Abstract

A cooling system includes a first heat exchanger, a second heat exchanger, a sensor module, and a processor. The first heat exchanger is configured to perform a first heat exchange process on an inlet gas having an inlet temperature using a first liquid. The second heat exchanger is configured to perform a second heat exchange process on the inlet gas after the first heat exchange process using a second liquid to form an outlet gas having an outlet temperature. The sensor module is configured to detect a first liquid temperature and a first flow rate of the first liquid, a second liquid temperature and a second flow rate of the second liquid, an inlet temperature, an outlet temperature, and a gas flow rate of the inlet gas. The processor is configured to determine whether at least one of the first and second heat exchangers is malfunctioning based on the parameters detected by the sensor module.
