IiThermostats

I-Thermostats ngokubanzi iqulunqwe ngamalungu amabini: ukubonwa kobushushu kunye nolawulo lobushushu. Uninzi lwee-thermostats zine-alamu kunye nemisebenzi yokukhusela.

I-Thermostat, ngokwenguquko yobushushu bemeko-bume yokusebenza, ikhubaza ngokwasemzimbeni ngaphakathi kokutshintsha, ngaloo ndlela ivelisa iziphumo ezithile ezikhethekileyo, ivelisa uthotho lwezinto zolawulo oluzenzekelayo ngokuvula okanye ukucima izenzo, okanye ukubonelela ngedatha yobushushu kwisekethe. ngokwemigaqo yokusebenza eyahlukeneyo yamacandelo e-elektroniki kumaqondo obushushu ahlukeneyo, ukuze kuqokelelwe idatha yobushushu besekethe yonikezelo lwamandla. Iqondo lokushisa elilinganisiweyo lithathwa ngokuzenzekelayo kwaye libekwe esweni ngexesha langempela yinzwa yeqondo lokushisa. Xa iqondo lokushisa eliqokelelweyo liphezulu kunexabiso lesethi yolawulo, isiphaluka solawulo siqalisiwe, kwaye ukuhlukana kokubuyisela umva kunokusetwa. Ukuba iqondo lobushushu lisanyuka, qalisa umsebenzi we-alam ye-overrun xa ifika kwindawo ebekiweyo yobushushu be-alam. Xa ubushushu obulawulwayo bungenakulawulwa ngokufanelekileyo, ukuze kuthintelwe isixhobo ukuba singatshatyalaliswa, isixhobo sinokumiswa ukuze siqhubeke sibaleka ngomsebenzi wokukhubeka. Isetyenziswa ikakhulu kwiikhabhathi ezahlukeneyo zokuhambisa amandla ezisetyenziswa kumashishini ahlukeneyo, iifriji zasekhaya, izifudumezi zomoya kunye nezinye iindawo ezinxulumene nokusetyenziswa kobushushu.

Ngokobuchwephesha, iileya ezimbini zesinyithi ezinee-coefficients ezahlukeneyo zokwandiswa kwe-thermal zicinezelwe kunye. Xa ubushushu butshintsha, idigri yayo yokugoba iya kutshintsha. Xa igoba ukuya kwinqanaba elithile, isiphaluka siya kudibaniswa (okanye sinqanyulwe) ukwenza isixhobo sefriji (okanye ukufudumeza) sisebenze.

Ngombane, umqondiso wobushushu uguqulwa ube ngumqondiso wombane ngezixhobo zokuva ubushushu ezifana ne-thermocouples kunye neplatinam resistors, kwaye i-relay ilawulwa ziisekethe ezifana ne-microcomputer ye-chip enye kunye ne-PLC ukwenza ukufudumeza (okanye ukupholisa) umsebenzi wezixhobo (okanye umise).
