Kodi kukula kwa switch kwa AC mini split system ndi chiyani? (Njira 3 zowerengera)
Zamkatimu
Ngati mulibe kusankha yoyenera dera wosweka wanu mini kugawanika, inu mukhoza kukumana ndi mavuto angapo. Kuchita izi kukhoza kusokoneza chophwanya kapena kuwononga mini AC unit. Kapena mungakhale ndi vuto lalikulu kwambiri, monga moto wamagetsi. Chifukwa chake, kuti mupewe zonsezi, lero ndikuthandizani kuti muwone chomwe chimaphwanya kukula bwino kwa makina anu owongolera mpweya. Kaya mukugwiritsa ntchito kanyumba kakang'ono ka 2 ton mini split air conditioner kapena lalikulu 5 ton one, nkhaniyi ikuthandizani kwambiri.
Nthawi zambiri, pa 24000 BTU/2 tani mini split unit, mudzafunika 25 amp circuit breaker. Pa 36000 BTU/3 tani mini split unit, mudzafunika 30 amp circuit breaker. Ndipo pagawo lalikulu la 60000 5 BTU/50 ton split, mudzafunika XNUMX amp circuit breaker.
Werengani nkhaniyi pansipa kuti mumve zambiri.
Kodi ndimadziwa bwanji kukula kwa switch ya AC mini split unit yanga?
Magawo ang'onoang'ono ogawanika ndi abwino kwa chipinda chaching'ono kapena malo chifukwa chosavuta kugwiritsa ntchito ndikuyika popanda kusintha kwakukulu kwa mpweya wapakati ndi nyumba; zipangizozi ndi otchuka pakati pa mabanja ambiri American. Funso lodziwika bwino ndilakuti ndi switch iti yomwe ili yoyenera pagawo laling'ono la AC?
Siziyenera kukhala zovuta. Pali njira zitatu zopezera chowotcha chozungulira chadongosolo lanu latsopano la mini AC.
- Mutha kugwiritsa ntchito MAX FUSE ndi MIN Circuit Ampacity values kuti mudziwe kukula kwa switch.
- Mutha kugwiritsa ntchito mphamvu yayikulu ya chipangizocho ndikuwerengera kukula kwa chosinthira.
- Kapena gwiritsani ntchito mitengo ya BTU ndi EER kuti muwerengere kukula kwake.
Njira 1 - MAX. FUSE ndi MIN. dera panopa
Njirayi imathandiza kudziwa kukula kwa breaker pamene MAX FUSE ndi MIN Circuit Ampacity akhazikitsidwa. Miyezo iyi nthawi zambiri imasindikizidwa pa dzina la mini split air conditioner. Kapena onani buku la malangizo.
Musanafotokoze bwino njira yoyamba, muyenera kumvetsetsa bwino MAX. FUSE ndi MIN. dera panopa. Kotero apa pali kufotokoza kosavuta.
MAXIMUM FUSE
Mtengo wa fuse wa MAX ndiye kuchuluka kwapano komwe gawo logawika la AC limatha kugwira, ndipo simuyenera kuwonetsa gawo la AC mini split kupitilira mtengo wa MAX FUSE. Mwachitsanzo, ngati gawo lanu la AC lili ndi mlingo wa MAX FUSE wa 30 amps, silingathe kupitirira apo. Chifukwa chake, wopatsira dera wodzipereka omwe mumagwiritsa ntchito sayenera kupitilira 30 amps.
Komabe, uwu ndiye mtengo wokwera kwambiri ndipo simungathe kukula kosinthira motengera momwemo. Mudzafunikanso mtengo wotsatira pa izi.
MIN. mphamvu yozungulira
Mutha kugwiritsa ntchito mtengo wa MIN Circuit Ampacity kuti mudziwe kuchuluka kwa waya ndi kukula kwake kocheperako kwa gawo laling'ono la AC.
Mwachitsanzo, ngati mukugwiritsa ntchito chipangizo cha AC chokhala ndi ma amps 20, muyenera kugwiritsa ntchito waya wa 12 AWG kulumikiza dera. Ndipo simungagwiritse ntchito chodulira chigawo pansi pa 20 amps pagawo la AC.
Ubale MAX. FUSE ndi MIN. dera panopa
Malinga ndi kuchuluka kwa MINIMUM kwa dera, MAX. FUSE nthawi zambiri imaposa kukula kwa chimodzi kapena ziwiri. Mwachitsanzo, ngati MIN. chigawo chapano ndi 20 amps, MAX mtengo. FUSE iyenera kukhala 25 kapena 30 amps.
Chifukwa chake ngati tilingalira magawo otsatirawa a mini AC:
25 kapena 30 amp circuit breaker ingagwiritsidwe ntchito pa chipangizochi. Komabe, kutengera kukula kwa chosinthira, muyenera kusinthanso waya.
| Circuit breaker mtengo wapano | Kuchepa kwa waya (AWG) |
| 15 | 14 |
| 20 | 12 |
| 30 | 10 |
| 40 | 8 |
| 55 | 6 |
| 70 | 4 |
Malinga ndi tebulo pamwambapa, gwiritsani ntchito waya 12 kapena 10 AWG pa 25 amp circuit breaker. Ndipo pa 30 amp breaker, gwiritsani ntchito AWG 10 American Wire Gauge yokha.
