Pemampat Pemeluwap Penapis pengering Peranti pemeteran Penyejat Pensyarah menerangkan penggunaan peralatan pengujian untuk tujuan pemeriksaan komponen mekanikal. Pensyarah menerangkan kaedah pemeriksaan komponen mekanikal. Penilaian: Penilaian Amali
  6. Pensyarah menerangkan jenis –jenis pemampat Rotary Vane Rotary vane compressors consist of a rotor with three or four vanes and a carefully shaped rotor housing. As the compressor shaft rotates, the vanes and housing form chambers. The R134a is drawn through the suction port into these chambers, which become smaller as the rotor turns. The discharge port is located at the point where the gas is fully compressed. The vanes are sealed against the rotor housing by centrifugal force and lubricating oil. The oil sump and oil pump are located on the discharge side, so that the high pressure forces oil through the oil pump and then onto the base of the vanes keeping them sealed against the rotor housing. During idle an occasional vane noise from the compressor may be heard. This is due to the time taken for lubricating oil to circulate through the A/C system. Scroll type  This compressor uses a unique design with two scrolls, one fixed and one is movable, both are inter-leaved. The movable spiral is able to ORBIT to the input shaft via a concentric bearing. As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As these pockets decrease in size the refrigerant is squeezed, the pressure increases and is discharged through a reed valve at the discharge port in the rear section of the compressor. Wobble plate A reciprocating piston, fixed displacement compressor. The pistons are operated by a wobble plate, which moves them backwards and forwards in the cylinders. As the front shaft turns the wobble plate angle changes, causing the pistons to move in and out, pulling refrigerant vapor in through the suction side, compressing it and discharging this high pressure vapor into the condenser.
  7. Pensyarah menunjukkan video operasi pemampat. Pensyarah menanyakan pendapat pelajar berkenaan video tersebut.

Tekanan Silinder pengecas Timbang Pensyarah menerangkan peralatan yang digunakan untuk proses mengecas bahan pendingin. Pensyarah menerangkan proses mengecas menggunakan kaedah silinder pengecas: (demo) Langkah kerja: (Selepas proses pengosongan) Pasangkan tolok pancarongga: - Hos tekanan rendah > injap tekanan rendah sistem - Hos tekanan tinggi > injap tekanan tinggi sistem - Hos utiliti/servis > silinder pengecas Isikan cecair bahan pendingin ke dalam silinder pengecas. Labelkan aras kuantiti cecair bahan pedingin yang dikehendaki. Lakukan ‘purging’. (membuang lebihan udara dalam hos) Buka injap tekanan tinggi tolok pancarongga. (cecair bahan pendingin masuk) Tunggu sehingga cecair bahan pendingin didalam silinder pengecas turun ke takat yang dikehendaki Setelah cukup, tutup injap tekanan tinggi tolok pancarongga. Hidupkan enjin dan lihat bacaan tekanan rendah/tinggi sistem. Penilaian: Penilaian amali
  15. Pensyarah menerangkan proses mengecas bahan pendingin kaedah timbang. (demo) Langkah kerja: Pasangkan tolok pancarongga: - Hos tekanan rendah > injap tekanan rendah sistem - Hos tekanan tinggi > injap tekanan tinggi sistem - Hos utiliti/servis > silinder bahan pendingin Timbang berat asal silinder bahan pendingin – kuantiti bahan pendingin yang telah ditetapkan pengilang (Kenderaan).
