Ho kgetha mokelikeli o nepahetseng wa phetisetso ya mocheso (HTF) ho hloka ho leka-lekanya dintlha tse ngata tsa botekgeniki le tsa tshebetso ho fihlella tshebetso e tshepahalang, polokeho le katleho ya ditjeo. Le hoja qeto e ka bonahala e le thata, ho tsepamisa maikutlo hodima maemo a mmalwa a motheo ho ka nolofatsa tshebetso ya tlhahlobo.
Mocheso e le Tataiso e ka Sehloohong
Sefe ea bohlokoa ka ho fetisisa ke mocheso o sebetsang oa sistimi ea hau. Ho latela sena, maro a oela likarolong tse peli tse kholo:
• Ditshebediso tsa Mocheso o Phahameng (>175°C / 350°F): Bakeng sa maemo ana a boima, ho kgothaletswa maro a maiketsetso a tlhaho kapa maro a thehilweng ho silicone. A boloka botsitso ba mocheso ho fihlela ho hoo e ka bang 400°C (750°F), a bontsha kgatello e tlase ya mouoane ha a bapiswa le ditsamaiso tsa mouoane, mme a fana ka tshebetso e tshepahalang ho pholletsa le nako e pharaletseng ya mocheso, a netefatsa hore ho na le botsitso ba mocheso o phahameng le ho pompa mocheso o tlase.
• Ditshebediso tse Sireleditsweng ke Mocheso o Mahareng/o Tlase kapa o Sireleditsweng ke Hoamisa (≤175°C / 350°F): Metswako ya glycol-metsi e thibetsweng hangata ke tharollo e kgethwang. Metsi ana a fana ka phetiso e sebetsang ya mocheso hammoho le tshireletso ya hoamisa, e leng se etsang hore a lokele ditsamaiso tse pepesehetseng dibakeng tse batang.
Khetho ea Mokelikeli o Thehiloeng ho Glycol: Ethylene khahlanong le Propylene
Haeba mokelikeli o thehiloeng ho glycol o lumellana le litlhoko tsa hau tsa mocheso, qeto e latelang e kenyelletsa mofuta oa motheo oa glycol:
• Metsi a Thehiloeng ho Ethylene Glycol (EG):Hangata li khethoa ka lebaka la ho ba le viscosity e tlase, e leng se ntlafatsang katleho ea phetisetso ea mocheso le ho fokotsa matla a ho pompa. Li emela khetho e theko e tlaase le e sebetsang hantle bakeng sa litsamaiso tse ngata tsa indasteri tse koetsoeng.
• Metsi a Thehiloeng ho Propylene Glycol (PG):E kgethilwe ha chefo e tlase e le ntho ya bohlokwa. Metsi a PG hangata a hlaloswa ditshebedisong tse ka bang haufi le phepelo ya dijo, metsi a nowang, kapa dibakeng tseo ho dutla ha metsi ho bakang tshireletso kapa kgathatso ya tikoloho.
Ka Nģ'ane ho Mocheso: Lintlha tse ling tsa Khetho
Leha mocheso le mofuta wa mokelikeli di fana ka ntlha e matla ya ho qala, tlhahlobo e felletseng e lokela ho nahana ka:
• Ho tsitsa ha mocheso le bophelo bo lebelletsoeng ba tšebeletso ea mokelikeli.
• Boitšoaro ba ho pompa le ho teteana ho pholletsa le sebaka sa ts'ebetso.
• Ho tsamaellana ha thepa le likarolo tsa sistimi.
• Litlhoko tsa polokeho, tikoloho le melaoana.
• Kakaretso ea litšenyehelo tsa beng, ho kenyeletsoa le linako tsa tlhokomelo le tsa ho nkela mokelikeli sebaka.
Mokhoa o hlophisitsoeng oa ho khetha HTF—ho qala ka litlhoko tsa mocheso le lithibelo tse ikhethileng tsa ts'ebeliso—o netefatsa hore mokelikeli o khethiloeng o tšehetsa katleho ea sistimi ea nako e telele, polokeho le moruo oa ts'ebetso.
