Abstract: This application provides a cooling system, including a heat exchanger, a cooling supplement component, a bypass vent valve, and a controller. The heat exchanger includes an air intake vent A and an air exhaust vent B that are used for outdoor fresh air entry and discharge, and an air intake vent C and an air exhaust vent D that are used for indoor return air entry and discharge. The cooling supplement component includes a condenser and an evaporator, the condenser is connected to the air exhaust vent B by using an exhaust air pipe, and the evaporator is connected to the air exhaust vent D. The bypass vent valve is disposed on the exhaust air pipe, and the bypass vent valve communicates with outdoor air. The bypass vent valve is connected to the controller, and the controller is configured to control the bypass vent valve.
