Menene thermostat?

Thermostat yana nufin jerin abubuwan sarrafawa ta atomatik waɗanda ke lalacewa ta jiki a cikin canji bisa ga canje-canjen zafin jiki a yanayin aiki, ta haka yana haifar da wasu tasiri na musamman da samar da gudanarwa ko ayyukan cire haɗin gwiwa. Ana kuma kiransa maɓalli mai sarrafa zafin jiki, mai kariyar zafin jiki, mai sarrafa zafin jiki, ko ma'aunin zafi da sanyio a takaice. Ana iya amfani da ma'aunin zafi da sanyio don sarrafawa da daidaita yanayin zafi. Lokacin da zafin jiki ya kai ƙimar da aka saita, ana kunna ko kashe wutar ta atomatik don cimma burin dumama ko sanyaya.

 

 

Ka'idar aiki na thermostat

yawanci don yin samfuri da lura da zafin yanayi ta hanyar firikwensin zafin jiki. Lokacin da yanayin yanayi ya fi girma ko ƙasa da ƙimar sarrafa saiti, da'irar sarrafawa za ta fara da fitar da siginar sarrafawa daidai don cimma daidaiton yanayin zafi da sarrafawa. Wasu ma'aunin zafi da sanyio kuma suna da aikin ƙararrawa mai iyaka. Lokacin da zafin jiki ya zarce ƙimar ƙararrawa saita, za a fitar da sautin ƙararrawa ko siginar haske don tunatar da mai amfani don sarrafa shi cikin lokaci.

Thermostats suna da nau'ikan aikace-aikace da yawa kuma ana iya amfani da su a cikin kayan aiki daban-daban waɗanda ke buƙatar dumama ko sanyaya, kamar tanda na lantarki, firiji, na'urorin sanyaya iska, da sauransu. A lokaci guda kuma ana iya amfani da ma'aunin zafi da sanyio a fannonin masana'antu daban-daban, kamar masana'antar sinadarai, magunguna, sarrafa abinci, da sauransu, don cimma daidaiton kula da zafin jiki yayin aikin samarwa.

A lokaci guda, yayin amfani, kuna buƙatar kula da kulawa da gyarawa, kuma a kai a kai bincika daidaito da ji na firikwensin don tabbatar da aiki na yau da kullun na thermostat.

 

Rarraba Thermostat

Ana iya rarraba thermostat bisa ga ayyukansu, musamman gami da nau'ikan masu zuwa:

 

 

Injiniyan thermostat

Ma'aunin zafin jiki na injina yana amfani da tsarin inji don aunawa da daidaita yanayin zafi. Yawancin lokaci ana amfani dashi a cikin kayan aikin gida na tattalin arziki da sauƙi kamar dumama, kwandishan da kwandishan. Hakanan za'a iya amfani dashi tare da wasu tsarin don samar da hadaddun tsarin sarrafa atomatik. Amfaninsa shine ƙananan farashi da sauƙin amfani. Rashin hasaransa shine ƙarancin daidaito, iyakanceccen kewayon daidaitawa da aiki maras dacewa.

 

 

Wutar lantarki

Wutar lantarki ta lantarki tana amfani da kayan lantarki don auna zafin jiki da sarrafa daidaitawa. Yana da halaye na babban madaidaici, hankali, ayyuka masu ƙarfi, da sauƙin aiki. An fi amfani dashi a cikin manyan masana'antu, kasuwanci da kayan aikin gida. Hanyoyin daidaitawa na gama gari sun haɗa da PID algorithm, ƙirar bugun bugun jini PWM, daidaita madaidaicin madaidaicin sifili ZPH da iko mara nauyi, da sauransu, wanda zai iya cimma daidaitaccen sarrafa zafin jiki da ceton kuzari da tasirin rage amfani. Ma'aunin zafi da sanyio na dijital da PID mai kula da zafin jiki ana samun aiki bisa tushen ma'aunin zafi da sanyio na lantarki.

 

 

Dijital thermostat

Ma'aunin zafi da sanyio na dijital na'urar sarrafa zafin jiki ce wacce ke haɗa nunin dijital da mai sarrafa dijital, wanda zai iya nuna ƙimar zafin jiki na yanzu da saita ƙimar zafin jiki, kuma ana iya saita shi da hannu ta hanyar maɓalli da sauran hanyoyin. Yana da babban madaidaici, ingantaccen aminci da aiki mai sauƙi. Wurin da'irar da aka gina ta yayi kama da ma'aunin zafi da sanyio. Ya dace da lokutan da ake buƙatar daidaita yanayin zafi akai-akai, kamar dakunan gwaje-gwaje, kayan lantarki, da sauransu.

PID mai sarrafa zafin jiki

 

A cikin sarrafa tsari, mai sarrafa PID (wanda kuma ake kira PID regulator) wanda ke sarrafawa bisa ga ma'auni (P), haɗin kai (I) da bambancin (D) na karkacewa shine mafi yawan amfani da mai sarrafa atomatik. Mai kula da PID yana amfani da ma'auni, haɗin kai, da bambanci don ƙididdige adadin sarrafawa bisa kuskuren tsarin don sarrafawa. Lokacin da tsari da sigogi na abin da aka sarrafa ba za a iya cika su ba, ko kuma ba za a iya samun ingantaccen tsarin lissafi ba, ko wasu fasahohin ka'idar sarrafawa suna da wuya a ɗauka, tsari da sigogi na mai sarrafa tsarin dole ne a ƙayyade ta hanyar kwarewa da kuma gyara kan shafin. A wannan lokacin, fasahar sarrafa PID aikace-aikacen ita ce mafi dacewa. Yin amfani da algorithm na sarrafa PID don sarrafa zafin jiki, yana da daidaito mai girma da kwanciyar hankali. Ana amfani da shi sau da yawa a cikin magunguna, sarrafa abinci, kimiyyar rayuwa da sauran lokuta waɗanda ke buƙatar daidaito mafi girma. Na dogon lokaci, masu kula da PID sun yi amfani da adadi mai yawa na ma'aikatan kimiyya da fasaha da masu aiki da filin, kuma sun tara kwarewa mai yawa.

 

Bugu da ƙari, bisa ga yanayin amfani daban-daban, ma'aunin zafi da sanyio yana da wasu hanyoyin rarrabuwa, kamar nau'in zafin jiki na ɗaki, nau'in zafin jiki na bene da nau'in zazzabi mai dual bisa ga hanyar ganowa; bisa ga bayyanar daban-daban, an raba su zuwa nau'in bugun kira na yau da kullun, nau'in maɓallin maɓalli na yau da kullun, nau'in LCD na fasaha mai zurfi, da sauransu. Daban-daban na thermostats suna da halaye daban-daban da yanayin aikace-aikacen, kuma masu amfani za su iya zaɓar daidai da ainihin buƙatu.
