. Cov kev qhia tshwj xeeb: 3/8 "inch, 100-200W. Lawv pab tau cov hlau ncaj qha-rau-hlau kov.
- Me Me Inline Cua Heaters: Siv rau hauv cov pa tso pa tawm, cov qauv kab, lossis cov ntaub thaiv cua me me. Specs: 1/2 "inch nrog fins.
Cov txiaj ntsig tseem ceeb hauv HVAC Ib puag ncig
- Compact heev, ua rau lawv zoo tagnrho rau retrofits thiab nruj mechanical qhov chaw.
- watt siab ceev heev (txog 100–150 W/in²), tso cai rau cua sov ceev- nce thiab siab zog hauv pob me me.
- Kev hloov hluav taws xob zoo heev thaum muab tso rau hauv lub bore (split-cov qauv tsim yog nyiam).
- Kev ntseeg siab nyob rau hauv qhov chaw ntub dej / plua plav (thaum epoxy- kaw lossis nrog stainless hlau sheath).
- Kev tswj qhov kub thiab txias thaum ua ke nrog cov ntsuas sov lossis RTDs.
- Lub neej ntev (3,000–8,000+ teev) thaum tsis raug tsim txom.
Pom zoo Specifications rau HVAC Siv
- Sheath Material: 304 lossis 316 stainless hlau rau qhov zoo tshaj plaws corrosion kuj.
- Tsim: Split- sheath (Watt-Flex style) yog qhov nyiam heev- nws nthuav dav rau kev sib cuag zoo dua thiab kev cog lus kom yooj yim tshem tawm.
- Watt Density: 25–60 W/in² for most HVAC applications (avoid >80 W / in² los tiv thaiv kev ua tsis tiav ntxov).
- Termination: Stainless hlau braid los yog armored cable nrog ya raws -cov ntsaws ruaj ruaj.
- Voltage: 120V lossis 240V ib zaug-theem (feem ntau).
- Kev Tiv Thaiv: Cov xaim hauv av, ua tau - hauv qhov ntsuas kub lossis siab - txwv, IP65 / IP67 lead tawm.
- Kev kam rau siab: Precision av txoj kab uas hla (± 0.002") rau nruj bore haum.
Feem ntau yuam kev kom zam
- Siv cov txheej txheem (tsis yog-sib cais) cartridge rhaub hauv aluminium bores, uas ua rau txeeb.
- Cov cua kub qis (watt ceev dhau), ua rau kub hnyiab.
- Kev txhim kho yam tsis muaj thermal paste/compound, ua rau tsis zoo rau cov cua sov hloov mus thiab cov hotspots.
- Siv lawv rau qhov loj - ntim cov kav dej cua sov, vim lawv tsis muaj txiaj ntsig piv rau finned tubular heaters.
Cov kab hauv qab:
Cartridge rhaub tsis yog ib qho kev hloov rau cov kav dej loj hauv feem ntau cov HVAC kev lag luam. Txawm li cas los xij, lawv feem ntau yog qhov zoo tshaj plaws los yog tsuas yog qhov kev xaiv zoo tshaj plaws rau compressor crankcase cua sov, vaj huam sib luag los tiv thaiv -condensation, thiab nruj- qhov chaw reheat daim ntaub ntawv.
Koj puas xav tau cov lus pom zoo rau ib daim ntawv thov tshwj xeeb (xws li, compressor crankcase, VAV reheat, lossis vaj huam sib luag rhaub)?
