Izici Eziyinhloko Zokukhetha Uwoyela Wokupholisa

Ukukhetha uwoyela wokupholisa kufana nokuthola umlingani ofanele—ukuhambisana kubaluleke kakhulu kunokufaneleka kokuqala kuphela. Ngenxa yezimo ezihlukene zokusebenza ze-compressor kanye nezinto zokupholisa, ukukhethwa kowoyela wokupholisa kufanele kuhlangabezane nezidingo zempahla ethile. Nansi imingcele ebalulekile okufanele uyicabangele:

I-ViscosityIpharamitha ebalulekile: izinto zokupholisa ezihlukene zidinga ukuhambisana ne-viscosity yowoyela. I-viscosity ephezulu kakhulu ikhuphula amandla okuphazamiseka, ukukhiqizwa kokushisa kanye ne-torque yokwethula; i-viscosity ephansi kakhulu ayikwazi ukwenza ifilimu ewoyela ephumelelayo, ithinta ukugcoba nokupholisa. Uwoyela ongu-low-viscosity uncomekayo ukuze unciphise ukuphazamiseka nokuthuthukisa ukusebenza kwe-compressor, nakuba ungadala umsindo kumishini eshiywe isikhathi ngenxa yokunganele kokugcoba.

I-Cloud PointIzinga lokushisa lapho i-paraffin iqala ukuphuma futhi uwoyela uba mnyama. Kumele kube phansi kunezinga lokushisa lokuphuma kwezinto zokupholisa ukuze kugwenywe ukuvinjwa kwe-valve ye-throttle noma ukwehluleka kokudluliswa kokushisa.

Iphuzu LokubandaIzinga lokushisa lapho uwoyela umisa ukuhamba. Okuphansi kukhulu—amaphuzu okubanda aphezulu avimbela ukuhamba kwe-refrigerant, akhuphule ukumelana futhi anciphise ukusebenza kokudluliswa kokushisa. Kubalulekile ezindaweni zokuhlola eziphezulu zokushisa/nengcindezi noma ezokugcina ezibandayo eziphansi kakhulu.

Iphuzu LokukhanyaIzinga lokushisa elincane lapho umoya uwoyela uqala ukushisa lapho uthintana nomlilo. Kumele kube ngama-15–30℃ aphezulu kunokushisa kokuphuma kwe-compressor ukuze kuvinjwe ukushiswa kowoyela nokwakheka kwe-coke.

Ezinye IziciKubandakanya ukuzinza kwekhemikhali, ukumelana nokuphola, okuqukethwe kwamanzi/nokungcola kwemishini, kanye nokusebenza kokuhlukanisa.
