Abstract
A dual type vehicle air conditioning system has a rear air conditioning system for rear seats and a front air conditioning system for front seats. The rear conditioning system has a rear conditioner unit defining a main air passage for directing inside air through an evaporator and a condenser in sequence. The rear conditioner unit further has a bypass air passage for introducing the inside air to the condenser, bypassing the evaporator, and an exhaust air passage for directing the inside air from the evaporator to the outside of the vehicle.
Claims17
A vehicle air conditioner comprising a first air conditioning system for taking in inside air, conditioning the inside air and supplying conditioned air to a first compartment of a vehicle and a second air conditioning system for selectively taking in the inside air and outside air, conditioning intake air and supplying conditioned air to a second compartment of the vehicle, wherein said first air conditioning system comprises:
- a refrigerant line comprising a circulation line introducing refrigerant discharged from a compressor, through a first condenser into a first evaporator connected in series with a second condenser, and a bypass line bypassing said first condenser;
