Abstract
A heat exchange system, an air conditioning control system, and an air conditioning system control method. A control portion of the heat exchange system respectively adjusts the opening of electronic expansion valves, and controls the electronic expansion valves to store an initialisation state and position information before powering down so that the electronic expansion valves first perform initialisation state switching when next powering up, thereby reducing the risk of the electronic expansion valves being out of step, and saving system start-up time.
