62 - 7
The compressor is absorbing the vapors coming from the evaporator at low pressure and
temperature, is compressing them and convey the gas at high temperature and pressure. The refrigerant fluid in high pressure and temperature vapor condition is entering in the second
he at exchanger, which by condensation is transmitting the heat to the external environmental.
At the exit from the condenser, the refrigerant fl uid is in liquid condition, at a high pressure and temperature.
Type of compressor: SD 7Y15
Compressor oil : PAG SP 10 or SP20, volume –135 cmc.
Refrigerant: HFC 134 a, quantity of refrigerant : 0.590 kg
