Geely Emgrand X7. Manual part - 433
installed at one end of the evaporator and located at the inlet of the evaporator; one side of the expansion valve is Expansion valve changes the position from large to small according to the lower limit of the A/C pressure and the The evaporator is cooled and dehumidified before the air enters the passenger compartment. The following – Low pressure temperature fluid /vapor refrigerant enter into evaporator. – Refrigerant flows through evaporation pipe. – Refrigerant vaporizes. – Absorb heat, when refrigerant vaporises, air flow absorb heat by evaporator – Refrigerant enters into evaporator in the form of low pressure and low temperature, and leaves from evaporator in the form of steam. When the heat in air is transmitted to the evaporator core, moisture in air will be condensed on the outer surface of The evaporator is equipped with a temperature sensor to prevent from freezing. The sensor measures the surface 5. Refrigerant R-134a and lubricating oil Refrigerant function in the A/C system as follow: – Absorb heat – Carrying heat. – Release of heat The vehicle uses the R-134a refrigerant, which is a non-toxci, flame-retardant, transparent and colorleess liquefied Please refer to the instruction to the disposal of the refrigerant pipeline and connector as well as the maintenance The R-134a system is filled with the special-purpose lubricating oil FD46XG synthesized refrigerant oil which Be sure to repair as follow in accordance with the steps in the instruction: – Recycle and regeneration of refrigerant – Added oil – Drain out refrigeration System – Added refrigeration system again 6. A/C high pressure pipe belonged to the A/C low pressure pipe and the A/C pressure switch. 1731 |
