Pfupiso yeKutarisirwa kweThermal yeKabhini (Mota Dzinotonhodza Mhepo)

Sisitimu yekutonhodza mhepo yakakosha pakutarisira kupisa kwemotokari. Vatyairi nevafambi vanoda kunyaradzwa mumotokari dzavo. Basa guru rekutonhodza mhepo mumotokari nderekudzora tembiricha, hunyoro, uye kufamba kwemhepo mukati memukamuri wevafambi kuti pave nenzvimbo yekutyaira nekutyaira yakasununguka. Nheyo huru yekutonhodza mhepo mumotokari yakavakirwa panheyo yethermophysical yekupwanya kupisa nekudziya kunoburitsa kupisa, nokudaro kutonhora kana kudziyisa kabhini. Kana tembiricha yekunze yakaderera, inoendesa mhepo inopisa mukabhini, zvichiita kuti mutyairi nevafambi vasanyanya kutonhora; kana tembiricha yekunze yakakwira, inoendesa mhepo inotonhorera mukabhini, zvichiita kuti mutyairi nevafambi vanzwe kutonhora zvakanyanya. Naizvozvo, mhepo inotonhodza yemotokari inoita basa rakakosha mukutonhodza mhepo mukabhini uye kunyaradzwa kwevafambi. 

1.1 Sisitimu Yechinyakare Yekutonhodza Mhepo Yemotokari Inoshandisa Mafuta uye Nheyo Yekushanda Masisitimu echinyakare emota anoshandisa mafuta anosanganisira zvikamu zvina: evaporator, condenser, compressor, uye expansion valve. Air conditioner yemotokari inosanganisira refrigerator system, heating system, uye ventilation system; aya masystem matatu ndiwo anoumba air conditioner system yemota. Nheyo yekutonhodza mumota dzechinyakare dzinoshandisa mafuta inosanganisira matanho mana: kudzvanya, kunyorovesa, kuwedzera, uye evaporation. Nheyo yekudziya yemota dzechinyakare dzinoshandisa peturu inoshandisa kupisa kwakasviba kubva muinjini kupisa mukamuri revafambi. Kutanga, coolant inopisa kubva mujaketi remvura inotonhodza yeinjini inopinda mukati meheater. Fan inofuridza mhepo inotonhorera pamusoro peheater, uye mhepo inodziya inozofefeterwa mukamuri revafambi kuti idziye kana kunyungudutsa mahwindo. Coolant inozodzokera kuinjini mushure mekubuda muheater, ichipedzisa cycle imwe chete.

1.2 Sisitimu Itsva Yekutonhodza Mhepo Yemotokari Nemutemo Wekushanda

Nzira yekudziisa mota itsva ine simba yakasiyana zvikuru neyemotokari dzechinyakare dzinoshandisa peturu. Motokari dzechinyakare dzinoshandisa peturu dzinoshandisa kupisa kwemarara einjini kunoendeswa kunzvimbo yevatakurwi kuburikidza nechinhu chinotonhodza kuti dziwedzere tembiricha. Zvisinei, mota itsva dzine simba hadzina injini, saka hapana nzira yekudziisa inofambiswa neinjini. Saka, mota itsva dzine simba dzinoshandisa dzimwe nzira dzekudziisa. Nzira dzinoverengeka dzekudziisa mhepo inotonhodza mota itsva dzine simba dzakatsanangurwa pazasi. 

1) Positive Temperature Coefficient (PTC) Thermistor Heating: Chinhu chikuru chePTC ithermistor, iyo inodziiswa newaya inodziya, ichishandura simba remagetsi zvakananga kuita simba rinodziya. PTC (Potentially Transmitted Central) inotonhorera nemhepo inotsiva heater core yechinyakare mumotokari dzinoshandisa peturu nePTC heater. Fan inodhonza mhepo yekunze kuburikidza nePTC heater, yoidziisa, yozoendesa mhepo inodziya mukamuri revafambi. Nekuti inoshandisa magetsi zvakananga, simba rinoshandiswa nemotokari itsva rinokwira zvakanyanya kana heater ichibatidzwa.

 

2) PTC mvura inodziyakupisa: SezvakaitaPTC mhepo inodziyamasisitimu, masisitimu ePTC anotonhodzwa nemvura anogadzira kupisa nekushandisa magetsi. Zvisinei, sisitimu inotonhodzwa nemvura inotanga yapisa chinotonhodza nePTC hitaKana chinhu chinotonhodza chadziiswa kusvika patembiricha yakati, chinopombwa muchikamu cheheater, uko chinochinjana kupisa nemhepo yakapoteredza. Fan inobva yaendesa mhepo inodziya mukamuri revatakurwi kuti zvigaro zvidziyirwe. Chinhu chinotonhodza chinozodziiswa zvakare nePTC heater, uye kutenderera kunodzokororwa. Iyi sisitimu yekupisa yakavimbika uye yakachengeteka kupfuura masisitimu ePTC anotonhodza nemhepo.

 

3) Sisitimu Yekutonhodza Mhepo Inodziya: Nheyo yesisitimu yemhepo inotonhodza pombi yekupisa yakafanana neyesisitimu yemuchina wemotokari wemazuva ano wekutonhodza. Zvisinei, sisitimu yemhepo inotonhodza pombi yekupisa inogona kuchinja pakati pekupisa nekupisa mukamuri. Nekuti mhepo inotonhodza pombi yekupisa haishandisi simba remagetsi zvakananga pakudziisa, kushanda kwayo nesimba kwakanyanya kupfuura kwePTC heaters. Parizvino, masisitimu emhepo inotonhodza pombi yekupisa atove kugadzirwa mumotokari dzakawanda.