Indoor ndi kunja mini split air conditioning unit
Ngati mumadziwa mini split AC unit, mwina mukudziwa kuti ma AC mayunitsiwa amapangidwa ndi magawo awiri osiyana.
- Compressor panja
- Chipinda chothandizira mpweya m'nyumba
Zingwe zinayi zimagwirizanitsa magawo awiriwa. Zingwe ziwiri zimaperekedwa kwa refrigerant. Chingwe chimodzi ndi choperekera magetsi. Ndipo chomalizacho chimagwira ntchito ngati chubu.
Nanga bwanji ngati zigawo zonse zili ndi MAX FUSE ndi MIN mayendedwe apano?
Mwachidziwikire, MAX FUSE ndi MIN Circuit Ampacity values amasindikizidwa pamiyala yamayunitsi amkati ndi akunja. Ndipo anthu ambiri amasokonezeka pazomwe angasankhe posintha masinthidwe. Kunena zowona, chisokonezo ichi ndi chomveka.
Chigawo chakunja (compressor) chiyenera kusankhidwa nthawi zonse pamene chimapereka mphamvu ku gawo loyendetsa mpweya.
Njira 2 - mphamvu yaikulu
Njira yachiwiriyi ikufuna kukula kwa wowononga dera pogwiritsa ntchito mphamvu zambiri. Kuti muchite izi, tsatirani izi.
Gawo 1 - Pezani mphamvu zambiri
Choyamba, pezani mphamvu yayikulu kwambiri. Iyenera kusindikizidwa pa mbale yoyezera. Kapena mungachipeze m’buku la malangizo. Ngati simukuchipeza, fufuzani pa intaneti buku logwirizana ndi chipangizo chanu.
Gawo 2 - Pezani zamakono
Kenako gwiritsani ntchito lamulo la Joule kuti mupeze zomwe zilipo.
Malinga ndi lamulo la Joule,
- P - mphamvu
- Ndine pano
- V - mphamvu
Choncho,
Tengani P monga 3600W ndi V monga 240V chitsanzo ichi.
Kagawo kakang'ono ka AC kamakoka zosaposa 15A.
Khwerero 3: Gwiritsani ntchito NEC 80% Rule
Pambuyo powerengera kuchuluka kwa AC unit panopa, gwiritsani ntchito lamulo la NEC 80% pachitetezo chachitetezo cha dera.
Choncho,
Izi zikutanthauza kuti 20 amp breaker ndiye njira yabwino kwambiri pagawo lomwe tatchulalo la 3600W mini AC. Gwiritsani ntchito waya wa 12 AWG pamagawo amagetsi.
Njira 3 - BTU ndi EER
Ngati mumadziwa mayunitsi otenthetsera mpweya, mwina mumawadziwa bwino mawu akuti BTU ndi EER. Mawu awa ndi British Thermal Unit ndi Energy Efficiency Ratio.
Komanso, mutha kupeza izi mosavuta patsamba laling'ono la mini split unit kapena buku. Ndipo zikhalidwe ziwirizi ndizokwanira kuwerengera kuchuluka kwa gawo laling'ono la gawo lanu la mini AC. Umu ndi momwe mungachitire.
Khwerero 1. Pezani zoyenera za BTU ndi EER.
Choyamba, lembani mfundo za BTU ndi EER pagawo lanu laling'ono la AC.
Landirani zomwe zili pamwambapa zachiwonetserochi.
Khwerero 2 - Kuwerengera mphamvu yayikulu
Gwiritsani ntchito ndondomekoyi kuti muwerenge mphamvu zambiri.
Khwerero 3 - Mawerengeredwe apano
Mutatha kuwerengera mphamvu yaikulu, gwiritsani ntchito mtengo uwu kuti mudziwe mphamvu zomwe zilipo.
Malinga ndi lamulo la Joule,
- P - mphamvu
- Ndine pano
- V - mphamvu
Choncho,
Tengani P monga 6000W ndi V monga 240V chitsanzo ichi.
Kagawo kakang'ono ka AC kamakoka zosaposa 25A.
Khwerero 4: Gwiritsani ntchito NEC 80% Rule
Choncho,
Izi zikutanthauza kuti 30 amp breaker ndiye njira yabwino kwambiri ya 36000 BTU mini AC unit yomwe tatchulayi. Gwiritsani ntchito waya wa 10 AWG pamagawo amagetsi.
zofunika: Zotsatira pamwambapa zitha kusiyana kutengera mtengo wa EER, voliyumu ndi mtengo wa BTU wa mini AC unit yanu. Choncho, onetsetsani kuti kuwerengera kwatsirizidwa moyenera.
Kodi njira yabwino kwambiri yopangira ma circuit breaker ndi iti?
Zowonadi, njira zonse zitatuzi ndizabwino pakuzindikira kukula koyenera kwa gawo lanu laling'ono la AC. Koma muyenera kusamala pang'ono pochita gawo lowerengera. Njira imodzi yolakwika ingabweretse tsoka. Izi zitha kuwotcha chigawo cha AC unit. Kapena moto wamagetsi ungayambike.
Ndipo ngati mungagwiritse ntchito njira ziwiri pa chipangizo chomwecho, zidzakhala zotetezeka. Komanso, ngati mukuona kuti simukumasuka kugwira ntchito zoterezi, onetsetsani kuti mwapempha thandizo kwa katswiri wodziwa bwino ntchitoyo.
