1.2 Mefuta e 'meli ea sehatsetsi sa compression
Boholo ba mekhahlelo e 'meli ea lihatsetsi tsa compression li khetha lihatsetsi tse mahareng le tse tlase tsa mocheso. Lipatlisiso tsa liteko li bonts'a hore R448A le R455a ke tse ling tse ntle bakeng sa R404A mabapi le ts'ebeliso e ntle ea matla. Ha e bapisoa le mefuta e meng ea li-hydrofluorocarbons, CO2, e le mokelikeli o sebetsang hantle oa tikoloho, e ka nkela lihatsetsi tsa hydrofluorocarbon sebaka 'me e na le litšobotsi tse ntle tsa tikoloho.
Empa ho nkela R134a sebaka ka CO2 ho tla senya ts'ebetso ea sistimi, haholoholo mochesong o phahameng oa tikoloho, khatello ea sistimi ea CO2 e phahame haholo mme e hloka kalafo e khethehileng ea likarolo tsa bohlokoa, haholo-holo compressor.
1.3 Patlisiso ea ntlafatso mabapi le sehatsetsi sa khatello ea mekhahlelo e 'meli
Hajoale, liphetho tsa lipatlisiso tsa ntlafatso ea sisteme ea mekhahlelo e 'meli ea sehatsetsing ke tse latelang:
(1) Ha o ntse o eketsa palo ea mela ea li-tube ho intercooler, ho fokotsa palo ea mela ea li-tube moeeng o pholileng ho ka eketsa sebaka sa phapanyetsano ea mocheso ea intercooler ha ho ntse ho fokotsa phallo ea moea e bakoang ke palo e kholo ea mela ea li-tube moeeng o pholileng. Ha u khutlela ho eona, ka lintlafatso tse ka holimo, mocheso o kenang oa intercooler o ka fokotsoa ka hoo e ka bang 2 ° C, 'me ka nako e ts'oanang, phello e pholileng ea moea o pholileng e ka tiisetsoa.
(2) Boloka khafetsa ea khatello e tlase ea khatello e sa fetohe, 'me u fetole makhetlo a mangata a khatello e phahameng ea khatello, kahoo u fetole tekanyo ea molumo oa phano ea khase ea khatello e phahameng ea khatello. Ha mocheso oa mouoane o lula o le -20 ° C, COP e phahameng ke 3.374, 'me e phahameng Karolelano ea phano ea khase e tsamaellanang le COP ke 1.819.
(3) Ka ho bapisa mekhoa e 'maloa e tloaelehileng ea CO2 ea mekhahlelo e' meli ea sehatsetsing, ho fihleloa hore mocheso oa mocheso oa mochine o pholileng oa khase le katleho ea mochine oa khatello e tlaase o na le tšusumetso e kholo ho potoloha ka khatello e fanoeng, kahoo haeba u batla ho ntlafatsa ts'ebetso ea tsamaiso, hoa hlokahala ho fokotsa mocheso oa sehatsetsing sa khase e pholileng 'me u khethe mochine o tlaase oa khatello e phahameng.
