PURPOSE: A cooling system of a vehicle air conditioner is provided to improve the cooling performance by precisely regulating the flow rate of a coolant injector through electronic control. CONSTITUTION: A cooling system of a vehicle air conditioner includes a compressor, a condenser, a coolant flow rate control unit, and an evaporator. The compressor(10) compresses a coolant. The condenser(20) condenses the coolant supplied from the compressor to high pressure and high temperature coolant. The coolant flow rate control unit adjusts the flow rate of the coolant supplied from the condenser in order to convert it to low temperature and low pressure coolant. The evaporator(30) cools air by heat exchange between the air and the coolant supplied from the coolant flow rate control unit. The coolant flow rate control unit comprises a chamber part(40) formed on a coolant pipe between the evaporator and the condenser, a coolant injector(50) mounted inside the connection pipe extended from the front of the chamber part, and a controller(60) controlling the coolant flow of the coolant injector. |
