PROBLEM TO BE SOLVED: To provide an automotive cooling equipment capable of shortening cool storing time by increasing a coolant supplying time ratio in a cool storage unit side while reducing fluctuation a blowing-out temperature by an evaporator into a car room. SOLUTION: Coolants compressed by a compressor 1 are liquefied by a condenser 2 and stored in a liquid receiver 3, the liquefied coolants from the liquid receiver 3 are expanded by an expansion valve 4 and supplied to an evaporator 6, cold is radiated to air to be sent into a car room, the coolants from the liquid receiver 3 are taken in alternatively by solenoid valves 11 and 12 to the evaporator 6, and these are expanded by an expansion valve 7 and supplied to a cool storage panel 9, and then stored. The coolants passed through the cool storage panel 9 are sent through the evaporator 6 to the compressor 1. By controlling the flow rate of the coolants from the expansion valve 7 based on a temperature in the exit side of the evaporator 6, a reduction in the flow rate of the coolants supplied to the cool storage panel 9 becomes difficult, and thus cool storing time is shortened.
