PURPOSE: A multi-cooling system for an air conditioner of a vehicle is provided to effectively cool an internal space of the vehicle when an engine stops. CONSTITUTION: A multi-cooling system for an air conditioner of a vehicle comprises a compressor part (110), a condenser part (120), a first refrigerant passage (140), an evaporator part (131), a second refrigerant passage (150), a cold storage module evaporator part (132), a third refrigerant passage (160), a first expansion valve (133), and a second expansion valve (134). The first refrigerant passage connects the compressor part and the condenser part to move a refrigerant discharged from the compressor. In order to move the refrigerant condensed by the condenser part to the evaporator part, the second refrigerant passage is branched from the first refrigerant passage and is connected to the evaporator part. In order to move the refrigerant condensed by the condenser part to the cold storage module evaporator part, the third refrigerant passage is branched from the first refrigerant passage and is connected to the cold storage module evaporator part. The cold storage module evaporator part and the evaporator part are branched from the first refrigerant passage in parallel. [Reference numerals] (110) Compressor part; (120) Condenser part; (131) Evaporator part; (132) Cold storage module evaporator part; (170) Control part; (210) Liquid receiver part; (220) Liquid separator part |
