Kapangidwe, dera, kuwongolera zamagetsi, makina owongolera ndi mfundo yogwirira ntchito ya makina oziziritsira mpweya wa magalimoto amagetsi
1. Kapangidwe ka makina oziziritsira mpweya a magalimoto atsopano amagetsi opanda mphamvu
Makina oziziritsira mpweya a magalimoto atsopano amagetsi okhala ndi mphamvu yeniyeni ndi ofanana ndi magalimoto achikhalidwe amafuta, okhala ndi ma compressor, ma condenser, ma evaporator, mafani ozizira, ma blowers, ma expansion valves ndi zida zapaipi zothamanga kwambiri komanso zochepa. Kusiyana kwake ndikuti zigawo zazikulu za makina atsopano amagetsi amagetsi okhala ndi mphamvu yeniyeni omwe amagwiritsidwa ntchito - compressor ilibe mphamvu yamagetsi yagalimoto yachikhalidwe, kotero imatha kuyendetsedwa ndi batri yamagetsi yagalimoto yokha, zomwe zimafuna kuwonjezera mota yoyendetsa mu compressor, kuphatikiza mota yoyendetsa ndi compressor ndi chowongolera, ndiko kuti, nthawi zambiri timati - compressor yozungulira yamagetsi.
2. Mfundo yoyendetsera makina atsopano oziziritsira mpweya wamagetsi amagetsi
Chowongolera magalimoto onse ∨CU chimasonkhanitsa chizindikiro cha AC switch cha air conditioner, chizindikiro cha pressure switch cha air conditioner, chizindikiro cha kutentha kwa evaporator, chizindikiro cha liwiro la mphepo ndi chizindikiro cha kutentha kwamlengalenga, kenako amapanga chizindikiro chowongolera kudzera mu basi ya CAN ndikuchitumiza kwa chowongolera mpweya. Kenako chowongolera mpweya chimayang'anira kuyatsidwa kwa dera lamagetsi lamphamvu la compressor ya air conditioner.
3. Mfundo yogwirira ntchito ya makina atsopano oziziritsira mpweya wamagetsi amagetsi
Chokometsera mpweya watsopano wamagetsi ndiye gwero la mphamvu yatsopano yamagetsi, apa tikusiyanitsa kuzizira ndi kutentha kwa mpweya watsopano wamagetsi:
(1) Mfundo yogwirira ntchito yoziziritsa mpweya m'magalimoto atsopano amagetsi opanda mphamvu
Pamene makina oziziritsira mpweya akugwira ntchito, makina oziziritsira mpweya amagetsi amachititsa kuti firiji iziyenda bwino mu makina oziziritsira mpweya, makina oziziritsira mpweya amagetsi amakanikiza firiji nthawi zonse ndikutumiza firiji ku bokosi loziziritsira mpweya, makina oziziritsira mpweya amayamwa kutentha mu bokosi loziziritsira mpweya ndikufutukuka, kotero kuti bokosi loziziritsira mpweya liziziritsidwa, kotero kuti mphepo yomwe imawomba ndi makina oziziritsira mpweya ndi mpweya wozizira.
(2) Mfundo yotenthetsera mpweya wabwino wa magalimoto atsopano amagetsi
Kutentha kwa mpweya woziziritsa mpweya kwa galimoto yachikhalidwe yamafuta kumadalira choziziritsira kutentha kwambiri mu injini, mutatsegula mpweya wofunda, choziziritsira kutentha kwambiri mu injini chidzadutsa mu thanki yofunda ya mpweya, ndipo mphepo yochokera ku chophulitsira mpweya idzadutsanso mu thanki yofunda ya mpweya, kotero kuti mpweya wotuluka mu choziziritsira mpweya ukhoza kutulutsa mpweya wofunda, koma mpweya woziziritsa mpweya wa galimoto yamagetsi chifukwa palibe injini, Pakadali pano, magalimoto ambiri atsopano omwe ali pamsika amakwaniritsa kutentha kwa magalimoto atsopano pogwiritsa ntchito chotenthetsera mpweya kapena chotenthetsera cha PTC.
(3) Mfundo yogwirira ntchito ya pampu yotenthetsera ndi iyi: mu ndondomeko yomwe ili pamwambapa, madzi otentha pang'ono (monga freon mu air conditioner) amasanduka nthunzi pambuyo poti achotsedwa ndi valavu ya throttle, amayamwa kutentha kuchokera kutentha kotsika (monga kunja kwa galimoto), kenako amakanikiza nthunzi ndi compressor, zomwe zimapangitsa kutentha kukwera, kutulutsa kutentha komwe kumayamwa kudzera mu condenser ndikusungunuka, kenako nkubwerera ku throttle. Kuzungulira kumeneku kumasamutsa kutentha kuchokera ku choziziritsira kupita ku malo otentha (omwe amafunika kutentha). Ukadaulo wa pampu yotenthetsera ukhoza kugwiritsa ntchito joule imodzi ya mphamvu ndikusuntha mphamvu zoposa joule imodzi (kapena ngakhale ma joule awiri) kuchokera kumalo ozizira, zomwe zimapangitsa kuti mphamvu zisamagwiritsidwe ntchito kwambiri.
(4) PTC ndi chidule cha Positive Temperature Coefficient (coefficient ya kutentha kwabwino), yomwe nthawi zambiri imatanthauza zinthu za semiconductor kapena zigawo zomwe zili ndi coefficient yayikulu ya kutentha kwabwino. Pochaja thermistor, kukana kumatentha kuti kukweze kutentha. PTC, pankhani yoopsa kwambiri, imatha kusintha mphamvu 100% yokha. Zimatengera joule imodzi ya mphamvu kuti ipange kutentha kopitilira joule imodzi. Chitsulo chamagetsi ndi chitsulo chopindika chomwe chimagwiritsidwa ntchito tsiku ndi tsiku zonse zimadalira mfundo iyi. Komabe, vuto lalikulu la kutentha kwa PTC ndi kugwiritsa ntchito mphamvu, zomwe zimakhudza kuchuluka kwa magalimoto amagetsi. Mwachitsanzo, kugwira ntchito ndi mphamvu zonse kwa ola limodzi kumadya 2kWh yamagetsi. Ngati galimoto iyenda makilomita 100 ndikugwiritsa ntchito 15kWh, 2kWh idzataya makilomita 13 a malo oyendetsera. Eni magalimoto ambiri akumpoto akudandaula kuti kuchuluka kwa magalimoto amagetsi kwachepa kwambiri, chifukwa cha kugwiritsa ntchito mphamvu kwa kutentha kwa PTC. Kuphatikiza apo, nthawi yozizira ikazizira, mphamvu ya batri yamagetsi imachepa, mphamvu yotulutsa siili yokwera, ndipo mtunda woyenda udzachepetsedwa.
Kusiyana pakati pa kutentha kwa PTC ndi kutentha kwa pampu yotenthetsera mpweya wamagetsi atsopano ndi kwakuti: Kutentha kwa PTC = kutentha kopangira, kutentha kwa pampu yotenthetsera = kutentha kosamalira.
