——Iyo air conditioner tembiricha sensor is negative tembiricha coefficient thermistor, inonzi NTC, inozivikanwawo setembiricha probe. Kukosha kwekudzivirira kunoderera nekuwedzera kwekushisa, uye kunowedzera nekuderera kwekushisa. Iko kukosha kwekupikisa kwe sensor kwakasiyana, uye kukosha kwekupikisa pa 25 ℃ ndiko kukosha kwezita.
Plastic-encapsulated sensorsanowanzo dema, uye anonyanya kushandiswa kuona ambient tembiricha, nepometal-encapsulated sensorsanowanzo simbi isina tsvina sirivha uye simbi mhangura, ayo anonyanya kushandiswa kuona pombi tembiricha.
Iyo sensor inowanzova miviri mitema inotungamira padivi padivi, uye resistor yakabatana kune socket ye control board kuburikidza neinotungamira plug. Pane kazhinji masensa maviri mukamuri yekufemesa. Mamwe maairconditioner ane maviri akaparadzana-waya plugs, uye mamwe air conditioners anoshandisa imwe plug uye mana anotungamira. Kuitira kusiyanisa ma sensors maviri, ma sensor akawanda emhepo, mapulagi uye zvigadziko zvinogadzirwa kuti zvizivikanwe.
——Masensa anowanzo shandiswa muma air conditioners ndeaya:
Indoor chubhu tembiricha NTC
Kunze pombi tembiricha NTC, nezvimwewo.
Ma air conditioners epamusoro anoshandisawo kunze ambient tembiricha NTC, compressor suction uye exhaust NTC, uye ma air conditioners ane indoor unit inofuridza mhepo tembiricha NTC.
——Basa rakajairika remasensa ekupisa
1. Indoor ambient tembiricha yekuona NTC (negative tembiricha coefficient thermistor)
Zvinoenderana neseti yekushanda mamiriro, iyo CPU inoona tembiricha yenzvimbo yemukati kuburikidza nemukati ambient tembiricha (inonzi tembiricha yemukati mhete) NTC, uye inodzora compressor kuti ibatiswe kana kudzima kuti imire.
Iyo inochinja frequency air conditioner inoita inochinja frequency yekumhanyisa regulation zvinoenderana nemusiyano pakati peseti yekushanda tembiricha uye tembiricha yemukati. Paunenge uchimhanya pamhepo yakakwira mushure mekutanga, iyo yakakura mutsauko, inokwira iyo compressor inoshanda frequency.
2. Indoor tube tembiricha yekuona NTC
(1) Mumamiriro ekutonhora, tembiricha yemukati chubhu NTC inoona kana tembiricha yecoil yemukati inotonhora zvakanyanya, uye kana tembiricha yecoil yemukati inodonha kune imwe tembiricha mukati menguva yakati.
Kana kuchinyanya kutonhora, kuitira kudzivirira iyo indoor unit coil kubva kuchando uye kukanganisa kuchinjana kwekupisa kwemukati, iyo CPU compressor ichavharwa kuti dzidzivirire, iyo inonzi supercooling dziviriro.
Kana tembiricha yemukati coil ikasadonha kune imwe tembiricha mukati meimwe nguva yenguva, iyo CPU ichaona uye kutonga dambudziko refiriji system kana kushomeka kwefiriji, uye compressor ichavharwa kuti idzivirire.
(2) Anti-kutonhora kuvhuvhuta mhepo kuvhuvhuta, overheating unloading, overheating dziviriro, kudziyisa mhedzisiro kuona, etc. mukupisa mamiriro. Kana iyo air conditioner inotanga kupisa, kushanda kwemukati fan kunodzorwa nekupisa kwemukati chubhu. Kana tembiricha yechubhu yemukati yasvika 28 kusvika 32 °C, feni inomhanya kudzivirira kudziyisa kutanga kuburitsa mweya unotonhora, zvichikonzera kusagadzikana mumuviri.
Munguva yekupisa, kana tembiricha yepombi yemukati inosvika 56 ° C, zvinoreva kuti tembiricha yepombi yakanyanyisa uye kudzvanywa kwakanyanya. Panguva ino, iyo CPU inodzora feni yekunze kuti imire kuderedza kunyura kwekupisa kwekunze, uye compressor haimire, iyo inonzi kupisa kuburitsa.
Kana tembiricha yechubhu yemukati ichiramba ichikwira mushure mekunge fan yekunze yamira, uye yasvika 60 ° C, iyo CPU ichadzora iyo compressor kumisa kudzivirira, inova inodzivirira kupisa kwemhepo inofefetera.
Mumamiriro ekudziya kweair conditioner, mukati meimwe nguva yenguva, kana tembiricha yechubhu yeimba yemukati ikasakwira kune imwe tembiricha, iyo CPU ichaona dambudziko refiriji system kana kushomeka kwefiriji, uye compressor ichavharwa kuti idzivirire.
Izvo zvinogona kuoneka kubva pane izvi kuti kana iyo air conditioner ichidziya, zvese zviri mukati memukati fan uye yekunze fan inodzorwa neyemukati pombi tembiricha sensor. Naizvozvo, kana uchigadzirisa kutadza kwekushanda kwe fan ine chekuita nekudziya, teerera kune yemukati pombi tembiricha sensor.
3. Kunze kwepombi kuona tembiricha NTC
Basa guru rekunze chubhu tembiricha sensor kuona kudziyisa uye defrosting tembiricha. Kazhinji, mushure mekunge air conditioner yapisa kwemaminetsi makumi mashanu, chikamu chekunze chinopinda mukutanga kunyungudutswa, uye chinotevera defrosting chinodzorwa nekunze kwechubhu tembiricha sensor, uye tembiricha yechubhu inodonha kusvika -9 ℃, inotanga kunyunguduka, uye kumira kunyungudika kana. tembiricha yechubhu inokwira kusvika 11-13 ℃.
4. Compressor exhaust gasi kuona NTC
Dzivisa kupisa kwecompressor, kuona kushomeka kwefluorine, kuderedza kuwanda kweiyo inverter compressor, kudzora kuyerera kwefiriji, nezvimwe.
Pane zvikonzero zviviri zvakakosha zvekushisa kwakanyanya kwekubuda kwe compressor. Imwe ndeyokuti compressor iri mune yakawandisa yekushanda mamiriro, kunyanya nekuda kwekushayikwa kwekupisa kupisa, kukwira kwepamusoro uye kudzvanywa kwepamusoro, uye imwe yacho kushaikwa kwefiriji kana kusave nefiriji mufiriji system. Kupisa kwemagetsi uye kupisa kunopisa kwe compressor pachayo haigoni kubudiswa zvakanaka nefiriji.
5. Compressor kusveta kuona NTC
Mufiriji system yeair conditioner ine electromagnetic throttle valve, CPU inodzora kuyerera kwefiriji nekuona tembiricha yemhepo inodzoka yecompressor, uye stepper mota inodzora throttle valve.
Iyo compressor suction tembiricha sensor inoitawo basa rekuona kutonhora kwekuita. Pane firiji yakawandisa, tembiricha yekukweva yakadzikira, firiji ishoma kana kuti firiji system yakavharika, tembiricha yekukweva yakakwira, tembiricha yekusveta isina firiji iri padyo neambient tembiricha, uye CPU Ona tembiricha yekusveta ye. iyo compressor kuona kana air conditioner iri kushanda zvakajairika.
